The cheapest way to quiet an apartment is to seal the gaps and add soft, heavy materials: thick rugs, lined curtains, a door sweep and weatherstripping. For loud neighbors or traffic you will need mass, meaning denser walls, a solid door and sealed windows, and that usually needs the landlord's consent or a renovation. This guide shows how to find where the noise comes in, what to fix first, what is worth the money, and how to check an apartment's acoustics before you sign or buy.
TL;DR
- Find the path first. Footsteps point to the floor or ceiling, voices to a wall, and traffic to windows and door gaps.
- Soft furnishings and seals are the budget fixes. They tame echo and leaks, but they will not stop a neighbor's bass.
- Real sound blocking needs mass and airtight seals: dense walls, a solid-core door with a bottom seal, and well-sealed windows.
- Renters can do rugs, curtains and draft stoppers freely. Replacing a door or adding wall layers needs the landlord's agreement.
- If you are still choosing a home, test the noise during a viewing. It is far cheaper than fixing it later.

Why your apartment is noisy in the first place
Two different problems get called "noise". Airborne sound is voices, TV and traffic traveling through air and then through walls, windows and gaps. Impact sound is footsteps, dragged chairs and dropped objects that shake the structure itself and radiate from the ceiling or wall.
The two need different cures. Soft materials help with echo inside your own room and with some airborne sound. Impact noise needs a better floor build-up, which you rarely control as a tenant.
Buildings also differ. Standards bodies set targets for this. New York City's environmental protection department, in its residential noise control guidance, recommends floors reaching at least IIC 50 in living areas and IIC 60 in bedrooms for impact noise. For interior walls in residential buildings it suggests at least STC 50, and STC 60 for exterior walls, to give speech privacy and block outdoor noise. These are guidance figures from one city, not Albanian rules, but they are a useful yardstick when you compare buildings.
Diagnose before you spend
Most wasted money in soundproofing comes from treating the wrong surface. Spend twenty minutes listening first.
- Notice what you hear. Footsteps and thuds suggest the floor or ceiling. Voices suggest a shared wall. Traffic, sirens and street conversations suggest windows or gaps around the door.
- Try the hand test. Put your palm flat on the wall or floor while the noise is happening. If you feel vibration, the sound is traveling through the structure and soft items will do little.
- Try the blanket test. Press a thick blanket or pillow against the window or the suspected wall. If the noise drops clearly, that surface is the weak point.
- Check the door. A hollow door with a gap underneath lets in hallway and stairwell noise even if the walls are fine.
- Do it at the worst hour. Evening cooking, morning commutes and late-night TV all sound different.
Low bass and deep rumbles are the hardest to place, because they travel through walls, floors and ceilings at once. If that is your problem, expect the cheap fixes to disappoint and focus on structural options or a conversation with the neighbor.
Cheap fixes that help (and what they can realistically do)
The usual affordable list is rugs, soft furniture, curtains and fabric, plus sealing gaps around doors with weatherproofing, a door sweep or a draft stopper, as Apartment Therapy lays out. Here is how to rank them.
| Fix | Best for | Limits |
|---|---|---|
| Door sweep or bottom seal | Hallway and stairwell noise | Little help if the door itself is hollow and thin |
| Weatherstripping on door and window frames | Traffic and street voices | Must be continuous to work; gaps defeat it |
| Heavy curtains | Street noise, echo in the room | Reduces, never eliminates, sound |
| Thick rugs with a pad | Echo and some footstep noise from your own floor | Does not stop noise from the neighbor above |
| Bookcases full of books on a shared wall | Voices | Takes space; moderate gain |
| Large upholstered furniture | Echo | Almost no effect on noise from outside |
The New York guidance notes that carpeting reduces reverberant noise and that heavy draperies can significantly block or absorb noise. The key word is reverberant: a rug makes your room less echoey, which feels quieter, but it is not a barrier.
Seal the gaps first
Sound behaves like water: it finds the smallest opening. A thin gap under a door or around a window can undo the benefit of a good wall. German acousticians in the DEGA memorandum on sound insulation at home point out that a door reaching around 27 dB of insulation needs a continuous sealing system, such as a drop-down seal at the threshold. In practice, a few dollars of foam tape and a door sweep often deliver more than panels on the wall.
Be careful with foam panels and white noise
Thin acoustic foam panels absorb echo inside a room. They do not stop sound from passing through a wall, and they are marketed far more broadly than their effect justifies. Materials that do add blocking power include thin, dense mass-loaded vinyl and clear window inserts that create an airtight seal, as The Spruce notes, though they cost more and take effort to install.
White noise machines and fans mask sound. The NYC guidance is plain that masking does not reduce noise: it adds sound so that unwanted sounds are less noticeable. That can be enough for sleep, but it is a coping tool, not soundproofing.
What actually blocks sound: mass and airtight seals
If the neighbor's TV or the street is genuinely too loud, soft furnishings will not be enough. Sound blocking depends on mass, sealing and separation. According to the New York guidance, massive walls such as gypsum board constructions and solid-wood-core doors block sound more effectively than light ones.
The most effective upgrades, roughly in order of value for money:
- Solid-core door with a perimeter and bottom seal. The single best upgrade for corridor noise.
- Window upgrades. Sealed frames, heavier glass or a secondary inner window cut traffic noise the most.
- Added wall mass. An extra layer of dense board on the shared wall, ideally on resilient mounts, improves speech privacy. This is renovation work for owners.
- Floor build-up. A better underlay or floating floor reduces impact noise in your own unit, and is worth specifying in a renovation.
Get a local contractor to quote for these and ask what insulation rating the finished construction should reach. Without a target number, quotes are hard to compare.
Renters: what you can do and what needs permission
Renters can reduce noise with carpets and soft furnishings, curtains and weatherstripping for door and window gaps. Permanent structural changes require the landlord's consent, and Family Handyman suggests asking the landlord about replacing a flimsy hollow-core door with a solid-core one.
A sensible order for tenants:
- No permission needed: rugs with pads, lined curtains, draft stoppers, a bookcase on the shared wall, removable weatherstripping, furniture rearranged so beds are not against a noisy wall.
- Ask first: a new door, anything screwed into walls or ceilings, window inserts fixed to the frame, glued panels or new flooring.
- Put it in writing: if the landlord agrees to a door or window upgrade, record who pays and whether it stays when you leave. Landlords often agree when the upgrade adds lasting value to the property.
If the problem is a particular neighbor, a polite conversation, with specific times and sounds, solves more than most products do.
Owners: plan quiet into the layout
If you are renovating or buying, layout matters as much as materials. The DEGA memorandum suggests avoiding open floor plans in favor of closed layouts for effective noise reduction, and keeping sanitary fixtures off walls shared with sensitive rooms such as bedrooms. It also stresses that noises made inside your own home are a major source of disturbance, and that structural measures work better than relying only on masking or behavior.
One more finding is worth knowing: the same memorandum notes that annoyance from noise inside a home increases as outside ambient noise falls or as the insulation of external building parts improves. In plain words, once you seal out the street, you start hearing the neighbors and your own appliances. Plan the whole acoustic picture, not one wall.
A draft building code reviewed in the EU's technical regulation database, Germany's model building code, states that buildings need noise insulation appropriate to their use and that noise from fixed installations must be limited to avoid unreasonable irritation. Ask any developer how the building meets its local requirements, and ask for the actual figures rather than a promise of "good insulation".
Should you hear your neighbors through the wall?
Loud speech should not be clearly understandable through a well-built party wall. Faint murmurs are normal, particularly in older buildings. Using the STC 50 guidance for interior walls as a yardstick, a wall at that level makes normal speech hard to follow. If you can make out words at ordinary volume, the wall is weak, has gaps around sockets and ducts, or is a lightweight partition.
Before blaming the neighbors, check for flanking paths: shared pipes, open vents, and gaps at the top or bottom of the partition.
Check the acoustics before you rent or buy
The cheapest soundproofing is choosing a quiet apartment. A viewing is your chance to test it.
- Visit twice, once in the morning rush and once in the evening.
- Stand in the bedroom, close the windows and listen for 2 to 3 minutes. Then open them and hear the difference.
- Knock gently on shared walls. A hollow sound suggests a light partition.
- Look at the door and window frames. Visible gaps or a hollow door are cheap to fix. Thin single glazing on a busy road is not.
- Check what is above and beside you. Bedrooms against stairwells, lifts, bars or a neighbor's kitchen cause the most trouble.
- Ask the agent or owner directly about the neighbors, the building's age and any past complaints.
On Pelikani you can browse apartments and houses in the search results and contact verified owners and agents directly, so you can ask these questions before you travel to a viewing. Buyers and renters pay no fee on the platform. If you want a larger choice of agents, the agents directory lets you compare who handles which listings, and if you are setting up a new home, the internet service page saves you one more errand.
Our perspective
We see a lot of listings, and the photos almost never show what a home sounds like. Buyers compare price, size and location, then find out about the noise after they move in. Our advice is to treat sound as a selection criterion, just like natural light.
For tenants, we would spend a small amount on seals, a good rug and curtains, and keep the rest of the budget for moving to a quieter place if the problem is structural. Money spent on a flat that fails the bedroom test is rarely recovered. For owners and agents, being upfront about a building's quiet features, such as solid doors, good windows and a quiet side of the building, helps serious buyers decide faster. That is why we encourage direct contact with the person who knows the property, so questions about neighbors and construction get honest answers.

Quick plan by budget
Under a weekend and a small spend: door sweep, weatherstripping, a rug with a pad, lined curtains, a bookcase on the noisy wall.
A bit more, still renter-friendly: removable window insert if the frame allows it, a door seal kit, repositioning the bed away from the shared wall.
With landlord or owner approval: solid-core door with full seals, upgraded windows, an added dense layer on the shared wall, improved floor underlay.
When nothing works: if the noise is heavy bass or constant, the problem is the structure or the neighbor. Talk to the neighbor, then the building manager or landlord, and consider a move.
FAQ
What is the cheapest way to soundproof an apartment?
Seal the gaps. A door sweep, weatherstripping around doors and windows, heavy curtains and a thick rug cost little and make a noticeable difference to street and hallway noise. They will not stop strong bass or footsteps from above.
Do acoustic foam panels block neighbor noise?
Not much. Foam panels reduce echo inside your room, but they are too light to stop sound passing through a wall. For blocking, you need mass and airtight sealing, such as a dense extra wall layer or a solid-core door.
Can I soundproof an apartment I rent?
Yes, within limits. Rugs, curtains, draft stoppers and removable weatherstripping need no permission. A new door, wall layers or fixed window inserts are permanent changes, so ask your landlord first and agree in writing who pays.
Does white noise reduce noise in an apartment?
No. White noise masks unwanted sounds by adding other sound, as the NYC guidance explains. It can help you sleep, but the actual noise level in the room stays the same.
How can I tell where noise is coming from?
Listen to the type of sound. Footsteps suggest the floor or ceiling, voices a wall, and traffic the windows or door gaps. Feeling vibration with your hand on the surface means the noise travels through the structure.
