Summary on Grant Application Form |
|
Using numerical and experimental modelling methods the performance of noise barriers under a variety of conditions will be studied. The boundary element numerical modelling method will be developed to overcome problems of non-uniqueness of solution which can occur for some boundary conditions. Developments which allow points sources of sound and surfaces with extended reaction to be accurately modelled will also be made. The effects of ground surfaces of extended reaction, when used in conjunction with noise barriers will be investigated and design guidance developed to optimise their combined use. Examples of such surfaces are porous road surfaces and rail track ballast. The performance of median barriers and low multiple barriers near tracked transport systems will be investigated, as will the degradation in performance of barriers due to the multiple reflections between the barrier and the vehicle side. New forms of barrier of improved efficiency will be proposed and their performance assessed.
