A novel method of estimation of otoacoustic emissions (DPOAE) in high frequency range and possible medical applications

Dietmar Hecker, Bernhard Schick, Carl Albert Bader & Wolfgang Delb
Distortion product otoacoustic emissions (DPOAE) are measured in clinical routine up to a frequency of 8 kHz. The intensity of the component at 2 f1–f2 is used as an indicator of cochlea status. Although high frequencies DPOAE have a high potential, they are not being used because of their poor[for full text, please go to the a.m. URL]
