Abstract
This paper focuses on the matter of sound propagation in various indoor spaces by means of the Ray-Tracing method. Nowadays, this is an issue that is often encountered both in the academic environment and in real-life situations, being present in fields such as acoustic engineering. This research study provides an acoustic model meant to support engineers in the proper construction, by careful consideration of the acoustics in various indoor spaces such as amphitheaters, concert halls, churches, mosques, factories and many more. Moreover, this recommended model for efficiency comes as a long awaited development for people to be able to listen to sounds produced at a higher quality level. A number of different experiments have been carried out to determine suitable parameters such as the most suitable construction material for the walls of the room, the maximum sound frequency, the dimensions of the room and other factors equally important.
