    • A hybrid acoustic sensor can include a first acoustic sensor, a second acoustic sensor, and a mixer. The first acoustic sensor can generate a first signal to represent acoustic data in a first bandwidth around a first center frequency. The second acoustic sensor can be co-located with the first acoustic sensor, and can generate a second signal to represent the acoustic data in a second bandwidth around a second center frequency. A lower bound of the first bandwidth can be at a lower frequency than a lower bound of the second bandwidth, and a higher bound of the second bandwidth can be at a higher frequency than a higher bound of the first bandwidth. The mixer can combine the first signal and the second signal into a third signal to represent the acoustic data in a third bandwidth from the lower frequency to the higher frequency.
    • 混合声学传感器可以包括第一声学传感器,第二声学传感器和混合器。 第一声​​传感器可以产生第一信号以在围绕第一中心频率的第一带宽中表示声学数据。 第二声传感器可以与第一声传感器共定位,并且可以产生第二信号以在围绕第二中心频率的第二带宽中表示声学数据。 第一带宽的下限可以处于比第二带宽的下限更低的频率,并且第二带宽的较高边界可以处于比第一带宽的较高边界更高的频率。 混频器可以将第一信号和第二信号组合成第三信号,以在从较低频率到较高频率的第三带宽中表示声学数据。
