RESUMEN
234 dentists and dental nurses were examined with a normal and a high-frequency audiometer in high standard clinical conditions. Their ordinary and high-frequency hearing as compared with the controls showed no significant differences. Thus, exposure to high-frequency noise from high-speed drills and other modern dental instrumentation does not appear to be harmful to one's hearing and does not necessitate audiologic screening procedures for dental personnel.

An unlimited, portable, text-to-speech synthesizer, Synte 2, is introduced. Since 1977, it has been applied and tested to the rehabilitation of the deaf and others unable to speak as well as to the rehabilitation of the blind. It has been shown to be beneficial to those people. With this system, it seems possible to markedly increase the concept capacity of the deaf. In audiology, it provides a new way to produce objective, everlasting, and ever-repeatable ordinary and sensitized speech tests. Further, the apparatus has innumerable applications in audiological and speech pathological research. This kind of speech synthesizer has come to stay in clinical use. General principles of the use of the synthesizer and experiences over 3 years in rehabilitation and medical research are discussed.
