Abstract

Triple panel walls are used in many situations but there are few readily available methods for predicting their performance. A common example of a triple panel wall is a masonry wall with light weight plasterboard linings on each side. Such walls can have significant transmission at low frequencies. This paper will describe a lumped parameter model for predicting the low frequency performance of such walls.
