Clamp to suppress floor joist noise transmission?

11 years ago

We are remodeling our 84-year old house. We have a main house unit and an attached in-law unit.

There is significant and annoying foot traffic noise transmission between the units through the floor joists.

Is anyone aware of a "clamp" that could be applied to the floor joists in the crawl space, to stop the sound transmission at a specific location along the joist? I'm imagining something that performs the same function as plucking a guitar string and a finger prevents the vibration from traveling the entire length of the string.

We are also investigating carpeting, and extra soundproofing in one area that has a new floor. We'd like to avoid the expense of removing and replacing pretty and functional high-quality 84-year old wood flooring.
