Image-source room acoustics modelling becomes computationally costly in interactive VR

Evidence

Room effect simulation. The image–source-method, discussed in Section 2.4.5, is, in principle, a feasible method to simulate the room effect in virtual reality. The positions of image sources can be computed, and they can be reproduced by applying the appropriate direction in virtual source positioning, as above. The delay and gain for sounds of image sources are specified by their geometric location in the virtual world. However, such accurate modelling often leads to computationally complex solutions. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 2567
