The work 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, governmentai and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnicai Commission (IEC) on all matters of electrotechnical standardization. Draft Internationai Standards adopted by the technicai committees are circulated to the member bodies for voting. Publication as an International a vote International Standard ISO 8297 was prepared by Technical Committee SO/TC43,Acoustics.SubcommitteeSc1,Noise.
