The effects of reversing the polarity of frequency-limited single-cycle stimuli on the human auditory brain stem response.

abstract：OBJECTIVES:The level-dependent growth of distortion product otoacoustic emissions (DPOAEs) provides an indirect metric of cochlear compressive nonlinearity. Recent evidence suggests that aging reduces nonlinear distortion emissions more than those associated with linear reflection. Therefore, in this study, we generate...
