How wooden slat panels absorb
The slats look solid but they're spaced 5-15 mm apart. Sound waves pass between the slats to the acoustic backing (usually PET or wood-wool), where absorption happens. The wood face is decorative; the acoustic work happens behind it.
This design lets the slats be substantial (10-25 mm thick) while remaining acoustically transparent. Solid wood panels reflect sound; slat panels absorb it.
Where wooden slat panels fit best
Boutique hotels and restaurants with biophilic design language. The slats echo natural textures used elsewhere in the fit-out.
Premium residential home theatres and media rooms where the acoustic panel needs to look like a design feature rather than an acoustic afterthought.
Reception areas and lobbies where the acoustic work has to be visible-but-elegant.
Species, finishes, and durability
Standard species: oak, walnut, teak, MDF with wood veneer. Solid wood slats last decades but cost more; MDF-veneer is cheaper and still delivers the visual.
Finishes: natural oil, matte lacquer, or stained. Choose based on the interior palette.
For high-humidity environments (bathrooms adjacent to media rooms, tropical coastal properties), specify a properly-sealed finish. Otherwise wood may warp over time.
Acoustic performance considerations
Acoustic backing choice matters more than slat choice for performance. PET-backed slat panels: NRC 0.7-0.8. Wood-wool-backed: NRC 0.7-0.85. Fibreglass-backed: NRC 0.85+.
For premium acoustic performance, specify fibreglass or wood-wool backing behind the slats. For balanced performance-vs-cost, PET is the middle-ground.
