Recently, the market for swimming pool noise and vibration isolation systems in Australia has become more competitive as product suppliers produced new documentation, promoting their preferred systems. Generally, the case is made for stiffer, lower profile elastomer to be used in many situations where high deflection spring isolators would previously have been specified. However, this is without proper consideration of structural dynamics and the vibration source. The purpose of this document is to clarify the technical approach utilised by Embelton in analysing swimming pool isolation applications and, in doing so, share a theoretical basis for system design with respect to both elastomeric and spring bearing systems.
