Auditory brain stem responses evoked with click stimuli of varying repetition rates (11, 31, 51, and 91 clicks/sec) and intensities but judged as being equally loud as three reference loudness levels (90, 80, and 70 phons) were examined in normal-hearing listeners. Analysis of wave component latencies and amplitudes indicated that loudness level changes are reflected in the brain stem response. However, the combined influence of stimulus rate and intensity was greater than that of perceived loudness level. It was concluded that the auditory brain stem response does not provide a direct link to loudness perception.
