Spontaneous otoacoustic emissions were evaluated in 36 female and 40 male subjects. In
agreement with the results of previous surveys, emissions were found to be more prevalent
in female subjects and there was a tendency for the male subjects to have fewer emissions
in their left ears. The digitization of five minute samples of ear canal signals, combined with
sophisticated data analysis, produced a substantial reduction in the emission detection
threshold. 588 emissions were detected in 72% of the subjects and 56% of the ears. Of the …
