Summary on Grant Application Form |
Sound absorbers are one of the most important means for acoustic control. They are applied to industrial barriers and within factories to provide noise control; this might be done to reduce noise annoyance or to reduce the risk of hearing damage. In many acoustically critical spaces, such as railway stations or recording studios, absorbers are used to reduce reverberance and so improve the intelligibility of speech or the quality of music. This project proposes to exploit a recently discovered absorption mechanism to produce a new type of sound absorber. The mechanism is energy flow across the front face of Schroeder sytle surfaces.The project will begin by investigating the new mechanism within existing surfaces, and then study how novel structures can use energy flow to produce more absorption. The study of new designs will promote a much greater understanding of the absorption mechanisms involved and the production of new prediction methods. It is expected that the potential for surfaces exploiting the absorption mechanism to match or outperform more traditional designs will be proven by the end of the project.
