Large room roof sound absorption structure for reducing reverberation time

摘要

The invention relates to a sound-absorbing roof construction of a hall (01) having walls (02), a plurality of roof trusses (03), which lie on the walls (02) at least at the ends of said roof trusses, and a sound-reflecting roof covering (06) supported by the roof trusses (03). Absorber strips (04) composed of sound absorber elements are applied to the side surfaces of a plurality of the roof trusses (03). Between adjacent roof trusses (03) having the absorber strips (04), a sound-reflecting portion of the roof covering (06) having a width that is at least twice the average height of the roof trusses (03) extends. The invention further relates to a sound absorber assembly having sound absorber elements, which are arranged in a hall (01) having walls (02) and having a roof construction that closes off the hall in the upward direction, the roof construction comprising a plurality of roof trusses (03) and a roof covering (06) supported by said roof trusses. According to the invention, absorber strips (04) composed of sound absorber elements strung together are applied to the two side surfaces of a plurality of the roof trusses (03). The invention finally relates to a hall (01) having reduced reverberation time, which hall uses the sound absorber assembly.
