Embodiment Construction
[0038]FIG. 2 shows a schematic diagram of the operational environment according to the present invention. A remote sound sensing apparatus 200 generates an outgoing coherent electromagnetic waves beam 220 that is pointed directly on a vibrations generating sound source 210. Upon hitting the vibrations generating sound source 210, the outgoing coherent electromagnetic waves beam 220 is reflected and returns, with modified physical properties, as a reflected coherent electromagnetic waves beam 230, to the remote sound sensing apparatus 200. When directing the beam at the sound producing source the vast majority of the detected vibrations are related to the sound source. Since the vast majority of the sound producing vibrations related to a sound source are detected, a high degree of separation between the sound source and the ambient is thus achieved. This is due to the fact that the beam is pointed directly at the vibrations producing sound source.
