How do I dampen my listening environment?

See if you could find where the sound is reflecting from the floor, to the walls and possibly back to you now.Somebody had an idea on here about using mirrors to visualize where the reflections are coming from.I'm not sure of the method that they described though.It may have been if you could see the reflection of the speaker,the sound would do the same?Possibly walking around and see if you find the reflected sound.Maybe temporarily taping panels in those spots. Hopefully the tape won't remove the new paint.Or have someone hold a sound absorbing panel in the spots you suspect.

They also have foam mattress covers($10 ballpark) you could cut and use to experiment with.♫

Here are a couple other web sites with good products:
ATS Acoustics
Auralex
I am using products from both. The panel I received from ATS seemed well made and arrived very quickly. You could also go the DIY route but I think it's hard to beat the prices of these products even with DIY. Good luck.

Yeah that Auralex is OK,lot cheaper than Sonex.If your handy,get some 704-5 Owens Corning and frame and cover it.......good luck,Bob

Yes, your wood floors may indeed look gorgeous, but what you need now is a gorgeous area rug to accent the room and floor and minimize some of those reflections. Also, lots of oversized Pottery Barn floor-to-ceiling velvet draperies will help immensely.

Then along the floor borders stack a few oversized accent pillows randomly. Finally, add some soft lighting around the perimeter of the room to further highlight the wood flooring still exposed.

This should be a good compromise between aesthetics and room acoustics plus it gives you an opportunity to show off your design talents while still highlighting your cool refinished floor.
