This module is intended to provide an understanding of the important considerations in the acoustic design and improvement of recording studio spaces. Much of the work will involve mathematical calculations and equations essential for understanding the acoustics in a methodical manner. Spreadsheet software will be introduced for the purpose of assisting the design process and this forms a major part of the module. Practical workshops relating to prediction, measurement and processing will also be a key part of the module. The teaching structure will also include a visit to an acoustics research facility and a guest lecture by a studio design professional.
