Acoustics and Noise Control

Overview

Research in this theme aims to integrate engineering and perceptual approaches to the solution of acoustic problems in the built environment.

Studies have shown that engineering noise control solutions are not sufficient for dealing with today’s acoustical challenges, as multiple factors affect sound and its perception. The research focus of the acoustics theme is therefore in line with the broader soundscape approach, which relies on both physical characteristics and mental perception of the aural environment. Soundscape research is multidisciplinary by nature, as it combines engineering and social science methodologies, in view of developing qualitative solutions aimed at improving quality of life and comfort. An example of research recently carried out is given by the acoustical and perceptual analysis of water generated sounds for road traffic noise masking.

Alongside soundscape research, we have expertise in sound transmission through buildings and, in particular, mathematical models which can predict the performance of entire buildings, as well as classroom acoustics and hospital noise research. Our main areas of interest include:

• Soundscapes of the Built Environment
• Environmental Noise
• Building Acoustics
• Room Acoustics

Facilities

The School of Energy, Geoscience, Infrastructure and Society has excellent facilities in acoustics. The specialised laboratories of the School include an anechoic and reverberant chamber, and horizontal and vertical sound transmission suites. This is supported by a wide range of equipment and instrumentation. A variety of test procedures can be carried out in our facilities, which are available for hire.
