    25、zation) 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 in a subject for which a technical committee has been established has the right to b

    26、e 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 Commission (IEC) on all matters of electrotechnical standardization. International Standa

    27、rds 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 technical committees are circulated to the member bodies for voting. Publication as an Inter

    28、national 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 shall not be held responsible for identifying any or all such patent rights. ISO 354 was

    29、 prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building acoustics. This second edition cancels and replaces the first edition (ISO 354:1985), which has been technically revised, as follows: an integrated impulse response method has been introduced; the requirement to measu

    30、re at least 36 decays has been added; mounting conditions according to ISO 354:1985:Amd.1:1997 and mounting conditions Type B and Type J have been introduced. ENISO354:2003ISO 354:2003(E) vIntroduction When a sound source operates in an enclosed space, the level to which reverberant sound builds up,

    31、 and the subsequent decay of reverberant sound when the source is stopped, are governed by the sound-absorbing characteristics of the boundary surfaces, the air filling the space, and objects within the space. In general, the fraction of the incident sound power absorbed at a surface depends upon th

    32、e angle of incidence. In order to relate the reverberation time of an auditorium, office, workshop, etc., to the noise reduction that would be effected by an absorbing treatment, knowledge of the sound-absorbing characteristics of the surfaces, usually in the form of a suitable average over all angl

    33、es of incidence, is required. Since the distribution of sound waves in typical enclosures includes a wide and largely unpredictable range of angles, a uniform distribution is taken as the basic condition for the purposes of standardization. If, in addition, the sound intensity is independent of the

    34、location within the space, the sound distribution is called a diffuse sound field, and the sounds reaching a room surface are said to be at random incidence. The sound field in a properly designed reverberation room closely approximates a diffuse field. Hence, sound absorption measured in a reverber

    35、ation room closely approximates the sound absorption that would be measured under the basic conditions assumed for standardization. The purpose of this International Standard is to promote uniformity in the methods and conditions of measurement of sound absorption in reverberation rooms. ENISO354:2003
