What makes this project interesting in particular is the automatic pan and tilt rotor that is part of the design. This document presents the adaptive noise canceling project that is mandatory for passing the course. and adaptive noise cancelling [7]. The noise signals emitted can be canceled by using a well controlled sound source, this is called active noise control or active noise cancellation (ANC). I don’t know how possible it is for a program to cancel noise, just because it has no input for what noise is going into our ear. White noise is a type of noise that is produced by combining sounds of all different frequencies together.
