Description

This unit provides an introduction to acoustics, including the theoretical background and applications in areas of architecture, fluid mechanics and aerospace. Students will be introduced to the main concepts and governing equations in acoustics and will learn how to analyse and explain sound behaviour in free-field and bounded environments.

The aims of this unit are:

1) To introduce students to the important acoustical concepts and definitions

2) To acquaint students with the mathematical and physical principals that underpin the behaviour of sound in different environments

To enable students to apply that knowledge to real-world tasks

Intended learning outcomes

Having successfully completed the module, the students will be able to:

1) Describe and explain the acoustic metrics: noise level, combing noise sources coherent and incoherent

2) Derive and solve the wave equation in different media and coordinate systems

3) Solve and explain acoustic radiation and scattering

4) Solve and explain acoustic reflection, transmission, refraction and absorption

5) Explain acoustics of cavities and waveguides through derivation and solution of underlying equations

6) Describe architectural acoustics: room modes, sound isolation, reverberation,

Describe aeroacoustics: Jet noise, airframe noise, boundary layer noise

Teaching details

This is a 22-hour lecture-based course - 22 x 1-hour lectures each week for approximately 12 weeks

In addition, students are expected to consolidate and enhance the lecture material by approximately 75 hours of private study. Handouts and extra reading material are given throughout the course. Examples are given, covering a range of engineering applications.

Computer presentations and videos will be used as part of the delivery vehicles.

Assessment Details

100% 2-hour Examination
