Well-being in the office

Room acoustics.
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.

The absorbers are available with metal and fabric finishes and can be produced in any colour.

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.

Efficacy of absorbers

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.

Key acoustic parameters

The reverberation time T and the sound absorption coefficient αw are particularly important for assessing room acoustics. The reverberation time describes how long sound remains in the room and is influenced by factors such as room volume, room geometry, surface texture and furnishings.

Selection of absorber elements

The sound absorption coefficient is determined by the absorptive properties of the materials onto which the sound strikes. The choice of suitable absorber elements depends on the customer’s specific requirements, the use and geometry of the room, and the layout of the workstations.

Optimal listening conditions

Room acoustics are influenced by the sound-absorbing properties of materials and their positioning. When sound strikes absorbent surfaces, some of the sound energy is absorbed and transformed. High-quality absorbers reduce the sound level and ensure better audibility in the room.

Operating principle of partition wall absorbers

The System 7000 combines both, building and room acoustics in order to function as a broadband absorber. 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. The 2000 and 2300 partition wall systems are available in two wall thicknesses (100 and 125 mm). This allows sound insulation and sound absorption to be combined using the Strähle acoustic partition wall.

Room acoustics parameters

Reverberation time Tthe time for the sound pressure level to sink by 60 dB from when it was created
Absorption rating αproportion of sound energy which is not reflected; complete reflection α = 0; complete absorption: α = 1
Rated sound absorption coefficient
αw		Refers to the comparison of the frequency response of materials and products with a reference curve. The absorption capacity is measured in the anechoic chamber of an accredited institute using standardised methods. The standardised reference curve is used to calculate the weighted absorption coefficient as a single value. This is read at 500 Hz.

Acoustic systems for a pleasant working environment

Communication, presentations, meetings, concentration: the functions of a room are as varied as the requirements for its acoustic design. Strähle acoustic systems can be easily integrated into existing structures, whether as part of a new build or for subsequent optimisation.

FAQs

Acoustic elements and sound absorbers improve room acoustics by absorbing incident sound and reducing the reverberation time in the room. 

Strähle offers partition wall absorbers, ceiling-mounted absorbers, wall-mounted absorbers, glass wall absorbers and free-standing absorbers. Depending on the room concept and acoustic requirements, different combinations of absorber types can also be installed together to ensure the best possible room acoustics.

Yes. Acoustic elements can also be installed retrospectively. They can be flexibly integrated into existing room concepts and adapted to meet the relevant acoustic requirements.

Yes. Acoustic elements are designed to reduce reverberation within rooms. They increase the sound absorbing surface area, improving the absorption of sound waves and minimising their reflection. This shortens the reverberation time.

Yes. Acoustic elements improve speech intelligibility by reducing reverberation. This makes conversations clearer and easier to understand.

Wall-mounted, ceiling-mounted and free-standing acoustic elements absorb incident sound waves and thus lessen sound reflections within the room. This reduces the reverberation time. At the same time, distracting noises and noise emissions are significantly reduced, which contributes to more pleasant room acoustics.
 

Yes. Partition wall absorbers can be flush mounted into partition wall systems. This improves the room acoustics without compromising the function or appearance of the partition wall. The integrated acoustic elements reduce reverberation, make speech clearer and easier to understand, and contribute to a comfortable working environment.

Acoustic elements are available in a wide variety of colours and surface finishes, and can be individually tailored to the room and design concept. Depending on the design, visible micro-perforations with high quality powder coating in RAL, NCS or other colour systems are available. Alternatively, fabric coverings in tried-and-tested fabrics from a variety of manufacturers are also available. Complementary wooden absorbers with real wood veneer or a tough HPL coating can also be implemented.
