Acoustics - Measurement and parametric description of spatial sound distribution curves in workrooms for evaluation of their acoustical performance (ISO 14257:2001)

Akustik - Messung und Parametrisierung von Schallausbreitungskurven in Arbeiträumen zum Zweck der Beurteilung der akustischen Qualität der Räume (ISO 14257:2001)

Diese Internationale Norm legt ein Verfahren zur messtechnischen Bestimmung der Schallausbreitungskurve(n) in einem vorhandenen Arbeitsraum fest. Außerdem wird ein Verfahren zur Bestimmung zweier Kenngrößen für die raumakustischen Eigenschaften eines Arbeitsraumes aus den Messdaten festgelegt. Die  Beschreibungsgrößen sind die Schalldruckpegelüberhöhung verglichen mit Freifeldbedingungen und die Schalldruckpegelabnahme je Abstandsverdopplung.
Diese Internationale Norm befasst sich nicht mit der Beurteilung der akustischen Qualität im Hinblick auf Sprachverständlichkeit oder andere psychologische Faktoren.
Unter der Voraussetzung, dass die Anzahl der Mikrofonpositionen die Durchführung der Regressionsrechnung erlaubt, ist diese Internationale Norm anwendbar auf Arbeitsräume jeder beliebigen Form und Größe.

Acoustique - Mesurage et description paramétrique des courbes de décroissance sonore spatiale dans les locaux de travail en vue de l'évaluation de leur performance acoustique (ISO 14257:2001)

La présente Norme internationale spécifie une méthode de mesurage de la (des) courbe(s) de décroissance sonore spatiale d'un local de travail donné. Une méthode est fournie pour déterminer, à partir des données mesurées, deux descripteurs de la performance acoustique d'un local de travail vis à vis de la réduction du bruit, à savoir l'amplification du niveau de pression acoustique par rapport au champ libre et le taux de décroissance spatiale du niveau de pression acoustique par doublement de la distance.  La présente Norme internationale ne traite pas de l'évaluation de la qualité acoustique vis-à-vis de la communication parlée ou d'autres facteurs psychologiques.  La présente Norme internationale s'applique aux locaux de travail de toute forme et de toutes dimensions pourvu que le nombre de positions microphoniques permette le calcul de régression.
