标准摘要
[中文适用范围]： 通过测量安装在弹性隔振器上的机器支架上的三分之一倍频程自由速度级谱来表征结构声源的近似方法。 [外文原描述]： Approximate method of characterizing sources of structure-borne sound by the measurement of one-third-octave-band free velocity level spectra on the supports of machines mounted on resilient isolators.
英文名称Acoustics — Characterization of sources of structure-borne sound with respect to sound radiation from connected structures — Measurement of velocity at the contact points of machinery when resiliently mounted
