dyna mat is an excellent media for sound damping. but expensive. using a layer or two of outdoor carpeting is effective too. placing your sump on rubber legs will reduce vibration transmission from the sump to the stand or simply placing it on a couple layers of outdoor carpeting will work too. the problem with carpeting is if it gets wet in multiple layers its a pain to get dry and can cause mold/mildew problems.

There are vendors that sell "house brands" of Dynamat. Dynamat is the original stuff and it's crazy expensive, but I think the house brands are a good bit cheaper.
Try googling Parts Express till you find their site, and search for Dynamat. They've got many versions of dampening material to look at.
IME the biggest thing you can do is to isolate vibration. Once a plywood stand starts vibrating, it becomes one huge speaker. Putting your sump on rubber feed as was suggested, putting a pad of filter media between your pump and the sump bottom if you use submersible pumps, they all help.
I've also created flexible junctions between the pumps and my hard plumbing using spa-flex, that works fairly well.
The biggest thing you can do if you are a stand builder is to close the gap between the stand and the wall. Most people build stands as a load bearing frame surrounded by a decorative "skin." By building it so the skin extends back past the frame, you can push the stand hard against the wall (even using weather strip to seal it against the wall) and still have room in the back for your hoses, wires, etc to pass from the back of the tank down below.

Just make sure your sump is supported evenly. I wouldn't think in most cases that 4 feet in the corners is enough. I would suggest going to the Depot and buying a package of those rubber pads that you put on cabinet doors to keep them from banging shut. Spread 10 or more around the perimeter, and some in the center if it's an acrylic sump.

What a cool idea! Never thought of that.
You're talking about that stuff that they put on gym floors and in production lines as anti-fatigue matting, right?

Well I used some styrofoam I got from my job for undereath my sump. It reduce the vibration a lot. Next im going to insulated the stand walls with some of that Dynamat.
One more question how do you quiet a overflow? Instead of having that "waterfall sound" I want it to be quiet. Any Ideas?? Thanks
