16、08 All rights reserved iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested
17、 in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Comm
18、ission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technic
19、al committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO sha
20、ll not be held responsible for identifying any or all such patent rights. ISO 1683 was prepared by Technical Committee ISO/TC 43, Acoustics. This second edition cancels and replaces the first edition (ISO 1683:1983), which has been technically revised. Licensed CopyChinese University of Hong Kong, 1

In order to establish a uniform basis for the expression of those level
22、s, 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 negat
23、ive) 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 several decades. For air
24、borne sound, a special reference value for sound pressure is stated according to widespread use and legal implications.

25、1 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 acou
26、stics for airborne and structure-borne sound, but may also be used in other applications. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition
27、 of the referenced document (including any amendments) applies. ISO 2041:1) , Mechanical vibration, shock and condition monitoring Vocabulary ISO/TR 25417, Acoustics Definitions of basic quantities and terms 3 Terms and definitions For the purposes of this document, the terms and definitions given i
28、n ISO 2041 and ISO/TR 25417 and the following apply. 3.1 reference value quantity value used as a basis for comparison with values of quantities of the same kind ISO/IEC Guide 99:2007, 5.18 NOTE For the purposes of this International Standard, a reference value is expressed in terms of a number and
29、an appropriate unit of measurement used to form a ratio of dimension one when defining a logarithmic quantity. 4 Specifications 4.1 Reference values for airborne sound quantities Reference values for various airborne sound quantities are given in Table 1. 1) To be published.

In this event, the vi
33、bratory velocity level takes values close to the associated sound pressure and sound intensity levels. c In connection with structure-borne sound, a reference value of 10 m/s2 is also in use.
