Abstract The present invention relates to a cabin noise reduction device, which reduces a dominant noise among noises flowing in a cabin, thereby pleasantly maintaining an environment of the cabin. According to the present invention, the cabin noise reduction device includes a reduction device main body in which a through hole is formed at one side and which is attached to a panel forming the cabin so that the through hole faces the cabin, wherein the reduction device main body comprises: a container part having a vacant space therein and provided in the main body; a neck part communicating with the through hole and the container part; and a control part controlling the volume of the container part. 본 발명은 선실에 유입되는 소음 중 지배적인 소음을 저감하여, 선실의 환경을 쾌적하게 유지할 수 있도록 한 선실 소음 저감 장치에 관한 것이다. 본 발명에 따른 선실 소음 저감 장치는 일측에 통공이 형성되며, 상기 통공이 선실을 향하도록 선실을 구성하는 패널에 부착되는 저감 장치 본체;를 포함하여 구성되고, 상기 저감 장치 본체는 내부에 빈공간이 형성되고, 본체 내부에 마련되는 용기부; 상기 통공과 상기 용기부를 연통하는 경부; 및 상기 용기부의 체적을 조절하는 조절부;를 구비하는 것을 특징으로 한다.
