A system for recording evoked otoacoustic emissions (EOAE) was developed based on the signal processor normally used in auditory evoked potential measurements. With this system, click-evoked otoacoustic emissions with latencies between 5-10 ms were recorded from all the 59 normal-hearing ears tested. Although EOAE thresholds ranged from -5 to 25 dB SL, 3/4 of them was with 0-10 dB SL. Ten measurements at intervals of 1 week in 4 ears showed that EOAE was quite stable. Thus, the measurement of EOAE was considered of clinical significance as an objective, sensitive and quick hearing-screening test. Its prospect in clinical applications was also discussed.

D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
D001299	Audiometry	The testing of the acuity of the sense of hearing to determine the thresholds of the lowest intensity levels at which an individual can hear a set of tones. The frequencies between 125 and 8000 Hz are used to test air conduction thresholds and the frequencies between 250 and 4000 Hz are used to test bone conduction thresholds.	Audiometries
