楼板隔声材料的撞击声隔声实验室测量结果研究

Study on the laboratory measurement results of impact sound insulation of floor sound insulation materials

隔声降噪问题越来越成为住宅品质的关注方向,尤其是上下楼层之间的撞击声隔声,隔声地板、隔声砂浆、隔声涂料及隔声垫等隔音材料应运而生。本文对比了这4种产品的计权撞击声压级和计权撞击声压级改善量的实验室测试结果。结果表明,这4种隔音材料的隔声效果、隔声原理和施工要求各有特点,在一定厚度、一定密度下均能改善基础分户楼板的计权撞击声压级,并达到标准要求。

The issue of sound insulation and noise reduction has become a focus of residential quality,especially the impact sound insulation between upper and lower floors.Sound insulation materials such as sound insulation floors,sound insulation mortar,sound insulation coatings,and sound insulation pads have emerged.This paper compares the laboratory test results of the weighted impact sound pressure level and the improvement of these four products.The results show that the sound insulation effects,sound insulation principles,and construction requirements of these four products have their own characteristics,and they can improve the weighted impact sound pressure level of the basic floor slab and meet the standard requirements under a certain thickness and density.
