A simple method for calculating the sound reduction by barriers in large rooms has been proposed. The theoretical considerations are on the basis of the method of the imaginary sources and Maekawa's method for calculating the sound reduction by barriers over a reflective surface.

Zusammenfassung

Es wird ein einfaches Verfahren zur Berechnung der Schalldämmung von Schallschirmen in großen Räumen vorgestellt. Die theoretischen Untersuchungen fußen auf der Methode der Spiegelquellen und dem Maekawaschen Verfahren zur Berechnung der Schalldämmung von Schallschirmen auf reflektierender Oberfläche.

Sommaire

On propose une méthode simple pour calculer la réduction du son par des barrières placés dans des locaux de grandes dimensions. La théorie utilisée s'appuie sur le principe des sources-images et sur la méthode de Maekawa pour le calcul de l'affaiblissement du bruit par des barrières reposant sur un sol réfléchissant.
