Evaluation of the acoustic properties a performance area.

Sound is described as a "mechanical compression and rarefaction or a longitudinal displacement wave that propagates through a medium (solid, liquid or gas)" (source www.mywiseowl.com). Put into simpler terms this means that sound is caused when an object vibrates, causing changes in pressure within a medium. For example when a speaker cone vibrates in a room the movement of the cone causes the air particles close to it to move in the same way. These moving air particles now bump into the air molecules next to them transferring energy and making them move in correspondence with the speaker cone, this process repeats again and again and the sound wave moves further away from the source. The further away the sound wave moves the less energy there is to be transferred between air particles due to absorption or the dissipation of energy hence the sound is quieter the further away the listener is from the original sound source.......
