摘要
在高温、高湿、高气流、高洁净度的工业厂房的降噪工程中 ,吸声材料的应用仍受到一定的限制。为了寻找一种适用于这类厂房的吸声材料 ,开展了对微穿孔金属板吸声体的研究。试验在混响室中进行。结果表明 ,此类吸声体具有较好的吸声性能。
Absorbing materials' uses have limitations in some respects of noise reduction projects in factory building where there are high temperature, damp, very fast airflow and cleanliness. The aim of the study was to quest for an appropriate absorbing material for these factory buildings. Metal microperforated absorber was studied and tested in the reverberation room. Results indicated that the kind of absorber's absorption properties were very well. It provides a scientific foundation for its use in noise reduction projects of factory buildings.
