METHOD AND APPARATUS FOR DIRECTIONAL ACOUSTIC FITTING OF HEARING AIDS

摘要

A method of acoustically fitting a hearing aid comprises providing a plurality of audible tones, each having a predetermined frequency through stereo headphones. The tones are provided at specific sound pressure in each ear. The patient changes the relative sound pressure in each ear until a perceived direction of source of the tone is in front of the patient. The amplification or attenuation requirements of a hearing aid are modified based on the difference in the sound pressures required for the left and right ears of the patient for perceived directional sameness for each frequency band-pass channel.
