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.
