Content
Covering the principles, concepts and practical applications of current noise control technology, this comprehensive unit is designed for students who want to learn reliable, straightforward and practical methods to deal with industrial and environmental noise. Among the topics covered are the following: noise criteria, masking, speech interference and hearing damage; microphone calibration, instrumentation and its uses; noise sources, sound radiation, sound power measurement and source directivity; sound fields in enclosed spaces and reverberation control; noise barriers and transmission loss; small engine mufflers and side branch resonators, vibration control and isolation for noise control. Students are able to apply their knowledge of applied acoustics for two laboratory practices and other practical noise analysis and control. This unit is of interest to those considering a career as acoustical and noise control consultants, practicing engineers, architects and all other professionals concerned with noise abatement and control.
Outcomes
Students are able to (1) explain the principles of applied acoustics; (2) understand the effect of noise on humans; (3) undertake noise assessment and measurement; (4) determine sound power and directivity of noise sources; (5) evaluate and control sound quality in enclosures; (6) design of noise barriers and partitions; (7) design small engine mufflers and side branch resonators; (8) implement vibration control and isolation for noise control; (9) work effectively in a diverse team to achieve professional outcomes; and (10) communicate effectively through concise written technical reports.
Assessment
Typically this unit is assessed in the following ways: (1) assignments; (2) laboratories; and (3) final examination. Further information is available in the unit outline.

Supplementary assessment is only available in this unit in the case of a student who has obtained a mark of 45 to 49 and is currently enrolled in this unit, and it is the only remaining unit that the student must pass in order to complete their course.

  • 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.
