本文基于声学振动理论与实验分析技术，系统地研究了金属锯切过程减振降噪的有效途径，取得了令人注意的实际降噪效果。金属锯切降噪量达１２ｄＢ（Ａ）以上。
Based on the theory of acoustic vibration and experimental analysis, this paper systematically studies the effective way of vibration reduction and noise reduction in the metal sawing process, and achieves remarkable practical noise reduction effect. Metal cutting noise reduction of 12dB (A) above.
