Rectangle

Ljuds™ Rectangle offers a sleek, elongated design that enhances sound absorption and reduces reverberation. Made from recyclable wood fibres and a cement matrix, its porous structure effectively captures sound waves while regulating moisture. With high NRC ratings and fire resistance, Rectangle shaped panels provide a durable and versatile acoustic solution for offices, residences, and commercial spaces.

Three treadmills are lined up indoors next to large windows, with a view of green trees and an outdoor area visible through the glass. The interior features beige tiled walls and a wooden ceiling.

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

Ljuds™ Rectangle panels are made from recyclable wood fibres combined with a cement matrix. This eco-friendly composition creates a porous structure that absorbs sound waves and helps reduce reverberation in interior spaces.

The sleek, elongated Rectangle shape enhances sound absorption and lowers echo by increasing the surface area and directing sound into the panel’s open-pore structure. These panels have a high NRC (Noise Reduction Coefficient) rating, meaning they effectively reduce noise and improve speech clarity in rooms.

Rectangle panels are versatile and can be used on acoustic walls, ceilings or feature surfaces in offices, residences, auditoriums and commercial spaces. They help balance noise levels and improve overall acoustic comfort.

Yes. The panels are made from eco-friendly recyclable materials that support sustainable design. They also offer fire resistance and moisture regulation, making them a safe option for interior acoustic treatment.

Rectangle panels help reduce reverberation, control echo and enhance speech intelligibility. Their porous wood wool construction absorbs mid-to-high frequencies, making them ideal for spaces where clarity and noise reduction are priorities.
