Frequently Asked Questions
How do wooden perforated acoustic panels work to reduce noise?
They function as Helmholtz resonators. Sound waves enter through precisely drilled holes and travel into the air cavity behind the panel (often filled with absorbing material). The sound energy is trapped and converted into heat energy through friction, effectively reducing echoes.
How many panels do I need to treat a room?
A general rule is covering 25-30% of reflective wall surfaces for noticeable reduction. For critical listening environments like studios or theaters, you may require 40% or more coverage.
How do I clean and maintain these panels?
Dusting or wiping with a slightly damp cloth a few times a year is sufficient. Avoid getting the felt backing wet. You can apply specific wood maintenance oil to natural veneer panels to revitalize them over time.
Can these panels be used for ceiling applications?
Yes, perforated MDF panels are suitable for both wall and ceiling installations using the appropriate keel or clip system to ensure safety and acoustic performance.
What is the difference between Natural and Engineered Veneer?
Natural veneer offers unique, random patterns with natural variations. Engineered veneer is more consistent and uniform, utilizing sustainable wood fibers to create consistent grain patterns across large projects.
Are the panels fire-resistant?
Yes, the panels are available in Class B or Class A fire ratings, depending on the core material selected and project requirements, meeting international building safety standards.
