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.
Outcomes Students are able to (1) 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; (2) synthesise, measure, manipulate and generate sounds and similar time waveforms using current computer software, and understand the pitfalls in these processes; and (3) explain key issues in evoked response testing of ears and architectural acoustics.
Assessment Typically this unit is assessed in the following ways: (1) laboratory reports and other continuous assessment (20 per cent) and (2) two theory examinations at the end of each of semester 1 and semester 2 (80 per cent). Further information is available in the unit outline.

Supplementary assessment is not available in this unit.

Unit notebooks and laboratory manuals are produced for the unit.

  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Books and other material 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. Where texts are listed in the unit description above, an asterisk (*) indicates that the book is available in paperback.
