Noise from traffic, neighbours, or a shared wall can turn a bedroom from a sanctuary into a source of stress. You do not need a professional studio conversion to notice a real difference. Most of the improvement comes from sealing gaps, adding soft materials, and rethinking your layout.
How Do You Soundproof a Bedroom?
The most effective low-cost way to soundproof a bedroom is to seal gaps around the door and windows, hang thick curtains, add a rug with an underlay, and position large furniture such as wardrobes against shared walls. These changes target the three main ways sound enters a room: gaps, hard reflective surfaces, and thin shared walls.
Where Sound Actually Comes From
Before spending money, it helps to identify the source. Traffic and outside noise usually enter through windows and gaps around doors. Neighbours or housemates usually transmit sound through shared walls, ceilings, or hollow-core doors. Footsteps from above travel through the ceiling and are harder to fully resolve without ceiling work. Knowing which of these applies to your room helps you prioritise the right fix first.
10 Ways to Soundproof a Bedroom on a Budget
1. Seal Gaps Around the Door
Gaps under and around a door are one of the biggest, cheapest fixes to make. A door sweep at the base and adhesive weatherstripping around the frame close these gaps and reduce sound noticeably, while also improving energy efficiency.
2. Hang Thick Curtains
Heavy, lined, or thermal curtains absorb sound at the window, one of the main entry points for outside noise. Hanging them slightly wider than the window frame improves coverage further.
3. Add a Rug With an Underlay
A thick rug, ideally wool or another dense fibre, reduces both echo within the room and noise transfer to rooms below. Adding a pad underneath improves the effect without taking up more floor space.
4. Rearrange Furniture Against Shared Walls
Positioning wardrobes, bookcases, or other large furniture against a wall shared with a noisy neighbour or hallway adds mass that helps block sound transfer. This is one of the few soundproofing changes that costs nothing if you already own the furniture.
5. Add Soft Furnishings
Upholstered headboards, fabric wall hangings, and extra cushions or throws all give sound more surfaces to be absorbed into rather than bouncing around a room with mostly hard surfaces.
6. Consider Acoustic Panels
Acoustic foam or fabric-wrapped panels are a relatively affordable way to reduce echo and absorb sound, and many modern designs are attractive enough to double as wall decor.
7. Upgrade to a Solid-Core Door
Hollow-core doors, common in many budget-built homes, do very little to block sound. A solid-core door is noticeably heavier and denser, and swapping one in is one of the more effective mid-budget upgrades available.
8. Move Your Bed Away From the Noise Source
If a particular wall is the main source of disturbance, simply relocating your bed to the opposite side of the room can meaningfully reduce how disruptive the noise feels, even before any other changes.
9. Use a Fan or White Noise Machine
Masking remaining background noise with a fan, air purifier, or white noise app provides a steady, less disruptive sound that can make intermittent noises far less noticeable.
10. Upgrade Your Windows if Traffic Noise Is the Main Issue
If outside noise is the dominant problem, double or triple glazing offers the biggest structural improvement, though this is a larger investment than the other changes on this list and is worth considering only once the cheaper fixes have been tried.
Build Up Gradually
Start with the cheapest fixes, sealing gaps, rearranging furniture, and adding textiles, before spending on acoustic panels or a new door. Most bedrooms see a meaningful improvement from these budget-friendly changes alone, and it is easier to judge whether a bigger investment such as a solid-core door or new glazing is genuinely needed once the simple fixes are already in place.

Frequently Asked Questions
What is the cheapest way to soundproof a bedroom?
Sealing gaps around the door with weatherstripping, hanging thick curtains, and rearranging furniture against shared walls are the cheapest and most effective starting points, since they use materials many people already have or can buy inexpensively.
Do rugs actually help reduce noise?
Yes. A thick rug, particularly with an underlay, absorbs sound within the room and reduces how much noise transfers to the room below, which is especially useful in flats and multi-storey homes.
Will a solid-core door really make a noticeable difference?
Yes. Hollow-core doors offer very little sound resistance, so replacing one with a solid-core or pre-hung door is one of the more noticeable mid-budget upgrades for reducing noise from a hallway or adjoining room.
Can I soundproof a bedroom without any building work?
Yes. Sealing gaps, adding curtains and rugs, rearranging furniture, and using soft furnishings can resolve a large portion of most noise problems without any structural changes.
Is double glazing worth it just for noise reduction?
If traffic or outside noise is the main source of disturbance, double or triple glazing offers a significant improvement, though it is a larger investment best considered once cheaper fixes have already been tried.
Results vary depending on the construction of your home and the source of the noise. Combining several of these changes together tends to work better than relying on any single fix alone.
