How To Soundproof Bedroom

Do you want to enjoy a peaceful sleep without being disturbed by the noise outside? Or do you want to create a quiet space for your work or hobbies? If you answered yes to any of these questions, then you might be interested in learning how to soundproof your bedroom.

Soundproofing is the process of reducing or blocking the unwanted sound from entering or leaving a room.

The solution to soundproofing your bedroom is to use a combination of materials and techniques that can absorb, reflect, or dampen the sound waves.

Some of the materials you can use are acoustic foam panels, soundproof curtains, carpets, and blankets. Some of the techniques you can apply are sealing the gaps, adding mass to the walls, and creating air gaps. These methods will help you reduce the noise level and improve the acoustics of your room.

In this article, you will find out more about the benefits of soundproofing your bedroom, the steps you need to follow, and the best products you can buy. You will also learn some tips and tricks to make your soundproofing project easier and cheaper.

By following this guide, you will be able to create a comfortable and quiet environment for yourself and your loved ones.

Understand How Sound Travels and Is Blocked

To soundproof a room effectively, it helps to first understand some basics of how sound moves through space and interacts with different materials.

How Sound Travels

  • Sound consists of vibrations that cause fluctuations in air pressure. These fluctuations transmit sound waves outward in all directions from the source.
  • Sound can travel through most materials, including air, water, wood, metal, glass, and more. However, each material conducts, absorbs, or reflects sound waves differently.
  • The frequency (pitch) of a sound impacts how easily it is blocked. Lower frequency sounds are harder to absorb and contain.

How Sound Enters a Bedroom

Sound can find its way into a bedroom through various openings, gaps, vents, and shared surfaces:

  • Doors and windows – Even small gaps allow high frequency sounds to transmit. Hollow doors poorly block noise.
  • Electrical outlets/switches – Openings in wall allow sound entry from other rooms.
  • Vents and ducts – Noise can travel through HVAC systems.
  • Baseboards and trim – Gaps along the wall/floor junction are vulnerabilities.
  • Shared walls – Noise like voices and music can bleed through from adjacent rooms.
  • Ceilings and floors – Impact noise like footsteps transfer through.

DIY Soundproofing Strategies and Solutions

Fortunately, there are many cost-effective ways to reduce noise infiltration in the bedroom using common household materials and supplies. Here are some of the most effective sound dampening and noise blocking techniques:

Seal Gaps and Openings

Applying caulk, weatherstripping, sweeps, or acoustic sealant around doors, windows, outlets, vents, baseboards, and even wall cracks significantly reduces openings where sound can enter.

  • Door sweeps – Install on bottom of doors to close gap between door and floor. Sweeps seal tightly when door is closed to block noise.
  • Perimeter door seals – Adhesive rubber seals around full door perimeter seals gaps when shut.
  • Outlet sealers – Inserts with acoustic insulation reduce sound traveling through outlets.
  • Caulk and sealant – Fills cracks and openings with a flexible waterproof seal. Acoustical caulk adheres surfaces to block sound.
  • Weatherstripping – Tape strips seal air gaps around window and door frames when closed.

Install Thicker Doors

Solid wood or metal doors with special acoustic seals provide far more noise blocking than standard hollow core doors. Consider upgrading bedroom doors to one of the following:

  • Solid wood doors – The dense structure blocks considerably more sound than lightweight hollow or paneled doors.
  • Solid core doors – Interior doors filled with wood blocks, particleboard, or mineral wool offer good sound insulation.
  • Soundproof door systems – Specialty acoustical doors and seals specifically engineered to reduce noise infiltration. They carry a Sound Transmission Class (STC) rating – higher is better.

Add Insulation

Adding fiberglass, rockwool, foam, or other insulation intelligently places excess density in walls, ceilings, and floors that dampens vibrations and absorbs noise. Strategically placed insulation can make a big difference in soundproofing your space.

  • Rockwool insulation – This dense stone wool insulation material resists sound conduction very effectively.
  • Blown-in insulation – Loose material pumped into walls adds mass. Cellulose and fiberglass work well.
  • Soundproof drywall – Uses viscoelastic glue between layers to dampen vibrations.
  • Resilient channels – Metal channels used to hang drywall help isolate it from structural vibrations.

Rearrange Furniture

Strategically placing furniture like beds, couches, armoires, and bookshelves against walls that border noisy areas can help block sound transfer through the wall. This uses furniture’s mass to essentially create a thicker, more soundproof wall.

  • Position bed against shared wall with living room, rather than against quieter exterior wall.
  • Place wide bookshelves lined with books against shared walls to absorb noise energy.
  • Floating nightstands positioned against walls perform better than standalone furniture.

Hang Sound Absorbing Materials

Decorative sound dampening materials like curtains, tapestries, quilts, and wall hangings work by absorbing noise energy instead of reflecting it. This cuts down on echoes and reverberation within the bedroom that amplify sound.

  • Soundproof curtains – With thick, noise-blocking material layered inside. Close tightly over windows.
  • Acoustic panels – Wall tiles made of sound absorbing foam or acoustic felt to reduce reverberation.
  • Quilts and blankets – Tapestry, quilts, and thick blankets hung on walls absorb and diffuse sound.

Upgrade Windows

Poorly sealed, hollow windows allow noise to easily penetrate from outside. High performance acoustic windows block considerably more exterior sound.

  • Acoustic windows – Multi-pane layers of glass separated by air/gas pockets block outside noise.
  • Sealing windows – Ensure window frames are properly caulked and sealed to eliminate gaps around perimeters.

Add Carpeting and Rugs

Thick carpeting, carpet pads, and area rugs help absorb both airborne and impact noises like footsteps. The soft, dense pile of carpet prevents sound transmission along the floor.

  • Wall-to-wall carpet – Offers full floor coverage for sound absorption rather than hardwood or tiles.
  • Carpet underlay – An intermediate padded layer under carpet improves sound dampening.
  • Area rugs – Large rugs add mass and softness to hard flooring in bedrooms.

Use Sound Dampening Materials

Specialized construction materials like Green Glue, mass loaded vinyl, and acoustical drywall can significantly reduce noise when installed properly throughout walls, floors, and ceilings. This option requires more expertise but delivers excellent sound blocking for bedrooms.

Additional Soundproofing Tips for Bedrooms

Along with physical upgrades to the bedroom’s structure, there are a few additional tactics that can help reduce noise:

  • Use a white noise machine to mask unwanted sounds with steady, unobtrusive background noise.
  • Try earplugs or sleep headphones to physically block noise from entering the ear canal.
  • Ask housemates to avoid loud music, TVs, and conversations late at night near your room.
  • Run a fan or air purifier to generate ambient white noise.
  • Switch off any unnecessary electronics that produce audible hums or buzzes.


Transforming your bedroom into a peaceful, quiet sanctuary conducive to deep sleep is very achievable using DIY soundproofing materials and a bit of creativity.

This guide covered a wide array of noise blocking strategies, including sealing gaps, adding sound-absorbing surfaces, using furniture and layouts strategically, upgrading doors and windows, installing insulation, thick carpeting, and more.

With an understanding of how sound travels and enters a room, you can target the most problematic areas and sound frequencies. Do-it-yourself sound dampening can make a dramatic difference in reducing unwanted noise without major renovation or construction.

Prioritizing a quiet, tranquil sleep environment provides physical and mental health benefits that can improve your sleep quality, mental sharpness, productivity and overall well-being. So explore these soundproofing techniques for finally getting the peaceful slumber you deserve each night!
