The invention discloses a low-noise damping exhaust silencer. The low-noise damping exhaust silencer comprises a housing, an intake pipe, an expansion chamber and an exhaust pipe, and also a series of damping structures such as a movable separator with penetrating resonance through hole, wherein the front end face of the housing is in smooth transition with the sidewalls of the housing. The low-noise damping exhaust silencer is provided with a damping plate-movable separator combined structure, so that when the engine operates, the size of the intake space can be changed through two-way expansion of the damping plate and the movable separator when the exhaust pipe of the silencer exhausts gas, and simultaneously, the front end face of the housing is in smooth transition with the sidewalls of the housing so that adverse early noise caused by gas shock can be avoided, and moreover, the running noise of the engine can be further reduced and the vibration of the silencer can be reduced, and noise pollution caused by the operation of the engine is greatly reduced. The low-noise damping exhaust silencer is simple and compact without increase in the manufacturing cost.
