Acoustic Panel
01
Popular wood strip sound-absorbing panels in Europe
Material and structure
Main material: European local hardwood (such as oak, walnut, pine) or sustainable forestry certified wood (FSC/PEFC), some products are combined with MDF or high-density fiberboard as the base material.
Structural design:
The strips are arranged in parallel, with an adjustable spacing of 5-20mm to form an open pore structure (as shown in the figure);
Sound-absorbing cotton (such as polyester fiber, rock wool) or perforated backboard is often pasted on the back to enhance the sound absorption effect.
Acoustic performance
Sound absorption coefficient (NRC): usually up to 0.6-0.9 (frequency 500-4000Hz), adjustable according to the spacing, thickness and sound-absorbing layer material of the wood strips.
Noise reduction principle: sound waves enter the sound-absorbing layer through the gaps between the wood strips, and are converted into heat energy consumption through fiber friction, reducing echo and noise reflection.
Environmental protection and certification
Formaldehyde emission: meets European E1 standard (≤0.124mg/m³), high-end products can reach E0 or formaldehyde-free glue certification (such as the German Blue Angel logo).
Sustainability: Most of the wood comes from sustainable forests in Northern Europe or Central Europe, and some brands use recycled wood for recycling.
