How to Soundproof a Bedroom

Windows are one of the most common weak points for noise entering a bedroom, especially from traffic, neighbors, or environmental sounds. Even thick walls won’t perform well if sound can pass through glass or gaps around the frame. Start by sealing cracks and gaps around the window frame with acoustic caulk. Next, you can turn any windows into a soundproof window using Fantastic Frame™ window inserts.

Some people also try solutions like Quiet Quilt Acoustic Blanket or mass loaded vinyl sheets as curtains, but these approaches typically provide less reduction than a properly sealed insert. If cost is a main concern of yours, check out our article on the cost of soundproofing a window.

Bedroom doors act as large openings in a wall and often leak sound through gaps around the perimeter or under the door.

There are a lot of approaches to soundproofing a door, but results improve significantly when starting with a solid core door instead of a hollow one.

Once the door itself is addressed, sealing is critical. A Sound Lock™ door soundproofing kit helps close perimeter gaps that allow sound to leak.

Some people try using weatherstripping or door sweeps to soundproof a door, but these methods usually deliver limited improvement compared to full perimeter sealing.

After windows and doors, walls are often the largest remaining sound path — especially in apartments or homes with shared walls. To understand the fundamentals, start with how to soundproof a wall:

• Best solution: Build a decoupled wall using RSIC clips. These sound isolation clips for drywall reduce vibration transfer through framing.
• Good solution: Add a second layer of drywall with Green Glue Noiseproofing Compound. For guidance, see mass loaded vinyl vs Green Glue.

No matter the approach, seal outlets, seams, and edges with acoustical sealant to prevent sound leakage.

Floors commonly transmit impact noise such as footsteps and dropped objects, especially in multi-story homes. Install acoustic carpet underlay under the finished floor to reduce both impact and airborne noise through the floor assembly. Learn more about how to soundproof a floor here.

Ceilings transmit both airborne noise and impact noise from above. For structural isolation, use RSIC-1 clips and 25 gauge hat channel for the best results. Install 5/8" drywall with a 1/4" gap around the edges to be sealed with acoustical sealant. An additional drywall layer can help reduce airborne noise further.
