Résumé

Les mesures de coefficients d’absorption de 2 échantillons dans 4 salles réverbérantes équipées de façon semblable et d'un volume variant entre 16 m3 et 250 m3 montrent des différences significatives en basses fréquences. Il existe une relation presque linéaire entre le coefficient mesuré et le logarithme du volume de la salle. Cette relation pourrait expliquer en partie la variabilité des coefficients mesurés d'un laboratoire â l'autre.
