Apparatus and method for determination of an audibility range

摘要

The device has a personal computer (PC) (6) to read a measured sound pressure level from a hearing aid. A residual volume in an auditory canal of a patient determines the sound pressure level in front of an eardrum. An adjustment software of the PC calculates the level at the eardrum from the measured pressure for determining a masking threshold. A lower limit of an established hearing range is displayed graphically on the PC. An independent claim is also included for a method for determining a hearing range of a patient.
