Different sound decay patterns and energy feedback in coupled volumes

Abstract: Different non-exponential decays such as the concave and the convex double sloped decays in the coupled rooms provide distinct sound qualities. These are commonly considered to occur in the less reverberant sub-room and the more reverberant sub-room, respectively. However, numerical simulations and experiments in this paper show that the demarcation line is not located along the physical boundaries (e.g., the partition and the coupling aperture), but in the more reverberant sub-room. The sound field with the c… Show more

“…However, the bedroom and the living room formed a coupled system when the partitions were removed. Acoustically coupled spaces could have properties different from those of these spaces when they were uncoupled [13]. The furniture adopted in this study consisted of a bed and a sofa (Fig.…”

“…Bayesian methods have been utilized in a wide range of acoustics applications [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] with increasing attention being given to the task of performing Bayesian model selection. A few of the most recent applications of Bayesian model selection can be found in such acoustics applications as roomacoustics energy decay analysis 1 and geo-acoustics inversion, 2,3 where the model selection problems are tackled separately from that of parameter estimation.…”
