Patent abstract

A hearing instrument includes a first speaker having a first frequency range. The hearing instrument also includes a second speaker that is disposed in the ear of a listener. The second speaker has a second frequency range that is wider than the first frequency range. A microphone unit is coupled to the first speaker and the second speaker. The first speaker creates replacement sounds within the first frequency range that replicate sounds that are lost to the listener as a result of an occlusion effect at the second speaker. The replacement sounds are presented to the listener.
