Does Putting A Blanket Under A Door Reduce Sound?

Most houses today have sound leakage problems with their doors, particularly those that are placed in crowded urban areas. As a result, people are searching for ways to reduce the amount of noise that enters their homes or workplaces. One of the simplest and fastest solutions is placing a blanket under a door to reduce sound.

The idea is that the blanket will act as a barrier, preventing noise from passing through the gaps under the door. While some claim that this method works, others don’t think so. In this article, we’ll explain everything and tell you how to get the best possible results. So, let’s start!

Does Putting A Blanket Under A Door Reduce Sound? Yes, placing a blanket under a door can help reduce the sound that travels through the gap under the door. The blanket acts as a barrier and absorbs some of the sound waves, but the effectiveness depends on the thickness and material of the blanket, as well as how well it fits under the door.

While placing a blanket under a door will not completely block the sound, it can make a noticeable difference in reducing noise levels. When soundproofing a room in your home, it’s important to remember to soundproof your doors, also.

The door is usually the weak point, making it a critical element of any soundproofing project. We will discuss this topic in more detail below, so stay tuned.

Why Is It Important To Soundproof a Door?

Soundproof a Door

If you’ve ever wondered why noise from outside your room seems to seep through the door, the answer is that the doors are often the biggest culprit for noise issues. This is particularly true for the gap around the door, especially the larger one at the bottom.

The good news is that soundproofing your door can solve these problems and provide other benefits. For instance, it can help insulate your room from temperature fluctuations, and it can lead to improved air quality and comfort. If you’re looking for a quieter, more comfortable room, soundproofing your door is a great place to start.

Placing a blanket under the door will not help you to reduce the loud sound and is also not a long-term solution. Therefore, to soundproof your door, opt for a long-term solution.

5 Ways To Soundproof Your Doors

Soundproofing doors can be very tricky, and it may require extensive modifications to the door frame and heavy construction work. The door weight and components can range from 200 to 600 pounds (90 to 250 kg), making it a challenging and costly option for most people.

Furthermore, investing in a soundproof door can be very expensive for those on a tight budget. Fortunately, there are some affordable and effective ways to soundproof your doors without breaking the bank.

These alternative methods can help you achieve the desired level of sound insulation for your door without requiring too much time, money, or effort. Here are five ways how you can soundproof your interior doors:

1. Install Soundproofing Rubber Around Your Door

If you’re new to the world of home improvement and don’t have much space around your door, soundproofing rubber might be the perfect solution for you. This is a highly effective method for minimizing sound transfer and can make a huge difference in the soundproofing of your door.

So, if you’re looking for a simple and effective soundproofing method, consider installing a soundproofing rubber around your door. Here is how you can do it:

  • Step 1: The first step is to remove molding before installing a rubber. This can be done using a pry tool, and it will give you access to the edges of the door, where you can add soundproofing rubber.
  • Step 2: Now, add a soundproofing rubber when you remove the molding. Be sure to install the rubber around the edges of the door. This dense material will help to prevent noise from escaping or entering the room through gaps around the door.
  • Step 3: Lastly, seal small gaps and cracks to enhance the soundproofing effect further, and add acoustical caulk to fill in any gaps or cracks around the door frame. This will provide maximum sound protection and minimize noise transfer between rooms. You can easily identify these gaps by turning off the light and looking for any areas where outside light is visible.

As mentioned, placing a blanket under a door is not a permanent solution and does not offer a good result in soundproofing.

2. Add Weatherstripping

When installing soundproofing rubber, filling gaps that are between the door and its frame is very important. An effective way to achieve this is to apply it to weatherstrip. This way, you will achieve better sound insulation. Weatherstrip is usually used to insulate windows and doors from the outside elements.

To achieve long-term noise reduction benefits, opt for quality weatherstripping instead of the basic ones that tend to wear out over time. It is crucial to exert sufficient pressure when applying weatherstripping on your door for better results.

3. Install A Door Gasket

If you’re looking for a better quality solution than weatherstripping to seal the gaps between your door and the frame, door gaskets are the way to go. Although they are a little more expensive, door gaskets are a good investment because they provide a more durable and long-lasting solution. These gaskets are usually made of neoprene.

Additionally, adaptable door gaskets are available on the market, which is especially helpful since doors can often become warped or not fit perfectly into the frame. You can fine-tune the fit with adjustable gaskets to close the hatches.

4. Install A Door Sweep Under A Door

When it comes to soundproofing your door, installing a door sweep is one way you should not ignore. Many doors have a sizable gap at the bottom, allowing significant amounts of sound to leak, even if you’ve added gaskets or paneling to the door.

Installing a door sweep can effectively close this gap and impede the transmission of sound waves. While this may require some effort and the use of a drill and screws, this investment in soundproofing is worth the effort. So, install a door sweep at the bottom of your door to prevent sound leakage and achieve maximum sound protection.

5. Consider Automatic Door Sweep

For an even more effective soundproofing solution, you might want to consider installing an automatic door sweep. While the door is open, the sweep remains suspended above the floor to allow unrestricted movement. However, when your doors are closed, it lowers to form a firm and seal with the floor, effectively blocking any sound leakage.

This automatic process ensures that the gap at the bottom of the door is always tightly sealed, even when you forget to close the door fully. While installing an automatic door sweep might require more effort and expertise, it can provide a superior soundproofing effect that is well worth the investment.

FAQ: People Also Ask

Do blankets suppress noise?

Yes, moving blankets or fabric blankets can absorb sound in places like makeshift recording studios or band rooms. However, they are ineffective at completely blocking noise and should not be used for that purpose. Instead, they are best suited for providing some degree of sound absorption.

How can I soundproof a room cheaply?

If you’re looking to soundproof a room cheaply, one of the most cost-effective methods is to use thick blankets and quilts. Cover doors, walls, or windows with blankets to block out external noise. To contain sound within a room, hang blankets properly on each side of the doors or inside walls.

How much sound do blankets absorb?

The efficiency of a sound-absorbing blanket cannot be guaranteed to block out sound completely. However, it is expected to absorb sound levels by a range of 30 to 80 percent.

Final Thoughts

In conclusion, placing a blanket under a door may reduce the sound that passes through the door. Still, the effectiveness of this method will depend on several factors, including the type of blanket used and the size of the gap under the door. While this is a quick and easy solution to reduce the noise under the door, it may not be effective in all cases, especially for loud sounds.

If you are looking for a more effective solution to reduce sound, you may want to consider other options such as installing weatherstripping, soundproofing rubber, using door sweeps, or even considering instlaling door gaskets.

It is important to consider the specific circumstances and factors at play and to explore a range of options to find the most effective solution for reducing unwanted noise.
