Abstract
A noise reduction control apparatus and method for detecting a noise signal with a microphone and generating a first control sound for attenuating the noise signal based on control characteristics of a control filter. Further, the first control sound is emitted and measured during a first period. By measuring a sound reflected from an object, a position of the object is estimated. Using the estimated position of the object, the noise is attenuated at the estimated position. Accordingly, it is possible to continuously reduce noise at an estimated position of an object.
