Acoustics—Frequency-weighting characteristic for infrasound measurements


Standard in brief
Scope of Application:  
本文件规定了一个频率计权特性,标记为G,用于测定部分或全部频谱位于1 Hz~20 Hz频段内的声音或噪声的计权声压级。
注1: 对于频谱覆盖次声与可听声频段的宽带声,用本文件测定的次声计权声压级是对仅覆盖可听声频段的标准化方法针对该噪声的描述量(如A 计权声压级)的补充。通常这些量的结果和G 计权的结果不同,但不必关注该差异,因为各自的结果涉及的噪声频率范围不同且几乎没有重叠。
