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: 24dB
Attenuation at 15 kHz: approx. 2dB
