Embodiment Construction

[0043] figure 1 A not-to-scale ceiling plan of hall 01 with reduced reverberation time according to the invention is shown. The floor area of ​​the hall extends for example 21.5 m x 17.5 m. The hall is equipped with a sound absorber installation according to the invention, which is designed as a sound-absorbing roof structure. Hall 01 has walls 02 and three built-in roof girders 03 that carry the roof skin 06 ( figure 2 ). Absorber strips 04 are respectively attached to the sides of the roof girders 03 , and these absorber strips cover substantially the entire side. In the example shown, the roof girders with absorbing strips laid on both sides are spaced about 5.4m from each other. Approximately the same distance also exists between the end walls and the respective immediately adjacent roof girders. Between the roof girders 03 there are in each case sections of the roof skin 06 which are reverberant and whose width is greater than twice the average height of the roof gi...

Abstract

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.

Description

technical field [0001] The invention relates to a sound-absorbing roof structure of a hall, a sound-absorber installation and a hall with reduced reverberation time using sound-absorbing elements and a sound-absorbing absorber strip formed from such elements. Background technique [0002] Components for improving room acoustics, ie for better speech intelligibility and sound absorption for hearing protection, have been known for a long time. Acoustic ceilings made of plasterboard or fiberboard improve room acoustics, reduce echoes and convert sound energy into heat. Furthermore, acoustic wall claddings are known, such as panels in various angles and sizes that are fitted to walls and are used as low frequency absorbers for absorbing low sound frequencies. In order to absorb high sound frequencies it is common to use perforated plates which are fitted at a specific distance from the wall. There is a sound-absorbing and sound-blocking material, such as foam or felt, between ...
