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.

L'objet du présent document est de normaliser une méthode permettant de convertir les valeurs d'isolement aux bruits aériens en fonction de la fréquence en une valeur unique apte à caractériser la performance acoustique. Il définit des valeurs uniques de l'isolement aux bruits aériens des immeubles et des éléments de construction tels que murs, planchers, portes et fenêtres. Il prend en considération les différents spectres sonores de sources de bruit variées telles que des sources de bruit à l'intérieur d'un immeuble et du trafic à l'extérieur d'un immeuble. Il spécifie des règles de détermination de ces valeurs d'après les résultats de mesurages effectués dans des bandes de fréquences d'une largeur de tiers d'octave ou d'octave. Les valeurs uniques spécifiées dans le présent document sont destinées à indiquer la qualité de l'isolement aux bruits aériens et à faciliter l'énoncé des exigences en matière d'acoustique dans les règles techniques de la construction. Le présent document a pour but de permettre l'utilisation de pas de pondération de 0,1 dB pour exprimer l'incertitude, d'inclure l'Amendement 1 existant de la NF EN ISO 717-1, de mettre à jour les références.
