DESC9090: Audio Systems and Measurement

Semester 2, 2023 [Normal evening] - Camperdown/Darlington, Sydney

Students will learn to make and understand a wide range of acoustical and electroacoustical measurements, assessed through laboratory or field work, and learn major aspects of sound system design, assessed through project work. Students will work in small groups in laboratory or field project work. Audio Systems and Measurement will develop knowledge and practical skills in electroacoustics; and the laboratory and project work will extend thinking and personal skills, so that students can apply the unit content to new situations. Upon completing Audio Systems and Measurement, students will be expected to understand the signal-processing basis, implementation and limitations of a wide range of audio and acoustical measurement techniques, such as sound pressure, linear time-invariant system response, source directivity, non-linear distortion, time variance, uncertainty in measurement, intelligibility, and audio quality. Students will also be expected to be able to design sound reinforcement systems, and to model audio system performance using various theoretical techniques.

Assessment summary

This unit of study has two assessments, which are broken into stages.

In the first half of the semester we will be mostly focusing on design, and so you will mainly work on the Audio System Modelling with EASE assignment. The final due date of this assignment is Friday 29/09/23, and smaller tasks contributing to the assignment will have due dates provided via Canvas. The assignment contributes 40% of the unit of study mark.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2021 (Schedule 1).

Credit

65 - 74

To be awarded to students who, in their performance in assessment tasks, demonstrate the learning outcomes for the unit at a good standard as defined by grade descriptors or exemplars established by the faculty.

Pass

50 - 64

To be awarded to students who, in their performance in assessment tasks, demonstrate the learning outcomes for the unit at an acceptable standard as defined by grade descriptors or exemplars established by the faculty.

Fail

0 - 49

To be awarded to students who, in their performance in assessment tasks, fail to demonstrate the learning outcomes for the unit at an acceptable standard established by the faculty.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

This unit has an exception to the standard University policy or supplementary information has been provided by the unit coordinator. This information is displayed below:

Academic integrity

The Current Student website  provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.  

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

  • LO1. identify and understand concepts underlying current measurement methods used in audio systems
  • LO2. make measurements, analyse, and interpret results in relation to performance criteria
  • LO3. design an effective audio system in a room, using a combination of theory and software-based modelling techniques.

Graduate qualities

The graduate qualities are the qualities and skills that all University of Sydney graduates must demonstrate on successful completion of an award course. As a future Sydney graduate, the set of qualities have been designed to equip you for the contemporary world.

GQ1 Depth of disciplinary expertise

Deep disciplinary expertise is the ability to integrate and rigorously apply knowledge, understanding and skills of a recognised discipline defined by scholarly activity, as well as familiarity with evolving practice of the discipline.
