Masking Audiometry With Self-Recording Audiometer: I. Normal hearing

Abstract

Results are reported in normally hearing listeners for the size of the threshold tracings in self-recording audiometry in quiet, and in 45, 65, 83 and 103 db (re 0.0002 microbar) white noise. It is shown that the excursions diminish a few decibels in size when the recording is made in the presence of higher noise levels. As both the testing tone and the noise suffer the same per-stimulatory loudness loss, the recorded tracings show no deterioration as a function of time.
