  • SYSTEM AND METHOD FOR EVALUATING AN EAR SEAL USING NORMALIZATION
    Publication number: 20210400410
    Abstract: A system for evaluating an ear seal between an earphone of a hearing device and an ear canal includes a first transducer that plays sound in response to an electrical signal that includes a reference frequency component and a test frequency component lower than the reference frequency. A second transducer receives the sound in the ear canal. A controller is configured to: calculate at least one electrical signal level difference between the electrical signal reference and test frequency components, measure acoustical levels of the reference and test frequency components of the sound in the ear canal, calculate an acoustical signal level difference between the measured acoustical levels of the reference and test frequency components, calculate a normalized acoustical difference value by subtracting the electrical signal level difference from the acoustical signal level difference, and determine a measurement of the ear seal based on the normalized acoustical difference value.
