Some Characteristics of the Peak Latency and Amplitude of the Acoustically Evoked Response

Abstract

This experiment explored some characteristics of peak latency and amplitude of the human evoked auditory response as functions of time and number of signals at two sensation levels (20 and 40 dB) in 10 subjects. As signal intensity increased, the number of responses elicited increased, the amplitude of the responses increased, and the latency of the first two components of the response decreased. The amplitudes and latencies of any component of the evoked response did not change significantly as a function of number of signals presented.
