抄録

Influence of the wind on A-weighted sound pressure level and sound pressure level were investigated for the noise, which consisted primarily of road traffic noise, and the white noise from a loudspeaker. Sound pressure levels became larger with increasing wind speed, and we obtained the same results as the previous studies. We showed that the A-weighted sound pressure levels changed with relationships between both sound pressure levels of wind noise and the measured noise, as well as those of the frequency spectrums. Then, we presented that the measured noise was masked by the wind noise, as the measured noise were smaller.
