地板重量撞击声隔声特性的研究

Study on Characteristics of Heavy Impact Sound Insulation for the Floors

采用小型隔声箱体对几种地板的重量撞击声隔声特性进行研究的结果显示 :各种地板的重量撞击声频谱特性都十分相似 ,但木龙骨铺装方式下与实铺方式下的楼板重量撞击声频谱特性显著不同。各种地板的重量撞击声隔声性能表现不是很佳。

Characteristics of heavy impact sound insulation for the floors were studied through adopting small size sound insolation instrument.The results showed that frequency spectra property of heavy impact sound insulation were very similar among all the floors,but significantly different between solid flooring and flooring with wood keel.The floor were not effective on heavy impact sound.The performance of heavy impact sound insulation for the floor was also better under solid flooring than under flooring with wood keel.
