Learning outcomes
When you finish this unit, you should be able to:
- 1
Calculate basic noise measurement quantities (sound pressure levels, sound power levels and sound intensity level);
- 2
Model the propagation of sound in a duct and in free-space;
- 3
Analyse the fundamentals of reactive noise attenuation devices;
- 4
Explain the concept of transmission loss:
- 5
Explain the concepts of direct and reverberant noise field in a close-environment;
- 6
Combine the concepts of noise source, noise path and noise measurement to examine the impact of a given noise source on its environment.
