The most crucial matter that worries us before soundproofing rooms is: how much does it cost to soundproof a room?

There are various soundproofing companies that provide this service, but in this article I will concentrate on doing the job as a do-it-yourself project.

This article provides some information on the soundproofing costs and various options with different prices for you to determine the method that best fits your budget.

To soundproof a room, how much does it cost?

The cost of soundproofing will vary from a few bucks to thousands of dollars, depending on the attributes of the material, the size of the room, and the level of sound insulation. If you use cheap materials it only costs you a few dollars. If you choose the better materials, it can cost you several thousands of dollars to soundproof the whole room.

What are the benefits of soundproofing a room

Many people will agree that soundproofing a room offers considerable benefits because of the quiet and privacy it brings. Here are several common reasons why people apply soundproofing:

  • Soundproofing decreases the sound volume coming from outside to create a much more comfortable environment.
  • It allows creative works like making music or recording visual content without disturbing  people in nearby rooms or properties.
  • It provides a highly needed level of privacy for places such as banks and meeting rooms where confidential information is often discussed.

Cost To Soundproof A Room

The answer to the question: “How much does it cost to soundproof a room?” fluctuates widely based on the room itself.

The cost of soundproofing will vary from a few hundred bucks to thousands of dollars, depending also on the attributes of the material and whether you employ a contractor or do it yourself.

There are numerous soundproofing contractors available, but we will focus on the DIY direction in this post. It's important to note that these figures are just estimations, and you may save more after diligent market research before purchasing.

Manufacturers release updated goods on a daily basis, so keep an eye out for new technologies.

The total price of soundproofing a room depends on many factors. The main cost factors are as follows:

  • The used materials. 
  • The size of the room and the covers.

Many online products magnify absolute soundproofing. Therefore, it is very important to do your research.

Don't rely too much on word-of-mouth publicity because new materials are being developed every day; you may have a more effective system at a cheaper cost to make.

According to my thorough research, the price of soundproofing a room typically ranges between $1,000 and $2,500; the average cost for soundproofing a room is around 1,600 USD.

Before starting up a soundproofing project, it's crucial to know what is worrying you or maybe bothering you. The needs would be different when you have a drummer in the house or a studio for recording.

Various noises in the household can generally be classified into plumbing sounds, solid-borne sounds, impact sounds, and airborne sounds. It's crucial to find out which sound will be a bigger challenge, then you can figure a way to solve it.

Cost to Soundproof Specific Structures

Once the issue has been identified, it is just as necessary to get the right solution. Soundproofing vs sound-absorbing projects may involve soundproofing the whole space or only some areas in the building where you'll have to keep the noise out.

The two significant cost considerations are the size of the room and the level of sound insulation you need. Material and installation costs rely on the part of the space as follows:

Structure Cost
Windows $300 - $1,000/ window
Doors $1,000 - $5,000 depending on different types of door.
Floor $1,000 - $5,000 depending on the square footage of the room and material.
Walls and Ceiling $1,000 - $1,200 depending on the material and square footage used.
Surround Sound System Up to $10,000 depending on the system.

Cost Of Various Soundproofing Materials

Sound is like water; it penetrates even through the smallest gap. If the boisterous neighbors are directly above you, some of the vibrations must go through the walls as well.

If you're trying to keep the ceiling soundproof, you might as well take care of the whole room.

The greatest sound insulation is anything strong and sturdy, like bricks and mortar. They're not easy to use while renovating a room, so what else can you consider?

There are several advanced products online, but today I want to demonstrate how to do things as easily and cheaply as possible.

Determining the soundproofing specifications and estimating the budget before selecting an insulation material are what to keep in mind.

Cheap Soundproofing Options

You don't need a large budget to make a room more soundproof. Although these alternatives aren't as effective as some of the more costly options, they will significantly reduce unwanted noise.

All of these approaches cost less than $100 and help absorb sound:

  • To minimize echoes, incorporate comfortable furnishings such as beanbags or broad cushions.
  • To dampen vibrations tone, hang thick curtains over windows.
  • Place acoustic foam between or against the walls of the room.
  • To minimize incoming noise, put foam insulation tape in air pockets around doors and a plastic door sweep at the bottom.
  • Fill gaps in the floor, walls, and ceiling with caulk.
  • Use low-cost rugs on the floor.

Soundproofing Methods

Mass or bulk, damping, decoupling, and absorption are the four key methods to soundproof a room.

Adding Mass or Density soundproof

Adding Mass or Density

Adding mass or density to an object is one of the simplest ways to make it soundproof. The higher the density of the material, the tougher it is for the sound waves to penetrate it.

You may suppress noises in a variable frequency spectrum by combining different densities.


Decoupling is an easy and efficient soundproofing method since splitting the two faces of the wall such that the sound cannot easily move through it.

The two faces of the standard wall are joined together with wooden studs, making it possible for the sound to penetrate. Decoupling prevents the transmitting of sound and increases soundproofing efficiency.

Damping and Absorption

Damping and absorption are two linked soundproofing methods. absorption includes the use of rubbery soundproofing structures such as viscoelastic foam or neoprene rubber within walls to soundproof noise so that it is not completely transferred to the room.

Dampening includes the use of acoustically dead, extra-thick, and sturdy walls to block the noise

Installing Soundproofing Yourself

It is feasible to construct soundproofing material on your own. However, I highly suggest that you follow a certified and qualified specialist’s advice and assistance for the best performance.

There are several considerations to address before trying to complete the installation process on your own, so make sure to be prepared thoroughly.

Like every other house renovation project, soundproofing can be difficult to complete if you are not familiar with the method. Before doing some installation of your own, make sure you are confident in your skills.

Always obey the manufacturer's instructions to make sure you're using the right tools for the task. Failure to install will result in expensive repairs, so never attempt the installation if you are confused about it.

Installing Soundproofing Yourself

In this illustration, I'll show you how to add soundproofing foam to an internal wall step-by-step.

First - Start by calculating the area to be soundproofed and deciding on the desired results, whether it's to reduce noise from outside sources like neighbors and traffic or confine sound to a single area for a music room or home theatre.

Second - When you're using soundproofing foam sheets, you'll need special adhesive to adhere each part to your walls. To make sure you're using the right adhesive for your panels, always check the manufacturer's instructions.

Third - To ensure the room is clear of grease or debris, scrub the surface of the walls with rubbing alcohol or a specialized surface cleaner. Unclean walls hinder the installation process, potentially causing the soundproofing panels to collapse off the wall.

Fourth - Cut, trim, and measure each foam panel to fit the shape and scale of your room. A sharp retractable utility knife has the highest reliability and accuracy for tricky corners and edges and results in the best DIY outcome.

Fifth - Follow the manufacturer's instructions to apply the adhesive or repairing solutions. The adhesive should be evenly distributed around the back of the wall.

Sixth - Stick the foam panel boards to the inside walls' surfaces, leaving them in place for a few minutes before the adhesive becomes tacky.

Wait at least 24 hours before touching the boards to assure that the adhesive has completely hardened and the panels have been positioned correctly.


If you're doing the work yourself, remember to wear safety gloves and overalls, as well as eye protection and a dust shield.

New fiberglass isn't the only source of harmful dust. There could be surfaces polluted with rat droppings and old construction products tainted with asbestos if you touch old walls and ceilings.

Ensure the ladders are safely placed and in good working order.


If you have disruptive neighbors, live along a busy highway, or have a teenage son who wants to learn to play the drums, it may be worth getting one or more rooms soundproofed. It will not only benefit you, but it will also benefit your neighbors.

The soundproof project would be dictated by the criteria and the amount of money you are able to pay. When you are renting a house from a landlord, you would not want to overspend.
