适用范围：This part of ISO 4412 describes procedures for the determination of the sound power levels of a hy-draulic fluid power pump, under controlled con-ditions of installation and operation, suitable for providing a basis for comparing the noise levels of pumps in terms of — A-weighted sound power level; — one-third octave band power level. From these sound power levels, if required, refer-ence sound pressure levels may be calculated for reporting purposes (see clause 11). For general purposes, the frequency range of inter-est includes the one-third octave bands with centre frequencies between 100 Hz and 10000 Hz.
