摘要
低频噪声在社会生活噪声中所占比例日益增大,其影响受到人们广泛的关注进而遭到投诉。通过对许多产生低频噪声的设备进行频谱分析发现:这些设备,如水泵等,噪声明显呈低频特性;当我们用II型噪声测量仪测出的Leq值一般都能达标,但用I型设备对此进行频谱分析时,大多都超标,特别是夜晚超标比较严重。
It is more and more attendant by people that the low frequency noise is more in the social noise.It is found that those noise is presented the prominent low frequency speciality,such as water pump,when those equipments produced low frequency noise is analyzed;in generally,the Leq value can be reached standard measured by II type instruments,but it will be more over the standard measured by I type instruments analyzed on low frequency,specially in the night.
