1. A microphone for detecting sound and for reducing wind noise that interferes with the sound, comprising:

  • microphone circuitry for detecting the desired sounds;

    wherein the microphone circuitry comprises at least one transducer for generating a high frequency acoustic field, such that the high frequency acoustic field is mixed with the sound, thereby providing a mixed signal having a high frequency acoustic carrier and the sound as sideband signals, and at least one reflector positioned relative to the emitter such that it reflects the high frequency acoustic field back to the transducer.
