ISO 1683:2015 pdf download.Acoustics — Preferred reference values for acoustical and vibratory levels
1 Scope
This International Standard 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 sounds in air and other gases, sounds in water and other liquids, and for structure-borne sound, but can also be used in other applications.
