In-the-ear hearing aid with directional microphone system |
摘要 |
Apparatus for use as an in-the-ear hearing aid. The apparatus includes a housing having a shell and a face plate, wherein the shell is molded to custom fit a hearing aid wearer's ear. A first non-directional microphone system is included having a first output signal representative of the sound received. A second non-directional microphone system is included having a second output signal representative of the sound received. A switch mechanism is included having an operator extending through the housing for switching the in-the-ear hearing aid between a non-directional mode and a directional mode. In the directional mode, the microphone system is adjustable to account for component tolerances. The switched directional/non directional microphone feature is employed in a custom in-the-ear Contralateral Routing of Signals (CROS) or Bilateral Routing of Signals (BiCROS) two instrument hearing aid system.
