The sound reducing foam in these panels has a polyurethane base, with a chemical makeup that enhances air resistance preventing the sound from traveling quickly. There are some other soundproofing materials in the market but acoustic materials reign supreme.
Some panels are made of fiberglass, a material that performs well in creating air particles to induce the disappearance of sound wave energy. You may also come across acoustic panels made from intertwining carbon weave and polymer resin. It is important to understand what sound reducing foam is to better understand which you will need to install.

Where to install acoustic foam panels?
Understanding where sounds gets trapped in a room will help you in knowing where to start in the process of installing acoustic foam. Selecting where you want to install your acoustic foam will depend on the reflection point of your sound source, which in most cases are speakers. So the first task will automatically be to find the reflection points, which you will measure from your tweeters, small speakers embedded in your column, or box speakers.
Sound reflection happens on all four walls or six depending on the shape of your room. If you have four walls, you will have to install the panel on the front wall where your TV or sound system is and the back wall. It would be best to use smaller panels to fit together with the TV set.
Corners also enhance sound bounces, so you should also put some panels in each corner (Base traps). You can also decide to place them on the back walls near the corners and side walls near the corners of the front walls. That way, you will have stopped side-to-side sound wave reflection and any wave that could bounce from front to back.
You don't need to cover the entire room with sound attenuating foam panels to get that sound quality, But if need be, you can cover as much space as you want.
We recommend covering all four walls in commercial boardrooms, home-offices, and other places where it is difficult to determine the reflection. It is important to note that the number of acoustic foam panels you need will depend on the shape and size of the room.
While most people only cover walls and corners, the ceiling is also a serious consideration when you want the best sound acoustics. You can always utilize this crucial area to improve functions with various acoustic designs for the ceiling.
When installing acoustic foam panels, it would be best to apply your panel to cardboard or wood and then anchor them to the wall.
You could also nail or staple the panels but remember those items go straight into your wall and ceiling and could damage your finishing.
Sprays adhesive is better than nails or staples, but it provides a more permanent solution and rips the paint off your walls; suppose you decide to remove the panels later.
