Foam does not Block Sound Transmission Even covering the wall 100% with 2” thick foam is not going to, to the extent of the person’s expectations, stop that sound from traveling right through the wall. The porous nature of acoustic foam makes it possible for sound to pass through it.
It means that if you want to make a soundproof wall, you need to use a material that blocks sound. If you don’t, then the sound will still travel through your wall and you won’t be able to stop it from doing so. This is because sound travels at the speed of sound, which is the same speed as sound waves.
Sound waves travel in a straight line at a constant speed. So if a wall is made of foam, it will not stop sound at all. It will only slow it down a little bit, but not enough to block it completely.

How do you use acoustic foam in a room?
If possible, mount some of your acoustic foam across corners of your room. The ceiling and side-wall can be used. The large air gap behind the foam will be created by this. This can be the beginning of absorbing the low-frequency resonances mentioned in the previous section.
If you can’t mount your foam on the wall or ceiling, you may be able to mount it on a piece of plywood or other flat surface. If you have a lot of foam, this may not be an option. These are all good places to put your absorbers, as they will absorb the most of the incoming sound.
How can I soundproof my room acoustic?
You need to absorb the sound to soundproof your room. Adding acoustic foam and acoustic panels on walls, hanging blankets over sound entry points, and positioning furniture so that it doesn’t interfere with sound absorption are some of the ways you can accomplish this.
If you want to reduce the amount of sound that enters your home, you can use sound-absorbing materials such as foam, vinyl, or vinyl-coated fiberglass. These materials absorb sound at a lower frequency than other materials, making it easier for you to hear your family and friends.
How thick should my acoustic foam be?
The 2″ thick profile is the most popular and a safe bet for anyone planning a do-it-yourself vocal booth, studio, home theater, rehearsal space, or a broadcasting area. If you want to use it as a stand-alone acoustic booth, 3.5 inch foam is a good choice because it will absorb high, mid, and low frequencies.
Does acoustic foam work both ways?
Soundproofing foam works both ways for the most part, but it’s most effective when the shape of the foam is uniform on both sides. The shape in which it is applied has an effect on the sound absorption of the material. The most important thing to remember is that you want to make sure that the material you are using is not too thin or too thick.
Too thin and it will not be able to absorb sound properly, and if you have a very thin material, it may not work at all. If you don’t know the thickness of your foam, you can measure it with a tape measure or a ruler. You can also use a sound level meter to see how much sound is being absorbed by your material.
Where should I place my acoustic panels?
Place 3′ to 6′ up from the floor in areas with a lot of sound coming from people sitting or standing. Position the speakers at a distance of at least 10′ from each other. Listen to what you are hearing.
How many acoustic foam panels do I need?
While the number of panels you need varies based on the purposes of your space, a typical starting number is 8-10 panels. The number can go up to as many as 25 panels for more flexibility.
For example, if you have a large living room and a small kitchen, you may want to add a few more panels to the kitchen to make it more usable.
If you are using the same space for both living rooms and kitchens, then you can add as many or as few panels as you like, depending on your needs.
Does acoustic foam block outside noise?
The panels absorb sound waves in the room in which they are placed. They can help reduce noise coming from outside, but they won’t block the sound coming in from inside the home.
“It’s not like you’re going to be able to turn on the air conditioner and turn it off and then turn the heat on and off again,” said Dr. Michael J. O’Brien, a professor of acoustic engineering at the University of California, Berkeley.
