• OS2-6 Study on Acoustic Noise Characteristics of Micro Wind Turbine System Installed in Dwelling Environment

抄録

A micro wind turbine with rated power of 400W has been examined about its acoustic noise characteristics, experimentally. The turbine was installed at the rooftop of the building and the noise measurements and data analyses were conducted in accordance with the standard of IEC 61400-11. The sound pressure level increases with wind speed in the turbine operating condition, whereas the level of background noise is remained approximately constant irrespective of the wind speed. Therefore, it was confirmed that the acoustic noise characteristics of the wind turbine depend on the inflow velocity. The frequency analysis indicates dominancy of the high frequency component due to the turbulent flow noise in comparison with the low frequency band such as the blade passing frequency. Slight directivity of the acoustic emission has been observed in the horizontal plane and the largest noise is emitted in the downstream.
