Abstract

For noise intrusion problems, such as road traffic noise into apartment buildings, the ability to quantify the insertion loss of balconies and building facades is an important consideration. This thesis develops analytical models to calculate the insertion loss, which are compared to the direct solution of the wave equation using the boundary element method. In this manner, it is possible to mathematically explain phenomena such as negative insertion loss in the context of the trapped modes of the open cavity system, and frequency dependent values can be efficiently calculated for various geometric configurations and soffit treatments.
