Soundproofing Your Home: Using Acoustic Blankets on Walls and Doors

Overview

Living with misophonia and sound sensitivities can make everyday noises feel overwhelming. One effective way to reduce unwanted sounds in your home is by using acoustic blankets on walls and doors. Acoustic blankets are thick, dense materials designed to absorb and dampen sound waves, preventing them from echoing and reverberating through spaces. By strategically placing these blankets, you can create a quieter, more comfortable environment.

In this guide, we'll walk you through the process of selecting, installing, and maintaining acoustic blankets to help you soundproof your home effectively.

  • Difficulty: Easy
  • Cost: Medium

Step-by-Step Instructions

Materials and Tools You'll Need

  • Acoustic blankets (also known as soundproofing blankets or moving blankets)
  • Measuring tape
  • Marker or pencil
  • Heavy-duty adhesive hooks or wall anchors with screws
  • Grommet kit (if blankets don't have grommets)
  • Drill (optional, if using wall anchors)
  • Hammer and nails (alternative to hooks or anchors)
  • Ladder or step stool
  • Level

Step 1: Assess the Space

a. Identify Problem Areas

Start by identifying the walls and doors where noise transmission is highest. Common areas include:

  • Shared walls with noisy neighbors
  • Walls facing busy streets
  • Doors leading to high-traffic areas

b. Measure Surfaces

Use a measuring tape to determine the dimensions of each wall and door you plan to cover. Write down the measurements to ensure you purchase the correct size and number of acoustic blankets.

Step 2: Select the Right Acoustic Blankets

a. Choose the Appropriate Size

Select blankets that are large enough to cover the entire surface area of the walls and doors. Oversized blankets can be trimmed if necessary.

b. Consider Material and Thickness

Look for blankets made specifically for sound absorption. Thicker blankets with higher density provide better soundproofing. Common materials include:

  • Polyester blends
  • Fiberglass core blankets (for enhanced absorption)

c. Check for Grommets

Grommets are metal rings that reinforce holes in the fabric, making it easier to hang the blankets. If the blankets don't have grommets, you can install them yourself using a grommet kit.

Step 3: Prepare the Acoustic Blankets

a. Add Grommets (If Necessary)

If your blankets lack grommets:

  1. Mark the Grommet Locations

    • Lay the blanket flat on the floor.
    • Use a marker to mark spots along the top edge, spacing them every 18-24 inches.

  2. Install the Grommets

    • Follow the instructions on your grommet kit.
    • Position the grommet pieces on either side of the fabric at each mark.
    • Use the provided tool to hammer the pieces together, securing the grommet.

Step 4: Install Hanging Hardware

a. Choose Your Hanging Method

Depending on your wall or door material and whether you can make permanent changes, select one of the following:

  • Adhesive Hooks

    • Ideal for renters or temporary setups.
    • Ensure the hooks can support the weight of the blankets.

  • Wall Anchors and Screws

    • Provide a more secure and permanent solution.
    • Suitable for heavier blankets.

  • Nails

    • A simple method but may leave small holes.

b. Install the Hardware

  1. Mark the Positions

    • Use a level to draw a straight line where the top of the blanket will hang.
    • Mark spots corresponding to the grommet locations on the blanket.

  2. Attach the Hardware

    • For Adhesive Hooks:

      • Clean the wall surface with rubbing alcohol.
      • Peel the backing and press the hooks firmly into place.
      • Wait as per the manufacturer's instructions before hanging anything.

    • For Wall Anchors and Screws:

      • Drill pilot holes at each mark.
      • Insert the wall anchors.
      • Screw in the screws, leaving enough head to hang the grommets.

    • For Nails:

      • Hammer nails into the wall at each mark, leaving enough exposed to hang the blanket.

Step 5: Hang the Acoustic Blankets

a. Start from One Side

  • Begin hanging the blanket by placing the first grommet over the corresponding hook, screw, or nail.

b. Proceed Across the Wall or Door

  • Continue attaching each grommet in order, ensuring the blanket hangs straight.
  • If using a ladder or step stool, exercise caution and have someone assist you if possible.

c. Smooth Out the Blanket

  • Once hung, smooth out any wrinkles or folds.
  • The blanket should hang flat against the wall or door for maximum effectiveness.

Step 6: Secure the Edges (Optional)

For enhanced soundproofing:

a. Attach the Sides and Bottom

  • Use additional hooks or nails along the sides and bottom edges.
  • This creates a sealed barrier, reducing gaps where sound can pass through.

b. Use Velcro Strips

  • Apply adhesive Velcro strips to the wall and corresponding spots on the blanket.
  • Press together to secure the blanket tightly against the surface.

Step 7: Repeat for Additional Areas

  • Install acoustic blankets on other identified walls and doors following the same steps.
  • Ensure all blankets are hung securely and cover the intended areas fully.

Step 8: Test the Effectiveness

a. Listen for Improvements

  • Spend time in the room to notice the reduction in noise levels.
  • Pay attention to common triggers and assess if they are less pronounced.

b. Make Adjustments if Necessary

  • If certain areas still allow noise through, check for gaps or loose sections.
  • Consider adding additional blankets or overlapping them for increased absorption.

Step 9: Maintenance

a. Cleaning the Blankets

  • Vacuum the surface periodically to remove dust.
  • For washable blankets, follow the manufacturer's cleaning instructions.

b. Inspect Hanging Hardware

  • Regularly check that hooks, screws, or nails remain secure.
  • Tighten or replace hardware as needed.

Step 10: Additional Tips

a. Layering Blankets

  • For significant noise reduction, hang multiple blankets together.
  • Stagger the seams to cover any gaps.

b. Combining with Other Soundproofing Methods

  • Use acoustic blankets in conjunction with:

    • Weatherstripping around doors and windows
    • Installing door sweeps
    • Adding rugs or carpets to floors
    • Placing bookcases or heavy furniture against walls

c. Aesthetic Considerations

  • Choose blankets in colors or patterns that complement your decor.
  • You can also cover the blankets with decorative fabric or curtains for a more polished look.

Conclusion

Using acoustic blankets on walls and doors is an effective and accessible solution for reducing unwanted noise in your home. This simple DIY project can make a significant difference in creating a peaceful environment that accommodates sound sensitivities. With moderate investment and minimal effort, you can enjoy a space that feels more comfortable and conducive to relaxation.

Remember, the key to successful soundproofing is attention to detail and ensuring all potential sound paths are addressed. Don't hesitate to combine this method with other strategies to achieve the best results.
