SOUNDPROOFING DEVICE
A soundproofing device according to the present disclosure includes a Helmholtz resonator including: a wall that forms a Helmholtz resonance chamber; and a first opening formed in the wall so as to cause the Helmholtz resonance chamber to communicate with an outside of the Helmholtz resonance chamber. At least a part of the wall is configured by a sound source member that radiates sound. The Helmholtz resonator includes: one or more partition walls formed so as to divide the Helmholtz resonance chamber into a plurality of regions, and a second opening formed in the one or more partition walls so as to cause the plurality of regions to communicate with each other.
