We listen carefully.
In addition to good sound insulation, partition wall systems with integrated absorber elements from Strähle also optimise the acoustics within the room and ensure greater well-being and a working environment that enhances concentration. Together with our project partners, we develop a specific acoustics concept which optimises reverberation times, sound level differences and speech intelligibility. Our function is to harmonise the contrasting effects of building acoustics and room acoustics.
Strähle Acoustic Systems fulfil DIN norms 18041, VDI 2569 and ASR. The effectiveness of the absorbers depends on their positioning. The closer the source of sound is, the more efficiently it dampens the sound. Important parameters are the reverberation time T and the noise absorption rating w. Reverberation times depend on the volume of space, the geometry of the room, the surface properties and the furnishings. The absorption rating is calculated from the materials the sound meets. Which absorber elements are used depends on customers‘ requirements, the use of the room and its geometry, and the arrangement of workplaces.
Operating principle of partition wall absorbers
The System 7000 combines both building and room acoustics in order to function as a broadband absorber. The combination of absorption and sound insulation provides economic efficiency whilst also allowing for creative freedom.
Which surfaces are needed to create optimum indoor listening conditions? Room acoustics deals with the sound-absorbing properties of materials and their position in the room. The sound energy which meets the absorbing surface is transformed into other energy forms and absorbed. High-quality absorbers dampen the sound and improve the hearing quality of the room.
Reverberation time T: the time for the sound pressure level to sink by 60 dB from when it was created
Absorption rating w: proportion of sound energy which is not reflected; complete reflection aw= 0; complete absorption: aw = 1
