Acoustic Performance & Sustainability

Sound Absorption Coefficient

Line graph showing absorption coefficient (α) rising from about 0.2 at 50 Hz to a peak around 1.0 near 2500 Hz, then slightly dropping at 5000 Hz. X-axis: 1/3 Octave Center Frequency (Hz). Y-axis: Absorption Coefficient (α).

Ljuds™ wood wool acoustic panels undergo ISO 354 testing to measure sound absorption across frequencies. The results show high efficiency, especially in the mid-to-high range, ensuring effective reverberation control.

Frequently Asked Questions

Diagonal 300 is a 300 × 300 mm wood wool acoustic panel with finely grooved diagonal lines designed for sound absorption and reverberation control on walls and ceilings in modern interiors such as offices, auditoriums, and hospitality spaces.

The diagonal grooves create a dynamic geometric texture that increases the panel’s surface area and helps trap sound waves, improving reverberation control and overall acoustic comfort when installed across large surfaces.

These panels are made from a blend of recyclable wood fibres and cement, forming an eco-friendly wood wool panel system that supports sustainable design practices while delivering effective sound absorption and moisture regulation.

Yes — wood wool panels naturally offer moisture regulation due to their open-pore structure, which can help maintain more stable indoor humidity and contribute to improved air quality compared with dense, non-breathable materials.

Absolutely — Diagonal 300 panels are durable and fire-resistant while delivering reliable sound absorption, making them suitable for high-traffic environments such as restaurants, schools, gyms, and offices where speech clarity and reverberation control matter.
