Members of the Acoustics Research Group have expertise in environmental noise, acoustical measurement techniques and musical acoustics.
Environmental acoustics research carried out by the group includes work on improving the prediction of sound propagation outdoors, producing more effective noise barriers, increasing understanding of acoustic-to-seismic coupling mechanisms, and measuring the acoustic impedance of porous materials.
The group also carries out work on developing and improving non-invasive techniques for measuring the acoustic impedance, impulse response and internal geometry of ducts such as musical wind instruments, airways and pipeline sections. Such techniques include acoustic pulse reflectometry, a Two-Microphone-Four-Calibration impedance measurement procedure, and capillary-based impedance measurement methods.
The Acoustics Research Group has a range of equipment including one fully anechoic chamber and one semi-anechoic chamber. These can be used for testing the level and directionality of noise emitted by sources such as loudspeakers, electrical goods etc.
