Part of programme
The course aims at presenting the fundamental ideas and theories necessary to understand and analyse elastic wave phenomena in fluid or solid media. The course also gives an introduction to signal analysis and measurement techniques as well as human reponse to sound and vibration. The goal is to give the student a good understanding of the theory and illustrate important applications ranging from design of consert halls to quite vehicles and low noise fans.
After the course students should be able to:
- Describe fundamental concepts of engineering noise and vibration, measurement techniques and instruments. Explain the effect of noise and vibrations on humans and equipment.
- Apply Fourier analysis to solve coupled differential equations, calculate the frequency content of periodic and transient signals and implement this knowledge to analyse mechanical systems. Describe methods to distinguish between linear and non-linear mechanical systems.
- Understand the physical foundations and the mathematical models of sound waves in fluids and solids, wave propagation, transmission, reflection and radiation and understand how to apply these models to sound and vibration problems in mechanical and vehicle engineering.
