The Dependence of the Distortion Product 2f1-f2 on Primary Levels in Non-Impaired Human Ears.
Peer reviewed Peer reviewed
Dahr, Sumit; Long, Glenis R.; Culpepper, N. Brandt – Journal of Speech, Language, and Hearing Research, 1998
The ILO92 was used to determine the level of Distortion Product Otoacoustic Emissions (DPOAEs) at 2f1-f2 for 16 combinations of primary levels in the range of 40 to 80 dB SPL from 40 unimpaired adult ears. An overall increase of DPOAE amplitude with increase in primary level was observed. (Author/CR)

Transient-Evoked Otoacoustic Emissions as a Measure of Noise-Induced Threshold Shift.
Peer reviewed Peer reviewed
Marshall, Lynne; Heller, Laurie M. – Journal of Speech, Language, and Hearing Research, 1998
Otoacoustic emissions and behavioral hearing thresholds were measured in 14 participants before and after exposure to a 10-minute 105-dB SPL, half-octave band of noise centered at 1.414kHz. Results showed that the maximum temporary emissions shifts were half to one octave above the exposed frequency. Other findings are discussed. (Author/CR)
