10 Best Sound Deadening Blankets 2025 in the United States

The US Cargo Control Large Sound Blanket is a sizable option designed to reduce noise by absorbing sound rather than fully blocking it. Made from a woven cotton and polyester blend with a recycled cotton filler, it offers durability and environmental friendliness. Its large size (96 by 80 inches) and weight (12 pounds per blanket) make it substantial enough to effectively dampen noises in spaces like recording studios or to help reduce sound from neighbors.

The blanket includes nine grommets along one side, facilitating easy hanging where needed. It is machine washable, although due to its recycled material, it may not be ideal for protecting light-colored items from staining. This blanket does not claim to be fire resistant, so it may not be suitable for all environments.

This product is well suited for those who need a reliable sound absorption solution and want a heavy-duty, washable blanket that’s easy to install, but it is not intended to completely soundproof a room or block noise entirely.

The Suvony 2 PCS Large Sound Dampening Blanket is a versatile solution for anyone looking to reduce noise. Each blanket measures a generous 96 x 80 inches, making it capable of covering large areas such as windows or doors. The material is a blend of dense non-woven fabric and synthetic cotton, which is effective at absorbing sound waves and reducing vibrations. Weighing in at 12.13 pounds per blanket, it's clear that these are sturdy and built to last, with double lock 'Z' stitching and reinforced edges enhancing durability.

Installation is a breeze thanks to the 9 metal grommets and included straps, allowing you to hang the blankets effortlessly. The blankets can be used in a variety of settings including recording studios, home offices, and even outdoors for camping or as a pet barrier. They also double as blackout curtains, furniture protectors, and more. One caveat is the initial odor due to packaging, but this can be resolved by airing the blankets out after unboxing.

The blankets are quite heavy, so handling and installation might be challenging for some. Despite this, the Suvony sound dampening blankets offer a comprehensive soundproofing solution with added versatility for various applications.

This set includes two large sound dampening blankets, each measuring 96 by 80 inches and weighing about 9.2 pounds, making them quite heavy and dense compared to many similar options. They're filled with 850 GSM recycled cotton and covered in thick polyester fabric, which helps absorb sound well, reducing echoes and outside noise like traffic or neighbors. The blankets come with nine grommets each, allowing for easy hanging on walls, doors, or windows using hooks or straps, which makes installation straightforward and flexible.

Their double-lock "Z" stitching keeps the filling evenly distributed and durable over time. While the product is strong in noise reduction and has a handy size for covering large areas, it does not specify any fire resistance properties, which could be important depending on your space. Also, these blankets are not water resistant, so they may not be ideal for damp environments. They can block some light as well, making them versatile for studios or rooms needing both sound and light control.

These blankets represent a solid choice for anyone looking to reduce room noise, especially in studios, offices, or home environments, with the convenience of portability and easy installation. However, if fire safety or moisture resistance is a priority, you might want to look for additional features.
