Sound Deadening Foam

Sound Deadening Foam

There are a number of other terms for sound proofing products including  acoustic foam, sound proofing foam and sound dampening foam. For the rest of the article we will mainly use the term sound deadening foam to avoid any confusion. Now let’s start off by talking about the many uses it has.

What is it used for?

This foam 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 tend to use this type of foam 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 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 attach the foam?

You might be asking yourself at this point how you attach the 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 very easily. This spray is specifically designed to create a strong bond that is leak proof, 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 foam. Then again 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.

Auralex FoamTak

Above we mentioned that you need a type of glue to stick your foam onto whatever you are bonding it to. This is one of the good types of adhesive we can recommend. Foamtak is made by Auralax, and is designed for all kinds of foam adhesive applications. Some people have complained that the spray is too runny, but this is only a really an issue if you have the nozzle incorrectly set. You can adjust the degree of how much you are spraying by turning the nozzle. This makes it easy to get just the right amount you need. Overall this is a good , cheap adhesive which will help you get your foam installed in no time. Auralex make their own foam products, so you can be sure they have put that wealth of experience into this product.
