You’ve probably heard about soundproofing blankets, those handy innovations designed to keep your surroundings quiet by absorbing unwanted noise. This article is a comprehensive examination of whether soundproofing blankets really do deliver on their promise.
It’s an insightful read that dissects how they work, what they’re capable of, and if they’re worth the investment for noise reduction in your space. Let’s unpack the intricate details behind soundproofing blankets and determine their efficacy for you.
Understanding Soundproofing
What is soundproofing
Soundproofing is the practice of reducing or eliminating the audible noises in an area. It is often used to create quiet environments for work, leisure, or privacy. Depending upon the surrounding noise levels, the requirement for soundproofing can range from minimal to extensive.
Principles of soundproofing
Soundproofing is based on four main principles: absorption, damping, decoupling, and mass. Absorption uses materials that soak up the sound waves, converting them into heat energy.
Damping refers to the reduction of resonation in a structure or object, which can help to minimize noise. In decoupling, two structures are separated to stop the transmission of sound between them. Lastly, mass is used to create a dense barrier that is difficult for sound to penetrate.
Types of soundproofing
There are many different types of soundproofing techniques, ranging from simple to complex. These include installing acoustic panels, foam, or insulation in walls, ceilings, or floors; using noise-cancelling headphones or earplugs; and even building specific soundproof rooms. They differ in the level of noise they block and the type of noise they’re effective against.
Introduction to Soundproofing Blankets
What are soundproofing blankets
Soundproofing blankets are a form of noise reduction tool that are made of thick and dense material. These heavy-duty blankets are designed to absorb sound waves, making them an inexpensive and easy way to reduce unwanted noises.
Materials used in soundproofing blankets
Soundproofing blankets are typically made from materials that are good at absorbing sound or blocking it from penetrating through.
Common materials include fiberglass, mineral wool, and thick, dense fabrics. The material used can greatly affect the effectiveness of the blanket at reducing noise.
Types and varieties of soundproofing blankets
There are various types of soundproofing blankets to cater to diverse needs. Some are designed to be hung on walls or doors, others are used to cover windows, and there are also portable ones for temporary use.
The type you choose will depend on your specific needs and the source of the noise you wish to mitigate.
How Do Soundproofing Blankets Work
The science behind it
The science behind soundproofing blankets is based on the principles of soundproofing mentioned earlier. The dense material of the blanket absorbs the energy from the sound waves, reducing their power.
The extensive fibers within the blanket material also scatter the sound waves, further reducing their intensity.
Sound absorption vs soundproofing
There’s a key distinction between sound absorption and soundproofing. Absorption deals with the echo within a room, reducing reverberation and creating better sound clarity, while soundproofing blocks sound from either entering or exiting a space. Soundproofing blankets can serve both purposes to some extent.
Effectiveness of different materials
The effectiveness of soundproofing blankets can widely depend on the materials used in them. Dense materials like fiberglass and mineral wool are exceptional at absorbing and blocking sound waves.
The thicker the material, the more sound it can block, but this would have a trade-off in terms of weight and portability.
Combating Different Types of Noises
Addressing airborne noise
Airborne noise, as the name implies, is noise that travels through the air. It includes most typical noises like conversations, TV sounds, and music. Soundproofing blankets can be quite effective at mitigating these noises, especially when they effectively absorb high frequency sounds.
Dealing with impact noise
Impact noise is created when an object strikes another object, like footsteps on a wooden floor. Since impact noise can cause vibrations, it’s more challenging to manage.
Soundproofing blankets can help to some extent, but they might not be as effective as more robust methods like floating floors or decoupled walls.
Soundproofing against vibrational noise
Vibrational noise, similar to impact noise, travels through structures and objects. Appliances, HVAC units, or machinery often cause this type of noise.
Once again, while soundproofing blankets can aid in lessening it, they might not be as efficient as other options like vibration absorbing pads or mounts.

Applications of Soundproofing Blankets
Domestic use
In homes, soundproofing blankets can be used in many ways. From hanging them on noisy doors or windows, to using them as a temporary measure for reducing noise during parties or other loud events, they offer a practical and cost-effective solution.
Professional recording studios
In professional recording studios, soundproofing is integral. Soundproofing blankets can be a great addition, especially for absorbing echo and improving sound clarity. They also offer portability, which can be highly beneficial in a studio setting.
Industrial applications
In noisy industrial environments, soundproofing can increase productivity and safety. Soundproofing blankets can be used to partition areas, wrap around noisy equipment, or hang on walls to help absorb the excessive noise.
Vehicle-related uses
For trucks, RVs, and other vehicles, noise from the engine or the road can be a nuisance. Here, soundproofing blankets can be used to wrap around noisy areas, improving the overall driving or riding experience.
Installation of Soundproofing Blankets
How to install soundproofing blankets
Soundproofing blankets are easy to install. Primarily, they can be hung over doors, windows, or walls using grommets, clips, Velcro, or even heavy-duty nails. Each situation will require a slightly different approach, so it’s best to follow the manufacturer’s instructions.
Tips for maximum effectiveness
For maximizing their effectiveness, ensure the blankets cover the noise source completely. The more of the blanket that comes in contact with the sound waves, the better it is. Multiple layers of blankets can also provide more soundproofing.
Things to avoid while installing
Avoid hanging the blankets loosely as that might allow noise to pass through. Also, avoid blocking ventilation, emergency exits, or anything that may cause potential hazards. Proper care should be taken during installation to ensure the safety and effectiveness.

Comparing Soundproofing Blankets with Other Soundproofing Methods
Comparing cost-effectiveness
Compared to other soundproofing methods, soundproofing blankets are generally more cost-effective, especially considering their portability and ease of installation.
Full-scale solutions like acoustic panels or underfloor insulation might offer superior noise reduction, but they also come with higher costs and installation hassles.
Comparing installation ease
Soundproofing blankets are without a doubt, easier to install than most other soundproofing methods. They are portable, require minimal physical effort and can be moved around as needed without much trouble. This can be a significant advantage for renters or temporary noise scenarios.
Comparing effectiveness
In terms of effectiveness, soundproofing blankets can compete with more mainstream solutions, especially for high frequency noises and echoes. For low-frequency impact or vibrational noise, other methods might have the upper hand.
Potential Drawbacks of Soundproofing Blankets
Issues with aesthetics and design
