The Laboratoire d'Expériences du Bureau (LEB) is designed as an experimental, educational and experiential space for workspace designers. Its purpose is to provide a better understanding of the implications of design choices on the likely sound experience of people at work. Equipped with a set of mobile acoustic devices, an sound ambience generator software and a multi-channel sound system, it reproduces a range of sound phenomena and immerses listeners in a range of sound ambiences in a work situation. Users are helped to gradually become aware, through sound experience, of the implications of their design choices. The process is part of a research approach to the design of sound devices based on the ideation of new paradigms and modelling hypotheses. This article intends to present the key concepts of the project, how it differs from other comparable approaches, its state of progress as well as the limits and difficulties encountered. In 1989, the French office furniture manufacturer CLEN introduced the concept of the Office Space Laboratory, a workspace dedicated to experimentation in situ, at its factory in Saint-Benoit-La-Forêt in Touraine. Since 2000, CLEN has increasingly designed and manufactured acoustic products, notably through its subsidiary Manade, and has faced growing challenges in providing relevant answers to the complex questions posed by managing the auditory experience at work. Since then, this field has become extremely competitive, while the solutions proposed often remain debatable. At best, they conform to current standards, which, even though they have recently progressed towards better alignment with activities, are not always well understood. In 2020, the CLEN Group partnered with the CRD ENSCi -ENS Paris-Saclay to create the [S'entendre] Chair, a collaborative research framework in experience design for shared workspaces, with the aim of designing and modelling alternative approaches to improve the "sound experience" 4 experience at work. Among other exploratory research and development efforts, we have designed and modelled an Acoustic Workshop in the new LEB premises in Rueil Malmaison. This project and the questions it raises are the subject matter of this article.
