This paper presents the results of some experiments on the use of structures of aerodynamically-shaped elements as narrow-band sound reflectors in a duct. The structures are tuned to give maximum attenuation for frequencies determined by the Bragg reflection condition, and are thought to be of speci

An approximate method for calculating the noise generated by a turbulent #ow within a semi-in"nite duct of arbitrary cross-section is developed. It is based on a previously derived high-frequency solution to Lilley's equation, which describes the sound propagation in a transversely sheared mean #ow.
There is increasing evidence that moments are signi®cant contributors in machine induced structure-borne sound. Omission of these components in prediction can therefore lead to an underestimate of total power in some cases, although it is recognised that considering all transmission paths in predict
The analysis of structure-borne sound transmission is obscured by the complicated nature of the dynamic interaction between source and receiver at each contact point. There is little measured data because of the practical dif®culties in directly measuring forces and moments at the contacts. This is
