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.


The 46-year-old Icelandic artist, Ragnar Kjartansson, is re-creating the 1980s US daytime soap Santa Barbara for a new project due to be unveiled at GES-2, the vast new culture complex in Moscow. The historic 20,000 sqm venue, home to the V-A-C Foundation, opens early December 2021. A former power plant built in 1907, converted by the Italian architect Renzo Piano, which could become as important on the global art circuit as London’s Tate Modern or the Centre Pompidou in Paris.

Evan Green, Acoustician and Associate at Kahle Acoustics is invited as guest speaker to the Seminar Raumakustik Intensiv — Musikverein Edition held from 22nd until 24th November 2021 in Vienna. Complexity and beauty of room acoustics will be discussed intensely, from basics for advanced users to concert hall acoustics and digital acoustics.

The V-A-C Foundation approached Renzo Piano's studio with a proposal to turn the power plant, which supplied energy for the City of Moscow for almost a century, into a new cultural space — the GES-2. The end result will open its doors next Dec 4th 2021 in Moscow. Read more on AD Architecture online magazine, and browse through the 3D model. More info in our website.
