Акустика. Определение уровней звуковой мощности источников шума по интенсивности звука. Часть 1. Измерения в отдельных точках
Название (англ.):
Acoustics. Determination of sound power levels of noise sources using sound intensity. Part 1. Measurements at discrete points
Описание (англ.):
Specifies a method for measuring the component of sound intensity normal to a measurement surface which is chosen so as to enclose the noise source(s) of which the sound power level is to be determined. The one-octave, one-third-octave or band-limited weighted sound power level is calculated from the measured value. The method is applicable in situ or in special purpose test environments to anysource for which a physically stationary measurement surface can be defined, and on which the noise generated by the source is stationary in time.
