• The former one is a product of the pressure pulsation resulting from the fan blade periodically cutting the air , with the blade passing frequency as its base frequency and accompanied by higher harmonics . the wide - band turbulent noise is formed when the rotating fan forces the surrounding air to produce turbulent throw - outs and results in gas thickening and thinning processes
  旋转噪声是由于风扇的叶片周期性地切割空气，引起空气的压力脉动产生的，以叶片通过频率为基频，并伴有高次谐波。湍流噪声是由于风扇运动导致的周围空气发生湍流脱体，使空气发生扰动，形成气体的压缩与稀疏过程而形成的，是一个宽频带噪声。
