In order to achieve accurate acoustic simulations of a room for obtaining an authentic auralization, the following aspects need to be quantified: the geometrical details of the room, all material properties and the characteristics of the source and the receiver. This paper presents the design of a benchmark room for this purpose, including all this information. The room is a building acoustics transmission chamber with thick concrete walls. This room was then acoustically treated to achieve an acoustic environment close to a day-to-day office room. The surface impedances of the materials additionally installed in the room were measured with both in the impedance tube as well as with a pressure-velocity sensor. Furthermore, the directivity of the measurement source and the binaural receiver were measured in order to be included in the simulations. Impulse responses of this benchmark room have also been obtained from simulations with the in-house time-domain discontinuous Galerkin method (DG) with frequencydependent boundary conditions, including source and receiver directivity. Time and frequency domain results from the both the measurements and simulations are presented, showing a close agreement.
