Abstract:

We develop a mathematical model of the ear s response to intense sounds over 120 dB that starts with pressure in the freefield, accounts for the effects of the head, external ear, middle ear, and cochlea, and ends with predictions of basilar membrane motion. The model s structure parallels the ear s anatomy and function and fits hearing loss data for weapons impulses that are not explainable by any other mechanism. The model suggests that upward movements of the basilar membrane produce the stresses that are the primary cause of damage.
