Abstract:
A wind protection device for a microphone, the wind protection device including a body portion having a raised surface, a lower surface and a front face. The raised surface has a flow separation edge. The lower surface is offset from the raised surface the front face is bordered at a first edge by the flow separation edge and bordered at a second edge by the lower surface. The lower surface includes a recessed microphone holding area. Airflow separates from one of the raised surface or the flow separation edge, and the separated airflow is directed as one of recirculating airflow or a major airflow. The recirculating airflow is directed into a recirculation zone, and the major airflow is directed over a microphone zone and the recirculation zone to reduce the level of pressure fluctuations experienced by the microphone located in the recessed microphone holding area.
