Technical Notes
Windscreen (WS-02)
During outdoor measurements or measurement of ventilation devices, wind noise can fal-
sify measurement results. To counter such problems, the supplied windscreen WS-02
should be mounted on the microphone. The characteristics of the WS-02 are shown be-
low. The attenuation of wind noise produced by the windscreen is about 25 dB for sound
pressure level (A weighting) and 15 dB for sound pressure level.
The influence of the windscreen WS-02 on the acoustic performance of the microphone is
within ± 1.0 dB up to 12.5 kHz, as shown in the diagram on the next page.
