    • PURPOSE: A device and a method for detecting sounds in a target space using a microphone array are provided to amplify sounds received from a desired target space and reduce the sounds received from a undesired target space, thereby improving focusing performance. CONSTITUTION: A method for detecting sounds in a target space using a microphone array is as follows. Microphones(512,514,516,518) comprising a microphone array are arranged in a basic form. A focusing with respect to sounds transmitted from a target space is performed based on a preset algorithm while rearranging the microphones. An arrangement of the microphones is determined so that the microphones can maximize the sounds received from the target space. The focusing with respect to the sounds transmitted from the target space is performed according to the arrangement of the microphones determined by the algorithm.

    • PURPOSE: A three-dimensional sound system and a method for generating three-dimensional sound are provided to accurately generate three-dimensional sound effect by compensating time delay of each channel. CONSTITUTION: A speaker array(110) includes a plurality of speakers. A beam calculator(120) provides sound source signals to the speaker array in order to output a plurality of sounds with different directional angles through the speaker array. A sound acquiring part(130) obtains a plurality of sound pressures of the sounds which is reflected by a reflector. A directional angle determining part(140) determines the directional angles of the sounds outputted from the speaker array based on the information related to the sound pressures.

    • A method for generating a virtual sound through a distance measurement and a recording medium thereof are provided to perform a virtual sound having high sense of reality by performing the virtual sound according to motion of user. If a voice or a sound signal is generated, a distance between user and a terminal used by the user is measured(S10). A virtual sound is performed by using the measured distance(S20). The virtual sound is outputted through a speaker(S30). In the step for performing the virtual sound, a head related transfer function corresponding to the distance information measured from a pre-stored head related transfer function data is selected(S21). The virtual sound is performed by convoluting the selected head related transfer function and a sound pressure signal of the voice or the sound(S22).

    • PURPOSE: A method and a device of localizing a multichannel sound signal are provided to enable a listener to feel realistic elevation perception from the sound signal. CONSTITUTION: A multichannel sound signal localizing device (200) includes a multichannel sound signal generation unit (210), a frequency range determination unit (230), and a second filtering unit (250). The multichannel sound signal generation unit generates a multichannel sound signal with applied elevation perception by applying an input sound signal to a first filter corresponding to a predetermined elevation. The frequency range determination unit determines a frequency range of a dynamic cue according to a change in HRTF indicating path information from a spatial position of a real speaker to the ear of a listener. The second filtering unit applies at least one channel sound signal among the multichannel sound signals to a second filter.
