5、Acoustics” in collaboration with Technical Committee CEN/TC 211 “Acoustics” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Akustik, Lrmminderung und Schwin-gungstechnik im DIN und VDI (Acoustics, Noise Control and Vibration Engineering St
6、andards Committee in DIN and VDI), Working Committee NA 001-01-02 AA Akustik Geruschimmission Grundlagen, Ermittlung, Beurteilung. Throughout the revision of ISO 1683 the German mirror committee and other German experts argued vehemently for the specification of m/sn500=v as a preferred velocity ref
7、erence value, in the light of the airborne sound quantities given in Table 1. However, the international majority was not in agreement with this well-founded request. From the point of view of the German mirror committee the preferred vibratory velocity reference value of m/sn10=v now given in Table
8、 3 has no correlation whatever to the other basic reference values for airborne sound quantities, and will necessitate corrections to numerous basic technical rules. This conflict can be solved by using the reference value m/sn500=v cited in footnote b to Table 3. Since footnotes in tables are norma
9、tive elements, use of this value will not compromise conformity with this standard. The DIN Standard corresponding to the International Standard referred to in this document is as follows: ISO 80000-8 DIN EN ISO 80000-8 For the International Standard referred to in the Bibliography of this document

In order to establish a uniform basis for the expression of those lev
24、els, a set of agreed reference values is 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 nega
25、tive) rather than both positive and negative.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
26、 reference value for sound pressure is stated according to widespread use and legal implications.4DIN EN ISO 1683:2015-09 EN ISO 1683:2015 (E) 1 ScopeThis International Standard specifies reference values used in acoustics, in order to establish a uniform basis for the expression of acoustical and v
27、ibratory 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 following documents, in whole or in part, are normatively

36、d pressure and distance (for which the reference value is 1 Pa m) or sound exposure and squared distance (for which the reference value is 1 Pa2m2s). Ratios of these compound quantities to other sound quantities lead to further compound quantities with dimensions of distance (with reference value 1
