System and method for self-calibrating audio listening devices
A self-calibration system may include a housing including a first calibration circuit configured to coordinate with a second calibration circuit to execute a calibration sequence for an active noise cancelling (ANC) earphone. The housing further includes a cavity configured to accommodate the ANC earphone, wherein the cavity is contoured to simulate the ANC earphone in a user's ear. The housing further includes a calibration microphone coupled with the first calibration circuit and configured to measure calibration sound waves from the ANC earphone, and a calibration speaker configured to emit calibration sound waves to the ANC earphone.
