MICROPHONE WINDSCREENS / WINDSHIELDS 

Microphone Windscreen (also known as microphone windshield and mic sock) by Brüel & Kjær  is designed with specially prepared, open-pored, polyurethane foam capable of attenuating wind noise 10 to 12 dB, depending on wind speed. The mic windscreens effectively reduces excessive pressure on a microphone facing winds, providing the ideal measurement conditions for environmental noise logging, and all other outdoor microphone measurement tasks.
