Problems solved by technology

[0005] However, when a sound output device such as a speaker is used to reduce noise inside a car, the resulting sound may feel artificial or unnatural to the user.
In addition, active noise control techniques using opposite-phase signals output from audio speakers have issues including ineffective removal of low-frequency noise, such as the roar of an engine

Abstract

A noise control system and a method are provided. The method includes receiving, by a controller, a reference signal in response to a noise and an error signal that corresponds to residual noise. A control signal is generated for cancelling the noise based on the reference signal. In addition, the controller outputs a vibration according to the control signal to generate a cancellation signal for cancelling the noise. A phase delay of the reference signal is compensated for by the controller and updates a filter value of the adaptive filter based on the reference signal passing through the path compensation filter and the error signal.

Description

[0001] Cross References to Related Applications [0002] Pursuant to 35 U.S.C. §119(a), this application claims the benefit of Korean Patent Application No. 10-2014-0103941 filed on Aug. 11, 2014, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to systems and methods for controlling noise, and more particularly, to systems and methods for actively controlling noise that reduce vehicle interior noise. Background technique [0004] Generally, a passive method using a sound absorbing material, a sound insulating material, or the like is used as a method of reducing noise inside a vehicle. However, this passive noise reduction method is limited. Recently, an active noise control technique has been developed that reduces noise by using a sound output device such as an audio speaker to generate a signal having an opposite phase to the noise. Various noises may be generated during driving, including noise ...
