Whether you live in a suburban house, apartment, or townhome, you have undoubtedly suffered from noisy neighbors, construction noises, car horns, and other forms of noise pollution. The remedy for this is to either move from your current place of stay (which can get expensive) or soundproof your home. There are many different ways to soundproof your home, but in this article, we will talk about soundproof foam.

Soundproof foam, which is also known as Acoustic foam, is an open-celled foam that absorbs noise and to some extent blocks noise. It is not as effective a noise blocker as it is a noise absorber. You can soundproof certain areas of your home using foam panels and sticking them to the wall inside a room. 

Although the material used in creating a foam is important, the shape of the foam is just as crucial in deciding the effectiveness of the Soundproof. Some of the best soundproof foams are wedge-shaped, egg-crate shaped, and even completely flat-surfaced.

Soundproof foam does not truly block noise from exiting your home or from entering from outside your home. All it does is reduce the noise and echo that you can hear in large rooms or long hallways. In fact, the soundproof foam is only good at absorbing noise and not at Soundproof, despite its name.

There are some soundproof foams that are made with materials, which absorb echoes and ambient noise. These are great to use in creating your own home recording studio. While other foams that are made from composites, can both absorb and block noise.

Using Soundproof Foam

The current levels of sound pollution in our lives are a major drag on our wellbeing and health. The only feasible way to better this situation is to reduce the level of noise pollution we endure in our homes. By utilizing soundproof foams, we can achieve this.

Soundproof foams can be used as panels of foam on walls to block or absorb noise and echoes. In this way, they can help reduce background noise and give us the relief we desperately need.

However, soundproof foams will not completely block all noise. There are two kinds of foams. The kind of soundproof foams, which block some noise, is made using thickly dense materials. Whereas, those soundproof foams, which only absorb the ambient noise, are created using light and spongy material.

As has been mentioned above, the spongy and lightweight foams made with polyurethane melamine material generally are shaped as many little pyramids bunched together. These soundproof foam panels prevent the sound waves from bouncing off the walls and creating noise. 

On the other hand, soundproof foams that are used for blocking noise are flat-surfaced and are made with much denser materials. These noise-blocking soundproof foams are not placed on walls but rather inside the walls to reinforce the sound deadening qualities. 

Tips on how to install soundproof foams on walls

Unless you know what you are doing you will unknowingly do some expensive damage to your walls while going about installing soundproof foams.

Things like using glue or adhesives to paste the soundproof foam panels onto your walls will damage them and quite possibly require you to repaint your walls when you remove or replace the foam. Similarly, boring holes in your walls using stapler or nail guns is a huge negative!  

Fret not; there is a much safer way to install the soundproof foam on your walls.

1. First you have to make a plan

Diving headfirst into installing the soundproof foam is a bad idea, as you will most definitely end up taking off the foam panels and in the process damage your walls costing you many a pretty penny! You should start by measuring and deciding how much paneling is needed and where on your wall you are going to place the foam. Then, you should mark on the wall using a pencil, or washable-ink marker so you can place the soundproof foams exactly where you want them to.

2. Using cardboard to mount the soundproof foam

This step is crucial for the last and third step. If your plan is to put together several soundproof foam panels into a single large unit then you are better off first. Take a large piece of cardboard and attach the foam panels onto it using adhesive on the backs of the soundproof foam panels. Then after the adhesive has dried off and the soundproof foams are secure, cut away any excess cardboard and mount it on the part of the wall previously marked.

3. Affix the cardboard with the soundproof foam panels on the wall

Affixing the cardboard with the soundproof foam panels on the wall can be made easy by using command strips that are found in every departmental or hardware store. Although panels of soundproof foam are not heavy by themselves, by combining with the cardboard, the weight is a bit too much.

Here is where command strips come in handy. They are made with materials akin to Velcro so if you misplace the cardboard, you can easily take the strips off and move around your soundproof foam panels without damaging the wall. For a good but firm fit on the wall, it is recommended you use at least two strips on each of the four corners in addition to at least one strip on the edge of the centers of each of the cardboard’s four sides.

You can also accomplish this without using any cardboard at all if that is your preference. Just use the command strips on the backs of the soundproof foam panels and attach them to the marked area on the wall. However, this method can be pretty frustrating to make the panels long-lasting since the individual panels might fall off in time due to failures in the adhesive command strips, not to mention you will be using a lot more command strips which will be far more expensive than using a single large piece of cardboard.

Final Thoughts On Soundproofing Foam

Although they are not true sound proofers, using soundproof foam is not without some merits. They are an inexpensive method to temporarily mask unwanted sounds from getting out of your house or from entering your home from outside. 

For example, if you have a newborn in the house you can use the soundproof foam to insulate your baby’s nursery from noisy and unruly neighbors in addition to allowing yourself a good night’s sleep by absorbing your infant’s cries and wails throughout the night! You can also use the dense soundproof foam to turn your garage into a mini recording studio while keeping the peace with your neighbors by not disturbing them with waves of your music.
