    • 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.
    • 提供了一种通过阵列扬声器来控制声场的方法和装置。 该方法包括基于抑制从阵列扬声器发出的声音的抑制区域的声压比和强调声音的强调区域来计算控制输入信号的声压的滤波器的系数,以及声压效率 强调区域,通过基于计算出的滤波器系数,对输入信号进行滤波,生成多个输出信号,将声音聚焦到加重区域,并根据生成的多个输出信号输出声场受控声音。 因此,与阵列扬声器相距一定方向和距离的收听者可以清晰地听到声音,而不戴耳机或耳机,以将声音聚焦到听众。
