Abstract
The embodiments herein provide an apparatus and method for cancelling signal noise. According to one embodiment, an apparatus for cancelling signal noise has a sensor or receiver to capture the undesirable signals. A transducer converts the energy of the captured signals and modulates the captured undesirable signals. A signal inverting circuit is connected to the transducer to generate the inverse of the captured undesirable signals by inverting the amplitude of the undesirable signal while maintain the frequency at the same level. The generated inverse of the undesirable signal transmitted by a transmitter is received by a receiver and output through a speaker so that the output inverse of the undesirable signal is combined with the undesirable signal to produce a desired signal environment.
