Introduction Auditory brainstem response using click stimuli enable global objective estimation of hearing threshold. Recently, it has been suggested that a chirp stimulus may produce a synchronous response from a large portion of basilar membrane. The chirp was designed to produce simultaneous displacement maxima along the cochlear partition by compensating for frequency-dependent traveling-time differences. Material and methods In this study, response characteristic of both click and chirp stimuli are compared in children. We compared latency and amplitude of wave V at different intensity levels and waves I and III at high level. Results and conclusion Results show that wave V on using chirp stimuli could be detected easier with shorted in latency and larger in amplitude than in click auditory brainstem response. However, click stimulus was better than chirp stimulus at high-intensity levels with respect to the identification of waves I and III.
