28、tandardization) 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 ri
29、ght 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 International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedure
30、s used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial ru

34、oustics, Subcommittee SC 2, Building acoustics.This first edition of ISO 16283-2 cancels and replaces ISO 140-7:1998 and ISO 140-14:2004, which have been technically revised.ISO 16283 consists of the following parts, under the general title Acoustics Field measurement of sound insulation in building
35、s and of building elements: Part 1: Airborne sound insulation Part 2: Impact sound insulation Part 3: Faade sound insulation ISO 2015 All rights reserved vBS EN ISO 16283-2:2015ISO 16283-2:2015(E)IntroductionISO 16283 (all parts) describes procedures for field measurements of sound insulation in bui
36、ldings. Airborne, impact and faade sound insulation are described in ISO 16283-1, ISO 16283-2 and ISO 16283-3, respectively.Field sound insulation measurements that were described previously in ISO 140-4, ISO 140-5, and ISO 140-7 were a) primarily intended for measurements where the sound field coul
37、d be considered to be diffuse, and b) not explicit as to whether operators could be present in the rooms during the measurement. ISO 16283 (all parts) differs from ISO 140-4, ISO 140-5, and ISO 140-7 in that a) it applies to rooms in which the sound field might, or might not approximate to a diffuse
38、 field, b) it clarifies how operators can measure the sound field using a hand-held microphone or sound level meter and c) it includes additional guidance that was previously contained in ISO 140-14.NOTE Survey test methods for field measurements of airborne and impact sound insulation are dealt wit

40、asurements with an impact source operating on a floor or stairs in a building. These procedures are intended for room volumes in the range from 10 m3to 250 m3in the frequency range from 50 Hz to 5 000 Hz. The test results can be used to quantify, assess and compare the impact sound insulation in unf
41、urnished or furnished rooms where the sound field might, or might not approximate to a diffuse field.Two impact sources are described: the tapping machine and the rubber ball. These impact sources do not exactly replicate all possible types of real impacts on floors or stairs in buildings.The tappin
42、g machine can be used to assess a variety of light, hard impacts such as footsteps from walkers wearing hard-heeled footwear or dropped objects. A single number quantity can be calculated using the rating procedures in ISO 717-2. This single number quantity links the measured impact sound insulation
43、 using the tapping machine to subjective assessment of general impacts in dwellings that occur on floors or stairs in a building. The tapping machine is also well-suited to the prediction of impact sound insulation using ISO 15712-2. These two aspects facilitate the specification of impact sound ins
44、ulation in national building requirements using only measurements with the tapping machine as an impact source.The rubber ball can be used to assess heavy, soft impacts such as from walkers in bare feet or children jumping, as well as quantifying absolute values that can be related to human disturba
45、nce in terms of a Fast time-weighted maximum sound pressure level. At present, calculation procedures for a single number quantity do not currently exist in an ISO Standard.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispe
