DPOAE Characteristics
Prevalence: > 90% of all the tested ears.
Amplitude: Depends on the level and frequency of the primaries and the Fratio .
Latency: Depends on the stimulus level. It is postulated that there are two distinct mechanisms for the DP generation.
Superposition : Within an individual ear the SOAEs, TEOAEs and SFOAEs influence the DPOAE amplitude.
