Une bonne acoustique ne se voit pas, elle se fond dans l'architecture.

Société de conseil acoustique spécialisée dans les salles de concert et d'opéra, les théâtres et les auditoriums. Elle intervient dans la construction nouvelle, la rénovation, l'amélioration acoustique, la transformation d'un lieu existant en salle de concert ou de théâtre.

Plutôt que de préconiser un modèle de salle préétabli, Kahle Acoustics recherche la meilleure solution acoustique dans le respect du concept architectural et du projet artistique.

Pour que les solutions acoustiques ne viennent pas se plaquer artificiellement sur l'architecture, mais soient pensées en amont, Kahle Acoustics a pour principe de participer à l'élaboration du concept avec le client, l'architecte et le scénographe. Si nécessaire, la société contribue à définir le programme de la salle et/ou du bâtiment existant ou à construire.

Fondée en 2001 par Eckhard Kahle, Kahle Acoustics a son siège à Bruxelles. La société intervient en plusieurs langues — français, anglais, allemand, néerlandais — et sur trois continents — Europe, États-Unis, Asie.

Elle travaille avec des architectes de renommée internationale, tels que Renzo Piano, Jean Nouvel, Rafael Viñoly, Paul Andreu, Rem Koolhaas, Eduardo Souto de Moura, David Chipperfield et Pekka Salminen.
