The essence of the acoustics and the sound system design is computer simulation and 3D modeling technique.
Predicting the performance of the acoustical material and audio equipment is done by sophisticated CAD software this is the most modern techniques available in the world for Acoustics and Audio Industry. This allows the prediction of proper speech and sound levels much before the construction of the building starts at the site.
The fine-tuning of the building acoustics is done in the 3D computer model (of each dome of the temple building) and its sound characteristics, thus, potentially, saving time and money on expensive remedial treatments that may otherwise have been necessary following project completion.
First a 3D wireframe model is prepared material on each surface is applied on the scaled model. The loudspeaker system is placed in the model in the X, Y and Z coordinates. The audience area is defined and then fine tuning of material and loudspeaker system firing angle is adjusted to get the best results.
The 3D model then is imported in a mapping module of the software, then ray tracing and mapping is done to adjudge the final performance of the acoustics and audio system.
