[Comparative study between auditory steady-state responses, auditory brain-stem responses and liminar tonal audiometry].

Objectives: Auditory steady-state responses (ASSR) using frequencies of modulation between 70-110 Hz are a new auditive exploration technique. The aim of the study was to evaluate the contribution of the ASSR to diagnostic of the audition.

Material And Method: Different aportations of auditory steady-states responses (ASSR) and auditory brain-stem responses (ABR) to diagnostic of threshold of audition were studied Differences between these thresholds and thresholds obtained by liminar tonal audiometry (LTA) were studied too.
