Abstract

Within this research, testing of the acoustic properties of polyurethane foam samples was conducted. The measurement of the absorption coefficient was performed using the transfer function method in an impedance tube, according to the SRPS EN ISO 10534-2:2008 standard. The tested samples represent highly elastic polyurethane foam of low density, with sample thickness ranging from 10 mm to 100 mm. The research results indicate the potential application of polyurethane foam in areas that require efficient sound insulation or noise control, particularly in the mid-frequency range. Therefore, polyurethane foam can be considered an excellent material with acoustic properties that exceed expectations within the given frequency range.

高弹性聚氨酯泡沫蒸汽3744的声学特性
在本研究中,对聚氨酯泡沫试样的声学性能进行了测试。根据SRPS EN ISO 10534-2:2008标准,在阻抗管中使用传递函数法测量吸收系数。测试样品为低密度的高弹性聚氨酯泡沫,样品厚度从10毫米到100毫米不等。研究结果表明,聚氨酯泡沫塑料在需要有效隔声或噪声控制的领域,特别是在中频范围内具有潜在的应用前景。因此,聚氨酯泡沫可以被认为是一种优秀的材料,其声学性能在给定的频率范围内超出预期。
