Soundproof A RoomIf you have been meaning to look for effective ways to minimize the amount of sound coming out or into the room but are clueless on how to start, read on to find out several important things you need to know on how to soundproof a room or by simply using sound absorbing foam into your room.

Before everything else, you have to know that there are actually various methods on how to soundproof a room. The right method is the one that is most suitable for the type of room you have. Since you also need to spend money, it’s advisable for you to set aside a budget.

To effectively block the flow of sound that flows in and out of the room, you have to know where the noise or sound comes from. Noise comes as a result of sound vibrations. A vibration results from the back and forth movement of a sound wave. The best way to prevent sound waves from bouncing back and forth in the walls of a room is to install any material that can absorb sound waves to get rid of the noise it produces.

However, if you are renting a room, having your walls built this way may not be the best option for you. Instead of annoying your landlord, you can just create a buffer that prevents sound waves from escaping the room while simultaneously preventing external noise from coming in.

If you find that you may be a little bit low on the budget or you don’t have enough time to undertake this type of project, you can employ less expensive and less drastic methods. There are simple ways to dampen noise inside the room. For instance, you can easily lay down a carpet or hang drapes over your walls and windows to minimize noise. Although these may not prove to be the best solution to dampen unwanted noise in your room, you can save a lot of time and money from this simple technique. Besides, you don’t really need to go all out on soundproofing a room unless you are planning to turn the room into a recording studio or something like that.

Another effective way on how to soundproof a room is to place rough-surface furnishings in your room. As compared to plain smooth surfaces, having rough surface furnishings installed in your wall can effectively absorb sound waves. This can be achieved by simply spraying a type of acoustic spray texture to your room’s ceiling or walls.

These are just some of the ways to dampen the noise in your room. Given that you have ample budget for this project, you can explore other, more effective ways to soundproof any room you want.


There is no avoiding sound wherever you may go, except perhaps if you are in a vacuum or in outer space. No matter how hard you try not to create any form of noise, you are still bound to create vibrations that are audible to keen-eared people and animals. However, there are times when you have to block out unwanted sound for the sake of peace and quiet. Examples of these situations are when you are meditating, doing an audio recording, sleeping, or in a place of worship.

If you have the means and authority to tinker with the venues where these activities are held, you will benefit greatly if you install sound absorbing foam spray on these rooms. This will help keep unwanted sound like echoes and external noise from penetrating through the walls.

That’s not all. Sound absorbing foam spray also has another important purpose other than sound absorption: providing insulation.


Foam Spray as Insulation

Sound Absorbing Foam Spray

Sound absorbing foam spray can be used as insulation for a house. They have excellent R-value rates (measure of resistance to heat) ranging from 3.5 to 6.0, which make them effective insulators for houses situated in cold locations. There are two kinds of spray foam used for this purpose: closed-cell polyurethane spray foam and open-cell polyurethane spray foam. Both are very durable and hard-wearing. Closed-cell polyurethane is excellent at retaining gas, which further strengthens its capacity as an insulating material. It is also highly resistant to water. Open-cell polyurethane may not be as good as the former when it comes to insulation capacity and water-resistance, but it is still a very good material for home use.


Foam Spray for Sound Absorption


Using foam spray in addition to sound absorbing foam panels will help to completely block external sound from penetrating an audio recording room. The foam spray is usually stuffed right on the corners and crevices of the walls and roof before the foam panels are installed.

There are also other places where you can install sound absorbing foam spray besides audio recording studios. They are also used in machinery rooms where large and extremely noisy machineries are humming and rattling 24/7; in nightclubs where there are soundproof walls; surrounding generators or chambers containing energy-generating machines; inside cooling systems and computer CPUs; and beneath skateboarding ramps.


Advantages of Using Spray Foam


Even though sound absorbing spray foam is more expensive than your average polyurethane foam and fiberglass material, it is easier to install because of its “spray” orientation. You can easily get the foam to stick into the crevices and small corners of a room or in any other location. When properly and sufficiently applied, customers can be assured that their homes will be free from cold drafts and unwanted noise.


There are many venues where sound absorbing foam sheets are needed, mostly for rooms where it is imperative to have clear and crisp audio reception. Examples of these rooms are audio recording booths, cinemas, theaters, meditation rooms, and places of worship.

In these places, it is important that the sound created within the room will not refract on the walls. The walls need to be reinforced with special materials that will prevent echoes from forming audibly and disturbing the much-required quiet or penetrating through the music and sound that are being captured on tape. The integrity of sound in these places is very important.

This is why sound absorbing foam sheets come are very important. Sound is very difficult to stifle, all the more if they are echoes created from refracted vibrations within the room itself.

The privilege of soundproofing or even sound absorbing foam computer and echo-proofing a room is not only limited to malls, churches, big-time recording studios and the like. You can also create a room suitable for audio recording, quiet meditation, and prayer if you learn how to install these foam sheets properly.


Sound Absorbing Foam Sheets

The following are simple steps in installing sound absorbing foam sheets:


1. Select the right kind of foam for the room. There are many kinds of foam and other materials used for sound absorption. Polyurethane foam, melamine foam, spray foam, fiberglass–even egg trays are used as alternative soundproofing material. For convenience’s sake, choose foam sheets that fit your budget and suit your needs.

2. Measure and cut the sheets accordingly, preferably in half-wall lengths so that they’ll be easier to install. You can easily cut them using a sharp knife. If you have to use scissors, use the large, wide-blade ones. Tiny scissors have a tendency to compress the foam and reduce its integrity as a sound absorbing material.

3. Use sturdy Velcro fasteners to attach the foam on the walls. Place them on strategic locations on the walls first: near the top, the bottom, and along the middle. You may need to put up more Velcro fasteners at close intervals to secure the foam’s position on the walls.

This will allow you to install the foam sheets with minimal damage on the walls. Normally, foam sheets are attached using liquid adhesives that could permanently damage wall surfaces once the sheets are removed.

4. Attach the other halves of the Velcro fasteners at the back of the foam sheets.

5. Carefully align the Velcro on the foam sheets to those on the walls. Press the meeting points for good measure.

For people who have their own bands and are often recording songs in a makeshift recording room, knowing how to install sound absorbing foam sheets will be a definite advantage. The same goes for those who have a private multimedia room and mini-cinema in their own homes.

Sound Absorbing Foam Panels For Audio Recording Rooms

In audio recording studios, it is important for the sound being recorded to be crisp, clear, and sharp. All external sounds coming from outside the room have to be completely eliminated so that they won’t be audible in the final recording. This is crucial if you are recording a song or dubbing the audio support for an animated movie clip. If external sounds make it to the final cut, it would be a big turnoff to the executives and producers.

Other than avoiding the hubbub of slamming doors, passing cars, and yelling people by means of sound proofing material, you also want to avoid echoes and shrill, ear-piercing sounds produced by fluctuating frequencies in the recording room. These create a fluttering and slapping echo which is just as bad as external noises.

If you normally do recordings in a room at home, you can install sound absorbing foam panels on the walls, floors, and ceiling. This will help you create a flawless recording without the echoing that is likely to occur in amateur recording studios.


Components of Sound Absorbing Panels


These panels are commonly made from polyurethane or melamine foam, batting made from cotton fiber and fiberglass. The panels are narrow and usually measures 300-500 millimeters across and nine to 38 millimeters thick. Of course, customers and builders can adjust the dimensions of these panels according to the needs of the recording room. They also come in different colors and styles to fit various interior decorating themes.

For the foam panels, they are usually attached on the panels in its originally smooth and flat form. Some manufacturers create them with a serrated, wave-like surface though, to better prevent the occurrence of sound echoing. These sound absorbing panels look pretty much like egg trays (which, incidentally, are actually another option for sound absorbing foam panels.


Other Alternatives

Besides foam, the most typical and easiest means of absorbing sound is to install drapes on the walls of the recording room. On the downside, they do not completely eliminate echoes; they also fail dismally at preventing outside noise from penetrating the room. If you want to have a very effective recording room with excellent sound absorption, go for the foam panels or use sound absorbing foam spray.




A word of caution though for people who plan to install sound absorbing foam panels in their rooms: these are commonly permanent fixtures that will cause damage on a room’s walls once you attempt to remove them. They are attached with permanent adhesives that are very durable.

Sound absorbing foam panels—along with sound proofing panels—are the best choice if you want to create the most perfect audio recordings.

As computers age they lose that soft, smooth hum that—for some—is very comforting to the ears. What replaces that sound is usually a loud, rattling noise that seems to come from the rear of the computer. It sounds remarkably like loose screws and fans rattling around on a hard metal-and-plastic case. Instead of opening your PC tower or getting a technician to tinker with its innards, you can instead install sound absorbing foam in your computer.


Sound Absorbing Foam for Computers


Muffling Computer Noise

There are people who don’t like the idea of using sound absorbing foam. Computer fans will naturally wear out and produce noise in the process; however, using noise mufflers might just disguise the true condition of the machine and make you unaware that it actually needs repair already. This is indeed sound reasoning, but there are people who can’t afford to consult professional technicians each time their computer rattles. That doesn’t mean though they have to endure the distracting noise for as long as it lasts. They can instead use specially designed sound absorbing foam for computers. They are usually made from melamine foam, a material that effectively deadens sound waves.

Cause of Computer Noise

The noise produced by a computer usually comes from its cooling fans. As the machine gets older the fan accumulates dust and other bigger particles that lodge on the bearings. Dust bunnies that form on the blades will be flapping around as they spin; and if it catches some bug or large bits of dust it will create that rattling sound. Another reason may be that the cooling fans have started to rust. This will roughen the surfaces of its joints and create a buzzing sound. In this case, it would be a better idea to get your technician to replace your cooling fan.

Except for the last situation, regular cleaning and some sound absorbing foam Panels for computers will be enough to quiet down your machine.

Why Use Noise Mufflers?

A logical question that will come to mind is, why don’t you just send your PC off for repairs? There’s bound to be something loose that’s causing that noise.

The thing is, damaged or loose screws and bearings isn’t always the cause for this. If this is indeed the reason, your PC might as well not turn on at all; but if your PC works just fine and is in perfect condition except for this deplorable flaw, it is likely that there is no actual damage that needs to be fixed. If you insist on overhauling your PC to get rid of the noise, you could just be wasting money on repairs and parts replacements that are not absolutely necessary.
