Abstract
Finite difference time domain (FDTD) methods are applied for low frequency numerical analysis of Dizzy’s Club Coca-Cola. The FDTD simulation is constructed from a 13-point stencil face-centered cubic grid with a one centimeter grid resolution. The geometrical acoustic analysis is computed using commercially available software. Each impulse is combined at varying crossover frequencies ranging from 50 Hz to 1 kHz, giving a total of 14 hybrid room impulse responses. The evaluation of each hybrid impulse response consists of the physical comparison between calculated hybrid and measured room acoustic parameters. Direct-to-reverberant energy ratio, early-to-late energy ratios, and reverberation times are used for the physical comparison to assess the accuracy and plausibility of each hybrid room impulse response.
