Abstract
An equalized hearing aid system includes a microphone, a first equalizer, a first mixer, and a first speaker coupled in series forming a first signal path with a second mixer coupled to the first equalizer within the first signal path. The microphone, a second equalizer, a third mixer, and a second speaker are coupled in series forming a second signal path with a fourth mixer coupled to the second equalizer within the second signal path. A control interface may be coupled to at least one of the first equalizer and the second equalizer. A Bluetooth module may be coupled to at least one of the first equalizer and the second equalizer. A third equalizer may be coupled to input signal into the first signal path and a fourth equalizer may be coupled to input signal into the second signal path.
