Well, I’ll walk you through 3 easy steps to soundproof the air vents present in your bedroom.

All these steps are highly effective as well as budget-friendly.

An above-door air vent is a great way to increase air circulation.

These air vents not only help to lower the temperature but also the electricity bill.

As per my knowledge, most of the rooms have these air vents as a part of interior design.

Though the air vents above the doors can be helpful in reducing the temperature to some extent still it is not something I would recommend.

The air vents allow the noise to traverse inside the bedroom leading to at least a couple of problems related to mental and physical health.

Unfortunately, the amount of noise that you’ll receive through these vents will outweigh all the benefits that it comes with, and so you don’t have any option, but to soundproof these air vents.

In fact, the soundproofing air vent is a necessity rather than a luxury.

Since you’ve landed on this post, I’m assuming that you’re looking for some cheap yet effective ways to the soundproof air vent present in your bedroom.

Correct me, if I’m wrong.

Nonetheless, I’ll walk you through the time-tested ways of soundproofing air vents without any need for professional help.

Should I Have an Air Vent in My Bedroom

Definitely, the air vent has its own PROS and CONS.

An above-door air vent helps to enhance airflow when an air conditioner or a furnace is running.

Air vent helps in maintaining the temperature throughout the room and thus, you can experience every room having the same temperature.

Especially it is important when it comes to the baby room.

The air vent keeps track that the baby room has the same temperature as other rooms in the apartment.

At the same time, these vents aren’t of much importance in the case of homes with central air, where each room is exposed to the same amount of heating or cooling.

Personally, I feel air vents are obsolete for the rooms with central air.

Guide to Soundproof Air Vents

I’ve tried to cover as much information as I can, related to noisy air vents in the bedroom.

In case, you think I’ve missed some points, then let us know in the comment section.

It will not only help us to improve the quality of the post but also, our readers.

So, without wasting any time, let’s dive deep into soundproofing air vents.

Home Renovation

Home renovation is a great way to deal with air vents. 

However, you need to be mentally prepared to spend a good chunk of money on the renovation project.

If you’re ready for the experiment then all you need to do is to replace these air vents with the drywall.

By doing so, you’ll negate any possibility of noise entering your bedroom through the vents.

I can assure you that once you’ve installed drywall, you’re completely free from all the noise issues that the vent previously presented.

The only downside of this method is that it is quite costly and a bit difficult to install as compared to other methods that we’ll discuss moving forward.

Needless to say, you’ll need to spend money on different tools, drywall, labor, and other accessories.

 With that said, renovation may be the best solution, but neither the easiest nor the cheapest solution to a noisy air vent in your bedroom. 

Block Air Vent in Bedroom

Well, blocking the air vent in the bedroom is my favorite solution.

The good thing about this method is that it doesn’t involve lots of money as well and it isn’t time-consuming.

This will help you to insulate the air vent and keep the noise away from your bedroom.

 You’ll be astonished to know that the entire process will not take more than 15 minutes. 

All you need to do is to apply some sort of sealant inside the air vent.

Though there are many options available on the market still I would like to vouch for GREAT STUFF gap filler. (Check the Current Price On Amazon)

Great Stuff is not only affordable but also blocks the external noise effectively.

You’ll get this sealant for less than $15.

So, once you have the sealant with you, all you need to do is start the process of blocking the air vents.

First and foremost, remove the cover of air vents on both sides of the vent.

Secondly, use the sealant of your choice and coat the inside of your vent.

Remember, to seal all the gaps, cracks, and holes inside as well as in the vicinity of the air vents.

Even the smallest of the holes if left open can ruin all your effort.

Finally, replace the cover of the air vent and you’re done.

Sound Maze

Needless to say, completely blocking the air vent in the bedroom is the easiest way to keep unwanted noise from entering your bedroom.

But, it comes with a cost.

It compromises the airflow capability of the air vent in the bedroom.

So, what’s the solution?

Sound Maze can help you to soundproof your vent without compromising the airflow.

This method is unique in the sense it uses layers of insulation that leave openings on the ends to allow the airflow to work well for you.

The success of this method depends to a large extent on the selection of soundproofing materials.

Using the right material to insulate the vent can help you to deaden the sound coming from the vent while maintaining a steady airflow.

What You Need

  • Foam material or acoustic cotton (Recommended: Silverstone Silent Foam)
  • 1/4 inch thick plywood
  • A ruler and a wood saw
  • A screwdriver to remove the screws on your vent
  • Wood Glue

DIY Sound Maze

If you don’t have time constraints then I would recommend you to make a sound maze on your own.

If you’ve got a busy routine and lack time for DIY projects then you can hire a soundproof consultant to do the work for you.

However, We’ll be talking about the step-by-step method to make a sound maze.

First and foremost, jot down the dimension of the inner of the air vent.

Then, cut the wood into four pieces that measure slightly less than the dimension(inside) of the air vent.

By doing so, you’ll be able to make sure that there is enough space to fit the wood inside of your vent as well as to allow air to flow through.

Furthermore, take the cotton or the foam material that you’re planning to use and wrap the wooden planks in the material.

Fix cotton or foam material to the wood using glue if needed.

Once you’re done with the aforementioned steps, all you need to do is to put some wood glue at the end of the wood plank and place the first one inside the vent.

Then, attach it to the wall of the vent using glue.

Repeat the same process with the other three pieces of wood.

 While executing the entire process, remember to glue them about half an inch apart from each other and with an opening on opposite ends that creates a zig-zag-like pattern. 

So, after completing this step, you need to replace the vent covers on the vent, and simply sit and chill.

Your hard work will be rewarded soon.

I hope this method is self-explanatory and with the options detailed above, you shouldn’t face any problem at all to block the noise out of your bedroom air vent.

It’s A Wrap

All this hard work will help you to get a sound sleep in your bedroom without worrying about unwanted noise traversing in your bedroom through the air vent.

  • The outcome of the project will depend to a great extent on the selection of the soundproofing materials as well as the method.
  • Nonetheless, any of these methods will help you to achieve sound sleep by blocking the noise from entering your bedroom.
