Sound Absorption Perforated Wood Acoustic Ceiling Panel for Conference Room

Product Description

2/2/0.5mm micro perforated acoustic panel

These micro-perforated acoustic panels are manufactured using precision micro-perforation technology, with a specification of 2/2/0.5mm (hole spacing 2mm, row spacing 2mm, hole diameter 0.5mm). The panel surface is covered with ultra-fine holes measuring only 0.5mm in diameter, which are nearly invisible to the naked eye. This allows the panels to retain the pristine and aesthetic appearance of the original surface finish.

 

In terms of acoustic performance, the micro-perforated structure efficiently absorbs sound wave energy, effectively reducing indoor reverberation and echo, and significantly improving the overall acoustic quality of the space. Our products perfectly combine high-efficiency sound absorption with modern decorative aesthetics. The discreet and subtle detailing ensures that they not only meet stringent acoustic engineering requirements but also preserve the visual harmony of any interior environment.

 

Leveraging the dual advantages of high-efficiency sound absorption + excellent decorative finish, the 2/2/0.5mm micro-perforated acoustic panels are widely applied in a variety of high-end commercial venues (such as conference rooms, concert halls, hotel lobbies, and office spaces) as well as residential projects (including home theaters and Hi-Fi listening rooms). They are the ideal choice for modern interior acoustic renovation and spatial noise reduction upgrades.

3 : NRC0.9 - test item sound absorption coefficient

The sound absorption performance of our products has been rigorously tested, achieving an actual Noise Reduction Coefficient (NRC) of up to 0.90, with the sound absorption coefficient as the tested item. The test method strictly complies with the international standard ISO 354:2003 "Acoustics — Measurement of sound absorption in a reverberation room." The acoustic performance measurements were conducted in a professional reverberation room, ensuring the scientific validity and authority of the testing data.

 

Notably, our products have passed rigorous testing by SGS, a globally authoritative third-party inspection organization, and we possess the official test report which holds legal validity and international credibility. This report serves as a solid, verifiable endorsement of our acoustic performance, with fully traceable data.

 

This means that in actual engineering applications, these micro-perforated acoustic panels can efficiently absorb sound wave energy, significantly reducing indoor reverberation time (RT) and echo interference. The combination of a high NRC value of 0.90 and the authoritative SGS certification provides a solid and reliable basis for material selection and quality assurance for your high-end commercial spaces, conference rooms, concert halls, or home theater projects.

4 : Fireproof result - Class A

The fire-retardant properties of our products have been rigorously tested and officially rated as Class A. This rating is strictly evaluated in accordance with ASTM E84, the Standard Test Method for Surface Burning Characteristics of Building Materials. During the testing process, both the Flame Spread Index (FSI) and Smoke Developed (SD) are comprehensively and precisely assessed.

 

According to the authoritative test report, our material successfully achieves the Class A classification (FSI ≤ 25 and SD ≤ 450). This outstanding performance indicates that in the event of a fire, the product can effectively inhibit the rapid spread of flames across the surface and significantly minimize the generation of toxic smoke, thereby providing precious time for the safe evacuation of occupants.

 

With its superior flame-retardant properties and robust safety guarantees, our Class A fireproof acoustic panels are the ideal choice for a wide range of public and commercial projects with stringent fire safety requirements, such as airport terminals, hospitals, schools, large commercial complexes, theaters, and high-end office buildings.

5 : Eco-friendly test Formaldehyde 0.05mg/m³

Our products have undergone rigorous eco-friendly emission testing. The formaldehyde emission level is measured at an impressively low ≤ 0.05mg/m³, demonstrating superior environmental safety. This testing strictly adheres to a comprehensive set of international standards, including ISO 16000-9:2006/COR1-2007, ISO 16000-6:2021, and ISO 16000-3:2022.

 

During the precise testing procedure, the Environmental Chamber method is utilized according to the standard requirements. Air samples are meticulously collected using Tenax-TA adsorption tubes and DNPH (2,4-dinitrophenylhydrazine) cartridges. The captured compounds are then qualitatively and quantitatively analyzed using advanced analytical instruments, specifically a Thermodesorption system coupled with Gas Chromatography (GC) and High-Performance Liquid Chromatography with Diode Array Detection (HPLC-DAD).

 

This rigorous multi-method analytical process ensures that any volatile organic compounds, especially formaldehyde, are accurately quantified. The resulting emission value of ≤ 0.05mg/m³ is far below the stringent safety thresholds for indoor air quality. This makes our micro-perforated acoustic panels an ideal choice for environmentally sensitive spaces such as schools, hospitals, kindergartens, and high-end residential projects. The reliable test data guarantees a safe, non-toxic, and healthy indoor environment for all occupants.

FAQ

Q: How do wooden perforated acoustic panels work to reduce noise ?
A: 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 .

Q: How many panels do I need to treat a room ?
A: 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.

Q: How do I clean and maintain wooden acoustic panels ?
A: 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 .
