Whether you live in a high-rise apartment or a sprawling suburban home, soundproofing can be an issue that affects all home types. You may be addressing exterior noise, like traffic and outside businesses, or interior noise, like loud neighbors or noisy kids.

Cheapest way to soundproof a room

Regardless of your exact arrangement, finding the cheapest way to soundproof a room can be a quick and effective way to get some peace and quiet. There are many easy ways to soundproof a room that don’t involve holes in an existing wall or permanent fixtures. 

How to Make Your Room Soundproof from Inside

When you’re starting to consider soundproofing a room, location is everything. Making your room soundproof from inside isn’t as hard as you might imagine. There are three critical points that can make a room feel noisy, so be sure to address each location to truly soften the noise in your space.

  1. Source of the sound
  2. Entry point
  3. Reflection point

Sound Reflection Basics – best places to soundproof

1. The source of sound

Is it one specific noise that you’re trying to conceal, like a television, instrument, or traffic? This type of sound can generally be contained to one specific spot. The first step to concealing the sound is toidentify the source.

2. Entry point

The entry point is the area in your space where the sound enters your room. Again, this may be an exact point that is adjacent to the source of the sound or it could be an entire existing wall, like in the case of shared walls in apartments, condos, or duplexes.

Exterior windows are also common entry points for unwanted noise.

3. Reflection point

After the sound enters your space, it will reflect back at the same angle of entry. In the example below, this might lead you to do soundproof techniques on the headboard wall as well as the wall at the end of the footboard.

Since the angle of entry is a straight line in this case, the sound will likely bounce back and forth between the headboard and footboard until it dissipates.

Below we will go over different methods of cheap and easy ways to soundproof a room from inside. For effective sound masking, you will want to implement soundproofing techniques at all three of the points listed above.

Cheap Ways to Soundproof a Room

One of the easiest ways to mask unwanted sound in a room is to  add furniture and natural decor to your space. Sound bounces off of hard surfaces, like hard flooring or blank existing walls. To kill sound in its tracks, consider adding finishes that the sound can be absorbed into. Here are three of the cheapest ways to soundproof a room using furniture and decor.

Use curtains and window treatments

Not only do curtains serve as a great visual barrier against nosy neighbors, but it offers dual purpose sound dampening as well. Hanging plush, thick drapery helps to absorb extra sound from the outside as well as unwanted traffic noise. On the inside, these same curtains help to absorb ambient noise that floats around the interior of the space.

Add area rugs

To mask sound coming from lower neighbors in an apartment situation, consider adding thick area rugs to your main living spaces. Adding a pad under the rug is another way to enhance the sound masking, without taking up additional square footage.

Add upholstered furniture

Adding upholstered furniture to your space gives more areas for sound to be absorbed into, and keeps it from bouncing as much. If you don’t have room for more furniture, try adding thick blankets or plush throw pillows to your existing areas.

Soundproofing a room from the inside is all about dampening noises by targeting them at the entry or reflection point.

How to Soundproof a Room for Free (with Blankets)

Speaking of blankets, if you don’t have the budget to buy extra sound dampening furniture, curtains, or rugs, you can use blankets as a free soundproofing alternative.

  1. Get Blankets – Gather up all of the blankets and quilts you have around your home. Remember, the thicker, the better!
  2. Sound In or Out? – Decide if you are trying to keep sound in (i.e., sound that you’re making) or keep sound out (sound that’s coming from the outside)
  3. Sound In – If you want to keep the sound in, you’ll need blankets on all sides.
  4. Sound Out – If you want to keep the sound from the outside out you’ll need to put blankets over the source of those sounds. Most likely, that means a specific wall, door, or window.
  5. Affix to Wall – In both cases, you’ll want to hang the blankets using tacks, finishing nails, or screws, depending on how heavy they are.

Affixing a blanket to a wall, window, or doorway can help to dampen sounds

In addition to your blankets, if you have any large pieces of furniture in your room, you can position those against the appropriate existing wall to help minimize sound. Bookcases and headboards work great for this.

Best Ways to Soundproof a Room

Have a bigger problem and added furniture just isn’t cutting it? For especially noisy neighbors, kids in the band, or housing directly adjacent to high-traffic areas, you may way to consider a more powerful solution.

If you aren’t on a tight budget, check out this guide by HouseLogic.com. Or if you want to tackle your soundproofing project at the construction level see here.

However, if you are on a budget, continue reading below. The following solutions may not be as cheap or dual purpose as those mentioned above, but they are more effective at soundproofing a room, regardless of what the source of sound is.

Hang acoustic panels

Depending on the size and quality, hanging acoustic panels can be quite expensive, but it’s certainly one of the best ways to soundproof a room. Acoustic panels are excellent at absorbing unwanted sounds and you can hang them like art or accents around your room or apartment.

These panels are generally pretty lightweight and come in a variety of colors to match your decor. Inexpensive acoustic panels, like these foam panels, are easy to install and help to absorb unwanted sounds.

Properly positioned acoustic panels can stop noise from reflecting and dampen noise.

For a little extra cash, there are larger acoustical panel sizes available that are generally installed with heavy duty hardware or flush mounted z-clips. These can be connected to make a single large panel or used independently.

Want to use panels, but aren’t sure where to hang them?

As a general rule of thumb, you want to place panels on the opposite wall of the source of sound for the maximum absorption.

Sound reflection follows the same laws as light reflection and bounces back at an angle equal to the angle of the incoming sound.

Cheap Soundproofing Foam

If you’re on a tight budget, you can accomplish great things with cheap soundproofing foam. In recent years, soundproofing foam has come a long way, and it’s incredibly cheap on Amazon.

For usually around $10-$20 you can find cheap soundproofing foam. Better yet, you can usually soundproof foam in a variety of colors, so it doesn’t have to be purely functional. You can add a nice aesthetic touch to your room, while also achieving your soundproofing needs.

Use a sound booth

If you’ve got a higher budget and can identify the source of sound within your home, you may want to consider using a sound booth. This helps to isolate the sound before it has a chance to bounce around your space.

An example of this type of solution would be this customizable sound booth. Depending on the size, a sound booth can range from $50 up to $2,000 or more.

Easiest Way to Soundproof a Room

If you’re trying to soundproof a room, chances are that you may be looking for something that is just plain easy. In many cases, people wanting to soundproof a roof are in temporary living situations (like apartments or rentals) and can’t spend a lot of time or money on complicated strategies.

In other cases, the annoying sound is actually temporary, like construction work or a neighbor’s noisy project. One solution for these types of annoying noises is adding a little background noise.

Soundproofing Alternatives (add background noise)

Adding background noise is an incredibly easy way to soundproof a room— and it’s inexpensive also. Playing relaxing instrumental music or even getting a sound machine are great ways to add a little white noise to your space.

When there’s something else to listen to, it becomes easier to drown out the more annoying sounds, even if they’re still there. The Sound + Sleep sound machine, for example, has 10 different sounds it can play, including white noise, nature, or even sounds of a bustling city.

If you prefer a more muted sound like a fan, check out the Marpac Dohm sound machine, which simply plays varying intensities of fan sounds. While sound machines don’t remove the noise entirely, they are easy way to mask annoying noises and can be especially useful for temporary situations.
