Five different windscreens were used to measure noise reduction, and the windscreen covered the microphone. They have different shapes, sizes, and pores per inch. First, the capability of each windscreen to block wind was studied, and then the effects of noise source, source magnitude, and wind speed on noise reduction, due to a windscreen, were investigated. The measured noise levels were examined in the 1/3 octave band. In the low frequency range (<50Hz), noise levels were severely distorted for all windscreens. In the high frequency range (>6300Hz), the largest windscreen showed more noise reduction than the other windscreens. In addition, an on-site experiment confirmed that noise measurement was possible for wind speeds up to 5m/s.
