restricts total peak-to-peak displacement of the stapes. Previous studies have suggested that
for moderate (< 130 dB SPL) sound levels intracochlear pressure (P IC), measured at the
base of the cochlea far from the basilar membrane, increases directly proportionally with
stapes displacement (D Stap), thus a current model of impulse noise exposure (the Auditory
Hazard Assessment Algorithm for Humans, or AHAAH) predicts that peak P IC will vary …
