Figure 1. Graphs comparing the proposed method and conventional methods’ predicted sound pressure level for a small cubic room to the reference values.

Caption

The proposed method is more consistent with the reference than the conventional method. Using 1/7 of the conventional method’s required memory, it can perform calculations 76% faster.
