Abstract: The auditory brainstem response (ABR) is a gold standard test for objectively estimating hearing thresholds due to its high sensitivity and specificity. The time taken to record frequency-specific ABRs using the conventional single-frequency monaural approach is typically 45-60 minutes. Methods previously used to reduce testing time using increased rate, or chained stimuli have not been popular in clinical settings due to additional hardware and software requirements. We propose a multifrequency chained stimuli approach which presents several stimuli of different frequency to the two ears in an interleaved manner to maximize acquisition efficiency, significantly reduce test time, and minimize response adaptation. This paradigm can be easily generated in most commercial ABR systems currently used in clinics. Our novel method and stimuli together create a recording paradigm that can yield robust and lower binaural ABR thresholds, resulting in a quick and effective clinical tool. This presentation will discuss data recorded from 30 normal hearing young adults will be presented. The ongoing implementation of automatic peak detection will also be discussed during the presentation.
