In this paper, a modification of the diffusion model for room acoustics is proposed to account for sound transmission between two rooms, a source room and an adjacent room, which are coupled through a partition wall. A system of two diffusion equations, one for each room, together with a set of two boundary conditions, one for the partition wall and one for(More)
In the framework of the design process of a multimodal 3D simulation environment to support architects' acoustic tasks, we wanted to gain a better understanding of how architects are able to discriminate the sounds using audio and/or visual inputs. This study explores how 2D pictures of rooms do support or impede the auditory evaluation of a space(More)
In the context of the design of a multimodal environment for room acoustics evaluation, we investigate the link between a projected image and the sound of an acoustic simulation. 54 subjects have been tasked to judge the level of reverberation of a sound in a control situation (without image) and in an experimental situation. In this experimental condition,(More)
