Acoustics - Rating of sound insulation in buildings and of building elements - Part 1 : airborne sound insulation

This documenta) 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 and traffic outside a building, andc) gives rules for determining these quantities from the results of measurements carried out in one-third-octave or octave bands for example in accordance with ISO 10140-2 and ISO 16283-1.The single-number quantities in accordance with this document are intended 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 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 10140-2, single-number quantities are 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.

Acoustics - Rating of sound insulation in buildings and of building elements - Part 1 : airborne sound insulation

This document

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 and traffic outside a building, and

c) gives rules for determining these quantities from the results of measurements carried out in one-third-octave or octave bands for example in accordance with ISO 10140-2 and ISO 16283-1.

The single-number quantities in accordance with this document are intended 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 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 10140-2, single-number quantities are 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.

Acoustics - Rating of sound insulation in buildings and of building elements - Part 1 : airborne sound insulation

ISO 717-1:2013: 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 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 ISO 717-1:2013 are intended 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 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-octave bands only. The rating of results of measurements carried out over an enlarged frequency range is dealt with in an annex.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
