Sound Deadening Material – Noise Suppression

There are a number of terms for sound deadening materials including acoustic foam, sound proofing foam and sound dampening foam for example. All these terms fall under the umbrella of sound dampening material.

These kinds of products are the best way to create any kind of noise reduction for a chosen area. In this article we are going to look at what it is used for, and take a look at some of the popular products in that range.
First let’s start off by talking about the many uses it has.

Does soundproof foam really work?

The short answer is yes. This sound deadening material is used in a variety of ways, but the first and foremost reason it tends to get used is when it comes to music studios. Music studios use this type of sound deadening panels to soundproof the entire studio which helps them to keep the noise generated to a minimum. This is particular crucial when the studio is operating in a business district where the noise could cause problems for the other businesses. It isn’t only limited to studio use however. Many bands use this type of foam to insulate their practice rooms, which keeps their neighbors from getting too fed up with the noise they make!

Another popular use for this type of soundproof foam is in computer cases. Those of you who have higher end or modded computers know that running powerful graphics cards, or larger 120mm case fans will be all too familiar with how much noise these components generate. Using some sound proofing foam, you can help to tone down the noise a bit, which is especially handy if you sleep in the same room as your computer.

Musical instruments and computers aren’t the only noisy devices however, and there are many other reasons people invest in this type of soundproofing. Are your house walls quite thin? Do you have neighbors or family members who tend to be quite loud or noisy? Or perhaps the tv is close to your room. All you need to do is soundproof the area a bit, then your problem is solved. This can also be used around poorly insulated windows where the sound can come in. Another popular usage is to put it underneath your doors. This is a small area where noise from traffic or passers by can slip in, but using a bit of foam you can get rid of this annoyance quite easily.

How do you install sound deadening material?

At this point you may be wondering how you attach the sound deadening foam to the walls, or wherever you need it to be for maximum sound absorption. The good news is that you can get special foam adhesive spray to attach the foam with ease. This spray is specifically designed to create a strong bond that is leakproof, and is fairly cheap and straightforward to use. If you are only trying to seal off a smaller area such as around a window, then it is recommended that you only use the foam adhesive without any sound absorbing foam. In this instance we are talking about sizes that are 1/2″ or thinner for this particular purpose.

Some folks use a type of caulk to do the job, but it isn’t specifically designed to be used to bond foam to objects. There is no denying it does work, but you should stick to the recommended foam adhesive for the most positive results. The actual adhesive foam spray is only a little more so this is what we recommend you use when you are doing your installation.
We’ve talked about some of the uses for this type of this foam, and how to install it.

Now it is time to take a look at some of the top rated products in this category type. Keep reading to find out more.
