Acoustical engineering is the branch of engineering dealing with sound and vibration. It is closely related to acoustics, the science of sound and vibration. Acoustical engineers are typically concerned with:
how to reduce unwanted sounds
how to make useful sounds
using sound as an indication of some other physical property
The art of reducing unwanted sounds is called noise control. Noise control engineers work with engineers in most industries to ensure that their products and processes are quiet. There is also a great deal of work done with the assessment and design of buildings, workplaces, airports, road systems in fact most noise generating or noise sensitive developments. There are many standards and documents stating what levels of performance must be achieved for each condition. The various standards and regulations used in the UK are condensed into The Little Red Book of Acoustics.
