The Organization for Economic Cooperation and Development (OECD) is an international cooperation organization, composed of 34 states, which aims to coordinate economic and social policies. It was founded in 1960 and it is headquartered at Château de la Muette in Paris, France.

It has hosted international meetings in its paneled rooms designed to hold large conferences.

The importance of the events held at its facilities demanded a very high acoustic comfort. The movable acoustic walls reinforce the results of acoustic attenuation due to the absorption cameras it also enjoys, which endow the space for optimum levels of comfort by reducing echo.
