Acoustics. Preferred reference values for acoustical and vibratory levels Ingestion-build-156411 It’s for:BS EN ISO 1683: 2008 Acoustics. Preferred reference values for acoustical and vibratory levels BS EN ISO 1683 specifies reference values used in acoustics, in order to establish a uniform basis for the expression of acoustical and vibratory levels. The reference values are mandatory for use in acoustics for airborne and structure borne sound, but may also be used in other applications.
