Close range sounds, wind, and fast movements of the microphone boom, all may cause interfering noises. To avoid these unwanted sounds, use the Neumann WS87 windscreen on the appropriate Neumann microphone models.
Typically, windscreens are made out of open-cell polyurethane foam. These windscreens do not cause interfering resonances and do not influence the directional pattern. Only in the upper frequency range is the output level slightly attenuated. The wind noise attenuation was measured without electrical filtering in a turbulent air stream traveling at 20 km/h, generated by a noiseless wind machine.
Windscreen for U 67, U 87 (Ai), TLM 50, TLM 103, M 147 Tube and TLM 170 (R).
The WS87 windscreen suppresses wind noise approximately 26 dB. Attenuation at 15 kHz approx. 3 dB. Diameter is approximately 90 mm and the color is black.
