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 mounted1 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

Annex B (informative) Selection of the test levels

It is then immersed in a liquid and its apparent mass upon immersion is recorded to check the purity and concentration of a sample and gives insight into its composition

ISO 5178 is applicable to metallic materials in all forms of product with joints made by any fusion welding process

comprising two separate meter heads on a common mounting controlling two separate bays
