Acoustic panels and soundproofing solve two different problems. Acoustic panels absorb sound inside a room, reducing echo and reverberation so the space sounds clearer to the people in it. Soundproofing, or sound insulation, stops sound passing between rooms and relies on heavy, sealed, decoupled construction — not absorptive panels. A slat panel will make a room sound better, but it will not stop a television being heard through the wall next door.
- Absorption and soundproofing are two different problems. Acoustic panels absorb echo and reverberation inside a room, while sound insulation stops sound travelling between rooms, relying on different physics and standards.
- Panels add almost no mass, so they cannot block transmission. A porous slat panel converts in-room sound to heat in its backing, but noise still passes through the wall much as before.
- Insulation is engineered into the building fabric. Adding dense sealed mass, sealing gaps and decoupling with resilient bars or an independent frame raises a wall's weighted sound reduction index (Rw).
- Diagnose by where the noise comes from. An echoey, harsh room is a reverberation problem for absorption; clearly hearing a neighbour through a wall is an insulation problem panels will not fix.
Absorption and soundproofing are two different problems
Acoustic panels control absorption — how much sound energy a surface soaks up rather than reflects back. More absorption means shorter reverberation and less echo, so speech, music and calls sound clearer to the people in the room. Soundproofing, properly called sound insulation, is a separate problem: stopping sound travelling between one room and another. The two rely on different physics and different standards, and one does not deliver the other.
Because they are separate problems, the fix for one rarely helps the other. Covering a wall in slat panels makes a room sound calmer without making it any quieter next door. Working out which problem you actually have is the honest starting point, and it saves both money and disappointment.

What gets sold as a 'soundproofing panel'
The phrase covers two product families that do opposite jobs, which is why the results for it are so confusing. The first family is absorbers: acoustic foam, polyester (PET) board, fabric-wrapped mineral wool, and slatted timber panels like ours. They are light, and they are deliberately open — porous, fibrous or gapped — so that sound can get into them and lose a little of its energy as heat. The second family is blocking materials: dense boards, acoustic plasterboard, mass-loaded barrier membranes, and the independent frames and resilient bars they are built onto. They are heavy, and they are sealed.
That gives you a check you can apply to any product page without knowing any acoustics. If a panel is light enough to stick to a wall with adhesive, and its face is open — foam cells, exposed felt, gaps between slats — it is an absorber. Openness and low weight are exactly the properties that let it absorb, and exactly the properties that stop it blocking. Nothing that blocks sound is light, and nothing that blocks sound has holes in it. Our panel is 9 mm thick, fixed with adhesive, and has felt showing in the gaps between the slats: an absorber, by that check and by design.
Why acoustic panels don't block sound between rooms
A wooden slat panel is a porous absorber: sound waves enter the felt or fabric backing, and friction converts part of that energy into heat. That only acts on sound already inside the room. Blocking sound between rooms instead depends on mass and decoupling — heavy, sealed, ideally separated layers that resist being set into vibration. A lightweight absorptive panel adds almost no mass, so noise passes through the wall much as before. This is explained further in how acoustic panels work.
How do I tell which problem I have?
Ask where the noise is coming from. If a room echoes, sounds harsh, or makes speech and video calls hard to follow, that is a reverberation problem inside the room — exactly what absorption is designed for. If you can clearly hear a neighbour's television, voices or footsteps through a wall, floor or ceiling, that is an insulation problem, and panels will not fix it. Many spaces suffer from both, but each needs its own solution.
What actually solves a sound insulation problem
Real insulation comes from construction, not from linings. Adding mass with a denser or doubled layer of plasterboard, sealing every air gap, and decoupling surfaces with resilient bars or an independent frame all raise a wall's weighted sound reduction index (Rw), the single-number rating for airborne sound insulation. For homes, Approved Document E sets the insulation required between dwellings, and it is met through mass and construction — never through absorptive panels.
Impact sound, such as footsteps or dropped objects, travels through the structure itself and needs resilient floor treatments or isolation rather than any wall lining. Whatever the path, the principle holds: insulation is engineered into the heavy, sealed building fabric, while absorption is simply added to the room's exposed surfaces. Confusing the two is a common and costly mistake to avoid.
Where acoustic panels genuinely help
Once you have confirmed a reverberation problem, acoustic panels are a proven tool. They shorten reverberation time, reduce echo and flutter, and make speech clearer in offices, classrooms, studios and busy rooms at home. Panels are chosen on their tested sound absorption coefficient, measured to ISO 354 and often summarised as a single αw value. For the specific question of hearing the neighbours, the honest answer is still construction — see do acoustic panels stop noise from neighbours.
Where our panel is the right tool — and who can actually buy it
Once you have established that the problem is inside the room, absorption is the right answer, and a slatted panel is a reasonable way to buy it: the felt behind the slats absorbs, while the slat profile scatters some of the higher frequencies rather than deadening the room flat. It shortens reverberation, cuts flutter and makes speech easier to follow — in an office, a studio, a hard-surfaced living room. The range is at acoustic slat wall panels.
Two limits, stated because you should hear them from us rather than find out later. First, we hold no test report for this panel, so we publish no absorption figure for it — not a coefficient, not a rating. What that means for a buyer is set out in what no test report means when buying panels. Second, we are a trade supplier and we sell by the pallet: 75 panels, roughly 110–206 m² depending on the size chosen. Someone treating one room cannot buy from us, and we would rather say so here than take the enquiry.
Frequently asked questions
Will acoustic panels stop noise from my neighbours?
No. Acoustic panels absorb sound inside your room to reduce echo and reverberation; they add almost no mass, so they do not stop airborne noise passing through a shared wall, floor or ceiling. Reducing neighbour noise requires added mass, sealing gaps and decoupling — a construction change, not a lining.
What is the difference between sound absorption and sound insulation?
Absorption soaks up sound energy inside a room, shortening reverberation and reducing echo; it is measured by the sound absorption coefficient. Insulation blocks sound travelling between rooms and is measured by the weighted sound reduction index (Rw). Different physics, different standards — panels deliver the first, not the second.
Do I need soundproofing or acoustic treatment?
If a room echoes or speech is hard to follow, you need acoustic treatment, which is absorption. If you can hear people or televisions through the wall, you need soundproofing, which is insulation. Some rooms need both, but each is solved separately — panels for the echo, heavier or decoupled construction for the transmission.
Can any wall panel improve sound insulation?
Only if it adds significant sealed mass or decoupling, which typical absorptive wood slat panels do not. Their felt backing is porous and lightweight, designed to absorb sound within the room. For measurable insulation gains you need dense, sealed, ideally decoupled construction, assessed against Approved Document E for dwellings.
