Goodhoily Anti-Vibration Pad 24 x 24,3/5 Thick- Rubber Vibration Pad -Sound Absorbing Mat- for Dryers, Fitness Equipmen,Audio Equipment(Square) Black

I put this under a washing machine that is in a closet and generated a lot of noise. It was a significant improvement. I would guesstimate at least a 10db reduction in noise. Highly recommend this mat!

I have a river stone bathroom floor with a portable washer so I needed something to be a stable and noise cancelling barrier between the two. The size was perfect. It works great! The washer doesn’t move and the vibration is gone!!
