To provide a ventilation system and an acoustic member that improve sound absorbency and sound insulation, and can be configured not to obstruct a flow of air.SOLUTION: A ventilation system according to one embodiment is a ventilation system 1 that is attached to a wall W and comprises an inlet port 2c and an exhaust port E. The ventilation system comprises an acoustic member 10 that absorbs sounds from the exhaust port E. The acoustic member 10 has: a film-like main body part 11 that faces the exhaust port E; and a peripheral part 12 that mutually connects the main body part 11 and the wall W, and is arranged so as to surround the main body part 11. The main body part 11 is configured to partition an internal space into a first chamber S1 communicating with the exhaust port E, and a second chamber S2 to which air K flows from the inlet port 2c. One part 11b of an outer edge of the main body part 11 is fixed to the peripheral part 12, and a remaining part 11c of the outer edge of the main body part 11 is opened, which in turn serves as a communication part 13 making the first chamber S1 and the second chamber S2 communicate with each other.SELECTED DRAWING: Figure 4
