摘要: 噪声污染是当今世界性重要的环境污染问题,严重危害人类健康,它的危害体现在干扰人类正常的工作、生活、学习和睡眠。然而对于噪声的关注,由于低频噪音(低于500 Hz)不易发觉,检测设备局限等原因,在近些年才得到重视,本文综述噪声对健康的影响,指出建议家电噪音标准应增加对低频噪音的测试,对噪声进行倍频程谱分析,采用NR曲线来衡量每个倍频带声压级是否在允许范围内,建议用C级声级方法测试低频噪音。

关键词: 低频噪音, 噪声检测, C级声级

Abstract: Noise pollution has been regarded the important influencing factors that harm health and environment by interrupting people’s life, work, study, rest and sleep directly and has become a common problem around the world. However, though the negative effect of noise is well known the low frequency noise has attracted attention in the recent years since it is not easy to sense and not easy to determine. This article has concluded the negative effect on health and recommended the specific standards on low frequency noise from household electrical appliances. To conduct octave spectrum analysis on the noise, and then to apply the NR curve to measure whether the sound pressure level of each octave band is within the allowable range. It is recommended to use the C-level sound level method to test low-frequency noise.

Key words: Low frequency noise, Noise measurement, Class C sound level
