In order to establish a uniform basis for the expression of those levels, a set of agreed reference values is

24、 needed.The reference value determines whether the level for a particular quantity is positive or negative. For general measurements and many engineering specifications, it is desirable that levels of a given kind be consistently positive (or consistently negative) rather than both positive and nega

25、tive.In general, a reference value is expressed as the number one and a derived SI unit formed by the use of an appropriate SI prefix.The values specified in this International Standard represent the values internationally adopted.For airborne sound, a special reference value for sound pressure is s

26、tated according to widespread use and legal implications.

27、 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.2 Normative referencesThe fol

37、s to other sound quantities lead to further compound quantities with dimensions of distance (with reference value 1 m) or area (with reference value 1 m2).2 ISO 2015 All rights reservedBS EN ISO 1683:2015ISO 1683:2015(E)4.3 Reference values for vibratory quantitiesReference values for various vibrat
