33、-5. The purpose of this part of ISO 717 is to standardize a method whereby the frequency-dependent values of airborne sound insulation can be converted into a single number characterizing the acoustical performance.References to standards which provide data for single-number evaluation are meant to

34、be examples and therefore are not complete.

35、1 ScopeThis part of ISO 717:a) defines single-number quantities for airborne sound insulation in buildings and of building elements such as walls, floors, doors, and windows;b) takes into consideration the different sound level spectra of various noise sources such as noise sources inside a building

36、 and traffic outside a building;c) gives rules for determining these quantities from the results of measurements carried out in one-third-octave or octave bands in accordance with ISO 10140-2, ISO 140-4, and ISO 140-5.The single-number quantities in accordance with this part of ISO 717 are intended

37、for rating airborne sound insulation and for simplifying the formulation of acoustical requirements in building codes. An additional single-number evaluation in steps of 0,1 dB is indicated for the expression of uncertainty (except for spectrum adaptation terms). The required numerical values of the

38、 single-number quantities are specified according to varying needs. The single-number quantities are based on results of measurements in one-third-octave bands or octave bands.For laboratory measurements made in accordance with ISO 10140, single-number quantities should be calculated using one-third

39、-octave bands only.The rating of results of measurements carried out over an enlarged frequency range is dealt with in Annex B.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
