These are only useful for treating a room, not soundproofing it. Soundproofing requires much, much more, including isolating walls, floors and ceilings from the surrounding building.

Wall treatment panels like these are to help absorb & deflect bouncing waves in a "hard" room so you don't hear the reflections as much bounding off an opposite or perpendicular wall.

These are good if you're making a cheapo vocal isolation booth, to put on a wall behind your listening position to tone down reflections, or behind your nearfield speakers, especially if they're rear ported and too close to the wall.

Nothing will soundproof other than $$$ and a lot of construction.

Realistically, need to double drywall and use Green Glue. Sound panels are for acousticlly treating a room. These foam panels are garbage even for that

These are not to isolate a room. They are to cut down on standing waves from reflections.

Anybody interested in this stuff should know about the big Winer guy:

I didn't try the pyramids, I was trying to get the standard wave ridges. I'm honestly curious if the pyramids do more than the standard ridge pattern, if anyone has any input.

I have two rooms adjoining, one that we rent out and one that we don't. Sound-wise feels the walls are paper thin, can hear chewing through wall. Any suggestions on what I can do?

I thought about trying to fill hollow door with spray foam…is that crazy talk?

Done a bit of residential building -- spray foam doesn't work well for your application. Research Sound Transmission Class (STC) to understand sound transmission and then to help find products that will help mitigate. Previous poster is correct about expense. For residential construction you can find combos for homasote (try HDepot) and QuietRock (a premium product that offers a range of soundproofing solutions for drywall. But isolating studs, top- and bottom-plates in wood framing gives you better results when used with soundproofing products.

Soundproofing (ie preventing outside sound from getting into a room) requires that every connection point between the two spaces be soundproofed. Walls would need sound absorbing insulation (rock wool panels, for example) between the studs. Doors would ideally need to be solid and sealed with a sweep + weatherproofing around the sides and top, like what you'd have for a front door or interior garage door. If there's any open space (as you would have from the gap under a regular interior door), no amount of soundproofing will help because it'll just go straight through the opening. For soundproofing to work, it has to be essentially 100% sealed.

Like the other guy said, these panels are for reducing reflections inside a room. They will have practically no effect on sound isolation, ie preventing outside sound from getting in. Preventing outside sound from getting in is an annoying, expensive process.

We had a similar problem between house floors. We did blow-in insulation between the floor and ceiling. Helped a lot

That is not what the panels are for

Do these help dampen the noise going outside the room for calls?

Not really. They absorb and scatter a little bit of hi frequency waves. They are virtually useless for dampening lower frequency waves like a deep male voice or bass from music.

Could these be mounted on both sides of a wood door to make less sound travel thru it? It's not a traditional door, its made out of shiplap type wood panels about 3/4" thick.... to be clear, I am talking about mostly music from speakers (not bass), and sound from a tv (no soundbar or anything, just regular tv speakers)
