Calculateur de Surface de Panneaux Acoustiques

Comparez la surface frontale des panneaux et l'absorption estimée avec la surface de la pièce, à partir d'un objectif de référence saisi explicitement.

Effective absorption19.0sabins
Achieved coverage20.1%

Effective coverage multiplies panel face area by the entered absorption coefficient. Use the coefficient for the frequency band that matters, not a marketing average.

Fonctionnement

How to use it: enter the room dimensions, subtract openings, then enter a reference coverage percentage and one panel size. The percentage is a quantity comparison, not a treatment prescription.

Formula. Panel count = ceiling(net room surface x target / panel effective area).

Example. A 0.6 by 1.2 m panel with coefficient 0.85 contributes 0.612 metric sabins.

Avant d’utiliser le résultat

  • Measure from the datum or reference edge described by this tool, and do not mix inside, outside and centerline dimensions.
  • Keep inputs in the displayed units and preserve more precision than the final cutting or purchasing tolerance requires.
  • When the result is close to a limit, verify it with a test piece, field measurement, manufacturer drawing or qualified project professional.

Limites

Coverage percentage is a materials estimate, not an acoustic diagnosis. Panel placement, thickness, air gap, scattering, bass trapping and frequency-specific coefficients determine performance. Do not cover reflective surfaces blindly.

Questions fréquentes

Should floors and ceilings count?

They are included in gross surface area. If you only plan to treat walls, set a target with that practical scope in mind and use the result as a quantity comparison.
