An Introduction to Acoustics

A short introduction to room acoustics

Sound waves are mechanical waves and the behaviours of fixtures inside rooms are governed by rules in physics. These fixtures are classified into three groups: reflectors, diffusers and absorbers, and the physical properties are investigated. The important parameters in determining acoustic quality of rooms are introduced. On the other hand, it is shown that limitations exist on applying these ...
