  • Wind-shielded acoustic sensor
    Patent number: 7916887
    Abstract: A wind-shielded acoustic sensor, having a microphone and a housing of the microphone. The housing has a streamlined, continuous profile about a latitudinal axis and a longitudinal axis thereof, such that wind-induced noise can be reduced. A plurality of uniformly spaced sound ports are formed along a plurality of circumferences centered about a longitudinal axis thereof. At least one region of the housing is sufficiently thin and pliable such that deformation will occur while subjected to wind. Thereby, both acoustic signals and wind-related random-like pressure fluctuations are transmitted into the cavity enclosed by the housing.
