Acoustic functions
 |
Knauf Danoline acoustic ceilings absorb the sound waves in three ways: by the vibrations of the acoustical tiles, by the resonance created in the perforation holes and by the acoustic felt backing. |
|
Perforation holes create resonance in the acoustic tile and act sound absorbing on the mid-range frequencies. The acoustic felt on the back offers additional air resistance to the sound waves that pass through the perforation holes and absorb the high frequency sound. In addition, the acoustic felt smoothes out the sound absorption across the frequency range. Gypsum-based sound absorbers thus offer broad-band sound absorption across the frequency range and ensure optimal room acoustics. |
