![]() | 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. |
