The method of localizing a sound image to a spatial position includes: extracting from a head related impulse response (HRIR) measured with respect to changes in the position of a sound source, first information indicating a reflection sound wave reflected by the body of a listener; extracting from the HRIR second information indicating the difference between sound pressures generated in two ears, respectively, when a direct sound wave generated from the position of the sound source arrives at the two ears, respectively, of the listener; extracting third information indicating the difference between times taken by the direct sound wave to arrive at the two ears, respectively, from the HRIR; and localizing a sound image of an input signal to a spatial position by using the extracted information. According to the method and apparatus of the present invention, by using only important information having influence on sound image localization of a virtual sound source extracted from the HRIR, the sound image of the input signal can be localized to a spatial position with a small number of filter coefficients.

摘要： Provided are a method, medium and apparatus for enhancing an acoustic signal using an auditory property. An acoustic signal is enhanced by generating a plurality of harmonic signals based on a predetermined acoustic signal frequency, selecting harmonic signals, which exist in an area masked by the predetermined harmonic signal, from among the generated plurality of harmonic signals, and outputting harmonic signals remaining after excluding the selected harmonic signals from the generated plurality of harmonic signals. The enhancement results in a bass signal of good sound quality and having a low distortion ratio, without changing the structure of a micro speaker.

摘要： Provided are a method and apparatus for controlling a sound field through an array speaker. The method includes calculating a coefficient of a filter that controls sound pressure of an input signal, based on a sound pressure ratio of a suppression area that suppresses sound emitted from an array speaker and an emphasis area that emphasizes the sound, and sound pressure efficiency in the emphasis area, generating a plurality of output signals that focuses the sound to the emphasis area by filtering the input signal based on the calculated coefficient of the filter, and outputting a sound field controlled sound based on the generated plurality of output signals. Accordingly, a listener in a predetermined direction and distance from the array speaker can clearly hear sound, without wearing an earphone or a headset so as to focus the sound only to the listener.
