The invention provides a sound-proof device and a vehicle. The sound-proof device comprises a blocking piece and a protection cover, wherein the blocking piece is connected with a through hole in a metal plate of a vehicle body; the protection cover at least covers the outside of parts of the blocking piece. The protection cover at least covers the outside of parts of the blocking piece, so that the phenomenon that the whole blocking piece is exposed in the air is avoided, the blocking piece is protected by the protection cover to a certain degree, and the service life of the blocking piece is prolonged. In addition, when noise spreads from a noise source to the protection cover, the protection cover can have certain effects of insulating sound and reducing noise, and when the noise spreads to the blocking piece, the blocking piece can have an effect of secondary noise reduction, so that the noise is further reduced, the possibility that the noise interferes with a driver is decreased, and the safe running of the vehicle is guaranteed accordingly.
