Common questions, in plain language.

No, and we would rather be honest than oversell. Total silence is almost never realistic or necessary. What we do is reduce noise to a measured, agreed target, so intrusive sound drops below the level that disturbs sleep, focus or privacy. We measure the actual noise first, design to a specific decibel goal, then verify the result before and after. A big, honest improvement rather than an empty promise.

It depends on the room size, the noise target and how your building is already constructed, so we do not quote a fixed figure blind. Sealing a door or fitting secondary glazing is modest; a full room-in-room studio is a larger investment. We give you an honest price range after a free noise assessment, based on the actual problem rather than guesswork. Call +233 20 531 3333 to book yours.

Yes. Before we quote anything, we come to your space, measure the actual noise in decibels and trace exactly where sound is getting in or out. Most noise problems have one specific weak path, and treating the wrong one wastes money. The assessment tells us the real target and the honest cost to reach it.

Most residential rooms are completed within a few days, depending on how much decoupling or construction is involved. Simple work like door seals or secondary glazing can be same-day. Larger commercial fit-outs, studios or generator enclosures take longer, and we set a realistic timeline at the survey so you know exactly what to expect. We plan the work to limit disruption to your home or business.

We guarantee our workmanship and we commit to a measured noise target agreed with you in writing. Because every building is different, we prove the result rather than just promise it: we measure decibels before we start and again when we finish, so you can see the improvement. We do not promise total silence; we promise a verified, honest reduction to your target. Warranty terms are set out in your quote.

Often, yes. Many effective fixes add little disruption: secondary glazing over existing windows, engineered door seals, decoupled overlays on a wall or ceiling, and sealing hidden gaps. These can lift performance significantly without stripping your room back to the structure. Where deeper work is needed we can phase it around your life or business. At the assessment we tell you honestly which route fits your building and budget.

We work across Greater Accra, Tema and Kumasi, and we travel beyond these for larger projects. Whether you are a homeowner, an office, a clinic, a studio, a church or an industrial site, we can usually reach you. If you are further afield, call us and we will confirm honestly whether we can serve your location well. Reach us on +233 20 531 3333.

Some fixes you can do yourself, like fitting door seals or hanging heavier curtains, and we are happy for you to. The biggest and most common waste of money, though, is treating the wrong path, for example bolting foam to a wall when the noise is coming through the window. A short assessment shows where the sound really travels, so any money you spend, yours or ours, actually works.

That is airborne noise passing through the wall, and the fix is a system, not a single product. We add mass, decouple the surfaces so vibration cannot pass straight through, and seal every flanking gap around sockets, skirting and junctions where sound sneaks past. Foam alone will not do it. After a survey we design the wall build-up to a measured privacy target and verify it before and after.

Footsteps are impact noise, travelling through the structure itself, so adding mass to the wall does little. The answer is at the floor or ceiling: a decoupled ceiling on isolation hangers, or a floating floor with resilient underlayment above, which breaks the path the thud travels through. We measure the impact level, target a specific improvement and verify it. It is a different problem from airborne neighbour noise.

Windows are usually the weakest point, so they are often the best value to fix first. Secondary glazing, a second decoupled pane set in a deep cavity with high-performance seals, blocks far more than a single sheet of glass, and we seal the frame and any surrounding gaps too. For generators we also treat the noise at its source. We measure the actual level and design to a specific target.

That echo is a reflection problem inside the room, so it needs acoustic treatment, not soundproofing. Adding absorption, such as fabric-wrapped panels or ceiling clouds, soaks up the reflections that make your voice sound hollow and boomy on calls. This is a different job from blocking sound between rooms, and it is often quick and affordable. We measure the reverberation and add just enough absorption to make speech clear.

A home cinema needs two things done together: blocking, so the bass and action do not travel through the house, and treatment, so the room itself sounds clean and controlled. We build up the walls, ceiling and door for isolation, then tune the room inside with absorption and bass control. Low frequencies are the hardest to contain, so we set an honest target at the survey and verify the result.

For sleep we treat the whole envelope of the room, because noise gets in through the weakest point, usually the window, then the door and walls. We seal and upgrade each path to reach a night-quiet interior target, guided by the level that protects rest. If a generator, road or neighbour is the source, we identify which path carries it most and prioritise that. We measure before and after.

A studio needs room-in-room construction using all four pillars, mass, damping, decoupling and absorption, so sound does not leak out to the street or to neighbours, and so complaints never start. Inside, we tune the acoustics with bass traps, diffusion and first-reflection control so recordings sound accurate. We design to a measured isolation target, mindful of Ghana's GS 1222:2018 limits, and verify the build before and after.

A loud restaurant is usually a reverberation problem: hard floors, glass and bare ceilings let sound build up until guests strain to talk and leave sooner. Surveys suggest most diners avoid noisy restaurants, so this is about revenue as much as comfort. We add absorption in ceilings and walls to cut the din while keeping speech clear and the room lively. We measure the reverberation and tune it to a comfortable target.

Speech privacy is both an ethical and a legal duty, and in Ghana the Data Protection Act, 2012 (Act 843) reinforces it. Overheard consultations need a system: blocking the wall and door so speech does not carry, absorption to reduce reflection, and often sound masking, a soft background sound that covers residual speech. We assess how much is leaking, then design to a privacy target so conversations stay confidential.

Ghana's EPA enforces ambient noise limits under GS 1222:2018, and churches, mosques, bars and clubs are expected to comply, with inspectors active especially in the festive season. The right approach is containment at the source: raising the mass and decoupling of the building envelope, and controlling low frequencies, so your programme continues without disturbing neighbours. We measure your emissions, design to keep you within the code, and verify the result.

They solve opposite problems. Soundproofing blocks sound from passing between rooms, using mass, decoupling and sealing. Foam panels are acoustic treatment: they absorb reflections inside a room to reduce echo, but they add almost no blocking, so your neighbour will still hear you. Putting foam on a wall to stop noise getting through is the most common and costly mistake. Many rooms need both, but for different reasons.

No. Egg-crate foam only reduces echo inside a room by absorbing some reflections; it adds almost no blocking between rooms, so it will not stop your neighbour, the generator or the traffic. It is light and thin, and real blocking needs mass, decoupling and sealing. Foam has its place for controlling echo in a studio or on a call, but it is not soundproofing and should never be sold as such.

STC, or Sound Transmission Class, rates how well a wall, door or floor blocks airborne sound; higher is better. As a rough guide, around 30 means speech is still audible, around 50 is the threshold considered adequately private between dwellings, and around 60 means speech is inaudible. Studios and cinemas aim higher still. Think of it like an SPF rating for noise, a useful guide, not a promise of silence. We design to the STC your goal needs.

NRC, or Noise Reduction Coefficient, is an absorption score from 0 to 1 that tells you how much sound a surface soaks up inside a room, where 1 absorbs almost everything and 0 reflects it back. It is about echo and reverberation within a space, not about blocking noise from reaching your neighbour. You use NRC to make a room sound calmer, and STC to keep sound in or out. Different numbers for different jobs.

Effective soundproofing rests on four pillars: Mass blocks sound, Damping turns vibration into heat and kills resonance, Decoupling breaks the physical path so vibration cannot pass straight through, and Absorption cleans up sound inside the room. Any one on its own underperforms; together they multiply. Think of four locks on one door. We assess which pillars your problem needs and combine them to reach your measured target.

Because of the mass law: with a single solid wall, every doubling of mass buys only about five to six decibels, so making one layer thicker gives diminishing returns for a lot of weight and cost. The heavy lifting comes from decoupling and damping, separating two masses with an air gap and adding a viscoelastic layer between rigid boards. That is why a well-designed wall beats a merely thick one.

Flanking is sound taking a route around your barrier rather than through it, along shared floors and ceilings, through ducts, gaps, door undercuts or back-to-back electrical sockets. A perfectly built wall means nothing if sound flows around it, and even a one per cent gap can cost around ten decibels. Sealing and treating these hidden paths is essential, which is why our survey traces every route before we design.

Low bass is the hardest sound to block, because long wavelengths carry a lot of energy and pass easily through light structures. It is not impossible, but it demands the full toolkit: substantial mass, decoupling to break the path and damping to kill resonance, and it costs more than treating everyday speech or traffic. We are honest about this, setting a realistic target at the survey and verifying what we achieve before and after.

It can, because good soundproofing depends on sealing gaps, and the same gaps often let air move. That is why we design ventilation and cooling in from the start, using acoustic vents and silenced air paths, or coordinating with your AC, so a quiet room does not become a stuffy one. This matters especially in Ghana's climate. We plan airflow and acoustics together rather than fixing one and breaking the other.

Ghana sets ambient noise limits under GS 1222:2018, enforced by the EPA. As a guide, residential areas allow around 55 dB(A) by day and 48 dB(A) at night, and commercial areas around 75 by day and 65 at night, with education, health and office settings lower again. We design your project to keep you within the code, measure your actual levels, and document compliance so you are protected.

Yes, this is a real risk in Ghana, not a scare tactic. The EPA enforces the GS 1222:2018 noise limits and can act on complaints, and neighbours can bring nuisance claims, which is how venues elsewhere face fines or closure. Containing your noise at the source protects your operations and your reputation. We measure what you emit, design to keep you within the code, and verify the result before you rely on it.

Yes, and it is one of the most common problems we solve in Ghana. Generator noise is best tackled in two places: an acoustic enclosure or canopy around the genset itself, with exhaust and intake silencers and balanced ventilation so it does not overheat, and the wall or window path where that noise enters your living or working space. We measure the level, target a specific reduction, and verify the result.

We cannot switch off a source outside your control, but we can raise your building's ability to keep that noise out. By upgrading the windows, doors and walls of the affected rooms, and sealing the hidden paths sound uses, we bring the inside down to a sleep-friendly level even while the outside stays loud. We measure the intrusion, agree a realistic night-quiet target, and verify how much we achieve.
