Building Acoustics and Noise Control

Building Acoustics and Noise Control

This course is aimed at anyone considering entering the acoustic consultancy profession including university students, engineering and architectural professionals looking for a career change or construction industry contractors. It provides the fundamental knowledge to understand the key design aspects of building acoustics and noise control. It is considered to be entry level acoustics knowledge for all engineering students wanting to get a job in the acoustic industry. High school mathematics is preferred but not essential.

To demonstrate the concepts, example spreadsheet calculations and sound demonstrations (called auralisations) are provided. Spreadsheets are also available as separate downloads.

Topics covered include acoustic fundamentals, sound outdoors, room acoustics, sound insulation, impact noise, acoustics for sustainable design.

By the end of this course students with an undergraduate degree in engineering, science or architecture, as well as mature age students with previous work experience from the building and construction industry will have enough background knowledge to qualify for entry level acoustic consultant job positions.
