![]() After running a ray tracing simulation, the locations of the first reflection points are visible as white bounces. In Fig.1, a studio control room has been modelled using EASE. Ray tracing can be used to find first reflection points between speakers and listener seats, and reverberation time simulation tells us if we are using the right amount and balance of acoustic treatment for a specific volume of space. ![]() For high end listening rooms and studios, we use EASE to plan the placement and amount of acoustic treatment. AFMG EASE is the industry standard simulation software for larger spaces, in part due to its comprehensive database of loudspeaker manufacturers and acoustic materials. While acoustic simulation has more uses for larger spaces, it can also be deployed in small room design as long as its limitations are understood. In this last and final part, we will focus on the software and hardware tools required to design, install and optimize a “small” room and audio system. While this is by no means a comprehensive list of acoustic and audio topics, it hopefully demonstrates a more practical approach to design, highlighting theory only when its understanding is absolutely vital to your design approach. Parts 4 and 5 covered system design goals and finally how to optimize a system. We continued onto sound isolation, absorption and diffusion in parts 2 and 3. We started this series with the definition of a small room, and went on to discuss wave interactions.
