How To Soundproof Room From Fireworks

The loud pops and booms of fireworks can be fun to watch, but all that noise penetrating into your home can be annoying and disruptive. Fortunately, there are ways to soundproof a room so the loud sounds of fireworks don’t disturb you, allowing you to relax and sleep peacefully even when your neighbors are putting on colorful pyrotechnic displays.

Assess Noise Levels

The first step is to assess just how loud the fireworks noise is in the room you want to soundproof. Go in the room, close the doors and windows, and have someone outside set off some fireworks while you use a decibel meter app on your smartphone to measure the noise level.

Make notes of the highest decibel readings. If the noise level exceeds 45 dB in the room, then soundproofing efforts will be worthwhile. The louder the noise, the more aggressive you’ll need to be with soundproofing techniques.

Block Noise Through Windows

One of the main ways noise enters a room is through windows. Even closed windows will allow some noise transmission. Here are some great options to block noise through windows:

Soundproof Curtains

Hanging heavy, insulating soundproof curtains over windows is an effective way to dampen noise. Curtains made from dense materials like velvet, cotton, wool, or quilted fabrics work best. For maximum noise blocking, make sure curtains are hung as close to windows as possible, are wide enough to overlap window frames, and extend all the way to the floor.

Acoustic Film

Specialized acoustic window films are available that stick directly onto window glass to reduce noise transmission. These films come in various thicknesses to dampen different sound frequency ranges. They can reduce noise coming through windows by several decibels.

Indoor Window Inserts

Window plugs made of acrylic or plexiglass can be inserted into window frames, creating an extra air gap between window layers that blocks more noise. Heavy rubber or foam window seals can also be installed around window edges to seal gaps and prevent noise infiltration.

Add Insulation

Adding insulation is one of the most effective ways to soundproof walls and ceilings. The thicker and denser the insulation, the better the noise reduction. Recommended insulation materials include:

Mineral Wool

Safe and non-flammable mineral wool insulation works incredibly well for soundproofing. It’s available in batts or boards to fit between wall studs or ceiling joists. Use insulation rated at R-13 or higher for optimal noise blocking.


Loose shredded cellulose made from recycled materials can be blown into wall and ceiling cavities. Having a professional install dense cellulose insulation improves noise reduction.

Soundproof Drywall

Using special soundproofing drywall containing viscoelastic polymers that dampen noise can make a big difference. It’s thicker than regular drywall and requires careful installation using acoustical sealant between sheets to create an effective sound barrier.

Isolate Noise Flanking

Flanking occurs when noise travels through the weak points in a structure and enters a room through paths aside from the walls, like ductwork or under the door. Here are some ways to isolate flanking:

Seal Outlets/Switches

Seal around electrical outlets and switches on walls with acoustical caulk. This keeps noise from leaking through small openings. Outlet plugs that expand to seal outlets are also available.

Weatherstrip Doors

Install thick weatherstripping around all doors and door frames to block noise escaping under or around doorways. Threshold seals for exterior doors help too. Keep doors closed and use solid core doors for better noise reduction.

Seal Ducts

HVAC ducts traveling through walls and ceilings can transmit noise. Seal ducts with acoustical mastic where they meet wall plates and vents. Lined ducts also dampen noise.

Add Mass and Layers

Adding mass and layers is key for blocking noise. The more mass a wall has, the more difficult it is for soundwaves to vibrate through. Some great ways to build up layers:

Double Drywall

Staggering studs and using two layers of drywall with Green Glue noiseproofing compound between them creates a dense noise barrier. The staggered studs prevent direct contact between drywall sheets.

Safe N Sound

Two layers of special Safe N Sound drywall, which has a viscoelastic polymer core for damping sound, is extremely effective. Stagger the drywall with Green Glue applied between layers.

Staggered Stud Walls

Use double or staggered stud walls with two rows of studs and insulation between them. This breaks up sound vibration pathways and improves noise reduction.

Green Glue

Apply Green Glue noiseproofing sealant between layers of drywall or onto studs before installing drywall. The viscoelastic properties of Green Glue turn noise energy into low frequency heat energy.

Sound Isolation Clips/Channel

Installing sound isolation clips or channels creates an air gap between drywall and studs that prevents noise transfer. These clips decouple the drywall from framing. Popular options include:

Resilient Channels

Thin metal resilient channels are installed horizontally across studs before drywall. Drywall is then screwed into channels instead of studs. This breaks the noise vibration path from wall surfaces.

Hat Channels

These furring channels look like inverted top hats. They are installed vertically to studs with an air space maintained behind drywall panels. Great for ceilings too.


Z-shape channels clip to studs and provide isolation for two layers of drywall. Drywall panels are installed on either side of the Z-channels. The configuration works great for soundproofing.

Absorb Sound Energy

Using sound-absorbent materials on walls and ceilings soaks up noise energy instead of reflecting it back into a room. This reduces reverberation that amplifies noise. Effective options include:

Acoustic Panels

Decorative fabric covered acoustic panels adhere to walls and ceilings to absorb mid-high frequency sounds. Place strategically around noise sources. Panels come in stylish shapes like triangles, waves, hexagons etc.

Acoustic Insulation

Insulation materials rated for acoustical use like Roxul Safe N Sound work great installed between wall studs or ceiling joists. The density and fibers absorb noise rather than reflecting it.

Acoustic Drywall

In addition to providing mass, specialized acoustic drywall dampens noise through absorbent properties. Brands like QuietRock work as both a sound barrier and absorber.

Additional Tips

  • Install a quality solid core or soundproof door with full perimeter seals
  • Seal air leaks throughout room with acoustical caulk
  • Add weatherstripping to electrical outlets/switches
  • Make sure flooring is completely sealed, gaps allow noise infiltration
  • Add thick area rugs over hard flooring for additional sound dampening
  • Keep room clutter/furniture minimal for better sound absorption

With some DIY efforts using these noise reducing techniques, you can effectively soundproof a room from loud fireworks noise. Your space will be much more peaceful!

Paying attention to details like sealing cracks, using the best materials, and layering soundproofing elements results in optimal noise blocking so you hear less of the explosive celebrations.
