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 Ingestion-build-2058401 Scope 1. 1 General This International Standard specifies an approximate method of characterizing sources of structure borne sound by the measurement of one third octave band free velocity level spectra (or, if appropriate, octave band velocity level spectra) on the supports or other connection points of machines mounted on resilient isolators. This structure borne sound emission is considered with respect to the airborne or liquid borne sound
