Résumé

Des unites absorbantes, sont en usage commun afin de contrôler le bruit et la reverberation dans le batîment. L'effet d'absorbtion de ces absorbants ci un nombre supérieur à une unité par deux metres carrés (1 uni te/2 m2) a dé'.ja été recherché. Cependant, peu d'information existe au sujet de densités moindre à celle-ci. Afin de mieux comprendre ces charatéristiques d'absorbtion, des test en laboratoire ont été éffectué avec différentes configurations et densités moins d'une unité/2 m2. Spécifiquement l'éffet de l'orientation horizontal et vertical, et^de 1'éfficacite d'absorbtion due au nombre d'absorbants par metre carré a été investigué. Les ^résultats indiquent que l'orientation a peu d'influence mais que 1 'éffi caci te d'absorbtion par unité augmente quand leur nombre par metre carré diminue.
