Zusammenfassung:	The present invention relates to a sound signal processing method, a sound signal processing device, and a vehicle having the sound signal processing device installed thereon. The sound signal processing device can improve signal separation performance and restore the sound of interest. The sound signal processing device includes: a spacial filtering unit which applies a spacial filter to an input signal to execute a spacial filtering operation in order to obtain a filtered signal including an interest signal; and a mask application unit which uses the interest signal and a space selection rate of the interest signal and noise to apply an obtained mask to the filtered signal in order to obtain an output signal. 사운드 신호 처리 방법, 사운드 신호 처리 장치 및 상기 사운드 신호 처리 장치가 설치된 차량에 관한 것으로, 사운드 신호 처리 장치는 입력 신호에 공간 필터를 적용하여 공간 필터링을 수행하여 관심 신호를 포함하는 필터링된 신호를 획득하는 공간 필터링부 및 상기 관심 신호 및 상기 관심 신호의 잡음 간의 공간 선택율을 이용하여 획득한 마스크를 상기 필터링된 신호에 적용하여 출력 신호를 획득하는 마스크 적용부를 포함할 수 있다.
