徴とする消音装置。The aircraft includes an enclosure provided with an air silencing mechanism for primary air and/or secondary air, and exhaust gas from the aircraft is mixed with secondary air gas from the secondary air silencing mechanism of the enclosure. An air-cooled silencer for aircraft having a configuration in which the noise is muffled by an exhaust silencing mechanism through an augmentor and then exhausted, and the augmentor has a configuration in which a constant volume or a different volume is formed on the circumferential surface of the inner wall of the main body of the augmentor. A sound muffling device characterized in that, in addition to arranging a cylindrical sound absorbing material in which a plurality of defined air spaces are provided, each of the chambers forms a branch passage communicating with a gas flow path of the sound absorbing material.
