Abstract: There is provided a ventilation-type silencer that uses a porous sound absorbing material and has high sound deadening performance in a low frequency band. A ventilation-type silencer includes an inlet-side vent pipe, an expansion section that communicates with the inlet-side vent pipe and has a cross-sectional area larger than a cross-sectional area of the inlet-side vent pipe, and an outlet-side vent pipe that communicates with the expansion section and has a cross-sectional area smaller than the cross-sectional area of the expansion section. The ventilation-type silencer includes a porous sound absorbing material that is disposed in at least a part of the expansion section, a back space that is a space in the expansion section formed on a side of the porous sound absorbing material opposite to a flow channel connecting the inlet-side vent pipe and the outlet-side vent pipe, and a partition member that partitions the back space. A region partitioned by the partition member forms an acoustic resonator, and the acoustic resonator is acoustically connected to the flow channel.

The ventilation system of the present invention has a silencer disposed at an intermediate position of a ventilation path. In the silencer, a sound absorbing member surrounds a housing in which an in-housing ventilation path extending from an inlet opening to an outlet opening is provided. In addition, an upstream tube body that forms an upstream ventilation path on an upstream side of an inlet opening, a downstream tube body that forms a downstream ventilation path on a downstream side of an outlet opening, a tubular first connecting portion that is connected to the upstream tube body and that links the upstream ventilation path and the inlet opening to each other, and a tubular second connecting portion that is connected to the downstream tube body and that links the downstream ventilation path and the outlet opening to each other are provided. Each of the first connecting portion and the second connecting portion includes an opening portion therein. The closer to the in-housing ventilation path, the smaller a size of a cross section of the opening portion of at least one connecting portion.
