a sound dampening assembly operably coupled to the tub cover, the sound dampening assembly comprising:

an extension arm that extends from the perimeter of the tub cover, wherein the extension arm extends between a first end and a second end and is attached to the tub cover by passing the first end through the first attachment aperture and the second end through the second attachment aperture; and

a dampening pad positioned on the extension arm to absorb impacts between the tub cover and the cabinet.

2 . The washing machine appliance of claim 1 , wherein the first end defines a hook and the second end defines a resilient clip.

3 . The washing machine appliance of claim 1 , wherein the first attachment aperture is larger than the second attachment aperture, and wherein the first end of the extension arm is sized to pass through the first attachment aperture but not the second attachment aperture.

4 . The washing machine appliance of claim 1 , wherein the extension arm extends between a first end and a second end, the first end and the second end each defining retention features, and wherein the tub cover defines complementary recesses for receiving the retention features to attach the extension arm to the tub cover.

5 . The washing machine appliance of claim 4 , wherein the retention features are configured to slide into the complementary recesses along a vertical direction.

6 . The washing machine appliance of claim 1 , wherein the extension arm is injection molded as an extension of the tub cover.

7 . The washing machine appliance of claim 1 , wherein a gap is defined between the extension arm and the perimeter of the tub cover when the extension arm is in an installed position.

8 . The washing machine appliance of claim 1 , wherein the dampening pad is at least one of a foam, a felt, a rubber, a neoprene, or a resilient polymer material.

9 . The washing machine appliance of claim 1 , wherein the dampening pad is attached using an adhesive.

10 . The washing machine appliance of claim 1 , wherein the dampening pad is attached to both an inner surface and an outer surface of the extension arm.

11 . The washing machine appliance of claim 1 , wherein the dampening pad is a sleeve that slides onto the extension arm and extends around an entirety of the extension arm.

12 . The washing machine appliance of claim 1 , wherein the extension arm is a first extension arm and the dampening pad is a first dampening pad, the sound dampening assembly further comprising:

a second extension arm that extends from the perimeter of the tub cover; and

a second dampening pad positioned on the second extension arm to absorb impacts between the tub cover and the cabinet.

13 . The washing machine appliance of claim 12 , wherein the second extension arm is spaced apart 180 degrees from the first extension arm along the perimeter of the tub cover.

14 . The washing machine appliance of claim 1 , wherein the washing machine appliance is a vertical axis washing machine.

15 . A sound dampening assembly for a tub cover of a washing machine appliance, wherein the tub cover defines a first attachment aperture and a second attachment aperture, the sound dampening assembly comprising:

an extension arm that extends from a perimeter of the tub cover, wherein the extension arm extends between a first end and a second end and is attached to the tub cover by passing the first end through the first attachment aperture and the second end through the second attachment aperture; and

a dampening pad positioned on the extension arm to absorb impacts between the tub cover and a cabinet of the washing machine appliance.

16 . The sound dampening assembly of claim 15 , wherein the first end defines a hook and the second end defines a resilient clip, the first attachment aperture is larger than the second attachment aperture, and wherein the first end of the extension arm is sized to pass through the first attachment aperture but not the second attachment aperture.

17 . The sound dampening assembly of claim 15 , wherein the dampening pad is at least one of a foam, a felt, a rubber, a neoprene, or a resilient polymer material.

18 . The sound dampening assembly of claim 15 , wherein the dampening pad is a sleeve that slides onto the extension arm and extends around an entirety of the extension arm.
