Measurement microphones on sound level meters must be protected from the effects of wind blowing across the diaphragm.

The CEL foam windscreens are specifically designed to minimize any interference caused by air turbulence around the microphone capsule. Always use the correct size foam windscreen to suit the diameter of the microphone.

Technical Information

The CEL foam windscreens are manufactured from an open cell material that offers protection to the microphone capsule when used in dusty environments indoors or in windy or gusty environments out of doors. The windscreens can reduce the interference caused by wind blowing across the microphone by approximately 15 dB and should always be used for external noise measurements. Foam windscreens are not recommended by the manufacturer for long-term measurements as they can become water-logged in prolonged rainfall situations. It is not recommended to make noise measurements when wind speeds exceed 25 mph due to the possibility of errors in the readings caused by wind blowing over the microphone and windscreen.
