1.
A model of sound absorption coefficient based on damped harmonic oscillator and its application
基于阻尼谐振子的吸声系数模型及其应用
2.
The sound absorption coefficient of the material was tested by standing wave tube method.
采用驻波管法测试材料的吸声系数。
3.
The effect of thickness and density of the melamine foam on the sound absorption coefficient was analyzed by impedance experiment.
结果表明:材料厚度对其吸声性能的影响较大,密度对吸声性能只在频率400 Hz以下略有影响;三聚氰胺泡沫塑料较纤维材料低频(<1 kHz)吸声系数低,中高频(≥1 kHz)系数高;与聚氨酯泡沫塑料相比,低频(<1 kHz)吸声性能相当,中高频(≥1 kHz)吸声性能较佳。
