SOUND-ABSORBING ROOF CONSTRUCTION OF A HALL HAVING REDUCED REVERBERATION TIME

HOPPE CHRISTIAN / TOBER ELMAR JOHANNES ANTON / TSCHIERSCH RONALD

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 thatcloses 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.

本发明涉及大厅(01)的吸音的屋顶结构，大厅具有墙壁(02)、多个至少在它们的端部处安置在墙壁(02)上的屋顶桁梁(03)和由屋顶桁梁(03)承载的反射声音的屋顶表层(06)。在其中多个屋顶桁梁(03)的侧面上装配有吸收条(04)，吸收条由吸音器元件组合而成。在具有吸收条(04)的相邻的屋顶桁梁(03)之间分别延伸有屋顶表层(06)的反射声音的区段，该区段具有至少为屋顶桁梁(03)的平均高度的两倍的宽度。本发明还涉及具有吸音器元件的吸音器设施，吸音器设施布置在大厅(01)中，大厅具有墙壁(02)和向上封闭大厅的屋顶结构，其中，屋顶结构具有多个屋顶桁梁(03)和由这些屋顶桁梁承载的屋顶表层(06)。根据本发明，在其中多个屋顶桁梁(03)的两个侧面上装配有由彼此排列成行的吸音器元件组合而成的吸收条(04)。最后，本发明涉及具有降低的混响时间的大厅(01)，该大厅使用吸音器设施。
