摘要

针对目前国内木基静音地板尚无相关测试标准的问题,本试验利用钢球自由下落撞击法,对地板的静音性能进行了测量和评价。试验证明:钢球自由下落撞击法对不同静音性能的地板可以给出精确的定量评价。为今后木基静音地板测试方法标准的起草和制定,提供了新的思路。

Abstract

Soundproof wood-based flooring is a new product developed for acoustic noise reduction. Currently,there is no standard available for evaluating the acoustic performance of wood-based flooring. The authors developed a test method for dropping a free falling steel ball from a specified height and impacting the flooring to simulate people walking on flooring. The acoustic signal of the impact was collected and analyzed as an index to describe the acoustic performance. Different steel balls hitting various floorings,including solid flooring,laminate flooring,parquet flooring and cork flooring,were performed. The results showed that this method was feasible and further study was needed.
