Sustainable acoustic optimization provides solutions that take sustainability and acoustics into account

Acoustics is our passion. For over 90 years, our researchers in the Acoustics department have been working on innovative solutions for architectural and room acoustics, the acoustics of installations and silencers, and for applications in buildings, vehicles and aircraft. Our Life Cycle Engineering department has been addressing the sustainable design of products and solutions for more than 35 years. We are now pooling our expertise to develop acoustic solutions that meet the highest sustainability standards.

Future requirements for components and constructions, such as wall constructions, component ceilings and ceiling overlays, must take sustainability aspects into account. This is not only required by law but is also increasingly recognized as a necessity to mitigate climate change and conserve our limited resources. Sustainability is anchored in law and society by European legislation (EU Taxonomy Regulation). This is reinforcing the need for sustainable business practices and will be crucial for market success in the future. Companies are therefore increasingly feeling obliged to put their products and manufacturing methods to the test.
 

Special expertise in the field of sustainable sound absorbers

The scientists in the Acoustics department have proven expertise in developing absorbers. An example of this is the development of low-frequency absorbers such as the compound plate resonator (CPR), a highly effective solution for absorbing low frequencies in the range of 63 Hz to 125 Hz. Other developments include the broadband compact absorber (BBCA) or micro-perforated absorbers, which, besides offering high sound absorption in the lower or medium frequency range, can also be transparent. Further absorber developments are based on this, such as the strip absorber or a partition curtain for use in sports halls with excellent broadband absorption. The latest approaches include the development of sound absorbers made from renewable raw materials, where sustainability is already taken into account during the development of materials and constructions.

Our approach: Bringing acoustics and sustainability together

We are your partner for researching and developing sustainable acoustic components, wall constructions, component ceilings and ceiling overlays. By combining acoustic expertise and sustainability analyses, we offer solutions for:

• Room acoustics: Compliance with requirements such as those in accordance with DIN 18041, VDI 2569, ITU BS 1116, ASR A3.7, DIN 15996
• Technical acoustics: Eliminating low-frequency interference and problems
• Sound insulation: Lowering high noise levels
• Building acoustics: Sustainably optimizing products and constructions without impairing their sound insulation properties
• Musical acoustics: For opera houses, concert halls, rehearsal rooms, theaters, recording studios, film studios and cinemas
• Technical sound insulation: Quieter and more sustainable systems and constructions
• Vehicles and airplanes: Reducing noise using sustainable materials and constructions
• Household appliances and other technical applications: Making necessary acoustic measures more sustainable

During development and optimization, we consider the entire value creation process. In this way, we make sure that our technology not only meets future requirements in technical terms, but also in ecological, economic and social terms.

We have the know-how to develop highly-effective and sustainable acoustic solutions for your application and to help you implement them in products. Get in touch with us!
