The wor
11、k of preparing International Standards is normally carried out through ISO technical committees. Each member body interested 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-governme
12、ntal, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft
13、 International Standards adopted by the technical 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. International Standard ISO 14163 was prepared by Technical Committee ISO/TC 43
14、, Acoustics, Subcommittee SC 1, Noise. Annexes A to C of this International Standard are for information only.

Silencers have numerous applications and different designs ba

19、election of silencers for noise control in gaseous media. It specifies the acoustical and operational requirements which are to be agreed upon between the supplier or manufacturer and the user of a silencer. The basic principles of operation are described in this International Standard, but it is no
20、t a silencer design guide. The silencers described are suitable, among others, for attenuating system noise and preventing crosstalk in heating, ventilation and air-conditioning (HVAC) equipment; for preventing or reducing sound transmission through ventilation openings from rooms with high inside s
21、ound levels; for attenuating blow-off noise generated by high-pressure lines; for attenuating intake and exhaust noise generated by internal combustion engines; and for attenuating intake and outlet noise from fans, compressors and turbines. They are classified according to their types, performance
22、characteristics and applications. Active and adaptive passive noise-control systems are not covered in detail in this International Standard. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International
23、 Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indica
24、ted below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.
