ISVR6145 Acoustics III

Module Overview

Acoustics 3 builds on the basic elements of acoustics covered in the core modules Acoustics 1 and 2, by introducing more advanced topics in theoretical acoustics. The focus will be on modelling sound fields generated by complex source distributions, including sound in enclosures and ducts. More sophisticated analytical methods will be introduced, including the acoustic Green function and integral solutions of the acoustic wave equation.

Aims and Objectives

Module Aims

• Understand how basic elements of acoustics theory can be extended to study more complex problems associated with sound generation and radiation. • Formulate analytical models for theoretical acoustics. • Solve examples of practical problems in physical acoustics. • Recognise more advanced techniques used in theoretical acoustics, and gain insight into concepts which would be studied more rigorously at graduate-level courses in acoustics.

Learning and Teaching

Teaching and learning methods

The course will be delivered using a mixture of lectures, typically two per week, and tutorials to cover the application of the material to example problems. A structured coursework exercise which will include theoretical analysis, numerical computation, and critical evaluation of the results, is included in the teaching and learning experience.
