The auditory steady-state response (ASSR) is commonly used in clinical pediatric audiology to provide an electrophysiological estimate of hearing thresholds, and has the potential to be used in unsupervised mobile EEG applications. Enhancement of the ASSR amplitude through optimization of the stimulation and recording methods shortens the required testing time or reduce the offset between the electrophysiological and behavioral thresholds. In this study, the spatial distribution of the ASSR to broadband chirp stimuli is investigated across a wide range of repetition rates on the scalp and in the ears. Moreover, the ASSR amplitude is compared for commonly used electrode configurations. read more
