摘　　要：为研究装甲车辆舱室噪声特性,测量并分析了某型装甲车辆各个工况下舱室不同测点的噪声情况。结果表明:装甲车辆运行时,舱室噪声以低频成分为主且强度较高,超出了相关标准规定限值;变速行驶工况下,舱室噪声波动性较大,噪声污染级偏高,超出了听力保护的卫生范围。研究结果可为相关评估工作提供参考,也表明现用装甲车辆舱室噪声测试与评价标准有待完善。To explore the cabin noise characteristics of armored vehicle comprehensively, the cabin noise of a certain kind of armored vehicles at different test point under different working conditions is measured and analyzed. The results show that： the cabin noise of running armored vehicle is high in intensity and mainly low-frequency, exceeding the standard limits; when the vehicle moves with non-uniform velocity, the cabin noise is volatile, and the noise pollution level is high, overrunning the noise limit of hearing protection. However, the testing and evaluation standard presently used by our military needs to be improved. The research can provide reference for relevant assessment work.
