| 20080212819 | LOW NOISE MICROPHONE FOR USE IN WINDY ENVIRONMENTS AND/OR IN THE PRESENCE OF ENGINE NOISE - A microphone for use in windy environments. The microphone uses a transducer to flood the environment outside the microphone with a high frequency (such as an ultrasonic) acoustic field. The sounds desired to be detected are mixed with the high frequency carrier, and can then be received by the microphone with less wind noise. The microphone then demodulates the desired sound signals from the high frequency carrier. The microphone can be configured in a special emitter-receiver configuration that also reduces interference from engine noise. | 09-04-2008 |

The wind shield member is positioned such that in the course of normal use, wind directed toward the microphone will be intercepted and deflected by the wind-shield element. Deflecting wind away from the noise-cancelling microphone allows the microphone to produce a high-quality signal in spite of heavy winds. Various embodiments may also include a cover made of noise-damping material and/or holes through at least one face of the housing such that sound may pass through and reach the interior where the microphones are located. | 03-18-2010 |
