Close range sounds, wind, and fast movements of the microphone boom, all may cause interfering noises. The Neumann WS 87 windscreen filters out these extraneous noises. For use with Neumann U67, U87, TLM103, TLM50, M147 Tube and TLM170 mics.
Typically, they 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.
Wind noise attenuation 26 dB. Attenuation at 15 kHz 3 dB.Diameter 90 mm. Color black.
