A liquid tank assembly for a motor vehicle includes a tank and an absorber assembly. The tank has an inner surface defining a cavity for receiving a liquid substance. The absorber assembly is disposed within the cavity for dampening liquid sloshing noises. The absorber assembly includes a plurality of connected dampener elements. End sections of the absorber assembly are attached to the inner surface of the tank. The absorber assembly is configured to float on a surface of the liquid when a volume of liquid within the tank is between a first critical volume and a second, lower critical volume. The absorber assembly is generally submerged when a volume of liquid within the tank is a generally greater than the first critical volume. The absorber assembly is generally suspended within the cavity when a volume of liquid within the tank is a generally lower than the second critical volume.
