Outline

Overview

This unit introduces the fundamental concepts and issues of audio and architectural acoustics, with an emphasis on theory. The unit introduces topics such as: basic acoustical concepts, quantities and units; principles of sound radiation and propagation; sound absorption and room acoustics; psychological acoustics; noise measurement and specification; speech intelligibility; and principles and specification of airborne sound insulation. Acoustics theory involves mathematics, and this unit aims to provide knowledge and skills so that such theory can be applied, with the help of spreadsheets and computer programs. Teaching is supported by demonstrations and tutorials. By completing this unit students will be able to understand acoustical terminology, and perform calculations and analysis applicable to sound in the environment, in buildings, and in audio contexts. They will have the ability to critically assess claims of acoustical performance. This unit provides the theoretical foundation for advanced units in audio and acoustics.

Assessment summary

Assessments in this unit of study are exercise-based assignments.

Marks are assigned to each question, and the marks are summed to yield the total.

Some questions are mainly calculation-based. However it is important to demonstrate an understanding of the calculation (e.g., what it means, what it implies, how it compares to expectations, etc).

Some questions are mainly analysis-based. Again, it is important to demonstrate an understanding of the analysis. A description is not an analysis.

Some questions are based on a review of scientific literature. Intelligent use of high quality sources, development and interpretation of concepts, application to the specific issues in the question, etc, are among the important features of a good answer.

Assignment 1 is weighted 30%, and assesses concepts up to and including ‘Room Acoustics’ (learning outcomes 1-7).

Assignment 2 is weighted 70%, and assesses concepts over most of the semester (learning outcomes 1-10).

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a High distinction indicates work of an exceptional standard, a Distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Result name	Mark range	Description
High distinction	85 - 100	Work of outstanding quality, demonstrating mastery of the learning outcomes assessed. The work shows significant innovation, experimentation, critical analysis, synthesis, insight, creativity, and/or exceptional skill.
Distinction	75 - 84	Work of excellent quality, demonstrating a sound grasp of the learning outcomes assessed. The work shows innovation, experimentation, critical analysis, synthesis, insight, creativity, and/or superior skill.
Credit	65 - 74	Work of good quality, demonstrating more than satisfactory achievement of the learning outcomes assessed, or work of excellent quality for a majority of the learning outcomes assessed.
Pass	50 - 64	Work demonstrating satisfactory achievement of the learning outcomes assessed.
Fail	0 - 49	Work that does not demonstrate satisfactory achievement of one or more of the learning outcomes assessed.

For more information see guide to grades.

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:

Late penalties follow Sydney School of Architecture, Design and Planning policy (https://www.sydney.edu.au/handbooks/architecture/rules/faculty_resolutions.shtml): (1) It is expected that unless a simple extension, special consideration or disability adjustment has been granted, students will submit all assessment items for a unit of study on the due dates specified. If an assessment is submitted or otherwise completed within a period of extension granted by successful application for simple extension, special consideration or an assessment adjustment determined by Disability Services, no academic penalty will be applied to that piece of assessment. (2) If an extension is not sought, not granted, or is granted but work is submitted after the extended due date, the late submission of assessment will result in an academic penalty as follows: (a) For non-public assessments, work submitted after the deadline will incur a penalty of 5% of the total marks earned for the assessment per calendar day. Work submitted 20 calendar days or more after the deadline will not be assessed and will receive a mark of zero. (b) For assessments involving public, oral, and/or visual presentations completed after the deadline, a penalty of 10% of the total marks earned for the assessment will be imposed per calendar day. Work completed 10 calendar days or more after the deadline will not be assessed and will receive a mark of zero.

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.

Use of generative artificial intelligence (AI) and automated writing tools

You may only use generative AI and automated writing tools in assessment tasks if you are permitted to by your unit coordinator. If you do use these tools, you must acknowledge this in your work, either in a footnote or an acknowledgement section. The assessment instructions or unit outline will give guidance of the types of tools that are permitted and how the tools should be used.

Your final submitted work must be your own, original work. You must acknowledge any use of generative AI tools that have been used in the assessment, and any material that forms part of your submission must be appropriately referenced. For guidance on how to acknowledge the use of AI, please refer to the AI in Education Canvas site.

The unapproved use of these tools or unacknowledged use will be considered a breach of the Academic Integrity Policy and penalties may apply.

Studiosity is permitted unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission as detailed on the Learning Hub’s Canvas page.

Outside assessment tasks, generative AI tools may be used to support your learning. The AI in Education Canvas site contains a number of productive ways that students are using AI to improve their learning.

Learning support

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.
