Short answer
Seal the gaps first — sound travels through air, so a gap under the door matters more than wall thickness. Add soft furnishings to absorb reflections, heavy curtains for window noise, and use masking noise for what remains. Total silence is rarely achievable without construction work.
Noise reduction has two mechanisms that get confused: blocking sound coming in, which needs mass and airtightness, and absorbing sound reflecting inside the room, which needs soft surfaces. A bedroom usually needs some of both, plus masking for what neither can remove.
What you'll need
- Draught excluder strip
- Heavy lined curtains
- Rugs and soft furnishings
- Earplugs (optional)
- White noise source or fan (optional)
Step by step
- Seal the gaps around the door.Sound travels through air very efficiently. A gap under a door undoes any amount of wall insulation.
- Replace a hollow internal door with a solid one if noise from inside the house is the problem.A hollow-core door blocks very little and is often the largest weak point.
- Fit heavy lined curtains, floor length and wider than the window.Windows are the weakest point in an external wall for sound. Mass and full coverage both help.
- Add soft surfaces — rugs, upholstered furniture, a full wardrobe against a party wall.They absorb reflections and make the room measurably quieter, though they do not block sound from outside.
- Check for gaps around pipes, vents and sockets.Any hole through a wall is a sound path. Sealing them is cheap and effective.
- Use masking noise for what remains.A fan or white noise raises the noise floor so intermittent sounds are less noticeable. Often more practical than construction.
- Consider earplugs.Unglamorous and the most effective single measure available for most people, at almost no cost.
- Be realistic about what is achievable.Meaningful reduction is realistic. Total isolation needs construction most homes cannot justify.
Tips
- Foam panels absorb reflections inside a room and do essentially nothing to block sound coming in from elsewhere. That distinction is widely misunderstood.
- Moving the bed away from a party wall makes more difference than most treatments applied to the wall.
- If the noise is from neighbours, talking to them is often more effective and far cheaper than any building work.
Common mistakes
- Adding mass to a wall while leaving a gap under the door — Sound finds the weakest path. Sealing gaps is usually higher value than insulating.
- Using foam panels to block external noise — They absorb reflections inside the room and do almost nothing to sound coming through a wall.
- Expecting silence — Meaningful reduction is realistic; total isolation requires construction most homes cannot justify.
Questions people ask
What is the cheapest way to make a bedroom quieter?
Sealing the gap under and around the door, heavy curtains, and earplugs. All three are inexpensive and address real transmission paths rather than the idea of one.
Do soundproofing foam panels work?
For echo inside a room, yes. For blocking noise from outside or next door, essentially no — that needs mass and airtightness, which thin foam cannot provide.
