Research on Wind Noise Estimation Method by Synchronous Measurement of Low Frequency Sound and Wind Speed

Abstract

It is generally known that low-frequency sound is affected by natural winds when measured on site. In this paper, the estimation method of wind noise by natural wind was examined by wind tunnel experiment and field experiment, and the preparation procedure of the estimation methods was presented. In the field experiment, two types of estimation formulas with different category of surface roughness were constructed, and the correlation between the field measured values and the estimated values was examined. As a result, it was confirmed that there was a strong correlation between measured values and estimated values.
