In this chapter we shall illustrate the main acoustic characteristics of closed environments. The contributing factors to the quality of the acoustics in an environment are numerous, and, once again, knowledge and experience are essential tools when it comes to projecting an acoustic space.
The most common type of space for us to picture is a room. A room of fixed, unchanging dimensions. Let's start to have a look at its acoustic characteristics. Depending on the material the walls are made of we will have more or less absorption and reflection of acoustic energy.
