20、03ISO -681511:(0002E) iv ISO 0002 All irhgts seredevr 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.
21、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-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Internat
22、ional 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 International Standards adopted by the technical committees are circulated to the member bodies
23、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 part of ISO 15186 may be the subject of patent rights. ISO shall not be held responsible for identifyin
24、g any or all such patent rights. International Standard ISO 15186-1 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building acoustics. ISO 15186 consists of the following parts, under the general title Acoustics Measurement of sound insulation in buildings and of buildi
25、ng elements using sound intensity: Part 1: Laboratory measurements Part 2: Field measurements Part 3: Laboratory measurements at low frequencies Annexes A and B of this part of ISO 15186 are for information only.

26、 1 Acoustics Measurement of sound insulation in buildings and of building elements using sound intensity Part 1: Laboratory measurements 1 Scope This part of ISO 15186 specifies a sound intensity method to determine the sound reduction index and the element- normalized level difference of building e
27、lements. The method can be used as an alternative to ISO 140-3 and ISO 140-10 respectively. One important use is when the traditional ISO 140-3 method fails because of high flanking transmission. The reproducibility of this intensity method is estimated to be equal to or better than that of ISO 140-
28、3. NOTE Some information about the accuracy with which this part of ISO 15186 can reproduce the sound reduction index measured according to ISO 140-3 is given in annex A. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute pro
29、visions of this part of ISO 15186. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 15186 are encouraged to investigate the possibility of applying the most recent edition of the normativ

To account for this fact, if the aim of the intensity measurements is to simulate measurements according to ISO 140-3, the intensity sound reduction index should be modified as above. NOTE
