Acoustics - Determination of high-frequency sound power levels emitted by machinery and equipment 声学.机械和设备发出的高频声功率级的测定

发布日期： 2019-03-19

本标准的目的是规定四种方法，用于在以16 kHz为中心的倍频带（包括11.2 kHz和22.4 kHz之间的频率）覆盖的频率范围内，测定机械和设备发出的高频噪声的声功率级。它们是对ISO 3741和ISO 3744中描述的方法的补充。

The objective of this Standard is to specify four methods for the determination of the sound power levels of high-frequency noise emitted by machinery and equipment in the frequency range covered by the octave band centred at 16 kHz, which includes frequencies between 11,2 kHz and 22,4 kHz. They are complementary to the methods described in ISO 3741 and ISO 3744.
