Evoked acoustic emissions in high-frequency vs. low/medium-frequency hearing loss.
Evoked otoacoustic emissions have been recorded from ears with high- and low/medium-frequency hearing losses using a simple technique with fixed stimulus intensity and no suppression of stimulus artifact. Ears with low/medium frequency hearing loss exceeding 40 dB HL generate responses ending before 17.5 ms after stimulus onset. This may be used for testing of low/medium frequency hearing in ears where BRA indicates normal or only slightly impaired high-frequency hearing. Interrelationships between various response parameters and hearing losses have not been demonstrated statistically.
