title: Reflection of bounce phenomenon in DPOAE: a human study.
abstract: The behavior of distortion product otoacoustic emission, DPOAE, has been studied in normally hearing subjects after application of a tone of 0.25-kHz frequency and of 80-dB nHL intensity during 3 min. The bounce phenomenon has correspondingly been investigated just in humans and just via the objective approach. The reliable augmentation of DPOAEs was observed at 0.5 min after the cessation of exposures, the amount of increments being statistically equal at different DPOAE frequencies, 0.75, 1, 1.5, and 2 kHz. At 2 and 4 min after the exposure, in contrast, DPOAE magnitudes were shown to be similar to those of pre-exposure recordings. The present DPOAE results were matched with the previous data on transiently evoked otoacoustic emission and no principal differences have been found between.
