Abstract

This paper reports the multidisciplinary approach applied for the design of a new conference room in Switzerland. This conference rooms belongs to a large new educational building realized in Delémont (CH) in 2016. The architectural approach focused on the choice of the room’s shape and materials (mainly timber) while the acoustic treatments had to provide a good insulation from exterior and adjacent rooms as well as a good intelligibility, clarity and speech definition. Simulations run with the software Odeon allowed to foresee the main acoustic indicators (T30, EDT, C80, D50, and STI) and therefore to optimize the dimension and position of the acoustic treatments for different occupancy rate. Moreover, the acoustic treatment enforced the vocal emission of the speaker without amplification systems. A measurement campaign at the end of the building construction confirmed the good acoustic quality of the conference room as well as some discrepancies with the forward analysis due to some changes during construction. The results of a survey are also reported in this paper in order to better understand the actual acoustic feeling of the users.
