26、dwide 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 be represented on
27、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. Draft International Standards adopted
28、 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 140-5 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 2,
29、Building acoustics. This second edition cancels and replaces the first edition (ISO 140-5:1978), which has been technically revised. ISO 140 consists of the following parts, under the general title Acoustics Measurement of sound insulation in buildings and of building elements: Part 1: Requirements
30、of laboratory test facilities with suppressed flanking transmission; Part 2: Determination, verification and application of precision data; Part 3: Laboratory measurement of airborne sound insulation of building elements; Part 4: Field measurements of airborne sound insulation between rooms; Part 5:

34、, (c) BSI EN ISO 140-5:1998 BSI 05-19991 1 Scope This part of ISO 140 specifies two series of methods (element methods and global methods) for measurement of the airborne sound insulation of faade elements and whole faades, respectively. The element methods aim to estimate the sound reduction index
35、of a faade element, for example a window. The most accurate element method uses a loudspeaker as an artificial sound source. Other, less accurate, element methods use available traffic noise. The global methods, on the other hand, aim to estimate the outdoor/indoor sound level difference under actua
36、l traffic conditions. The most accurate global methods use the actual traffic as sound source. In addition, a loudspeaker may be used as an artificial sound source. An overview of the methods is given in Table 1. The element loudspeaker method yields an apparent sound reduction index which, under ce
37、rtain circumstances e.g. taking account of measurement precision (see 7.1), can be compared with the sound reduction index measured in laboratories in accordance with ISO 140-3 or ISO 140-10. This method is the preferred method when the aim of the measurement is to evaluate the performance of a spec
38、ified faade element in relation to its performance in the laboratory. The element road traffic method will serve the same purposes as the element loudspeaker method. It is particularly useful when, for different practical reasons, the element loudspeaker method cannot be used. These two methods will
39、 often yield slightly different results. The road traffic method tends to result in lower values of the sound reduction index than the loudspeaker method. In Annex D this road traffic method is supplemented by the corresponding aircraft and railway traffic methods. The global road traffic method yie
40、lds the real reduction of a faade in a given place relative to a position 2 m in front of the faade. This method is the preferred method when the aim of the measurement is to evaluate the performance of a whole faade, including all flanking paths, in a specified position relative to nearby roads. Th
41、e result cannot be compared with that of laboratory measurements. The global loudspeaker method yields the sound reduction of a faade relative to a position 2 m in front of the faade. This method is particularly useful when, for different practical reasons, the real noise source cannot be used. The
42、result cannot be compared with that of laboratory measurements.
