Acoustics — Noise emitted by machinery and equipment — Determination of emission sound pressure levels at a work station and at other specified positions from the sound power level
声学——机械和设备发出的噪音——从声功率级确定工作站和其他指定位置的发射声压级
Specifies two methods for determining the emission sound pressure levels of machinery and equipment at a work station and at other specified positions nearby, by calculation from the sound power level. Permits the comparison of the sound power of different units of a given family of machinery.
