4sound® P04F02

A cladding system that combines geometric rigour and acoustic comfort. One of the latest additions to the collection, characterized by an exceptionally dense groove pattern. The surface is defined by a millimetric micro-alternation: 2 mm of solid wood interrupted by 2 mm voids created by the grooves, resulting in a total microscopic pitch of 4 mm. The 133 mm slat system ensures clean installation and visual continuity. The system is engineered to deliver optimized acoustic performance depending on the installation surface:

Ceiling Application (Black Curve)
• Tuned for outstanding acoustic absorption across the mid-frequency range.
• Maximum and stable performance between 500 Hz (0.97) and 1000 Hz (0.95).
• Highly effective reverberation reduction already at 250 Hz (0.85) and controlled response at 2000 Hz (0.83).

Wall Application (Green Curve)
• Optimized for targeted and high-performance acoustic correction in the mid frequencies.
• Exceeds 100% efficiency with a peak of 1.04 at 500 Hz and maintains 1.01 at 1000 Hz.
• Calibrated response at the edges of the spectrum, with 0.56 at 250 Hz and 0.73 at 4000 Hz.
