抄録（英）
Though edge tone and aeolian tone are both treated as excited sounds from blocks, they are often to be done by different approaches to numerical analyses because an edge tone only has feedback loop caused by sound waves. In experimental apparatus, however, these phenomena can be generated simultaneously. Therefore, we have constructed the new soundproof room made by sound arresting walls considering of TV studio, in order to study the transition from edge tone to aeolian tone. As a numerical approach, Finite Difference Lattice Boltzmann Method (FDLBM), which is authorized as generalized numerical analysis, is also applied for evaluating the effect of the gas species in the transition.
