There are two approaches for the noise control problem: active noise control and passive noise control. Active noise control is a technique, which aims to cancel unwanted noise by introducing an additional, electronically generated, sound field. It is suitable for low frequency noise problems. An active noise control system consists of one or more control sources used to introduce a secondary disturbance into the structural or acoustic system. This disturbance suppresses the unwanted noise produced from one or more primary sources. An important property of this is that they are self tuning so that they adapt to small changes in the system being controlled. Passive noise control aims to attenuate unwanted sound by modifying the characteristics of the environment in which the sound source operates. To control passive noise, a barrier made up of material with high density can be put on the sound source. The aim of building a barrier is to redirect the acoustic power flow away from the source.
