A general approach to investigate the problems associated with residential noise issues is described. This research combines knowledge of the evolving nature of the governmental legislation used to control the finished quality of modularly constructed building products with small scale laboratory testing, full scale on-site testing, and surveys performed on a population sample resident in modularly constructed dwellings. Due to the time and expense associated with full scale testing of every possible design, the clear need for the development of a reliable and accurate method to predict the acoustics performance of building elements has been explored. Laboratory experimental work has yielded results that correspond well with that of large scale on-site testing. The results obtained have been vigorously examined in an attempt to understand the factors and parameters involved in the sound transmission through building elements. An attempt to simulate the test environment of reverberation chambers has been made, through the development of a mathematical model that predicts and assesses the acoustic behaviour of potential partition designs exposed to airborne sound, therefore reducing the need to constmct and test small or large scale prototypes. Approximation methods have been investigated and found to accurately resemble test data within certain parameters. Limitations as to this type of methodology have been discussed. Issues allied with the complexity of assessing the acoustic performance of various building methods have been considered and reviewed. A survey on a population sample has highlighted and characterised frequencies associated with perceived noise annoyance within the modular construction industry, and this work has been found to be in good agreement with other works in this field, further contributing to the continued understanding of the need for a method of determining acoustic performance by a single figure rating.
