Funded Activity Summary

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.
