Abstract: A wearable audio device, such as a hearing aid is provided. The wearable audio device includes a BTE microphone, a front-of-ear microphone, an adaptive filter, a subtractor circuit, and an acoustic transducer. The BTE microphone generates a BTE microphone signal. The BTE microphone may be arranged behind an ear of a user. The front-of-ear microphone generates a front-of-ear microphone signal. The front-of-ear microphone may be arranged within an ear canal or a concha of the ear of the user. The adaptive filter generates an adapted signal based on the BTE microphone signal and an error signal. The subtractor circuit generates the error signal based on the adapted signal and the front-of-ear microphone signal. The acoustic transducer generates audio based on the adapted signal. In some examples, the wearable audio device includes a plurality of BTE microphones configured as a directional microphone array.
