Abstract
An ear-worn hearing device with occlusion reduction is disclosed. The hearing device includes a signal processor configured to generate an anti-occlusion signal based on a feedforward signal from a vibration sensor located to detect tissue-propagated vibration within the user's at least partially occluded ear canal. Optionally, the anti-occlusion signal can also be based on a feedback signal from a microphone located to detect sound within the at least partially occluded ear canal. Unwanted vibrations detected by the vibration sensor can optionally be removed from the anti-occlusion signal based on filtering the anti-occlusion signal.
