The Effects Of Ear Canal Pressure Variation On Distortion Product Otoacoustic Emissions, Jodi L. Head
Dissertations and Theses
The middle ear system is a vital component in the propagation mechanism of otoacoustic emissions. As such, investigation of the effect of variation in middle ear impedance on the measurement of emissions is warranted.
Distortion product otoacoustic emissions (DPOAEs) have gained recognition as a means of gaining frequency specific information on auditory function. As the effects of changes in middle ear impedance will vary as a function of frequency, a clear definition of the relationship between middle ear impedance and DPOAE amplitude across the frequency spectrum is needed.
Twenty adults (ages 20-37) with normal hearing and normal middle ear function …
