Setting individualized acoustic coupling parameters of an audio device

Abstract

Disclosed herein, among other things, are systems and methods for setting acoustic coupling parameters for hearing devices. A method includes producing a receiver signal through a receiver of a hearing device, or a physical extension of the receiver, placed inside an ear canal of a user. A microphone signal is sensed, in response to the receiver signal. Based on the receiver signal and the microphone signal, an estimate of an acoustic coupling characteristic of the hearing device is computed. The estimate of the acoustic coupling characteristic may be compared to stored reference data from a memory or to a second estimate of the acoustic coupling characteristic computed for a second hearing device in a second ear of the user to obtain an improved estimate of the acoustic coupling characteristic. The improved estimate of the acoustic coupling characteristic is used to modify an operational characteristic of the hearing device.
