Figure 2.

Sample plots of wideband reflex growth obtained from a single ear. Left: The acoustic stapedius reflex absorbed power (delta WL) level shift across frequency at all activator levels: 1 (35 dB SPL) through 10 (80 dB SPL). The magnitude of the absorbed power shift grows with increasing activator level. Right: acoustic reflex growth function for the reflex response. The dotted line indicates the minimum cumulative absorbed power shift of 0.7 dB that the response must reach in order to be classified as a reflex. The acoustic reflex threshold (ART) for this ear is marked at 45 dB SPL.
