The price of soundproof drywall varies by type and by size. The average price for acoustic sheetrock is around per panel. This is around double the price for a regular sheetrock panel which ranges from -.
Soundproof drywall, also known as pre-damped drywall or acoustic drywall, is constructed in a unique way from standard drywall. Manufacturers create standard drywall with a combination of gypsum, clay, and mica between two thin layers of paper.
Some people choose to double the layers of sheetrock to increase the STC amount and put a sound barrier like Green Glue between the layers.
What is Soundproof Drywall?
*STC: Based on the type of frame (wood or steel) and on the type of drywall and insulation of the facing wall.
Sound Transmission Class (STC)
| STC | What can be heard at this level |
|---|---|
| 25 | Soft speech can be heard and understood |
| 30 | Normal speech can be heard and understood |
| 35 | Loud speech can be heard and understood |
| 40 | Loud speech can be heard, but not understood |
| 45 | The threshold at which privacy begins |
| 50 | Loud sounds can be heard, but are very faint |
| 60+ | At this level, good soundproofing begins. Neighbors generally are not disturbed by very loud speech from inside. |
*STC: Dependent on the type of frame (wood or steel). Wood frames produce a higher STC score.
Soundproofing your room is also good for your overall well-being. Controlling noise in your home will make your home a more peaceful place. It will also allow early birds and night owls to function well in the same house. According to a study by the National Institute of Health, limiting the noise while people sleep will lead to better quality of sleep.
Standard Drywall vs Soundproof Drywall
Pabco Gypsum owns Quietrock sheetrock which was first developed in 2003. Quietrock uses “thin wall technology” so that you don’t have to sacrifice floor space to have better sound damping. They have acoustic sheetrock that measures from ½”, ⅝”, and 1 ⅜” thicknesses.
Cost of Soundproof Drywall
National Gypsum features Gold Bond building products including Gold Bond Soundbreak acoustical panels. These feature a viscoelastic damping polymer between two layers of mold-resistant gypsum board. These boards have a high-density gypsum core that is held between layers of their trademark PURPLE paper. This paper is 100% recycled and is mold, mildew, and moisture resistant.
Deciding Which Kind of Drywall to Use
The most important question people ask when determining if they should use soundproofing drywall is, does it work? The short answer is yes. Piece for piece, soundproofing drywall is more effective at dampening sound than standard drywall.
- Cost – The price tag of soundproof sheetrock is much higher than for standard sheetrock. Depending on the size of your room, the cost of this specialized acoustic drywall may be more than you want to spend.
- Frequency of Use – The number of times that the room will be used can help you determine if the extra cost is worth it. Rooms that are used every day compared to just once a week will have different considerations.
- Level of Noise – The level of noise that will exist in the room is an important component of your decision. The higher the level of noise, the more important it is to employ measures to limit the sound.
- Location – The location of the room in the house will help determine the type of sheetrock to use. If your new home theater is located in the basement, the floor will also help provide a barrier to the sound. But if you put it in a room that is on the same level as your other rooms, you may need an extra sound barrier to allow others in the adjoining rooms to live without the constant noise.
- Comfort Level – Every person has a different level of discomfort with noise. A person with deep sensitivities to noise will be more willing to spend the extra money to be more comfortable.
- Noise Restrictions and Neighbors – Be aware of the noise ordinances in your area. Also, even if the noise of your daughter’s beginning violin practice does not violate a city noise ordinance, be sensitive to the peace of your neighbors.

CertainTeed Acoustic Drywall
If you are creating a home theater or a room for your son’s band to practice in every day, this level may not be acceptable. Many soundproof drywall sheets alone have STC scores of 50-80 alone. The higher the STC score, the higher the price tag for the soundproofing drywall.
When deciding which is the best soundproofing drywall to use, it is important to understand the Standard Transmission Class (STC) score of a particular drywall. The STC score was developed in 1961. This number score measures how much sound is blocked by going through a particular material. Therefore, the higher the score, the more sound is blocked. A soundproofing score of 20 would mean that you could hear almost everything in the next room, but a score of 60 would be an excellent rating.

|---|---|---|---|---|---|
| SilentFX Quickcut | ½” | 48” | 8’,9’,10’12’ | 2.1 lbs/ft2 | 41-54 |

Which is the best soundproof drywall available?

Because sound travels along hard surfaces, the internal layer absorbs sound. This makes soundproofing drywall better than multiple layers of drywall for soundproofing.
Are there any other soundproofing alternatives to acoustic sheetrock?
+You place retrofit boards over existing sheetrock, so the STC depends on the sheetrock and insulation under the retrofit board.
