Soundproofing blankets are highly effective, affordable methods to reduce noise disturbances in a variety of environments. As opposed to the costly and time-consuming method of installing soundproof materials into walls or flooring, soundproofing blankets can be hung or draped to provide a temporary, movable, or easy-to-adjust noise barrier.
A Deep Dive into Soundproofing Blankets’ Functionality
Soundproofing blankets, also known as moving blankets or acoustic blankets, are made of dense, sound-absorbing materials like fiberglass. They are often quilted for added thickness and effectiveness. The dense material helps to prevent sound waves from passing through, thereby reducing the overall noise level.
There are two methods in which a soundproofing blanket functions: sound absorption and soundproofing. Sound absorption is the process of transforming sound energy into heat energy, and the thick material of these blankets is perfect for this function. On the other hand, soundproofing involves blocking sound waves from passing through entirely, which is what the dense material does effectively.
Best Materials for Soundproofing Blankets
Several materials are used in manufacturing soundproofing blankets, each providing a different level of sound reduction. Here are the most commonly used materials:
• Fiberglass: Fiberglass is known for its excellent sound-absorbing quality paired with fire resistance. Its fibrous structure traps sound waves, converting them into heat.
• Mineral Wool: Another fibrous material, mineral wool is adept at absorbing sound but is not as fire-resistant as fiberglass.
• Cotton: While not as effective as fiberglass or mineral wool, cotton is a cheaper option that still provides moderate soundproofing capabilities.
Making Your Own Soundproofing Blanket: A DIY Approach
If you want a customized solution on a budget, you can create your own soundproofing blanket using materials commonly found at home or readily available from local stores.
• Gather Your Fabric Choice: The two best options for DIY soundproofing blankets are mass-loaded vinyl (MLV) and moving blankets. MLV is a dense material that is thin and versatile, making it a prime candidate for effective soundproofing. Moving blankets are also ideal due to their quilted applications that dampen sound effectively.
• Measure and Cut: Measure the doorway, wall, or window where you plan to hang the blanket and cut the fabric accordingly. Ensure you leave an extra few centimeters on all sides to account for inaccuracies.
• Add Layers: If you’re using MLV, consider adding more layers for better soundproofing. For moving blankets, one layer should be enough.
• Secure the Edges: Using strong thread, stitch the edges to prevent fraying. Ensure the stitches are strong and durable.
Hanging Your DIY Soundproofing Blanket
The key to securing a soundproofing blanket is to cover the entire surface. Hanging methods may vary depending on the attachment surface:
• For Doors and Windows: Use hooks or curtain rods to hang the blanket. Ensure the blanket overlaps the frame to effectively block sound.
• For Walls and Ceilings: Nails, thumbtacks, or adhesive hooks can be used. Again, ensure there is overlap on all sides.
Optimizing Your Blanket’s Soundproofing Capability
While hanging a soundproofing blanket can indeed reduce the level of noise, there are ways to optimize its effectiveness. Here’s how:
-
Use Multiple Blankets: If possible, use multiple blankets to create a thicker soundproof barrier.
-
Create an Air Gap: An air gap between the blanket and the wall can further reduce sound transmission.
-
Combine with Other Resources: Pair your soundproofing blanket with other soundproofing techniques such as using foam panels or noise-reducing curtains.
Evaluating Effectiveness
The effectiveness of a soundproofing blanket, DIY or otherwise, will depend on many factors. These include the type of noise, the original and target sound levels, and the installation’s accuracy. Therefore, a trial-and-error approach might be necessary to achieve optimal results.
To evaluate, you can use a decibel meter. These devices measure the sound level in the environment. By taking readings before and after the implementation of the soundproofing blanket, you can compare to gauge the effectiveness of your setup.
In Conclusion
Soundproofing blankets provide a cost-effective, easy-to-use solution for noise reduction. Even better, they allow for a DIY approach where you can tailor the solution to your specific needs. While not as effective as in-built soundproofing, these practical tools can significantly improve your living or working environment’s noise levels. As you embark on your DIY journey, remember that the effectiveness will rely heavily on meticulous installation and the selection and use of the right materials.
