New Millennium Products Acoustical Panels Studio Sound Foam Wedges MADE IN THE USA with Fire Retardant!

Although I have read the reviews about being too thin, I noticed no one really said how well they worked. I glued these panels to the roof of a metal building, and they do an amazing job of cutting the noise. I have 2 buildings so I could do a comparison, prior to installing in the second building. I highly recommend to anyone wanting to dampen noise.

A lot thinner than what I expectedBelow the cone there isn’t much padding

They are a little thin, but work well. Cant beat the price

Came fast, looks good. Just doesn't come with anything to mount it with.EDIT: This is so thin it does nothing. You're essentially paying $20 for foam that costs less than 2. I really regret buying the wrong thing at this point. I thought it would be ok, but this is awful.
