Acoustic Transmission between Coupled Cavities,
Abstract
As part of an investigation of flow induced cavity resonance, experimental studies have been carried out, both in air and water, on systems of coupled cavities (ie cavities connected by a common opening). The work was performed with the aim of examining the effects on sound transmission between cavities, of parameters such as wall flexibility, fluid viscosity and the size of opening connecting the cavities. Theoretical models have been developed to describe the acoustic behaviour of the cavity systems studied, and good agreement is obtained between theory and experiment. It is concluded that, for most practical applications, the effect of viscosity on sound transmission between resonating cavities is negligible. Flexibility of the boundaries is, however, a dominating factor whose effects are particularly noticeable when the fluid medium is water. (Author)
