RESUMEN

The study of the perceived affective qualities (PAQs) in soundscape assessments have increased in recent years, with methods varying from in-situ to laboratory. Through technological advances, virtual reality (VR) has facilitated evaluations of multiple locations in the same experiment. In this paper, VR reproductions of different urban sites were presented in an online and laboratory environment testing three locations in Greater Manchester ('Park', 'Plaza', and pedestrian 'Street') in two population densities (empty and busy) using ISO/TS 12913-2 (2018) soundscape PAQs. The studied areas had audio and video recordings prepared for 360 video and binaural audio VR reproductions. The aims were to observe population density effects within locations (Wilcoxon test) and variations between locations (Mann-Whitney U test) within methods. Population density and comparisons among locations demonstrated a significant effect on most PAQs. Results also suggested that big cities can present homogenous sounds, composing a 'blended' urban soundscape, independently of functionality. These findings can support urban design in a low-cost approach, where urban planners can test different scenarios and interventions.

RESUMEN

Exposure to loud sound during leisure time is identified as a significant risk factor for hearing by health authorities worldwide. The current standard that defines unsafe exposure rests on the equal-energy hypothesis, according to which the maximum recommended exposure is a tradeoff between level and daily exposure duration, a satisfactory recipe except for strongly non-Gaussian intense sounds such as gunshots. Nowadays, sound broadcast by music and videoconference streaming services makes extensive use of numerical dynamic range compression. By filling in millisecond-long valleys in the signal to prevent competing noise from masking, it pulls sound-level statistics away from a Gaussian distribution, the framework where the equal-energy hypothesis emerged. Auditory effects of a single 4 hour exposure to the same music were compared in two samples of guinea pigs exposed either to its original or overcompressed version played at the same average level of 102 dBA allowed by French regulations. Apart from a temporary shift of otoacoustic emissions at the lowest two frequencies 2 and 3 kHz, music exposure had no detectable cochlear effect, as monitored at 1, 2 and 7 days post-exposure. Conversely, middle-ear muscle strength behaved differentially as the group exposed to original music had fully recovered one day after exposure whereas the group exposed to overcompressed music remained stuck to about 50% of baseline even after 7 days. Subsamples were then re-exposed to the same music as the first time and sacrificed for density measurements of inner-hair-cell synapses. No difference in synaptic density was found compared to unexposed controls with either type of music. The present results show that the same music piece, harmless when played in its original version, induces a protracted deficit of one auditory neural pathway when overcompressed at the same level. The induced disorder does not seem to involve inner-hair cell synapses.

RESUMEN

The discovery and development of electrocochleography (ECochG) in animal models has been fundamental for its implementation in clinical audiology and neurotology. In our laboratory, the use of round-window ECochG recordings in chinchillas has allowed a better understanding of auditory efferent functioning. In previous works, we gave evidence of the corticofugal modulation of auditory-nerve and cochlear responses during visual attention and working memory. However, whether these cognitive top-down mechanisms to the most peripheral structures of the auditory pathway are also active during audiovisual crossmodal stimulation is unknown. Here, we introduce a new technique, wireless ECochG to record compound-action potentials of the auditory nerve (CAP), cochlear microphonics (CM), and round-window noise (RWN) in awake chinchillas during a paradigm of crossmodal (visual and auditory) stimulation. We compared ECochG data obtained from four awake chinchillas recorded with a wireless ECochG system with wired ECochG recordings from six anesthetized animals. Although ECochG experiments with the wireless system had a lower signal-to-noise ratio than wired recordings, their quality was sufficient to compare ECochG potentials in awake crossmodal conditions. We found non-significant differences in CAP and CM amplitudes in response to audiovisual stimulation compared to auditory stimulation alone (clicks and tones). On the other hand, spontaneous auditory-nerve activity (RWN) was modulated by visual crossmodal stimulation, suggesting that visual crossmodal simulation can modulate spontaneous but not evoked auditory-nerve activity. However, given the limited sample of 10 animals (4 wireless and 6 wired), these results should be interpreted cautiously. Future experiments are required to substantiate these conclusions. In addition, we introduce the use of wireless ECochG in animal models as a useful tool for translational research.

RESUMEN

OBJECTIVE: To describe and analyze auditory and academic complaints of students and employees of a federal public university. METHODS: The study was carried out using a non-probabilistic. The EAPAC Scale with adaptations was used to fulfill the research objectives. It has 14 questions about complaints related to listening skills and 12 questions related to the academic environment. Descriptive data analysis was performed through the frequency distribution of categorical variables and Pearson's chi-square test was used for association analyses. RESULTS: 646 individuals aged between 17 and 67 years old participated in the research. The most prevalent complaints were academic difficulty related to memory, concentration, and planning, hearing and understanding speech in noise, and memorization of tasks that were only heard. There was an association with bidirectional statistical significance between academic and auditory complaints. CONCLUSION: It was possible to observe that there is an association between auditory and academic complaints in adults, marked by the relationship between cognitive and auditory aspects. It is relevant that these factors are considered when performing assessments of Central Auditory Processing when intervening in patients with auditory complaints, and in student life.

RESUMEN

BACKGROUND The dichotic digit test (DDT) is one of the tests for the behavioral assessment of central auditory processing. Dichotic listening tests are sensitive ways of assessing cortical structures, the corpus callossum, and binaural integration mechanisms, showing strong correlations with learning difficulties. The DDT is presently available in a number of languages, each appropriate for the subject's native language. However, there is presently no test in the Italian language. The goal of this study was to develop an Italian version of the one-pair dichotic digit test (DDT-IT) and analyze results in 39 normal-hearing Italian children 11 to 13 years old. We used 2 conditions of presentation: free recall and directed attention (left or right ear), and looked at possible effects of sex and ear side. MATERIAL AND METHODS This study involved 3 steps: creation of the stimuli, checking their quality with Italian speakers, and assessment of the DDT-IT in our subject pool. The study involved 39 children (26 girls and 13 boys), aged 11-13 years. All participants underwent basic audiological assessment, auditory brainstem response, and then DDT-IT. RESULTS Results under free recall and directed attention conditions were similar for right and left ears, and there were no sex or age effects. CONCLUSIONS The Italian version of DDT (DDT-IT) has been developed and its performance on 39 normal-hearing Italian children was assessed. We found there were no age or sex effects for either the free recall condition or the directed attention condition.

RESUMEN

INTRODUCTION: Attention and working memory are key cognitive functions that allow us to select and maintain information in our mind for a short time, being essential for our daily life and, in particular, for learning and academic performance. It has been shown that musical training can improve working memory performance, but it is still unclear if and how the neural mechanisms of working memory and particularly attention are implicated in this process. In this work, we aimed to identify the oscillatory signature of bimodal attention and working memory that contributes to improved working memory in musically trained children. MATERIALS AND METHODS: We recruited children with and without musical training and asked them to complete a bimodal (auditory/visual) attention and working memory task, whereas their brain activity was measured using electroencephalography. Behavioral, time-frequency, and source reconstruction analyses were made. RESULTS: Results showed that, overall, musically trained children performed better on the task than children without musical training. When comparing musically trained children with children without musical training, we found modulations in the alpha band pre-stimuli onset and the beginning of stimuli onset in the frontal and parietal regions. These correlated with correct responses to the attended modality. Moreover, during the end phase of stimuli presentation, we found modulations correlating with correct responses independent of attention condition in the theta and alpha bands, in the left frontal and right parietal regions. CONCLUSIONS: These results suggest that musically trained children have improved neuronal mechanisms for both attention allocation and memory encoding. Our results can be important for developing interventions for people with attention and working memory difficulties.

RESUMEN

PURPOSE: To correlate behavioral assessment results of central auditory processing and the self-perception questionnaire after acoustically controlled auditory training. METHODS: The study assessed 10 individuals with a mean age of 44.5 years who had suffered mild traumatic brain injury. They underwent behavioral assessment of central auditory processing and answered the Formal Auditory Training self-perception questionnaire after the therapeutic intervention - whose questions address auditory perception, understanding orders, request to repeat statements, occurrence of misunderstandings, attention span, auditory performance in noisy environments, telephone communication, and self-esteem. Patients were asked to indicate the frequency with which the listed behaviors occurred. RESULTS: Figure-ground, sequential memory for sounds, and temporal processing correlated with improvement in following instructions, fewer requests to repeat statements, increased attention span, improved communication, and understanding on the phone and when watching TV. CONCLUSION: Auditory closure, figure-ground, and temporal processing had improved in the assessment after the acoustically controlled auditory training, and there were fewer auditory behavior complaints.

OBJETIVO: Correlacionar os resultados da avaliação comportamental do processamento auditivo central e do questionário de autopercepção após o treinamento auditivo acusticamente controlado. MÉTODO: Foram avaliados dez indivíduos com média de idade de 44,5 anos, que sofreram traumatismo cranioencefálico de grau leve. Os indivíduos foram submetidos a avaliação comportamental do processamento auditivo central e também responderam ao questionário de autopercepção "Treinamento Auditivo Formal" após a intervenção terapêutica. O questionário foi composto por questões referentes a percepção auditiva, compreensão de ordens, solicitação de repetição de enunciados, ocorrência mal-entendidos, tempo de atenção, desempenho auditivo em ambiente ruidoso, comunicação ao telefone e autoestima e os pacientes foram solicitados a assinalar a frequência de ocorrência dos comportamentos listados. RESULTADOS: As habilidades auditivas de figura-fundo e memória para sons em sequência e processamento temporal correlacionaram-se com melhora para seguir instruções, diminuição das solicitações de repetições e aumento do tempo de atenção e melhora da comunicação e da compreensão ao telefone e para assistir TV. CONCLUSÃO: Observou-se adequação das habilidades auditivas de fechamento auditivo, figura fundo, e processamento temporal na avaliação pós-treinamento auditivo acusticamente controlado, além de redução das queixas quanto ao comportamento auditivo.

RESUMEN

PURPOSE: To compare the acoustic measurements of Cepstral Peak Prominence Smoothed (CPPS) and Acoustic Voice Quality Index (AVQI) of children with normal and altered voices, to relationship with auditory-perceptual judgment (APJ) and to establish cut-off points. METHODS: Vocal recordings of the sustained vowel and number counting tasks of 185 children were selected from a database and submitted to acoustic analysis with extraction of CPPS and AVQI measurements, and to APJ. The APJ was performed individually for each task, classified as normal or altered, and for the tasks together defining whether the child would pass or fail in a situation of vocal screening. RESULTS: Children with altered APJ and who failed the screening had lower CPPS values and higher AVQI values, than those with normal APJ and who passed the screening. The APJ of the sustained vowel task was related to CPPS and AVQI, and APJ of the number counting task was related only to AVQI and CPPS numbers. The cut-off points that differentiate children with and without vocal deviation are 14.07 for the vowel CPPS, 7.62 for the CPPS numbers and 2.01 for the AVQI. CONCLUSION: Children with altered voices, have higher AVQI values and lower CPPS values, when detected in children with voices within the normal range. The acoustic measurements were related to the auditory perceptual judgment of vocal quality in the sustained vowel task, however, the number counting task was related only to the AVQI and CPPS. The cut-off points that differentiate children with and without vocal deviation are 14.07 for the CPPS vowel, 7.62 for the CPPS numbers and 2.01 for the AVQI. The three measures were similar in identifying voices without deviation and dysphonic voices.

OBJETIVO: Comparar as medidas acústicas de Cepstral Peak Prominence Smoothed (CPPS) e Acoustic Voice Quality Index (AVQI) de crianças com vozes normais e alteradas, relacionar com o julgamento perceptivo-auditivo (JPA) da voz e estabelecer pontos de corte. MÉTODO: Gravações vocais das tarefas de vogal sustentada e contagem de números de 185 crianças foram selecionadas em um banco de dados e submetidas a análise acústica com extração das medidas de CPPS e AVQI, e ao JPA. O JPA foi realizado individualmente para cada tarefa e as amostras foram classificadas posteriormente como normal ou alterada, e para as tarefas em conjunto definindo-se se a criança passaria ou falharia em uma situação de triagem vocal. RESULTADOS: Crianças com JPA alterado e que falharam na triagem apresentaram valores menores de CPPS e maiores de AVQI, do que as com JPA normal e que passaram na triagem. O JPA da tarefa de vogal sustentada se relacionou ao CPPS e AVQI, e da tarefa de contagem de números relacionou-se apenas ao AVQI e CPPS números. Os pontos de corte que diferenciam crianças com e sem desvio vocal são 14,07 para o CPPS vogal, 7,62 para o CPPS números e 2,01 para o AVQI. CONCLUSÃO: Crianças com JPA alterado apresentaram maiores valores de AVQI e menores valores de CPPs. O JPA da tarefa de vogal previu todas as medidas acústicas, porém, de contagem previu apenas as medidas extraídas dela. As três medidas foram semelhantes na identificação de vozes sem desvio e vozes disfônicas.

RESUMEN

OBJECTIVES: Our study aimed to verify the evidence of auditory training employed in the audiological treatment of tinnitus in adults and older adults. METHODS: Scoping review based on a search for articles in journals available in MEDLINE (PubMed), Embase (Elsevier), LILACS (BVS), and Cochrane Library. Titles and abstracts of the retrieved articles were assessed by peers, following the eligibility criteria; they were afterward read in full text, and the references were hand searched in the results found. Studies' level of evidence was classified into very high (Level A+), high (Level A), moderate (Level B), limited (Level C), low (Level D), or very low (Level D-) based on the Critically Appraised Topics. RESULTS: 2160 records were identified in the searching stage and 15 studies were eligible for data extraction. Study design, sample characterization, auditory training tasks, sound stimuli, outcome measures, and results were extracted. Frequency discrimination training was the most frequent strategy, followed by auditory attentional skills training and multisensory training. Almost all studies with daily auditory training sessions reported significant benefits demonstrated in at least one outcome measure. Studies that used auditory discrimination training and attentional auditory skill stimulation to treat tinnitus obtained quality evidence levels ranging from limited to high (C‒A) and studies that applied multisensory training or attentional training combined with counseling and passive listening in tinnitus patients reached a high-quality evidence level (A). CONCLUSION: Recent studies had higher levels of evidence and considered attentional factors and multisensory pathways in auditory training strategies.

RESUMEN

INTRODUCTION: The auditory perception of voice and its production involve auditory feedback, kinesthetic cues and the feedforward system that produce different effects for the voice. The Lombard, Sidetone and Pitch-Shift-Reflex effects are the most studied. The mapping of scientific experiments on changes in auditory feedback for voice motor control makes it possible to examine the existing literature on the phenomenon and may contribute to voice training or therapies. PURPOSE: To map experiments and research results with manipulation of auditory feedback for voice motor control in adults. METHOD: Scope review following the Checklist Preferred Reporting Items for Systematic reviews and Meta-Analyses extension (PRISMA-ScR) to answer the question: "What are the investigation methods and main research findings on the manipulation of auditory feedback in voice self-monitoring of adults?". The search protocol was based on the Population, Concept, and Context (PCC) mnemonic strategy, in which the population is adult individuals, the concept is the manipulation of auditory feedback and the context is on motor voice control. Articles were searched in the databases: BVS/Virtual Health Library, MEDLINE/Medical Literature Analysis and Retrieval System online, COCHRANE, CINAHL/Cumulative Index to Nursing and Allied Health Literature, SCOPUS and WEB OF SCIENCE. RESULTS: 60 articles were found, 19 on the Lombard Effect, 25 on the Pitch-shift-reflex effect, 12 on the Sidetone effect and four on the Sidetone/Lombard effect. The studies are in agreement that the insertion of a noise that masks the auditory feedback causes an increase in the individual's speech intensity and that the amplification of the auditory feedback promotes the reduction of the sound pressure level in the voice production. A reflex response to the change in pitch is observed in the auditory feedback, however, with particular characteristics in each study. CONCLUSION: The material and method of the experiments are different, there are no standardizations in the tasks, the samples are varied and often reduced. The methodological diversity makes it difficult to generalize the results. The main findings of research on auditory feedback on voice motor control confirm that in the suppression of auditory feedback, the individual tends to increase the intensity of the voice. In auditory feedback amplification, the individual decreases the intensity and has greater control over the fundamental frequency, and in frequency manipulations, the individual tends to correct the manipulation. The few studies with dysphonic individuals show that they behave differently from non-dysphonic individuals.

INTRODUçÃO: A percepção auditiva da voz e sua produção envolvem o feedback auditivo, as pistas cinestésicas e o sistema de feedforward, os quais produzem efeitos distintos para a voz. Os efeitos Lombard, Sidetone e o Pitch-Shift-Reflex são os mais estudados. O mapeamento de experimentos científicos sobre as modificações do feedback auditivo para o controle motor da voz possibilita examinar a literatura existente sobre o fenômeno e pode contribuir para o treinamento ou terapias da voz. OBJETIVO: Mapear os experimentos e resultados das pesquisas com manipulação do feedback auditivo para o controle motor da voz de indivíduos adultos. MÉTODO: Revisão de escopo seguindo o Checklist Preferred Reporting Items for Systematic reviews and Meta-Analyses extension (PRISMA-ScR) para responder à pergunta: "Quais os métodos de investigação e principais achados das pesquisas sobre a manipulação do feedback auditivo no automonitoramento da voz de indivíduos adultos?". O protocolo de busca foi baseado na estratégia mnemônica População, Conceito e Contexto (PCC). A população são os indivíduos adultos; o conceito é a manipulação do feedback auditivo e o contexto é o controle motor da voz. Os artigos foram pesquisados nas bases de dados: BVS/ Biblioteca Virtual em Saúde, MEDLINE/Medical Literature Analysis and Retrieval Sistem on-line, COCHRANE, CINAHL/Cumulative Index to Nursing and Allied Health Literature, SCOPUS e WEB OF SCIENCE. RESULTADOS: Foram encontrados 60 artigos, sendo 19 da temática do Efeito Lombard, 25 do efeito Pitch-shift-reflex, 12 do efeito Sidetone e quatro sobre o efeito Sidetone/Lombard. Os estudos são concordantes que a inserção de um ruído que mascara o feedback auditivo provoca um aumento na intensidade de fala do indivíduo e que a amplificação do feedback auditivo promove a redução do nível de pressão sonora na produção da voz. Observa-se uma resposta reflexa à mudança de tom no feedback auditivo, porém, com características individuais em cada estudo. CONCLUSÃO: O material e método dos experimentos são distintos, não há padronizações nas tarefas, as amostras são variadas, muitas vezes reduzidas. A diversidade metodológica dificulta a generalização dos resultados. Os principais achados das pesquisas a respeito o feedback auditivo sobre o controle motor da voz confirmam que, na supressão do feedback auditivo, o indivíduo tende a aumentar a intensidade da voz. Na amplificação do feedback auditivo, o indivíduo diminui a intensidade e tem maior controle sobre a frequência fundamental e, nas manipulações da frequência, o indivíduo tende a corrigir a manipulação. Os poucos estudos com sujeitos disfônicos mostram que eles se comportam diferentemente dos não disfônicos.

RESUMEN

PURPOSE: The purpose of this study was to investigate the effectiveness of using computerized auditory training in the auditory perception of speech in children who use electronic devices through a systematic review of the literature. METHOD: This is a systematic review based on the elaboration of the following guiding question: In hearing-impaired children who use electronic devices, how effective is the use of computerized auditory training in the auditory perception of speech? The Cochrane Library, Embase, LILACS, PubMed, Web of Science, and Scopus databases and gray literature (Google Scholar and ProQuest) were consulted. RESULTS: Nine hundred and eighteen records were identified, with additional two studies in the citation search, totaling 920 studies. After excluding the 184 duplicate references, using the Rayyan platform, the titles and abstracts were screened (n = 736), with 20 studies selected and considered for full reading. Six of the 20 studies were included in the systematic review of the literature. CONCLUSIONS: Positive and beneficial results regarding computerized auditory training are evidenced, which describe and discuss the proof of the effectiveness of the positive effects on the auditory perception of speech in children using hearing aids and cochlear implants with regard to auditory detection skills, discrimination, recognition, and auditory memory. The positive results are inspiring for the continuity and expansion of studies that further investigate the use of computerized auditory training with contemporary technologies and have an impact on the improvement of access to specialized intervention.

RESUMEN

PURPOSE: This study aimed to analyze the auditory processing behavior of children and adolescents diagnosed with stroke and compare it with that of typically developing individuals. METHODS: This was an analytical cross-sectional study involving 48 participants aged between 7 and 17 years with adequate schooling for age and grade, allocated equally to two groups: Stroke (SG) and Control Groups (CG). For the SG, cases identified between 2003 and 2018 were considered. In the CG, school-aged participants with typical development were randomized. After screening for differential audiological assessment and confirmation of auditory pathway integrity at the brainstem level, binaural analyses of the auditory processing behavior were conducted using the Dichotic Digit Test (DDT), Frequency Pattern Test (FPT), and electrophysiological assessment (P300). The Shapiro-Wilk test for normality was conducted, followed by the T and Mann-Whitney tests, with a 95 % confidence level and significance offset at p < 0.05, using the SPSS software (IBM®, v. 22.) RESULTS: The CG performed better in terms of auditory processing. These differences were significant (p < 0.0001) for the binaural integration of DDT, FPT humming and Labeling, and P300 latency. The P300 results were similar; however, with a greater amplitude in the SG. CONCLUSION: This study showed that children and adolescents with stroke performed worse in electrophysiological and behavioral tests of auditory processing assessed using the auditory evoked potentials. These data reinforce the hypothesis that stroke-related lesions compromise the neural mechanisms underlying auditory processing.

RESUMEN

Introdução: A atuação profissional com bebês e crianças pequenas com deficiência auditiva exige conhecimento e técnica específica no que diz respeito à prescrição e adaptação do aparelho de amplificação sonora individual (AASI) e ao processo de desenvolvimento de linguagem. Limitações e imprecisões ao longo do processo diagnóstico poderão comprometer todos os procedimentos subsequentes do processo de intervenção. Objetivo: Analisar a validação do processo de diagnóstico audiológico e intervenção em bebês e crianças com deficiência auditiva a partir da análise comparativa de exames audiológicos, comportamento auditivo e aplicação do princípio de verificação cruzada após adaptação de AASI. Método: Foram sujeitos da pesquisa 12 crianças de até 36 meses de idade, com diagnóstico de perda auditiva neurossensorial bilateral, selecionados a partir da disponibilidade de acesso ao serviço para a avaliação e agrupados em G1 (sujeitos com Índice de Inteligibilidade de Fala - SII 65 dB até 35%) e G2 (sujeitos com Índice de Inteligibilidade de Fala - SII 65 dB acima de 54%). Resultados: A média de idade do diagnóstico audiológico foi de 4,33 meses. Os resultados audiológicos de todas as crianças tiveram correspondência entre si, com exceção de dois sujeitos do G2. Conclusão: O comportamento auditivo não só permitiu a validação dos processos de diagnóstico e intervenção auditiva dos sujeitos da pesquisa, como também permitiu a identificação de comportamentos não compatíveis com a audibilidade devido ao uso inconsistente dos AASI. A aplicação dos instrumentos de acompanhamento de desenvolvimento mostrou-se adequada para o monitoramento do desenvolvimento de habilidades de audição e linguagem em crianças pequenas. (AU)

Introduction: Professional work with infants and young children with hearing impairment requires specific knowledge and technique regarding the prescription and adaptation of the individual sound amplification device (PSAD) and the language development process. Limitations and inaccuracies throughout the diagnostic process may compromise all subsequent procedures of the intervention process. Purpose: To analyze the validation of the process of audiological diagnosis and intervention in infants and children with hearing impairment based on the comparative analysis of audiological tests, auditory behavior and application of the cross-checking principle after adaptation of hearing aids. Method: The research subjects were 12 children aged up to 36 months, with a diagnosis of bilateral sensorineural hearing loss, selected from the availability of access to the service for the evaluation and grouped into G1 (subjects with Speech Intelligibility Index - SII 65 dB up to 35%) and G2 (subjects with Speech Intelligibility Index - SII 65 dB above 54%). Results: The average age of the audiological diagnosis was 4.33 months. The audiological results of all children corresponded to each other, except for two subjects from G2. Conclusion: The auditory behavior not only allowed the validation of the processes of diagnosis and auditory intervention of the research subjects, but also allowed the identification of behaviors that are not compatible with audibility due to the inconsistent use of hearing aids. The application of developmental monitoring instruments proved to be adequate for monitoring the development of hearing and language skills in young children. (AU)

RESUMEN

With the objective of outlining the current knowledge available on the health and well-being of older people in the Region of the Americas at the start of the United Nations Decade of Healthy Aging 2021–2030, this report details the current state of visual and hearing health of older people in the Region of the Americas. Its purpose is to inform, providing evidence and specific information on the needs of this population in these two fundamental areas of intrinsic capacity, which constitute the main causes of disability in the Region's older adults. The information provided should contribute to the implementation of strategic regional actions that promote ongoing improvement in the health of older people. Accelerated population aging in Latin America and the Caribbean shapes, and will continue to shape, the capacity of countries and health systems to respond to the specific needs of the population. In order to design inclusive and sustainable systems, it is therefore necessary to have reliable up-to date information to aid in decision-making. During the Decade of Healthy Aging 2021–2030, actions should be geared toward generating and monitoring data, and the present report contributesto this objective.

RESUMEN

PURPOSE: To describe the development and validation of a test, called BATUTA, that assesses the musical perception of people with hearing impairment that are hearing aid (HA) users. BATUTA is a computerized test with 35 subtests, divided into the rhythm, pitch, and timbre modules, and the participants must answer whether the sound samples and/or parts of the songs, presented in pairs, are the same or not. METHODS: The BATUTA creation process consisted of four stages: test development, submission to the expert committee for content validation; pilot application with 51 normal hearing participants and retest to validate reliability. The process was based on several recommendations for the development and validation of musical assessment instruments. A deep investigation of the guidelines related to sound samples used, musical attributes evaluated, testing environment and the most appropriate response method was undertaken to ensure dependability. RESULTS: The Content Validity Index (CVI) and expert agreement rates, when analyzed with the committee's recommendations, resulted in corrections and new audio recordings to ensure compliance to the test. The pilot test scores indicated internal consistency and the retest confirmed the reliability of BATUTA. CONCLUSION: The results demonstrated the viability of BATUTA to assess the musical perception of people with hearing impairment that are HA users.

OBJETIVO: Descrever o desenvolvimento e a validação de um teste de percepção musical, denominado BATUTA, destinado a avaliar a percepção musical de pessoas com deficiência auditiva, usuárias de aparelhos de amplificação sonora individual (AASI). O BATUTA é um teste computadorizado composto por 35 subtestes divididos nos módulos ritmo, pitch e timbre para os quais os participantes devem responder se as amostras sonoras e/ou os trechos musicais apresentados, aos pares, são iguais ou diferentes. MÉTODO: O processo de construção do BATUTA foi composto por quatro etapas: desenvolvimento do teste, submissão da versão inicial ao comitê de especialistas para validação de conteúdo; aplicação do piloto em 51 participantes com audição normal e reteste para validação da confiabilidade, fundamentadas em reconhecidas recomendações para elaboração e validação de instrumentos de avaliação. Diretrizes relacionadas à natureza das amostras sonoras utilizadas, aos atributos musicais avaliados, ao ambiente de testagem e ao tipo de resposta indicada para a finalidade do BATUTA foram amplamente investigadas, com o propósito de lhe conferir fidedignidade. RESULTADOS: Os índices de Validação de Conteúdo (IVC) e de concordância entre os especialistas, quando analisados juntamente com as recomendações do comitê, resultaram em correções e em novas gravações dos áudios para garantir o cumprimento do teste. Os escores da aplicação do teste piloto indicaram boa consistência interna e o reteste confirmou a confiabilidade do BATUTA. CONCLUSÃO: Os resultados demonstraram a viabilidade do BATUTA para avaliar a percepção musical de pessoas com deficiência auditiva usuárias de AASI.

RESUMEN

PURPOSE: To analyze the performance of students aged between in an auditory skills screening software program, considering the influence of biological determinants and the correlation of auditory tasks with the behavioral assessment tests of central auditory processing (PAC), as well as to present the cutoff points of the battery. METHODS: In the first stage, the sample consisted of 96 students with typical development, who underwent hearing screening at school. A self-perception questionnaire and the auditory tasks of sound localization (SL), temporal resolution (TR), temporal ordering of frequency (OT-F) and duration (OT-D), auditory closure (AC), dichotic digit- binaural integration (DD) and figure-ground (FG) were applied. Of these, 66 children participated in the second stage of the study, including basic and behavioral audiological assessment from PAC. RESULTS: The gender variable influenced the DD task to the right ear. Age influenced the outcome of five auditory tasks. The right ear performed better in the DD and OT-F tasks. At the age between 6 and 7 years, there was a correlation between screening and diagnosis in the tasks of AC, TR, DD, FG, and OT-F. At the age of 8 years, there was a correlation in the DD and OT-F tasks. The pass/fail criteria varied according to the task and biological determinants. CONCLUSION: There was a correlation between screening and diagnosis in a greater number of tasks in the age group between 6 and 7 years. The cut-off points for the auditory tasks should be analyzed according to age, sex and/or ear side.

RESUMEN

PURPOSE: To develop an assessment script to observe hearing and central auditory processing in preschool children. METHODS: To The script was prepared based on a search in the Scielo databases and in the library of a university in the state of São Paulo using the following keywords: "central auditory processing", "hearing and language", "auditory processing disorders", "auditory processing in preschool children", and "vocabulary assessment", resulting in the selection of fourteen articles and two books. Then, questions related to auditory development and a script for assessing central auditory processing were prepared. RESULTS: The script consists of eight parts, namely: Identification and Anamnesis, Information about Mother and Pregnancy, Complaints, Auditory Development, Language Development, Motor Development, Simplified Auditory Processing Evaluation and Behavioral Audiological Assessment. CONCLUSION: The script is essential, given the lack of screening instruments in the literature for central auditory processing in preschool children that thoroughly investigate the entire process that permeates the auditory and language development of children aged 43 to 47 months.

RESUMEN

Sound synthesis refers to the creation of original acoustic signals with broad applications in artistic innovation, such as music creation for games and videos. Nonetheless, machine learning architectures face numerous challenges when learning musical structures from arbitrary corpora. This issue involves adapting patterns borrowed from other contexts to a concrete composition objective. Using Labeled Correlation Alignment (LCA), we propose an approach to sonify neural responses to affective music-listening data, identifying the brain features that are most congruent with the simultaneously extracted auditory features. For dealing with inter/intra-subject variability, a combination of Phase Locking Value and Gaussian Functional Connectivity is employed. The proposed two-step LCA approach embraces a separate coupling stage of input features to a set of emotion label sets using Centered Kernel Alignment. This step is followed by canonical correlation analysis to select multimodal representations with higher relationships. LCA enables physiological explanation by adding a backward transformation to estimate the matching contribution of each extracted brain neural feature set. Correlation estimates and partition quality represent performance measures. The evaluation uses a Vector Quantized Variational AutoEncoder to create an acoustic envelope from the tested Affective Music-Listening database. Validation results demonstrate the ability of the developed LCA approach to generate low-level music based on neural activity elicited by emotions while maintaining the ability to distinguish between the acoustic outputs.
