Abstract
Active noise control (ANC) creates a set of silent points at the location of error microphones. As a byproduct, a zone of quiet is created surrounding the silent points. Unfortunately, the extension of the created quite zone is small. Moreover, a large part of the quiet zone is occupied by the error microphones. Recently, a number of researchers have independently proposed to displace error microphones and move them outside the desired quiet zones. This idea involves in the modification of ANC adaptive algorithms. This paper looks at available techniques that aims at the displacement of error microphones in ANC systems and conducts a comparison discussion about them.
