The Suppressibility of Otoacoustic Emissions and Loudness by Low-Frequency Biasing Tones as a Function of Probe Level

As the observed iso-suppression rate is broadly consistent with the growth of basilar membrane vibration with increasing stimulus level in the active region of the traveling wave, we conclude that equal suppression of cochlear responses during partition biasing occurs when bias displacement grows in proportion to the probe's traveling wave amplitude in its active region.
