| 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. |

Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.
(6) Communication and Inquiry/ Research (Level 3)
1. Construct simple computer algorithms that will allow more complex geometries to be solved
2. Write an engineering report on an experimental test
3. Present results of an experiment to a peer audience
(7) Project and Team Skills (Level 3)
4. To work effectively in a team to complete a project
5. The students will manage their group project/assignments
(8) Professional Effectiveness and Ethical Conduct (Level 2)
6. Apply a solution to a standard problem
(4) Design (Level 4)
7. Understand the limitations of theory
(2) Engineering/ IT Specialisation (Level 4)
8. Predict the response characteristics of a structure under excitation
9. Extrapolate result to predict complete structural behaviours
10. Appreciate the social, economic, and legislative aspects of environmental noise. They will be able to make the calculations and measurements necessary to estimate sound levels and noise in machinery, buildings and the outside environment; and to make recommendations as to how best to reduce them.
(1) Maths/ Science Methods and Tools (Level 4)
11. Undertake experiments and analyse data to verify theoretical predictions
12. Improved understanding of the use of software packages to solve vibration problems

| 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). |
