SYSTEM AND METHOD FOR CALIBRATING AND DETERMINING HEARING STATUS

摘要

Method and System for characterizing an incident pressure wave in a hearing test. The method includes introducing a sound signal of a predetermined frequency and amplitude into an ear canal, measuring at least a sound pressure level (P_m) in the ear canal, processing information associated with the sound pressure level, obtaining at least an acoustic reflectance (R) based on information associated with the sound pressure level, and determining an incident wave pressure parameter (P₊) in the ear canal according to the following formula: P₊ = P_m/1+R.
