[Research on the high-frequency domain of transiently evoked otoacoustic emissions].
OBJECTIVE
To evaluate the clinical use of transiently evoked otoacoustic emissions (TEOAE) in patients with high-frequency sensorineural hearing loss, comparing the result of TEOAE with audiometry to find the correlation between them.


METHODS
Fourteen normal adults and 25 patients with high-frequency hearing-loss were measured with TEOAE25 analyzer system and OB822 audiometer respectively, to compare the changing trend of the two examinations.


RESULTS
In the domain of 1.5 to approximately 4.5 kHz, there was significant difference of TEOAE between normal cases and hearing-loss cases. The results of TEOAE and audiometry had correlation with each other. The changing trend of the two examinations was accordant.


CONCLUSIONS
Combined with pure tone audiometry, TEOAE could discover the degree and range of high-frequency hearing loss more correctly.
