Abstract
This thesis describes by theory and experiment, the effectiveness of an alternate error sensing strategy suitable for the control of general free field sound radiation problems, namely active intensity. In this research, active intensity error sensing has been rigorously analysed: 1. in the near and far field of the disturbance source; 2. to determine its ability to lead to global control via sound power attenuation; 3. in a real control system. The performance of active intensity error sensors were evaluated both analytically and experimentally in progressively more complex environments to identify their capabilities and limitations.
