The Neumann WNS-110 is an acoustically transparent black foam windscreen for KM 80, KM 100, KM 180 and KM D microphones. It provides -21 dB wind noise attentuation, -1 dB @ 15 kHz. Close range sounds, wind, and fast movements of the microphone boom, all may cause interfering noises. To avoid these unwanted sounds a windscreen provides protection.
This windscreen is made out of open-cell polyurethane foam to avoid interfering resonances and does 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 12.4274 miles per hour (20 km/h), generated by a noiseless wind machine. Acoustically transparent wind and pop protection with improved efficiency.
