Sound deadening and sound dampening are two different things. Sound transfer vs. sound reflection

To stop transfer, you need mass.

To stop reflection, you need something to absorb the reflections.

To absorb reflections, your talking about panels placed at the right locations that absorb the initial and subsequent reflections.

There are off the shelf options, or you can make them out of a frame with insulation infill - preferably mineral wool. Cover this with a acoustically transparent fabric - I usually spec GOM fabrics, but there are others. Placement can either be trial and error or you can figure out the math based on the source.

Post links. But yes, what you want to do should help. Space them off the wall if you can. The other option, is to drape some from the ceiling. (if you can add some absoprtion behind them even better)

Reach high, think big, work hard, have fun.

the Acoustimac have their test results which look good, I am sure the HD ones would also work. Advantage there you can buy them try them, and return them if your not happy.

It doesn't really matter what Phil is saying, the music of his voice is the appropriate soundtrack for a bicycle race. HTupolev

Was at a restaurant Friday night. They had an eggcrate type material stapled or glued to the underside of all the tables. I'm assuming it was for dampening. Wonder if that would work under our dining room table to deaden some noise. Have the same problem in our 1st floor. Open floor plan, hard wood floors. Don't think the wife would go for the sound dampening panels on the wall

She may go for something like this.
