ABSTRACT
This chapter presents a basic understanding of how sound reacts with certain materials and discusses problems and solutions for many misunderstood creations, and the placement of the sound equipment. When a specific frequency resonates in a particular cavity, that sound is perceived as being more intense than all of the other frequencies being produced. A space, such as a small control room or the body of an acoustic guitar, will resonate at a certain frequency dependent on the size of the area. An occurrence that is still fairly new to acoustic design and is continually being re-invented is diffusion. Unlike reflection, diffusion disperses the waveform evenly into the room. Before a space is examined and tested to determine its specific acoustical needs, speaker placement must be addressed and optimized. If the speakers are in the center of a rectangular room, the distribution of sound can be easily determined and further decisions for acoustical structures can be optimized.
