Room Acoustics (also known as Architectural Acoustics or Building Acoustics) involves the scientific understanding of how to achieve a good sound quality within a building. The main purpose of this paper is to build a Room Acoustics Simulation which is capable to: demonstrate visualization of sound propagation around 3-D virtual room environment, examine the Room Impulse Response (RIR) and perform a less computational cost audio demonstration to understand the behavior of reverberation and echo effect. Furthermore, this paper proposes a new method to obtain the RIR for a given receiver point. In this paper, Image-Source Method (ISM) use as a modeling method for this acoustic simulation. Since all the previous works about ISM are done for 2-D room environments, this paper could be the first to implement ISM for 3-D virtual room environment.
