The purpose of this part of ISO 717 is to standardize a method
26、 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 be examples and therefore are not complete.

28、s, floors, doors, and windows;b) takes into consideration the different sound level spectra of various noise sources such as noise sources inside a building and traffic outside a building;c) gives rules for determining these quantities from the results of measurements carried out in one-third-octave
29、 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 for rating airborne sound insulation and for simplifying the formulation of acoustical requirements in building codes. An additional single-numb
30、er 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 single-number quantities are specified according to varying needs. The single-number quantities are based on results of measurements in one-thi
31、rd-octave bands or octave bands.For laboratory measurements made in accordance with ISO 10140, single-number quantities should be calculated using one-third-octave bands only.The rating of results of measurements carried out over an enlarged frequency range is dealt with in Annex B.2 Normative refer
