Summary:A sound sensor assembly may comprise: an omni-directional sound sensor having a first direction pattern; a plurality of directional sound sensors disposed to surround the omni-directional sound sensor, comprising a plurality of resonators each having a different resonant frequency, and each having a second directional pattern; and a processor that obtains output signals from a non-directional sound sensor and a plurality of directional sound sensors, calculates a sound signal having directional by selecting or selectively combining at least one among the output signals, and obtains the sound around the sound sensor assembly using the sound signal. 음향 센서 어셈블리는 제1 지향 패턴을 갖는 무지향성(omni-directional) 음향 센서, 무지향성 음향 센서를 포위하도록 배치되고, 각각 서로 다른 공진 주파수를 가지는 복수의 공진기들을 포함하고, 각각 제2 지향 패턴을 갖는 복수의 지향성(directional) 음향 센서들 및 무지향성 음향 센서 및 복수의 지향성 음향 센서들로부터 출력신호들을 획득하고, 상기 출력신호들 중 적어도 하나를 선택하거나 선택적으로 조합함으로써 지향성을 갖는 음향 신호를 산출하고, 음향 신호를 이용하여 음향 센서 어셈블리 주변의 음향을 획득하는 프로세서를 포함할 수 있다.
