After some testing I can confirm that the noise eaters were able to dampen the thump heard downstairs. Roland claims to reduce the noise by 75%, but in my experience it was not this big of a change. I would say it will help reduce the thump up to 50%. The noise eaters do not wobble as much as I imagined.
