Abstract

This disclosure relates to a method and apparatus for diagnosing operation errors in hearing assistance devices, including but not limited to hearing aids. The hearing assistance device includes a microphone and a receiver. In various approaches, a housing is configured to hold the hearing assistance device and to provide a controlled acoustic environment between the microphone and receiver. A lid is configured to cover an opening in the housing to seal the housing from external sounds, in various approaches. In some examples, the hearing assistance device is configured to detect placement of the lid on the housing from within the housing and, once placement is detected, output acoustic signals through the receiver and compare resulting microphone input to baseline parameters to diagnose calibration errors.
