Room acoustics simulation is used in the audio industry for designing rooms, evaluating acoustic treatments, determining optimal placement of speakers and microphones, and auralization. Due to the wavelength and size scales, it is difficult to accurately model the room’s response over the entire frequency range. This presentation will focus on using a hybrid approach, where the results from multiple numerical methods are implemented into a single model, thereby improving accuracy and maintaining feasibility. This presentation will include detailed discussion about finite element modeling, ray tracing, appropriate source conditions, and boundary conditions. Results from the model are compared to measurements of Acentech’s Founders Room Listening Lab in Cambridge, MA.
