This documenta) defines single-number quantities for impact sound insulation in buildings and of floors,b) gives rules for determining these quantities from the results of measurements carried out in one-third-octave bands in accordance with ISO 10140-3 and ISO 16283-2, and in octave bands in accordance with that option in ISO 16283-2 for field measurements only,c) defines single-number quantities for the impact sound reduction of floor coverings and floating floors calculated from the results of measurements carried out in accordance with ISO 10140-3, andd) specifies a procedure for evaluating the weighted reduction in impact sound pressure level by floor coverings on lightweight floors.The single-number quantities in accordance with this document are intended for rating impact 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 where it is needed for the expression of uncertainty (except for spectrum adaptation terms). Numerical values of the single-number quantities are specified where required for calculations.The rating of measurements over an enlarged frequency range is given in Annex A.A method for obtaining single-number quantities for bare heavy floors according to their performance in combination with floor coverings is given in Annex B.Example calculations of single-number quantities are given in Annex C.The rating of measurements with a heavy and soft impact source (rubber ball) is given in Annex D.

L'objet du présent document est de normaliser une méthode permettant de convertir les valeurs d'isolement au bruit de choc en fonction de la fréquence en une valeur unique apte à caractériser la performance acoustique. Il définit des valeurs uniques de l'isolement acoustique des immeubles et des planchers au bruit de choc, Il spécifie des règles de détermination de ces valeurs d'après les résultats de mesurages effectués dans des bandes de fréquences de tiers d'octave et d'octave pour des mesurages sur site seulement, définit des valeurs uniques de la réduction du bruit de choc par les revêtements de sol et les planchers flottants, spécifie un mode opératoire d'évaluation de la réduction du niveau de bruit de choc pondéré par les revêtements de sol sur des planchers légers. Les valeurs uniques spécifiées dans le présent document sont destinées à indiquer la qualité de l'isolement acoustique aux bruits de choc 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 0,1 dB pour exprimer l'incertitude, d'inclure l'Amendement 1 existant de la NF EN ISO 717-2, de mettre à jour les références normatives.
