Module Overview

This module is intended to provide you with a solid grounding in electro-acoustics with emphasis on  the  study  of  loudspeakers  and  microphones  including  use  of  single  degree  of  freedom modelling.

Prerequisites/Co-requisites

Level 4 Acoustics and Computer Audio Systems A and B

Level 4 Audio Engineering and Recording Techniques A and B

Level 4 Electronics and Audio Signal Processing A and B

Module Aims

This module aims to:
 
• 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

Learning Outcomes

On successful completion of this module, you should be able to:
 
1. describe the principles of operation of pressure, pressure gradient, combination, and
highly directional microphones (C, K)
2. describe the design of condenser, moving coil, and ribbon microphones. (C, K)
3. describe and explain microphone specifications. (C, K, P)
4. mathematically describe the performance of a variety of microphones (C, K)
5. use mathematical modelling to investigate the effect of changing an aspect of
microphone design (C, K,)
6. describe the transduction mechanisms found in loudspeakers. (C, K)
7. describe the operating principles of moving coil, electrostatic, ribbon and horn
loudspeakers. (C, K)
8. discuss the performance limitations of typical loudspeaker designs. (C, K, P)
9. mathematically describe the performance of a loudspeaker unit. (C, K)
 
In addition, you will have demonstrated the following professional and transferable skills:
 
Problem solving (T, P)
Report writing (T, P)
 
Key: C-Cognitive/Analytical; K-Subject Knowledge; T-Transferable Skills; P- Professional/
Practical skills

Module Content

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.
  • Microphone specifications.

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
 
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.
 
Summative Assessment
 
• 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
 
Formative assessment is provided though coursework feedback
 
Feedback
 
You will receive written feedback on your coursework
