Noise & Soundproofing Problems
Unwanted noise is airborne or impact, and travels by direct and flanking paths. The right fix depends on diagnosing how the sound actually reaches you.
Why can I hear my neighbours through the wall?
Hearing your neighbours through a wall means sound energy is finding a path from their home into yours — and that path is not always the wall itself. Whether it is voices, a television or music, the noise is travelling either directly through the dividing structure or indirectly through the surrounding floors, ceilings and junctions. Understanding which path dominates is the key to reducing it, because soundproofing the wrong element wastes money.
Read the guideWhy can I hear footsteps from the flat above?
Footsteps, dropped objects and moving furniture from the flat above are impact sound — vibration created directly in the floor structure and radiated into your ceiling below. It is a different problem from hearing voices, and it is notoriously harder to stop, because the energy is injected straight into the structure rather than travelling through air first. Understanding impact sound is the key to treating it effectively.
Read the guideHow do I soundproof a room properly?
Soundproofing a room properly is not about sticking foam on the walls or adding a single layer of board — it is about understanding how the noise reaches the room and then applying the right combination of mass, isolation, sealing and absorption to the elements that matter. Done in the wrong order, or to the wrong surface, soundproofing disappoints. Done with a diagnosis first, it works.
Read the guideDoes soundproofing actually work?
Soundproofing does work — but only when it is based on a correct diagnosis, applies the right principles, and is judged against realistic expectations. Most disappointment comes from treating the wrong path, using products that address echo rather than transmission, or expecting silence where significant reduction is the honest goal. This guide explains what soundproofing can and cannot achieve, and why diagnosis is what makes the difference.
Read the guideHow do I reduce traffic and outside noise?
Traffic and outside noise gets into a home mainly through its weakest acoustic paths — the windows, any gaps and vents, and sometimes lightweight elements — rather than through solid masonry walls. So reducing it is about finding and improving those weak links, especially the glazing and air gaps, while being careful not to simply seal away the ventilation the room needs. The most effective measures target where the sound actually enters.
Read the guideWill new windows or secondary glazing reduce noise?
New windows usually reduce outside noise, and for many homes they are the most effective single step because windows are the weakest link in a wall's sound insulation — but secondary glazing is often even better, because its wide air gap and independent panes block sound across a broad range of frequencies. Which is right depends on how much noise reduction you need, whether the windows leak air, and whether you want to keep the original windows. And in every case, sealing the gaps and managing ventilation are part of getting it right.
Read the guideWhy can I hear everything in my new build?
New builds can be surprisingly noisy because modern construction is often lightweight — timber or steel frame, plasterboard partitions, engineered floors — which blocks airborne sound less than heavy masonry, and because sound frequently travels by indirect 'flanking' routes through the connected structure rather than straight through the wall you blame. Add the gaps and service penetrations common in fast modern building, and you can hear neighbours, footsteps and conversations clearly. The key to fixing it is finding the real sound paths, which are rarely the obvious ones.
Read the guideHow do I soundproof a party wall in a terraced house?
Soundproofing a party wall in a terraced house can work very well, but only if it is done in response to how the sound is actually reaching you. The instinct is to line the shared wall, yet in many terraces the neighbour's noise is not coming straight through the masonry — it flanks around it through the floor joists, the chimney breast, the ceiling void and the junctions. Lining the wall alone then makes a disappointingly small difference. The reliable approach is to diagnose the dominant transmission path first, decide whether the problem is airborne (voices, television) or impact (footsteps, doors), and then build the right amount of mass, separation and damping where it counts.
Read the guideWhy can I hear noise from the flat below?
Hearing the flat below — conversation, the thump of a television's bass, music or plumbing — is a different problem from hearing the flat above, and it is often more frustrating because it feels harder to place. The noise from below is usually airborne sound rising through the separating floor and flanking up the walls and around the junctions, rather than impact sound. Because the source is beneath you, treatments applied to your own floor surface do little; the sound is passing through the structure and arriving via paths you cannot see. The reliable fix starts with identifying whether the dominant path is the floor itself or flanking through the walls, then adding mass, isolation and absorption where the assessment shows it counts.
Read the guideDo I need soundproofing or acoustic treatment?
Soundproofing and acoustic treatment are often confused, but they solve completely different problems — and buying the wrong one is a common, costly mistake. Soundproofing reduces the noise passing between spaces: stopping the neighbours, the traffic or the room next door from being heard. Acoustic treatment controls the sound within a room: reducing echo, reverberation and harshness so the space sounds better and speech is clearer. Acoustic panels will not stop your neighbours, and mass-loaded soundproofing will not cure a room that echoes. Which you need depends entirely on whether your problem is noise coming through the structure or sound bouncing around inside the room — so the first step is to identify which it is.
Read the guideHow do I soundproof a ceiling from upstairs noise?
Noise from upstairs — footsteps, furniture moving, thuds — is mostly impact sound: vibration transmitted directly through the floor structure into the ceiling below, where it radiates as noise. That makes it harder to treat than airborne sound, because it travels through the structure itself, including by flanking paths around the edges. Effective ceiling soundproofing therefore has to add mass, decouple the ceiling from the structure, and absorb sound within the cavity — and ideally treat the impact at the floor above too. Understanding whether the problem is impact noise, airborne noise, or both, is the key to choosing a solution that works rather than wasting money on a partial one.
Read the guideWhy is my flat so noisy, and what can I do?
Flats are often noisy because they share walls, floors and ceilings with neighbours, and sound travels through all of them — directly through the separating structure and indirectly by flanking paths around the edges. You may hear airborne noise (voices, TV, music) through party walls and floors, impact noise (footsteps, doors) through the structure, and noise that seems to come from nowhere because it is flanking through the building's frame. Older conversions are usually worse than purpose-built blocks because the separating construction was never designed for sound. What you can do depends on which paths dominate, so diagnosis comes before any soundproofing.
