  • Automated real speech hearing instrument adjustment system
    Patent number: 8917892
    Abstract: A method for adjusting a hearing instrument to reduce feedback by placing a hearing instrument having an adjustable frequency response in a wearer's ear, providing a probe microphone for measuring the sound pressure level inside the ear and a reference microphone for measuring the sound pressure level outside the ear, exposing the ear to a stimulus and a dynamic event, determining the gain as a function of frequency from the difference in sound pressure level measured by the probe microphone and the reference microphone, identifying a feedback peak where the frequency is in the center of a range of frequencies and corresponds to the maximum gain in that range of frequencies and adjusting the hearing instrument to reduce the gain at a frequency corresponding to the frequency of the feedback peak.
