  1. The reason that the noise is lower with inclining tongue is : 1 ) both the radius of the tongue and the gap between the tongue and the blade are changed across the wideth ; 2 ) the phase angle between blade and the tongue is changed across the wideth, therefore the peak value of the noise do not appear at the same time, so the peak value of the noise with inclining tongue is much lower than the straight one. the influence of the expanded angle of the shell of the fan on the noise was invested experimentally, and the optimal angle was got

    傾斜蝸舌降噪的主要原因是：一是改變了從氣流入口側到風機輪盤的蝸舌間隙和蝸舌半徑；二是改變了葉輪與蝸舌非定常相互作用的相位差，使其產生噪聲也有相位差，迭加的結果進一步降低了噪聲。另外，試驗研究了不同蝸殼擴張角對風機噪聲及效率的影響規律，蝸殼擴張角選擇當否，對效率和噪聲影響較大。
