| Outcomes |
Students are able to explain the principles of sound generation and propagation, its detection and measurement by microphones, its amplification and modification through amplifiers/filters and software, and its reproduction through speakers and headphones. They are able to synthesise, measure, manipulate and generate sounds and similar time waveforms using current computer software, and understand the pitfalls in these processes. They can also explain key issues in evoked response testing of ears and architectural acoustics. |
| Content |
This unit is taken over two successive semesters and parts 1 and 2 must be completed sequentially to fulfil the requirements of the unit.
The unit provides a comprehensive coverage of the physical principles of sound generation and audiological measurements. Topics covered include the physics of sound, waves and their time-domain and frequency-domain analysis, Fourier or spectral analysis, decibel scales, sound pressure measurements, microphones, loudspeakers, headphones, frequency response and sound pressure calibration, noise measurement, weighting scales and band-analysis, equal loudness contours, physics of sound source localisation, basic architectural acoustics, echo and reverberation, basic electronics, sampling, quantisation and aliasing, digital filtering, complex signal processing, basic audiometer design, noise analysis, evoked response and otoacoustic emission technology, and foundations of hearing aid design and implant technology. |
| Assessment |
This comprises laboratory reports and other continuous assessment (20 per cent) and two theory examinations at the end of each of semesters one and two (80 per cent).
Supplementary assessment is available for those students who obtain a mark of 45 to 49 inclusive in this unit (see University General Rule 1.2.1.25). |

- The availability of units in Semester 1, 2, etc. was correct at the time of going to press but may be subject to change.
- Assistance with study skills, including English language skills, is available free of charge from Student Services for all enrolled students (see http://www.studentservices.uwa.edu.au/ss/learning). Student Services location: Second Floor, South Wing, Guild Village; telephone: 6488 2423.
- Books and other materials wherever listed may be subject to change. Book lists relating to 'Preliminary Reading', 'Recommended Reading' and 'Textbooks' are, in most cases, available at the University Co-operative Bookshop (from early January) and appropriate administrative offices for students to consult. For first-year units the Bookshop will endeavour to make available photocopies of book lists for individual units. Books marked with an asterisk (*) are available in paperback.
