Impact Resistant Perforated Wood Acoustic Panel for School Classroom Noise Control

Yes - it is function based on the principle of a Helmholtz resonator . Sound waves enter the panel through the precisely drilled holes and travel into the air cavity behind the panel (which is ually filled with sound-absorbing material like acoustic foam or mineral wood). Inside this cavity , the sond energy is trapped and coverted into heat energy through friction . This process effectively reduces echo and reverberation within a room , leading to clearer sound .

As a general rule , covering 25-30% of your reflective wall surfaces is a good starting point for noticeable echo reduction . However , the exact number depends on the room's size , the type of furniture , and how you use the space . For critical listening environments like home theaters or recording studios , you may need to cover 40% or more . It's best to prioritize 'first reflection points' the spots on walls where sound dounces directly from your speakers to your ears.

Maintenance is relatively simple . For regular care , dusting or wiping the slats with a slightly damp cloth a few times a year is usually sufficient . Avoid getting the felt backing wet . For wood panels that appear dry over time , you can apply a specific wood maintenance pil revitalize them , approvimately 500ml of oil is enough for 6-8 panels , depending on the wood type .

Core thickness options include 15mm, 18mm, and 21mm MDF.

Typically mounted on a fireproofing wooden frame with invisible split battens, or on 50mm softwood battens with mineral fibre in the cavity.
