How much does it cost to soundproof a room?

Soundproofing is the process of using insulative material to control and isolate sound from an undesirable source; for example, a busy road or noisy neighbors. In the United States, the sound insulation of buildings is measured in terms of sound transmission class (STC). While a poorly-made partition wall, through which you can hear everything happening on the other side, will have an STC score in the 20s, a luxury hotel room may have a score in the 60s. Most residential buildings have a score between 30 and 45.

The cost of soundproofing an average room in the U.S. can range from $1,000 to $2,500, including labor, materials, and tools. The final price will depend on the location, quality of the materials, and the size of the room.

Pros and cons

Soundproofing can greatly improve the quality of your life with as little disruption as possible to you and your property. Soundproofing has also been found to be very useful in industries where high levels of noise are not only irritating, but also harmful to health. Continued high noise can disrupt an employee’s focus at work, as well as cause long-term hearing disabilities.

A major disadvantage of soundproofing is the cost and inconvenience of adding soundproofing to existing construction. Soundproofing may also prevent people from hearing the sounds they should be able to hear, for example, an emergency siren.

Reasons to soundproof a room

Noise is an undesirable, but inevitable, part of everyday life. Constant noise, even unintentional, can keep a person on edge all the time and raise stress levels.

  • People commonly apply soundproofing for the following reasons:
  • To reduce the disturbance caused by noisy neighbors or traffic.
  • To enhance and contain the sound in a home theater.
  • To avoid disturbing other people at home while playing a musical instrument.
  • For privacy.

Soundproofing vs acoustic treatment

While soundproofing is used to control and isolate sound from an undesirable source, acoustic treatments are used to improve and direct sound to a particular area. Acoustic treatments are commonly done in areas like home theaters where the direction and flow of sound can make a huge difference.

Things to do before soundproofing

Identify the source of the problem sound. If you want to block out the sounds of people walking on the top floor, consider installing carpet instead of noisier floor materials like wood or tiles. If someone in the family plays a musical instrument, you may explore the idea of setting up practice in the basement instead of the main living floor. Cutting off sound at the source is often easier, cheaper, and more effective than other sound-reducing methods.

Find out how the noise is being transmitted into the room. Noise can be airborne noise or flanking noise. Airborne noise travels directly through the air. Examples: the sound of traffic or people talking. Flanking noise transmits between spaces indirectly, traveling over or around spaces, instead of through them. Flanking noise can travel between spaces even if the separating element provides good sound insulation. Noise traveling from one room to the other by some path other than through the wall is flanking noise.

Identifying the reflection points in your room is another way to reduce noise and control sound. Breaking up the reflection points with thoughtfully placed furniture that can absorb the sound instead of reflecting it can help control the acoustic energy in the room.

Soundproofing options

Soundproofing can be done post-construction as well as during new construction using a variety of different techniques.

Already built room

To soundproof an already built room, you may choose to add a door sweep to reduce external noises (as well as keep insects and bugs at bay), install acoustic wedge panels ($1.60-$4.60 per sq.ft.), blow insulation into the existing wall by drilling a hole, add mass loaded vinyl 1 ($100-$200 for a 40 sq.ft. roll) between the two layers of drywall, or build a soundproof wall over the existing wall.

New construction

If you’re building a new soundproof wall, you may choose to implement any one or a combination of the following options:

  • Adding 2 ½” metal wall studs.
  • Adding a second layer of drywall 2 to one or both sides of an insulated wall.
  • Building a wall by mounting 3 the drywall on resilient channels or sound clips across the wall.
  • Using staggered wall studs along with two thicknesses of fiberglass 4 insulation.
  • Removing fireblocking (only if allowed by local building codes).
  • Adding mass loaded vinyl ($100-$200 for a 40 sf.ft. roll).
  • Adding acoustical caulk 5 ($15 per 50 linear ft.) around all openings where air may pass through.

Soundproofing floors and ceilings

If you are looking to soundproof your room against impact noise (the sound of footsteps or objects falling against the floor), a heavy carpet and rug pad 6 offer a quick and easy fix. If it is new construction, you can install resilient underlayment 7, vinyl barrier (starting from $1.50 per sq.ft.), and soundproof insulation between the floor joists and sound clips below the joists for best results. Carpet underlayment, which consists of a resilient acoustic foam layer with a vinyl barrier on one side, and costs between $3.45-$5.15 per sq.ft., offers good results for carpeted floors.

To block sound waves traveling through the ceiling, you can add insulation between ceiling joists, including on top of any recessed ceiling lights, add resilient sound clips ($6 each) on ceiling joists, add a second layer of drywall using green glue, or fill the space between seams 8 and the perimeter using acoustic caulk ($15 per tube).

Regular vs soundproof drywall

Most regular drywall ($10 per sheet) has a solid core made of a material like gypsum, between layers of paper, which makes the wall vibrate in accordance with sound and allow it to pass through. In the case of soundproof drywall ($54 per sheet), the gypsum is replaced by a layer of gypsum, ceramics, and viscoelastics, which together create a more effective barrier against noise. Soundproof drywall can be very effective in situations where it is not possible to reframe or use other structural methods for reducing noise. If you are on a budget, you can limit soundproof drywall only to rooms where soundproofing is a priority, for example in bedrooms.

Labor

Soundproofing can be achieved using different techniques, such as adding mass, dampening, decoupling, and/or filling air gaps.

A wall has to actually vibrate to allow sound to pass through it. Since a heavier wall is more difficult to move than a lighter wall, adding mass or making the walls as heavy as possible can help reduce noise.

Dampening and absorbing are two related soundproofing techniques. While absorbing involves using rubbery soundproofing materials such as neoprene rubber or viscoelastic foam between walls to “absorb” incoming noise so that it does not fully transmit into a room, dampening involves using a solid, extra-thick, acoustically dead wall that does not vibrate.

Decoupling is a simple and effective soundproofing technique that involves mechanically separating the two sides of a wall so that sound cannot pass through it easily. The two sides of a traditional wall are coupled by wood studs, which makes it easy for sound to pass from one side to the other. When you use a resilient decoupling mount, it hinders the transmission of sound and improves the soundproofing performance.

While you may be able to do smaller soundproofing projects such as hanging curtains and tapestries, or switching out normal paint with soundproofing paint by yourself, you will need to hire a general contractor ($15-$60 per hour) or a handyman ($12-$45 per hour) for larger projects that involve replacing windows or installing wall panels.

Enhancement and improvement costs

Weatherstripping

You can soundproof your home for much less by installing a door sweep under the doors and by using weather stripping foam tape around all sides of the door frame. It will help create a better seal, reduce sound leaks, and keep critters away. The average cost of weatherstripping a home in the U.S. is around $168.

New windows

You can soundproof windows in different ways: by adding heavy curtains, by installing a soundproof window in addition to the existing window, or by replacing the existing windows with double pane glass ($350-$900). Adding a soundproof window ($350-$800) to the existing window can offer sound reduction of up to 95%.

Chimney soundproofing

An open chimney can be a source of unwelcome noise. You can soundproof a chimney in three ways: by using a chimney balloon ($45-$55), by adding a flueblocker ($35-$55), or by installing a chimney cap ($50-$2,000). The first two methods are easy and you may be able to do it yourself. If you do not have experience working on rooftops, it is recommended that you hire a professional to fit a chimney cone.

Additional considerations and costs

  • You can soundproof a room on your own as long as you are willing to invest a little time and effort. However, the success of your DIY project depends to a great extent on your knowledge and the type of noise you are facing.
  • Soundproofing your home doesn’t always have to be difficult or expensive. Easy and cheap soundproofing strategies, such as installing a commercial-grade door sweep with a thick rubber strip that will seal against the threshold, can also help keep out a lot of noise. Putting heavy curtains over the doors, adding shag rugs to the floor, installing thick rug pads 6 under the carpet in high-density areas, arranging bookcases against walls, and adding window inserts over existing windows are other, more budget-friendly options.
  • Be on the lookout for air quality problems when soundproofing a room. When you make a room airtight, it will reduce noise, but it will also make the room more stuffy, unless you have a forced air heating/cooling system. Improper ventilation can cause health problems for people with asthma and other respiratory issues.

FAQ

  • What is the cheapest way to soundproof a room?

One of the cheapest ways to soundproof a room is by hanging heavy curtains and tapestries on the doors and walls. The thicker the material, the better it will be at absorbing sound. Adding thick rugs and a rug pad below the carpet, installing a door sweep, and placing massive furniture against walls are other inexpensive ways to soundproof a room.

  • How do you soundproof an existing wall?

There are many ways to soundproof an existing wall. However, the most popular and affordable way is to add mass and seal gaps where sound may leak through. You can also add insulation into an existing wall using specialized equipment.

  • How do you soundproof a room?

To soundproof a room, you should first identify the source of sound. Find out how the noise is entering the room, and then choose the appropriate soundproofing materials for efficient soundproofing.

  • What is the best material for soundproofing?

Air is considered to be the best material for soundproofing. The traditional building method called double studding, which involves two walls mechanically separated by a zone of dead air, can help block the transmission of sound.

  • How much does it cost to soundproof a room?

On an average, it costs around $1,000-$2,500 to soundproof a room in the U.S. This includes the cost of labor, materials, and tools.

  • How can I make my room soundproof from outside noise?

External noise often enters a room through big gaps around the door. You can prevent this by installing a commercial-grade door sweep that will seal against the threshold and block outside noise, as well as bugs and insects. Heavy blackout curtains that seal against the door will also help soundproof a room against external noise.

  • Can you soundproof existing walls?

Yes, you can soundproof existing walls by adding mass, sealing gaps which allow sound to leak through, adding insulation into the existing wall, or by building a second wall over the existing one using soundproofing materials.

  • How can I reduce noise between rooms?

You can reduce noise between rooms by using different soundproofing techniques, such as absorbing, dampening, and decoupling. You can also stop noise from traveling between rooms using different soundproofing materials, such as draft stoppers, heavy carpets, thick curtains, acoustic panels, and wall hangings.

  • Are egg cartons soundproofing?

While egg cartons are inexpensive and can reduce echoes and certain frequencies, they are not very effective when it comes to reducing sound. However, they are very similar in size, shape and appearance to the soundproofing acoustic foam used in music studios, which may have given rise to the myth that you can use them for soundproofing.
