20 Claims

1. A method, comprising:

performing occlusion cancellation in an ear-wearable device using an adaptive occlusion cancellation filter;

using an adaptive gain of the adaptive occlusion cancellation filter to determine a leakage path estimate between an external source and an eardrum of a user through the ear-wearable device;

using the leakage path estimate to update an adaptive hear-through filter of the ear-wearable device; and

using the updated adaptive hear-through filter for hear-through processing in the ear-wearable device.
