    • A plurality of control points are defined having a known spatial relationship relative to an array of transducers. An amplitude is assigned to each control point. A matrix is produced containing elements which represent, for each of the control points, the effect that producing a modeled acoustic field having the assigned amplitude with a particular phase at the control point has on the consequential amplitude and phase of the modeled acoustic field at the other control points. Eigenvectors of the matrix are determined, each eigenvector representing a set of phases and relative amplitudes of the modeled acoustic field at the control points. One of the sets is selected and the transducer array is operated to cause one or more of the transducers to output an acoustic wave each having an initial amplitude and phase such that the phases and amplitudes of the resultant acoustic field at the control points correspond to the phases and relative amplitudes of the selected set.
    • 多个控制点被定义为具有相对于换能器阵列的已知空间关系。 每个控制点分配一个幅度。 产生包含元素的矩阵,其中对于每个控制点,表示在控制点处产生具有特定相位的具有指定幅度的建模声场的效果在所建立的声场的相应振幅和相位上 其他控制点。 确定矩阵的特征向量,每个特征向量表示控制点处的建模声场的一组相位和相对幅度。 选择组中的一个并且换能器阵列被操作以使一个或多个换能器输出每个具有初始振幅和相位的声波,使得控制点处的合成声场的相位和振幅对应于 所选集合的相位和相对幅度。

    • Disclosed is a security monitoring method determining whether a trespasser is detected and a position of the trespasser in a set security space and monitoring sound generated at the position of the trespasser by using an acoustic image generated from acoustic signals generated by an acoustic generating device and an acoustic measuring device in an array type. An exemplary embodiment of the present disclosure provides a security monitoring system including: an acoustic generating device that generates acoustic signals; a plurality of acoustic measuring devices that receive the acoustic signals; and an acoustic image processing device that generates an acoustic image using a beamforming algorithm from the acoustic signals received in the plurality of acoustic measuring devices and determines a position of a trespasser by comparing the acoustic image after the trespasser is detected with the acoustic image before the trespasser is detected.
