WAVE TRAPPING BARRIERS. Traditional noise barriers have poor performance when installed as parallel barriers in front of noise sources with large reflection surfaces. This is because that the reflected noise from the far side barrier or from the source surfaces contributes significantly to the noise level at the receiver location. This project involves the investigation of a novel barrier, the wave trapping barrier (WTB), which is capable of retaining the noise between the source and the barrier ....WAVE TRAPPING BARRIERS. Traditional noise barriers have poor performance when installed as parallel barriers in front of noise sources with large reflection surfaces. This is because that the reflected noise from the far side barrier or from the source surfaces contributes significantly to the noise level at the receiver location. This project involves the investigation of a novel barrier, the wave trapping barrier (WTB), which is capable of retaining the noise between the source and the barrier and to provide maximum sound absorption at the frequencies of concern, and thus to minimize the contribution due to the reflection. The aim is to develop a theoretical and experimental model for the physical understanding and optimal design of the WTB. Outcomes include a new generation of noise barriers that are potentially light-weighted, fiberless and with higher insertion loss.Read moreRead less

Improvement of sporting equipment performance of late has largely ignored the game of cricket. Using the combined disciplines of advanced materials and control technologies, it is anticipated that the traditional cricket bat can be vastly improved while keeping to bat modification guidelines as specified in the rules of the game. This project involves the dynamic study of the bat using established experimental techniques. Once the various regions of high strain rates are determined, smart materials technologies will be used to reduce the transient vibrations transmitted to the batsman. The effect of this monitoring and control is to increase the comfort level and hence, effectiveness of the batsman.Read moreRead less
