摘要

针对低温环境对船舶多孔舾装材料声学性能的影响，阻抗管吸/隔声性能测试研究是被开展。基于传递函数法进行不同环境影响下玻璃棉材料的声学性能测试，实验给出了温度和含水率对玻璃棉材料声学性能的影响规律；在此基础上，以内河破冰船为例分析了低温环境下玻璃棉材料声学性能变化对舱室噪声的影响。研究表明，低温环境下玻璃棉的高频吸声系数将随含水率增加而显著下降，插入损失随含水率增加而增加，但低温环境导致玻璃棉材料声学性能的变化不会提高舱室噪声的超标风险。

Abstract

For the influence of a low-temperature environment on the acoustic properties of porous outfitting materials, the acoustic characteristic parameters test of the impedance tube is carried out. Based on the transfer function method, the study carries out the different environmental factors that influence ship outfitting material acoustic performance test study. The law of the influence of temperature and moisture content on the acoustic properties of glass wool material is given. On this basis, the port icebreaker as an example to analyze the effect of the low-temperature acoustic performance of glass wool material on the cabin noise. The study shows that the high-frequency sound absorption coefficient of wet glass wool at low temperatures will decrease significantly with increasing moisture content, and the insertion loss will increase with increasing moisture content. However, the changes in the acoustic properties of porous outfitting materials resulting in the polar environment do not innoise.
