A neighbour’s TV through the wall. Footsteps overhead at midnight. Traffic that never stops. Noise is often the hardest part of apartment living.
You can make an apartment noticeably quieter without renovation or risking your deposit. First find where the noise gets in.
See our Apartment Guides.
TL;DR
- Diagnose first. Do a listening walk at night and find the loudest path — door, window, shared wall, ceiling, or floor.
- Seal the gaps. A door sweep and weatherstripping are the cheapest, highest-return fixes.
- Add mass and softness. Heavy curtains, thick rugs with dense pads, and furniture against a shared wall help.
- Absorb echo inside. Soft furnishings and acoustic panels cut echo.
- Use white noise as a fallback. It masks low-level noise; it does not block it.
- Get written permission first for anything permanent.
- Be realistic. You cannot fully soundproof a rental. The goal is noticeably quieter, not silent.
Find Where the Noise Gets In
Before you spend anything, do a listening walk. It is free and takes 15 minutes.
Wait until the building is at its noisiest, then stand quietly by the front door, windows, shared wall, ceiling, and outlets. Note what you hear. A gap you can feel is a leak; a sound from the whole wall is travelling through the building. Fix the loudest path in the room where you sleep or work first.
The Two Types of Apartment Noise
| Type | What it is | Examples | What helps most |
|---|---|---|---|
| Airborne noise | Sound travelling through air | Voices, TV, music, traffic | Mass, density, sealing gaps |
| Impact noise | Vibration through the structure | Footsteps overhead, dropped objects | Cushioning, decoupling |
Airborne noise slips through walls, windows, doors, and gaps. The fix is mass — heavier, denser materials — plus sealing openings.
Impact noise is created by physical contact and travels through the floor, ceiling, and walls. That is why footsteps from upstairs sound so loud. Stopping it needs cushioning and decoupling, which is much harder for a renter.
Sound absorption: soft materials trap sound and stop it reflecting off hard surfaces. It reduces echo, but does not block neighbour noise.
1. Seal the Gaps Around Your Door
Sealing small gaps offers the highest return for most renters. Even a small gap under a door lets hallway voices straight in.
Add a door sweep — a strip that hangs from the bottom of the door and touches the floor. Removable sweeps cost little and take minutes to fit.
Add weatherstripping — foam or rubber tape around the door frame, creating a tighter seal when the door closes.
Together they often cost $15 to $40 and take about 15 minutes. Where light gets in, sound gets in.
If your front door is fire-rated, do not fit permanent gaskets without written landlord permission.
2. Fix Noisy Windows
Windows are usually the weak point for traffic and sirens, especially older single-pane glass. You cannot replace the glass as a renter, but you can reduce what gets through.
- Lock the sash. An unlocked sash leaves a gap. Locking it pulls the two parts together. It is free — check it first.
- Seal what you are allowed to seal. Removable window seal tape can help around a draughty frame, if your lease allows it. No permanent caulk without landlord permission.
- Hang heavy curtains. Blackout or velvet curtains, hung ceiling to floor, absorb some sound. Thin curtains do almost nothing.
- Consider window inserts, lease permitting. A press-in insert creates a second layer with an air gap, cutting traffic noise. Check first and keep approval in writing.
Heavy curtains can also help with heat — see how to cool down an apartment without AC.
3. Seal Outlets, Pipes, and Small Leaks
Once the big gaps are closed, the small ones matter. Voices slip in around outlets and wall edges, and through openings for pipes and ducts.
Outlets on a shared wall. An outlet box is a hole in the wall. Acoustic putty pads behind the switch plate can reduce leakage. Turn the power off at the breaker first.
Pipes and wall edges. Where pipes pass through a wall or floor, there is often a gap. Acoustic caulk is designed for this, but it needs landlord permission.
Vents and ducts. A shared vent can carry voices between rooms. Do not block a vent — it is there for airflow and safety. For airflow, see how to vent air in an apartment.
4. Soundproof a Shared Wall
Structural fixes — extra insulation, a second drywall layer, resilient clips — work well, but they are renovation work and need written landlord permission, which is rarely given.
What can you do without touching the structure?
- Move furniture off the shared wall. A bed with its headboard against it puts your ears against the noise path. Move it to an inside wall.
- Put a heavy bookcase against it. A tall, full bookcase adds mass. Fill it with books — paper is dense.
- Hang mass loaded vinyl, if your lease allows it. Mass loaded vinyl (MLV) is a thin, heavy sheet, hung like a tapestry. It adds real mass without permanent adhesion.
- Use acoustic panels for echo, not blocking. Panels absorb sound and cut echo, but they will not block your neighbour’s TV or bass.
- Try heavy curtains or tapestries. They add absorption and a little mass, and are cheap and removable.
5. Ceilings and Footsteps From Above
Footsteps from above are the hardest problem for a renter, because the fix is usually on the other side of the ceiling — in the flat upstairs.
From below, your options are limited. Heavy fabric and ceiling panels can reduce echo, but neither will stop impact noise travelling through the structure.
Talk to the neighbour upstairs first, politely — they may not know how loud footsteps sound below. Ask your landlord in writing about carpet or underlayment upstairs; many leases already require hard floors to be partly covered. Use rugs and white noise or earplugs at night.
Do not screw, glue, or attach anything permanent to the ceiling without written permission.
6. Floors: Thick Rugs and Dense Pads
If you have hard floors, rugs are one of the simplest and most effective steps — for the people below you, and for echo in your own flat.
Use thick rugs in high-traffic areas. A thick rug absorbs impact, softens footsteps, and stops sound bouncing off a hard floor.
Add a dense rug pad underneath. A dense felt or rubber pad cushions impact before it travels through the floor, and stops the rug slipping. Look for a pad at least 6 to 8 mm thick. Cheap, thin pads do little.
Cover as much as you can. Covering most of the walking path helps a lot. If choosing between a rug and acoustic panels, start with the rug.
Soft furnishings also make a small room feel bigger. See how to make a small apartment look bigger.
7. Soften Echo and Use White Noise
A bare apartment with hard floors and empty walls will sound noisy. Every sound bounces, and echo makes normal noise feel louder.
Add soft materials where you spend the most time: heavy curtains, an upholstered sofa, cushions, a full bookcase, and a rug with a dense pad. Clap once in the room — if it rings, add more soft material.
Keep soft furnishings clean and aired. See how to get rid of smell in an apartment.
White noise and earplugs are a low-cost fallback. A white noise machine produces a steady sound that covers up irregular sounds like voices, traffic, or footsteps. Place it between you and the noise source, and keep the volume low enough to hear an alarm.
Earplugs are the cheapest option for sleep. Foam earplugs are cheap and disposable; silicone earplugs cost more but suit side sleepers. Use masking while you fix the leaks, not as a replacement.
What Needs Landlord Written Permission
Anything structural, permanent, or safety-related needs written permission first: caulking, extra insulation or drywall, window inserts, attaching MLV or panels with screws or glue, work on a fire-rated door, and floating floors or a ceiling rebuild.
What usually does not need permission: a removable door sweep, peel-off weatherstripping, heavy curtains, rugs, freestanding bookcases, panels on removable hooks, and a white noise machine.
When in doubt, ask in writing and keep the reply. If the landlord says no, do not do it anyway.
A separate bedroom with a door is quieter than an open-plan studio. See studio apartment vs 1 bedroom.
Realistic Expectations
You cannot fully soundproof a rental, because the parts that block sound best — the walls, floors, and ceilings — belong to the building. Many older buildings fall well short of modern sound targets, and no removable product can fix a thin structure.
A realistic goal is a noticeably quieter apartment. Seal the door and windows, add heavy curtains and rugs, move furniture off the shared wall, and add soft furnishings — voices become murmurs, traffic becomes background, and sleep gets easier.
If the noise is extreme, document dates, times, and what you heard, and raise it with your landlord in writing. Structural noise is a building issue, not a renter DIY project.
FAQ
Can you fully soundproof a rental apartment?
No, not fully. True soundproofing needs mass, decoupling, and sealing in the walls, floors, and ceilings, which belong to the building. You can seal gaps, add mass, and absorb echo — noticeably quieter, but not silent.
What is the cheapest way to soundproof an apartment?
Start free: do a listening walk, lock your windows, and move your bed away from the shared wall. Then buy a door sweep and weatherstripping, usually $15 to $40, and thick rugs with dense pads.
What is best for noisy neighbours through a shared wall?
Seal the gaps first, then add mass with a full bookcase or, if your lease allows it, mass loaded vinyl hung like a tapestry. Move your bed to an inside wall. Acoustic panels help with echo, but they do not block neighbour noise.
How do I stop footsteps from the apartment above?
From below, you cannot stop impact noise travelling through the structure. Reduce echo with rugs, talk politely to the neighbour upstairs, and ask your landlord in writing about carpet or underlayment upstairs. White noise or earplugs can help while you sleep.
Do acoustic panels block neighbour noise?
No. Acoustic panels absorb sound inside your room and reduce echo, but they do not add enough mass to block sound through a wall or ceiling. They make your room calmer, but they are not a sound-blocking fix.
Final Thoughts
Find the loudest path, seal the gaps, add mass and softness, and ask your landlord in writing for anything structural.
You do not need a renovation to feel the difference. A door sweep, heavy curtains, and a thick rug with a dense pad will do more than a wall full of foam panels bought in the wrong order.
Start with the listening walk tonight. Your apartment will not become silent, but it can become quieter.
