Abstract:	Active Noise Control (ANC) is a buzzword in acoustics today. Applied correctly, ANC methods have proved to be better insulators in low frequency noise, than usual absorbers. However, when a broad band noise needs to be controlled, such active methods have di±culties at high frequencies. The main objective of this master thesis is to minimize Acoustic Energy Density (AED) of a broad band signal by means of an active control method. A comparison between such method and an absorption one is done, so as to determine which has better broad band behavior. Furthermore, experimental results are compared with theoretical simulations.
