How do acoustic felt panels work?

PET felt acoustic panels are exceptionally effective at absorbing sound thanks to their dense, porous structure. They work by converting the energy of sound waves into small amounts of heat. When a sound wave hits the panel, it travels through the fibers, creating friction that dissipates the sound energy. This process significantly reduces reverberation and background noise, helping create a quieter and more comfortable environment.

Absorption and diffusion – two functions of felt panels in one

Although acoustic panels are primarily known for their sound-absorbing capabilities, some variants – especially those with complex structures or patterns – can also function as sound diffusers. Diffusers scatter sound waves in multiple directions, preventing unpleasant echoes and flutter echo. As a result, the room achieves a more natural and balanced sound, which is particularly important in spaces with demanding acoustic requirements.

Popular types of felt acoustic panels

• Flat PET felt sheets: dense, simple panels available in various thicknesses 9 mm, 12 mm and 24 mm. They are ideal for creating clean, minimalist wall and ceiling surfaces while delivering excellent acoustic performance.
• Decorative acoustic tiles: modular shapes that can be arranged in virtually any pattern – much like pieces of art. These tiles are often used to personalize walls in home offices, recording studios, and commercial interiors, combining acoustic performance with visual appeal.
• Felt office accessories: functional solutions such as acoustic room dividers, acoustic artworks, and acoustic baffles help reduce noise in open-plan offices. They create quieter zones for focused work, improving both comfort and productivity.
