摘要

In this paper, it is investigated that how vertical wind speed affects acoustic parametric array sound field by theoretical derivation and analysis. It is proved that sound pressure distribution of acoustic parametric array acoustic field by experiment test, and the influence on the sound pressure distribution under different wind speed is analyzed. Moreover, corresponding experiments have been done, and the results show that wind speed has no effect on basic sound pressure of sound wave, but will affect the spread direction of sound field. Vertical wind speed can make the sound pressure distribution curve in the cross-section perpendicular to the sound propagation direction move along the wind speed direction for a certain offset distance. The bigger the wind speed is, the greater the offset distance will be. It is significant in revealing the influence of wind speed on the acoustic field of parametric array.
