APPARATUS AND METHOD OF EQUALIZING A ROOM PARAMETER IN AN AUDIO SYSTEM USING AN ACOUSTIC TRANSDUCER ARRAY

An apparatus and method of enabling equalization of a room parameter with a simple structure and low cost in an audio system using an acoustic transducer array. The apparatus to equalize a room parameter includes an audio signal generation unit to generate two identical audio signals, an audio signal modification unit to modify the audio signals, a sound beam generation unit to transform each of the two modified signals into a sound, to directly transmit one sound to the position of a listener, and to transmit the other sound to the position of the listener such that the other sound is reflected from a reflecting object and transmitted to the position of the listener, a sound magnitude determination unit to collect a sound generated through synthesis of the two sounds at the position of the listener, and a control unit to obtain a delay constant and a filter coefficient.
