Welcome to the Acoustics Division?
Welcome to the Acoustics Division. Here you will find the necessary supplies for sound deadening all sorts of rooms, both big and small. (Some examples are studios, rooms that need sound deadening in houses, gyms, and churches.) We have the solutions for light, medium, and heavy sound deadening needs, so browse around to find what you are looking for. All Are Acoustic Foam / Studio Foam is California 117 flame retardant specifications, class A type - Density 2lbs Acoustic Foam Acoustic foam is probably the most important aspect of any studio. It can either make or break a professional or project studio. It doesn't matter how much is spent on recording and monitoring equipment. If the room itself is not treated to its optimum the results will never be as On sells now at an affordable Order Now! good as they could be. Rooms have their own sound already within the room. While the sound is traveling around the room it will come into contact with different surfaces and other sound waves moving around the room. This means that the room can suffer from a lot of acoustic problems. These could include; Reflections, Reverberation, Slap echo, Flutter echo, Poor frequency response, Standing waves, Boom and modal problems..

Colors acoustic foam pricing?
Important: Color Foam goes with color pricing. STANDARD COLOR IS CHARCOAL. When selecting the dimension and quantity, make sure that if you desire colors such as purple, blue, orange, etc., that your order reflects that in the pricing. Your order will start off with the word COLOR-PYRAMID or COLOR-WEDGE, etc. If your order starts off with the word CHARCOAL-WEDGE, etc., then you will be ordering CHARCOAL.

Acoustic FAQ - more Info, mounting/cutting ?
Can the foam be cut down to the size that I need?
Yes, if the standard sizes we carry to not meed your requirements, we can cut the foam down to the size that you need. You can also cut the foam yourself. Using a sharp carving knife or electric knife, the foam may be cut down to size as needed.
How do I apply the acoustic foam to the mounting surface?
We suggest using our spray adhesive, which can be found in the accessories section of our website.
Temporary Hold: For temporary use, apply light amount of spray adhesive to the back of the foam. Then, apply the foam to the mounting surface. Permanent Hold: For maximum hold, wait for the adhesive surface to become tacky before installation. Apply adhesive to both the mounting surface and back of acoustic foam product. How do I apply the acoustic foam to the mounting surface? NOTE: For concrete surfaces, brush off loose particles before installation. How can I mount the foam without using adhesive?
The acoustic foam can be mounted using t-pins, or applying the acoustic foam to a board, then resting or hanging the board on the wall.
Ordering Questions Can I have different colors in the same package? No, when a package can be in a color of your choice, each package can only be ONE solid color. However, when you order more then one pack, each pack can have its own color.
Acoustic Foam Questions What do I need to stop sound from traveling through a wall (or walls)? Acoustic foam can be used to stop sound from traveling through a wall, but it is recommended for improving the clarity of sound in a room. If you were to solely use foam, and cover 100% of the walls with our 4" Wedge foam, you would only block about 20% to 30% of the sound traveling through the wall. If you need to do more, you will need to "build a room inside of a room" to achieve more than 30%. Our Volara and Neoprene foams can be used in this construction.
How much acoustic foam do I need? Typical applications call for 25% to 75% coverage, with the average being 50%. We suggest 50% to 75% for rock, pop, techno, etc.. For jazz, classical, etc. 25% to 50% coverage is suggested.
Where should I place my Wedge & Pyramid foam or Bass Absorbers? For Corner Bass absorbers: >We suggested placing 2 in each corner, starting from the ceiling going down. If you decide to go with 4 bass absorbers in each corner, but the ceiling is higher than 8ft, space the bass absorbers out. Space the bass absorbers evenly, having the top bass absorber touch the ceiling and the bottom bass absorber touching the floor.
>When it is not possible to put the bass absorbers in the corner, you can either put them on the ceiling juncture (proffered), or floor juncture.
For corners that are not 90 degrees, you may want to consider our Male / Female broadband absorbers. (Suggested placement of broadband absorbers are the same as placement of corner bass absorbers) For Wedge and Pyramid Foam: >We suggest starting from the ceiling, and working your way down from there.
For most applications, the foam panels do not need to be lower than 2ft - 3ft from the floor.
Placement should be concentrated more around where the sound originates.
For the wedge foam, they will perform similar if they are horizontal, vertical, or at a 45 degree angle.
If absolute deadness is not required, we suggest placing the foam in a "checkered" board like pattern.
What does NRC mean?
NRC stands for Noise Reduction Coefficient. The NRC of a material can be found by using either the Reverberation Room Method (ASTM C423) or the Impedance Tube Method (ASTM C384). We use the Reverberation Room Method and the general idea of how this method works is:

1) Approximately 72 sq. ft of material is rested on the floor of a Reverberation Chamber. This chamber usually has all hard concrete surfaces. 2) The change in absorption from the empty room to the room with the material is measured. 3) The changes in sound are measured for octave bands ranging from 125 Hz to 4000Hz, recording the differences in Sabine absorption coefficients. The overall NRC rating is the
calculated average of frequencies 250Hz, 500Hz, 1000Hz and 2000Hz.
The higher the NRC rating, the more sound the material can absorb.

What does STC mean?
STC stands fro Sound Transmission Class. This rating is used to compare the acoustic isolation of different materials. The Method used to calculate the STC rating is (ASTM E413) A general idea of how this method works is:
1) Their are 2 rooms, a "source" room which contains a loudspeaker and a "receiver" room which contains a microphone. Between the two rooms is an opening usually sized 8ft by 9ft. 2) In decibels (dB), the sound is recorded from in 1/3-octave bands from 125 Hz to 4000Hz
3) The next step is to record the sound again (same process as above) in decibels (dB) with the material (or materials) completely covering and sealing the opening.
4) Then, the difference between the before and after measurements are calculated and recorded. These measurements are the transmission loss or "TL" of the sound.
5) Lastly, (this may be confusing for some) the transmission is drawn on a graph of 1/3-octave and center frequency versus level in decibels. The STC is the measured curve compared to a reference STC curve. (Exact definition can be found by viewing the ASTM E413 method).

The requirements used to "match" the curves are (1) The reference curve shall not exceed the measured transmission loss by more than 8 decibels in any 1/3 octave band and (2) The sum of all "negative discrepancies" shall not exceed 32. Once these requirements are met, the value of the reference curve at 500Hz is read as the STC of the material (or materials). NOTE: Lab and field measurements may vary 1-5 STC depending on application. This should be taken into consideration when choosing materials for acoustic isolation projects.
Questions about Fire Retardant Foam
Are your acoustical products fire retardant?
Yes, all of our acoustical products are fire retardant. The fire rating can usually be found at the bottom part of the page that shows the acoustic foam. Specific details about the how fire retardant the foam is can be found by clicking the foam next to the "foam types" next to the product picture. All acoustic products have fire retardants chemically added to the foam. They are NOT added to just the surface.
Why go with acoustic foam instead of regular "bedding" or "packaging" foam?
Our acoustic foam products is recommended for acoustic applications because they are much better at absorbing sound, and are fire retarded.
What would happen if fire were exposed to your acoustic foam?
Our acoustic foam will smolder and smoke, but it will not burst into flames. And after the source of fire is removed, the foam will "self-extinguish". (Note: Foam Factory does not encourage exposing our products to extreme heat or fire, and Foam Factory will not be held liable for any injury or loss from the misuse of our products.)
What information is needed to pass my building codes?
Our acoustic foams have been tested in accordance with ASTM E84 for surface burning. (ASTM E84 is the technical equivilant of NFPA 255 and UL 723.) Our acoustic foam meets a "Class A" or "Class 1". This is accepted by most building codes, but please check in your area before installation.
What does "Class A" mean when talking about Fire retardant Specifications?
In regards to the surface burning standard ASTM E84, this test calculates two numbers. One is "Flame Spread Index", and the other is "Smoke Developed Index". These numbers determine whether the material is "Class A", "Class B", or "Class C" (or Class 1, Class 2 or Class 3, respectively). Class A represents that the material will not burn or smoke much, and Class C represents that the material will burn heavily and produce even more smoke. Class B will burn a little more than Class A, and also produce slightly more smoke than in Class A.

Studio Foam Placement?
INFO

Studio Foam : To understand how to soundproof a room, it is first necessary to understand a little about "sound." Sound is composed of waves that travel through a medium. Some mediums, or materials, are more resistant to sound than others. Air, for example, offers little resistance and is therefore a major contributor to unwanted noise in a room. To soundproof a room, however, more is needed than just blocking the flow of sound through air.

Another source of unwanted noise in a room can come from vibrations. A vibration occurs when a sound wave travels back and forth from one object to another. This can happen, for example, when a sound wave strikes one wall in a room, bounces off that wall, and transfers its energy to the opposite wall. That vibration can create an annoying noise problem.

The best way to prevent the noise problem altogether is to construct the room with building materials (studio foam ) that dampen noise.

Step-by-Step to Set Up Studio Foam
A studio must be a soundproof environment for the best possible reproduction of a recording. This can be accomplished in a variety of ways, but the most common method of soundproofing a room is the use of foam products. Studio foam comes in several different thicknesses and styles, and there are overriding aspects that will dictate which type of studio foam to use.

Starting Off

The decision of where the studio foam is needed most can be made using a "hands-on" test. This means to simply clap your hands while moving around the room and listening for long and short echoes. Areas of short echo time will need less foam, so concentrate foam placement in those areas where the hand claps reverberate for longer periods of time. The decision of thicknesses to use is affected by frequency ranges. Lower frequencies will require thicker foam due to the strength and length of the sound wave. Areas where a bass instrument is recorded should have a thicker foam installed on the wall. An alternative to wall-mounted foam is a movable acoustic foam panel that can be placed in different parts of the room.
Advanced Studio Foam Placement
The placement of the sound-dampening material is as important as the type used. There are different requirements for the recording and mixing areas. In the mixing booth, the engineer needs to have as true a reproduction of the sound coming out of the playback monitors as possible. Studio foam should definitely be placed on the walls and ceiling of this area, if not the entire room. A combination of thick foam around the mixing area and a diffusion-type of foam from the mixing desk to the back of the room will sufficiently provide a controlled sonic environment. The foam in the recording area should focus on the walls in general, with an extra effort to address hot spots where frequencies tend to reverberate more. Low-frequency signals will carry farther and collect in corners of square rooms, and there may be other spots that characteristically resonate longer at several frequencies. Installing Studio Foam

Permanent installation of studio foam involves the use of an adhesive to mount the foam to the studio surfaces. There are several studio foam adhesives available that are made specifically for this purpose. Once the adhesive has been obtained, the surfaces where the foam is to be installed should be cleaned and all items should be removed from those surfaces. The adhesive can then be sprayed onto both the back of the foam sections and the surface it is to be mounted on. A minute or two of waiting time will allow the adhesive to become tacky for the best adhesion. The studio foam can then be installed on the surface. A more temporary installation technique may be preferred, and this can be done using pins, brads or other small nails to attach the foam to drywall and paneling. The foam can be removed in the future without damaging the surfaces, other than needing to fill the small nail holes with putty or by painting over them. Home Recording Studio Foam Ideas

With the sophisticated recording equipment available today, even amateur musicians and recording hobbyists can obtain professional results in small home studios. Acoustic foam material is often used, even in home project studios, to create optimum sound recording and listening environments. The Purpose of Acoustic Foam

Unlike soundproofing material, which is used to keep external noise out of the studio, such as road traffic, and to keep sound inside to prevent complaints from neighbors, acoustic foam devices are used to create the proper ambiance in a studio. Sound can bounce off glass windows, walls, ceilings, floors and hard objects. This can cause certain frequencies of sound to be accented and to cause a reverberation or echo. Strategically placed acoustic foam pieces can disperse sound and attenuate desired frequencies. When a song is being recorded or "mixed," and the engineer is listening on speakers placed in the room, the goal is to prevent the room from adding any of its own coloration to the sound. Foam products come in different shapes and sizes to be placed in key locations, such as in the corners of the studio. Bass traps

Bass traps are contoured dense portable flutes of foam that stack up on each other in the corners of a room. They are easily used and are self-standing to combat low bass impact noise. Installing two stacks in each of four corners of your room will assist in trapping bass acoustics and condition the room for balanced sound..

How will i know exactly how much square footage I need for my project....?

NOTE: OK get your tape measure out. Lets talk about one wall only for now, let say the wall is 10'(w) x 10'(h). ok, thats 10 x 10 = 100 or 100sq ft.

(1) Width x Hight = ? sq ft
(2) Now let say you do not wont Acoustic Foam on the hole wall..? (just a small part) maybe 3' x 7' = 27 or 27 sq ft.
(3) Now do this on every wall(s) you need Acoutic Foam on.
(4) thin total all wall(s) up as one grand total. Now that will be your total quare footage.!
(5) sometime its a good idea to add about 10% more just in case you forgot something.
