Tile floors, concrete shells, glass walls: Cambodia builds beautiful echo chambers. Acoustic wall decoration fixes the noise without hiding it behind grey office foam - the treatment becomes the design feature. Here are the options, the numbers, and where to use each one.
Walk into most new restaurants or hotel lobbies in Phnom Penh at peak hour and the problem is audible: hard surfaces bounce every voice back into the room, the noise floor climbs, guests lean in and shout, reviews mention "loud" without quite knowing why. The fix is absorption on the walls - and the current generation of acoustic products is designed to be looked at, not hidden.
Six kinds of acoustic decoration that actually work
- PET felt panels and shapes. Recycled polyester felt cut into tiles, fins, geometric mosaics or custom shapes, in dozens of colors. Light, durable and the most design-flexible absorber on the market.
- Timber slat acoustic walls. Wood slats on a black acoustic felt backing - the signature look of 2026 hospitality interiors, equally at home behind a reception desk or a restaurant banquette.
- Fabric-wrapped panels. An absorptive core wrapped in your chosen textile, made to size. The premium option for boardrooms, suites and theatres - see our wall fabric guide.
- Printed acoustic art. Your artwork or photography printed on an absorptive canvas or felt core. Decor and treatment in literally the same object.
- Acoustic wallcoverings. Roll goods with absorptive texture for full-wall coverage where panels would clutter the design - corridors, KTV, cinema rooms.
- 3D sculpted panels with backing. Relief panels that scatter and absorb sound - the feature-wall route, covered in depth in our 3D panel guide.
The numbers: how much each option absorbs
| Solution | Typical NRC |
|---|---|
| Acoustic wallcovering (roll) | 0.20 - 0.40 |
| Timber slat panel on felt | 0.60 - 0.90 |
| PET felt panels (with air gap) | 0.80 - 0.95 |
| Fabric-wrapped panels | 0.85 - 1.00 |
| Printed acoustic art | 0.70 - 0.90 |
Design ideas by space
Restaurants and cafes
Slat wall behind the counter or along the main dining wall, printed acoustic art over tables, padded banquette backs. Target the walls guests face when speaking - that is where reflections do the damage.
Hotel lobbies
A full-height timber slat feature wall behind reception does double duty: brand moment and absorber. Add felt baffles or wrapped panels above lounge seating where ceilings are high.
Meeting rooms and offices
Fabric-wrapped panels at seated head height on two adjacent walls transform speech clarity and video-call quality. Felt mosaics let you bring brand color into the treatment.
KTV, cinema and casino spaces
Full-coverage acoustic wallcovering or suede plus padded panels - these rooms need absorption on most surfaces, and the materials read as luxury rather than treatment.
Two specification notes for Cambodia
Fire rating: for hotels and public buildings, specify panels with Class A (ASTM E84) or EN 13501-1 documentation - our fire-rating guide explains what to ask for. Humidity: PET felt and treated timber slat systems handle tropical interiors well; keep absorptive cores out of wet zones. Every product we supply ships with a data sheet within one working hour, batch-locked under a signed Spec Lock Certificate.
