Slow variations of the amplitude and frequency of spontaneous otoacoustic emissions.
Systematic, slow variations of the amplitude and frequency of spontaneous otoacoustic emissions in human ears, occurring over the first 20-30 min of recording, are described. Experimental observations suggest that these variations may arise from a centrally mediated, bilateral influence on the mechanics of the ear.
