Indicative content includes:
Use of the single degree of freedom model in electro-acoustic devices
Transduction mechanisms in loudspeakers.
Operating principles of moving coil, electrostatic, ribbon and horn loudspeakers.
Design of a loudspeaker using commercially available parts
Analysis of results of experimental data produced in class
Performance limitations of typical loudspeaker designs
Deriving mathematical expressions for microphone and loudspeaker behaviour
Calculation of loudspeaker and microphone characteristics from physical parameters
Principles of operation of pressure, pressure gradient, combination, and highly directional microphones.
The design of condenser, moving coil, and ribbon microphones.
|Assessment type||Unit of assessment||Weighting|
|Coursework||COURSEWORK 1: LOUDSPEAKERS||33|
|Coursework||COURSEWORK 2: MICROPHONES||17|
|Examination||EXAMINATION (2 HOURS)||50|
The assessment strategy is designed to provide you with the opportunity to demonstrate academic writing skills, solution of calculation based problems, and application of theory to a design proposal.
• Two written coursework assignments based on Loudspeakers (addresses learning outcomes 6-9) and microphones (addresses learning outcomes 1-5)
• 2hr exam (addresses learning outcomes 1-9)
Formative assessment is provided though coursework feedback
You will receive written feedback on your coursework
- Familiarise you with the principles behind the operation of common transducers and how the alteration of various physical parameters will affect the performance characteristics of the device.
- Familiarise you with the use of single degree of freedom modelling

Lecture Hours: 36
Methods of Teaching / Learning
The learning and teaching strategy is designed to: deepen understanding of loudspeaker and microphone design following on from HE4 introduction in TON1017.
The learning and teaching methods include:
• A two hour lecture (loudspeakers) and a one hour lecture (microphones) each week
• A practical loudspeaker measurement session followed by report writing and results analysis
• Independent reading and research
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
