摘要

为了考察软木聚结材料自身及其贴覆于3种人造板基材后的吸声性能,探究将其用于减少室内环境噪音的可行性,采用驻波管法测定其吸声系数。结果表明:在一定范围内,软木聚结材料吸声系数与其厚度成正比,与密度成反比;在人造板基材正面贴覆软木聚结材料,其吸声效果优于基材背面贴覆。可依据实际应用需要,选择合适的贴面方式、材料密度和厚度。

Abstract

In order to evaluate the performance of agglomerated cork boards for indoor sound barriers,the sound absorption coefficients of the panels laminated,with different agglomerated cork boards,were measured by the standing wave tube method.The results showed that the sound absorption coefficient of the samples increased with increased thickness or decreased density.
