Sound attenuation blankets are one big piece that covers the whole area. So sound won’t slip through the cracks and gaps that you’d have with batt insulation. A blanket is usually meant to be exposed while batts are to be covered with a layer of drywall or other material.
What are Sound Attenuation Batts?
Description. Sound Attenuation Batts (SAB's) are unfaced, lightweight, flexible fiberglass insulation batts, designed to deliver noise control in metal stud wall cavities of interior partitions. Manufactured to fit metal framing, they come in 2½", 3½" and 5½" thicknesses, with lengths up to 9'. Click to see full answer.
What is a sound attenuation wall?
Sound attenuation walls are also known as acoustic barriers, noise barriers or noise walls. Sound attenuation walls do not completely block all noise; rather, they reduce the overall noise to acceptable levels. Some walls can reduce construction noise levels by as much as half.

What blown-in insulation is best for soundproofing?
The best blown-in insulation types for soundproofing are loose-fill cellulose and fiberglass insulations. Both of these insulations have a high R-value and high STC value.
Does blown insulation in a ceiling reduce noise?
Batt, blown-in, and spray foam insulation can reduce sound transfer in the walls and ceilings in your home. At the same time, these specialized insulation products help prevent drafts and energy loss. Fiberglass Batts — Besides providing resistance to heat flow, fiberglass absorbs sound vibrations within wall cavities.
What is the STC of fiberglass insulation?
Fiberglass (or traditional) insulation falls in the middle range of options bringing the STC rating to 39. This option provides so a bit more privacy and blockage from sound entry. Open cell spray foam ties with standard fiberglass at an STC rating of 39 as well.
What is the STC rating of Rockwool insulation?
Rockwool Premium Plus™ Insulation has an STC rating of 58* in a brick veneer exterior wall assembly.
Is fiberglass or cellulose better for soundproofing?
One of the biggest benefits of cellulose insulation is its long-term energy savings. In fact, you can save up to 50 percent on your heating and cooling bills! Cellulose is great for re-insulating homes, from attics to walls to crawl spaces and, like fiberglass, offers superior soundproofing abilities.
Is spray foam insulation a good sound barrier?
Based on my research, the easy answer is no. Open cell spray foam performs better than closed cell, but neither is effective at blocking sound transfer. The qualities that make it an excellent thermal barrier also create disruptive resonance and its adhesion couples the wall elements together increasing noise transfer.
What STC rating is considered soundproof?
STC rating goes from 25 – 65. The higher the rating, the less noise penetration. A rating of 25 is no soundproofing, and 65 is complete soundproofing. A standard single-pane window would have an STC rating of 25.
Is rockwool or fiberglass better for soundproofing?
Rockwool is easier to work with than fiberglass and is better for acoustic panels than fiberglass. It is also better at absorbing low-frequency range noise than comparable fiberglass. I recommend using Roxul in acoustic panels and traps, and use the fiberglass in wall and ceiling cavities where it is fully closed in.
How can I get STC 50?
Add Soundproofing Membranes: If you need to achieve an STC of 50 or higher, consider using a soundproofing membrane. These products offer decoupling by separating the drywall from studs, and also significant mass increases.
Does Rockwool deaden sound?
Stone wool provides excellent noise reduction and sound absorption to help you create quieter, more productive environments. Water resistant, stone wool does not rot or promote the growth of mildew, fungi or mold. Non-combustible and fire resistant, stone wool works to contain a fire and prevent its spread.

We suggest acoustic insulation such as ROCKWOOL SAFE'n'SOUND®. Stone wool insulation solutions from ROCKWOOL will help you soundproof and insulate your space with the proven durability to last for the long term without seeing a decrease in performance.
Does Rockwool reduce noise?
ROCKWOOL products are high-density, which makes them extremely resistant to airflow and excellent at noise reduction and sound absorption, meaning that even the nosiest infrastructure sounds quieter.
Can electrical boxes block sound?
It is very unlikely that electrical boxes will block ANY sound when batts are used. This greatly diminishes the sound attenuation qualities of batts. If you are stuck on using sound batts, at least have one side of the wall rocked before batts are installed so there can be a better install.
Do sound batts seal the walls?
The PITFALL of installing sound batts on interior walls. Sound travels through every crack that air travels through. Batts are never decent air sealers. If you have batts installed you will have sound gaps on the edges, around utilities, and around electrical boxes.
Can you use blown in insulation on a sheetrock wall?
How to decide between sound materials. Installing insulation on interior walls has special requirements. If the sheetrock is up, you can only use blown-in insulation. All other options require removal of the sheetrock. Blown-in insulation in this situation is more expensive than simply blowing it into your attic.
Is blow in insulation cheaper than spray foam insulation?
Blown-in insulation in this situation is more expensive than simply blowing it into your attic. If you have one side of your walls rocked, and the other side open, you can have spray foam insulation installed. This will provide you with the best material at a price that can be lower than most other options.
What is sound blanket?
Sound blankets are not all made the same, so before you decide to use them for your project, you should know what type would work best for you. First you should understand the difference between soundproofing and acoustics (sound absorption). Soundproofing materials are used when you need to block sound from entering or exiting a space. The goal here is to create barriers to prevent sound’s travel and reduce the noise level. Acoustics is important when you want to improve the quality of sound inside of a space. Acoustic materials absorbs echoes and reverberations which can build up in large spaces or rooms with lots of reflective surfaces. Acoustics also matters in rooms needing high fidelity audio, like recording studios.
How effective is an acoustic blanket?
Trying to use an acoustic blanket to block sound on its own will be mostly ineffective, but they are VERY effective at two things: (1) reducing echos or reverb inside a space (2) enhancing the performance of an existing barrier. Getting the right coverage is key for acoustic blanket performance.
What is second skin blanket?
Second Skin’s soundproof blankets are used at events like weddings or concerts, anywhere you need to create a temporary sound barrier. They can also be applied as long-term, permanent barriers at your home or business around loud machinery like an HVAC unit or a generator.

Permanent blankets are designed for long-term use in structures like warehouses or shops, or if you’d like to hold on to them for multiple projects.
Why is soundproofing important?
The goal here is to create barriers to prevent sound’s travel and reduce the noise level. Acoustics is important when you want to improve the quality of sound inside of a space.
Do sound blankets look good?
The cheaper sound blankets may not look very good, but they get the job done as long as they have an NRC rating. If aesthetics and the final look matter because you’re a business or care about the design of the room, acoustic panels or other acoustic materials will add absorption with far more design options.
Do moving blankets absorb sound?
Just make sure the blanket you’re getting is actually rated for sound absorption. If you see anyone recommending various moving blankets as a cheap alternative, first look into actual sound absorption blankets that are around the same price and will absorb more sound (better bang for your buck).
