Abstract

The invention relates to a panel for acoustic treatment involving fragmentation of the reverberated sound. The inventive panel (2) is formed by an assembly of tubular elements of variable cross-section (1), comprising two faces with different sound transmission properties, namely: an open face which enables sound transmission and which is shown in the figure, and an opposing closed face which mainly reflects sound. According to the invention, the closed face is positioned facing an enclosure, at a distance therefrom, such that an incident sound pulse on the open face reaches the enclosure, is then reflected towards the closed face from where it is once again reflected towards the enclosure, thereby reverberating for a time between the enclosure and the panel. Of each incident pulse on the closed face, only a small part of the reverberated pulse passes therethrough, such that the incident pulse returned to the room is transformed into a series of successive fragments with much smaller and decreasing intensity, which are separated from one another by time intervals that are proportional to the distance between the panel and the enclosure.
