Fine acoustic is not there to be seen but should blend into the architecture.

Kahle Acoustics specialises in acoustics consulting for performing arts buildings, including concert halls, opera houses, theatres, and auditoria.

Our projects include new buildings, renovations and acoustic improvements, as well as the conversion of existing and “found” spaces.

Rather than applying preconceived ideas, Kahle Acoustics seeks optimised solutions that take context, culture, architectural design and artistic merit into account. In every case, the goal is to find a perfectly adapted solution that optimises the acoustics along with all other requirements.

To achieve this aim, and to avoid acoustic solutions that are “bolted on”, Kahle Acoustics is proactive in collaborating with the project architect, theatre consultant and user/client to integrate acoustics right from the very start.

Every member of Kahle Acoustics has a background both in music and science — through this we are highly attuned to the requirements of musicians, audience and performers alike. This perspective is essential when it comes to our work developing the brief for performance spaces in new or existing buildings.

Kahle Acoustics is located in Brussels, Belgium, and was founded in 2001 by Eckhard Kahle. All members work in multiple languages: French, English, Dutch and German, and on three continents: Europe, North America and Asia.

Kahle Acoustics frequently collaborates with some of the world's most prestigious architects, including Renzo Piano, Jean Nouvel, Rafael Viñoly, Paul Andreu, Rem Koolhaas, Eduardo Souto de Moura, David Chipperfield and Pekka Salminen.


In collaboration with Barteld Postma and Brian Katz, Kahle Acoustics contributed to research into Room Acoustics design strategies in the pre-Sabine era. Our article (pdf) includes fascinating insights and guidelines from before the discovery of the reverberation time formula. For contemporary room design, there is much food for thought to be found in old texts! More info on our LinkedIn.

Dear All, we are all working remotely but working still, so do all take care of yourselves and beloved ones and all the best until we meet again. Stay Home!
