摘    要:本文研究并实验了目前常用的四种装饰材料对吸声体吸声性能的影响,在同等表面积、等量相同的吸声材料、空腔体积依次增大、侧面边数增多的条件下,不同形状吸声体的吸声特性,以及吸声体底面面积,空腔体积和吸声系数的关系;研究并实验了声源是否固定,传声器带不带防风罩对测试结果的影响。

关 键 词:外装饰材料  玻璃棉  矿棉  吸声系数

Study on the Absorption Properties of Functional Absorber

Authors:Wen Xiaoning
Abstract:The effect of four kinds of usual decorative materials on absorption properties of absorber are tested and studied in this paper. The absorption properties of different forms of absorbers with varying hollow volume and number of side line are tested and studied,under the same absorption materials,equal area.The relations between the absorber bottom area,hollow volume and absorption coefficient are obtained.Finally,the effects on test results,of whether sound source is fixed or not and microphone boom is fixed with windproof cover or not,are tested and studied also.
Keywords:decorative material  glass wool  slag wool  absorption coefficient
