1. A method, comprising:
initiating, with first and second hearing devices present in a charging case, a self-check protocol by at least one of the first and second hearing devices, the self-check protocol comprising:
wirelessly coupling the first and second hearing devices;
activating a first microphone of the first hearing device and generating an acoustic test stimulus by a second acoustic transducer of the second hearing device;
assessing performance of the first microphone in response to the acoustic test stimulus by:
comparing a response of the first microphone to a pre-established profile representative of nominal microphone performance; and
detecting sub-optimal performance of the first microphone in response to measuring a specified deviation from the pre-established profile;
activating a second microphone of the second hearing device and generating an acoustic test stimulus by a first acoustic transducer of the first hearing device;
assessing performance of the second microphone in response to the acoustic test stimulus by:
comparing a response of the second microphone to the pre-established profile; and
detecting sub-optimal performance of the second microphone in response to measuring a specified deviation from the pre-established profile; and
storing results of the performance assessment in a memory;
wherein the self-check protocol is repeated over time, and the method further comprises:
tracking changes in performance of the first and second microphones over time; and
determining or predicting when performance of the first or second microphone becomes sub-optimal using the tracked performance changes.
