The invention discloses a vibration and noise reduction device and an underwater vehicle, and relates to the technical field of underwater vehicles. The vibration and noise reduction device comprises an elastic beam and a mass block, and the mass block is made of a polylactic acid material. The low-density mass block is adopted, the effective vibration and noise reduction effect can be achieved, and the influence of additional mass on the underwater vehicle is greatly reduced.
