This study investigated the relation of peak amplitude and latency to signal intensity for the brainstem auditory evoked response (BSAER). One thousand clicks were presented to obtain each averaged response. Responses were obtained to clicks presented at sensation levels of 15, 20, 30, 40, 50, 60, and 70 dB. Five adult males who demonstrated normal hearing served as subjects. Latency and amplitude for various wavelets were plotted against signal intensity. A consistent trend of decreased peak latency occurred with increased signal intensity. Contrary to previous reports, the amplitude of Wavelet V showed a linear growth with increased signal intensity.
