摘要
通过对通风消声箱与双层窗户的整合研究,故针对装上消声箱后的通风隔声窗,探讨其传声损失频率特性与传统均值单层窗的差异。通过分别对安装0片、2片、4片消声片后通风隔声窗的传声损失频率特性,可知通风隔声窗隔声性能取决于消声片数,从0片提升至2片计权隔声量从21dB提升至32dB。4片消声片下通风隔声窗的计权隔声量值达34dB以上,具有良好的隔声性能。
Through the integration study of the ventilation muffler box and double-layer windows,the difference between the frequency characteristics of the sound transmission loss and the traditional average single-layer window is discussed for the ventilation sound-insulated window after the muffler box is installed.According to the frequency characteristics of the sound transmission loss of the ventilation sound insulation window after installing 0 pieces,2 pieces,and 4 pieces of silencers,it can be seen that the sound insulation performance of the ventilation sound insulation windows depends on the number of silencers,from 0 to 2 pieces.The weighted sound insulation has been increased from 21dB to 32dB.The weighted sound insulation value of the ventilation sound insulation window under the 4 pieces of muffler is more than 34dB,which has good sound insulation performance.
