1. An acoustic sensor assembly comprising:
a non-directional acoustic sensor having a first directional pattern;
a plurality of directional acoustic sensors surrounding the non-directional acoustic sensor and comprising a plurality of resonators having different resonance frequencies from each other, each of the plurality of directional acoustic sensors having a second directional pattern; and
a processor configured to:
obtain output signals from the non-directional acoustic sensor and the plurality of directional acoustic sensors;
calculate an acoustic signal having directivity by combining each of the obtained output signals based on ratios of a signal level output by the non-directional acoustic sensor and signal levels output by each of the plurality of directional acoustic sensors; and
obtain sound surrounding the acoustic sensor assembly in multiple directions, using the calculated acoustic signal.
