RESUMEN

This study aims to find an effective chirp signal that enhances the amplitude of wave-I of auditory brainstem response (ABR) to diagnose "cochlear synaptopathy." Although several chirp signals have been proposed to enhance the amplitude of wave-V, the effect on wave-I has not been clarified yet. Ten chirp signals, which have shorter group delays than the commonly used "CE-chirp," were produced to measure the amplitudes of wave-I and wave-V of the ABRs. The results show that one of the chirp signals significantly enhanced the amplitude of wave-I, where the group delay is approximately half of the CE-chirp.
