Materials for calibrating coupled-volume virtual opera houses through acoustic simulations

The present repository provides the necessary data to perform the acoustic simulation of two virtual opera houses: Bonci theatre (hall B) in Cesena (Italy); Alighieri theatre (hall C) in Ravenna (Italy). This material is intended to complete and extend the data provided in doi.org/10.17632/y7xnv6xg5s (hall A=TCB, hall D=DUS). Folders contain the 3D virtual models (SketchUp 2019), the main results of acoustic measurements (Room criteria in octave bands according to IS0 3382), the boundary conditions for FDTD code (normalized LRC coefficients employed as input data in FDTD simulations to approximate frequency-dependent boundary admittances), the corresponding energy parameters employed in GA++ simulations (absorption and scattering coefficients), and finally the simulated impulse responses through FDTD techniques.本数据集仓库提供了两座虚拟歌剧院开展声学仿真所需的全部数据：分别为意大利切塞纳的邦齐剧院（B厅），以及意大利拉文纳的阿利盖里剧院（C厅）。本数据集旨在补充并拓展doi.org/10.17632/y7xnv6xg5s中已公开的相关数据（其中A厅对应TCB，D厅对应DUS）。数据集文件夹包含以下内容：基于SketchUp 2019制作的三维虚拟模型；声学测量的核心结果（依据ISO 3382标准在倍频程频段下的厅堂声学评价指标）；用于时域有限差分（Finite-Difference Time-Domain，FDTD）仿真的边界条件参数（归一化LRC系数，作为FDTD仿真的输入数据，用于近似频变边界导纳）；用于GA++仿真的对应能量参数（吸声系数与散射系数）；以及通过FDTD技术生成的仿真脉冲响应。
