Abstract: 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.
