"Study on Acoustic Absorption Frequency Characteristics of Polyurethane Foam Materials"
Pages: 84-87,6
Year: Issue:  5
Journal: Polyurethane

Keyword:  聚氨酯泡沫吸声材料吸声结构;
Abstract: Polyurethane foam materials are widely used as porous acoustic absorption materials. The sound absorption performance involves in properties of cell structures, sound- absorptive structures and the actual setting state. This article mainly discusses development of acoustic absorption frequency identity of polyurethane foam and its sound-absorptive structure panels.
