How Much Does It Cost To Soundproof A Room in 2021?

cost of soundproofing a room

The actual cost of soundproofing a space is different. Many factors affect the average price, including the materials needed, the room size, the labor force, and the design.

The cost of soundproofing the room varies from one hundred to one thousand. The average expense of the spectrum is only a few hundred.

Bear in mind that the soundproofing rooms is typically the most productive during reconstruction since it is added after building.

For example, soundproofing or sandstone concrete can be applied instead of using blown concrete on internal walls.

Types of Sound

When you’re planning to get soundproofing done, the first thing you need to know is the type of sounds you’re dealing with to better plan your installations. There are two types of sound that soundproofing will help you block.

1. Airborne Sound

This is the most common type of sound that we all deal with. In this case, the sound waves travel through the air alone. Popular examples of airborne sound include the noise from television, speakers, roads, and instruments.

2. Structure-Borne Sound

These types of sounds are produced during the collision of two objects. Here, the sound waves travel through the objects that strike against each other.

Why Do You Need to Soundproof Your Streaming Room?

reasons to soundproof your streaming room

Soundproofing of any stream room is essential for three reasons. Firstly it helps to prevent any outside noise from interacting with your stream.

Secondly, it tends to reduce the echo in the room you’re in and helps to enhance the ambient atmosphere, and eventually, it keeps your streams louder and thus less likely to disturb your roommates.

Soundproofing for your stream room is essential for three main reasons. Firstly it helps to avoid any outside interference from interaction with your stream.

Secondly, it tends to reduce the echo in the room you’re in and helps to enhance the ambient atmosphere, and eventually, it keeps your streams louder and thus less likely to disturb your roommates.

All soundproofing space only makes for a smoother stream of sound. When someone cries in another room, it would be much harder to understand in either a soundproof room than in a non-soundproof room.

When you’re about to get serious about streaming, you want to have a professional, knowledgeable voice.

Besides, anybody who has tried to capture decent audio quality will know, nothing worse than background sound, which you can’t get away with within a stream.

However, if you’re broadcasting online, you don’t have time to tidy it up, waste hours on audio apps.

Common Types of Soundproofing Methods

Soundproofing is a science, so no matter what material you’re using, it’s actually the method and technique that make all the difference. Below are a few standard methods of soundproofing. 

1. Adding Mass & Density

The easiest and most common soundproofing method is to add mass and density. Sound waves generally travel slower and with reduced intensity when the medium of travel is highly dense. That’s the principle which is used in this method.

This method generally uses soundproof panels and other covers to block sound. These panels and sheets are made of such thick and dense material that the sound waves have trouble passing through it and lose their energy on the way.

2. Damping 

Damping is applied to prevent resonance. Sometimes the frequency of the sound waves can match with the natural frequency of the medium they’re passing through, resulting in a phenomenon called resonance. In this phenomenon, when the two frequencies mentioned above match, the volume of the sound goes dramatically high.

The purpose of damping is to reduce the chances of a resonance. This is done by disrupting the vibrations and dissipating them before they can create a resonance. Here as well, soundproof panels are used to dampen the frequency of the sound waves.

3. Absorption

When there’s an air cavity or empty space available, the sound waves vibrate and produce a louder noise. In this method, these sound waves are absorbed, and their energies are reduced through internal friction to lower the sound.

Again, the sheets and panels made of soundproofing materials are used to absorb sound. For example, imagine a conch. When you blow into a conch, the hollow space in between creates a loud noise. Similarly, when soundwaves enter a hollow room, the intensity and volume of the sound rise owing to the higher rate of reflection. 

However, if you use sound-absorbing materials, their energies will be absorbed before they can vibrate, and that’s how absorption helps in blocking sound.

4. Decoupling

Decoupling is the process of disrupting the path of sound to reduce noise. Sound always needs a medium to travel; it cannot travel in a vacuum. So when you remove the medium of travel from its path, it creates a disruption and stops the sound waves from propagating further.

For example, sound-proof windows have a layer of vacuum between the two panes of glass. When the sound travels from one pane to another, the vacuum in between stops its propagation and locks it out.

Cost of Room Soundproofing

The total cost of soundproofing the room differs. There is a range of products that influence the average price.

It includes the materials required, the design of the place, labor, and the design size.

The cost of soundproofing the room varies from a hundred to a thousand. The total amount within the spectrum is a couple of hundreds.

Bear in mind that perhaps the soundproofing rooms are typically the most efficient during building after renovation.

For example, it is possible to incorporate soundproofing or rock-wool installation instead of blown concrete on internal walls.

Soundproofing is a costly process. There seem to be a range of inexpensive solutions you can use, but the terms “cheap” and “soundproofing” don’t always go along.

These are the most commonly used materials and their respective price ranges.

  • Acoustic tiles protect walls and floors that are used to kill sounds. They regularly cost a hundred per tile and the measurement  20×20 inches per tile.
  • Acoustic foam panels are a material that is attached to walls to help withstand sound. Costs differ depending on the amount and quantity of the items bought. Usually, they come in boxes for a hundred per panel.
  • Blown insulation is often considered a “loose-fill” composed of reduced cellulose fiber that helps reduce the propagation of sound waves. It cost between a hundred to thousand.
  • Soundproof drywall is a melodically strengthened gypsum board that costs thousand per sheet. Besides, standard drywall costs a hundred per sheet.
  • Folding a flooring system and carpeting tends to trap sound. Depending on the content you’re using, it’s a hundred to thousand.
  • Soundproof covers and wall mountings by installing curtains or lights can help to minimize noise transmission. The amount is reasonable, so you should plan to pay less than a hundred per meter.

Hiring Contractor

Hirer or employ a contractor that knows how to make the Montréal, Laval, and North Shore space soundproof.

Ensure you hire a contractor that specializes in walls, floors, or ceilings soundproofing, and soundproof doors.

You will reduce the amount of noise in your house or apartment.

If it’s the noise of automobiles outside of the movements upstairs, there are a range of options available to enhance the soundproofing of your home.

Here are solutions to help you soundproof your home:

  • Ceiling soundproofing as the sound passes through the air. The cracks in the ceiling enable the sounds from the top floor to filter through. You may use these small gaps to reduce the propagation of noise. Another approach you can recommend is blowing cellulose as an inexpensive and sound-absorbing material directly through the roof.
  • Wall soundproofing is the basic concept of soundproofing walls to cover cavities to decrease the propagation of sound. For that purpose, the injection of cellulose or rock wool and behind walls tends to reduce noise.
  • Floor soundproofing is preferable, an aspect that should be addressed when constructing a new home or apartment building. The construction company will install an acoustic membrane underneath the building, which will act as a sound display amongst the floors.
  • A soundproof door is a sturdy or padded door that has improved sound protection. In fact, for purposes of thermal conductivity and safety, the Building Code advises the construction of this sort of door in between the actual house and the home.

DIY Soundproofing

Our houses are meant to be a quiet, relaxing respite from the sights and sounds of the outside environment.

But it’s getting hard when the area gets busy and noisier throughout the day, especially if you’re still working at home and want some silence to do something.

For muting the noise, you will effectively diminish the traffic meeting rooms, sirens, aircraft, beeping horns, and other disruptive intrusions.

That takes place in or around your house, particularly since you’re not a lover of wearing noise-canceling your headphones the whole day.

Here, we’ll provide comprehensive details on connections between neurons to soundproof the room, along with some extremely suggestions and specialized strategies that use sound-absorbing materials.

Are you involved in more DIY improvements? We’ve already covered you! Here are a few suggestions:

Door Weather Stripping

Usually, doors and windows don’t have weather protection, but installing a few along the edge of the doorway might help muzzle sounds.

Peel-and-stick soft foam protective sealing provides a  strong seal and is cheap and easy to apply.

Felt is among the oldest forms of climate sealing, comes in big rolls with or without appropriate thickness, not expensive, and highly efficient in preventing noise.

You may also mount a door material sweep or door shutter to the bottom door to cover the space gap under the door.

Wall Hangings

Hard materials, such as plasterboard, concrete, drywall, and tile, reflect and intensify sounds. It just makes sense, then, that soft surfaces trap noises, making rooms even louder.

Cover walls with heavy blankets, shifting mats, tapestry, or quilts. Practically any soft plastic will work, while thicker materials will produce more sound than thinner material.

If you wouldn’t mind bringing an industrial feel to space, attach the sound-absorbing boards to the walls and, if required, to the roof.

The board panels are made of excellent noise-damping materials, including soft foam rubber, thick polyester fiber, and wood.


Sound doesn’t just echo off the bricks and can even be mirrored in hard surfaces. If your bedroom has hard-surface flooring made of tiles, wood, or plasterboard, the best option would be to lay down a carpet rug to help you reduce noise.

Although, dense carpets are safer than thin carpet rugs. Also, purchase extra thick padding for better sound insulation under the couch.

Absorb Vibrations

Noise is created by vibration. Thus, any roaring piece of equipment or machinery generates sounds that can send noise to neighboring spaces.

It contains products such as headphones, furniture, weight machines, and stationary bikes.

To soften the sounds and silence the room, place the item on a thick piece of heavy foam rubber, such as a home-bath mat and a horsehair mat.

To Soundproof A Room

Demolishing old walls and restoring involves more money, takes more time, and requires more space as well. Soundproofing is always worth the money, and there’s no reason to go excessive.

If you plan to spend just one wall on soundproofing, it could benefit a little bit. But your bed won’t be fully soundproofed.

In attempting to save some money, you’re going to end up costing it because you have to completely re-build the house.

Since going to the hassle of tearing down that wall by applying for additional protection, you might as well go the extra mile by putting the sound padding on the light fittings and the extension cords along the side of the room so that the sound can’t travel outside.


As we’ve already mentioned many times, the price of soundproofing can vary considerably, based on many different aspects.

To decide what this project would cost you, make sure you get a quotation from a contractor and describe your precise objectives.

If you suggest that you’re doing the job yourself, the expense would be lower with the different materials that you need when you start constructing.
