Brief Handbook Description: This unit of study should prepare the student to be able to undertake vibration and acoustic measurement calculations for industry design situations.

The unit aims to introduce a number of new concepts required for analysis of vibrations and acoustics. The response of structure under different dynamic forces, including human and aerodynamic, will be investigated. A number of hands-on experiments will be performed to allow an understanding of the concepts and applicability.

The acoustics component will include: basic acoustics theory, sound generation and propagation, impedance, absorbing materials, industrial noise sources, isolation methods of noise control, enclosures, instrumentation and measurement, frequency analysis, noise regulations and computational acoustics.
Assumed Knowledge: None.

Assessment Description: * indicates an assessment task which must be repeated if a student misses it due to special consideration

Hammer Testing Laboratory: Vibration suppression and experimental testing

Assignment: Further understanding of Vibration Theory

Acoustics Labs: Students will gain hands-on experience in acoustics measurement and testing.

Acoustics Project: Further understanding of Acoustic Theory. Peer assessment will be used to determine each student`s final mark.

Mid Semester Quiz - Multiple choice questions.

End of Semester Quiz - Computational exercise

The penalty for lateness is 5% per day. The penalty would apply from the next calendar day after the deadline.

The penalty is a percentage of the available mark and is applied to the mark gained after the submitted work is marked (e.g., an assignment worth 100 marks is 1 day late. The content is given a mark of 75. With the 5% penalty, the final mark is 70).
Assessment Feedback: Exercises and assistance will be provided during tutorial sessions.
Policies & Procedures: See the policies page of the faculty website at http://sydney.edu.au/engineering/student-policies/ for information regarding university policies and local provisions and procedures within the Faculty of Engineering and Information Technologies.
