Abstract
It is important to know the sound insulation of partitions in order to be able to compare different constructions, to calculate acoustic privacy between apartments or noise levels from outdoor sources such as road traffic, and to engineer optimum solutions to noise control problems. There are various methods for predicting the sound insulation of partitions that can be used by noise control engineers. This paper presents a comparison of experimental measurements of the sound insulation of lightweight partitions with theoretical models. Single homogeneous panels are examined first, with mass,stiffness, damping and panel size found to be adequate to describe most common building constructions. Double panel walls are then examined, with additional factors of airgap between the panels, connections between the panels and acoustic absorption in the cavity.
