1. A microphone system comprising:

  • a microphone element to output a microphone output signal;

    a touch sensor disposed on or within proximity of an outward facing surface of a microphone system housing, the touch sensor arranged to detect a proximity or a contact with a user skin surface of a user finger;

    a touch sensor circuit coupled to the touch sensor configured to receive signals from the touch sensor and determine whether the touch sensor is touching the user skin surface of the user finger; and

    a processor adapted to process the microphone output signal using a modified signal processing responsive to a determination the touch sensor is touching the user skin surface of the user finger for a duration of the determination the touch sensor is touching the user skin surface and adapted to return to a normal mode signal processing following a termination of the determination the touch sensor is touching the user skin surface.
