- Deriving mathematical expressions for microphone and loudspeaker behaviour
- Calculation of loudspeaker and microphone characteristics from physical parameters
- Transduction mechanisms in loudspeakers
- Operating principles of moving coil, electrostatic, ribbon and horn loudspeakers

- Principles of operation of pressure, pressure gradient, combination, condenser, moving coil, and ribbon microphones.
- Microphone specifications.
|Assessment type||Unit of assessment||Weighting|
|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 assessments based on microphones (addresses learning outcomes 1-5) and loudspeakers (addresses learning outcomes 6-10); and
- 2-hour examination - a written paper given under exam conditions (addresses learning outcomes 1-9).
There are no formal formative assessment components for this module, but formative feedback will be given to you in tutorials and throughout seminar and practical workshops, and in the form of regular revision questions in lectures.
Written feedback will be given on the coursework assignments. You will receive verbal feedback on your practical work throughout the module, particularly in seminars and practical workshops, and in the form of regular revision questions in lectures.
- 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

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 Level 4 Recording Techniques.
The learning and teaching methods include:
- 22 two-hour lectures
- 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.
