Abstract
An ear-worn hearing device includes a speaker disposed in a housing comprising a portion configured for wear over, on, or at least partially in a canal of a user's ear. Microphones are integrated with the housing, and a digital signal processing chain is coupled to and located between the microphones and the speaker. The digital signal processing chain includes active noise cancellation (ANC) circuitry configured to generate an anti-noise signal, and speaker-performance-enhancement circuitry coupled to the ANC circuitry and configured to generate a signal based on the anti-noise signal for the speaker. The digital signal processing chain is configured to communicate audio signals between the ANC circuitry and the speaker-performance-enhancement circuitry without changing a format of the audio signals.
