Good sound is something most planners take for granted . . . until they experience bad sound. This class will discuss all the components of a good sound system, including all types of microphones, different types and locations of speakers, mixing boards, amplifiers, etc. We will cover the different personnel needs for a good audio system. In addition, we will discuss factors that impact acoustics, and how different types of output (e.g. speeches vs. music) will have different sound requirements.
