Follow this link for further information on unit content Description: Aims:
To introduce quantitative aspects of noise control and to give an appreciation of some of the problems involved.
To acquaint the student with more advanced aspects of vibration.

Learning Outcomes:
On successful completion of the unit the student will have:
* Calculated sound pressure level given relevant power and material data. Estimated the reduction in sound pressure level that could be achieved by the use of a barrier or enclosure.
* Used phase-plane plots and energy methods to analyse non-linear vibration problems.
* Applied harmonic balance to solve Rayleigh's equation to obtain limit cycle solutions and also to solve Duffing's equation and thus to explain jump phenomena.

Skills:
Problem solving; numeracy; working independently.

Content:
Response of the ear, noise exposure, code of practice; noise isolation and absorption; barriers and enclosures. Nonlinear vibration. Duffing's equation, Rayleigh's equation. Phase-plane plots. Topics for self study.
