Multifunctional Sound-absorbing Panel is a 21 mm MDF acoustic grille panel designed for interior wall applications where sound absorption and decorative finishing are required together. Its open grille structure allows reflected sound to reach the acoustic layer behind the panel, helping control reverberation in offices, conference rooms, hotels, apartments and other interior spaces.

Product Features
Open Grille Supports Sound Absorption
The hollow MDF grille leaves open areas across the panel surface, allowing reflected sound to pass through to the acoustic backing while maintaining a decorative wall surface.
21 mm MDF Provides Structural Stability
The 21 mm MDF grille forms the main structure of the panel, providing a solid and consistent surface for interior wall installation.
Integrated Design Combines Acoustics and Decoration
The MDF grille and acoustic backing are combined into one panel, allowing sound-absorbing treatment to be integrated directly into the decorative wall finish.
Up to GB Class A Fire Performance
The panel is available with fire performance up to GB Class A, providing a fire-rated option for interior wall applications where defined fire performance is required.

Quality Control
Dimensional Inspection
Panel length, width and thickness are checked against the confirmed product specification to maintain dimensional consistency across the order.
Grille Inspection
The grille is inspected for pattern consistency, spacing, alignment and visible machining defects.
Surface Inspection
Finished panels are checked for scratches, surface damage, finishing defects and noticeable color variation.
Final Pre-Shipment Inspection
Before packing, the finished order is checked against the confirmed specification and quantity, while packaging is inspected for proper product protection.

FAQ
Q: What NRC rating should I look for when choosing an acoustic wall panel?
A: Compare the NRC value together with the test standard, panel construction and mounting condition. A higher NRC does not represent the same installed performance under every mounting condition.
Q: Which acoustic test standards are commonly used for wall panels?
A: ASTM C423 and ISO 354 are commonly used laboratory methods for measuring sound absorption performance.
Q: Does a higher NRC mean better acoustic performance for every room?
A: No. Room size, surface area treated, mounting condition and frequency range also affect the final acoustic result.
Q: How much acoustic panel coverage do I need for a room?
A: The required coverage depends on the room volume, existing finishes, reverberation requirement and target acoustic performance. The quantity should be calculated from the project acoustic requirement rather than panel quantity alone.
Q: What documents should I request from an acoustic panel manufacturer?
A: Request the product datasheet, acoustic test report, fire test report, material specification and installation information applicable to the exact product configuration.
Q: How can I compare acoustic panels from different suppliers?
A: Compare the same panel construction, NRC or αw test method, fire classification, dimensions, weight, installation condition and commercial terms before comparing unit prices.
Q: Why should the acoustic test configuration match the installation method?
A: Sound absorption can change with the backing, air gap and mounting method, so laboratory results should be evaluated against the intended installation configuration.
Q: What information should be included in an acoustic panel RFQ?
A: Include panel dimensions, quantity, acoustic target, fire requirement, color, destination, packaging requirements and required technical documents.
Q: Can acoustic panels be approved using a sample before mass production?
A: Yes. A physical sample allows buyers to verify dimensions, grille appearance, color and surface quality before approving bulk production.
Q: What should be checked before placing a bulk acoustic panel order?
A: Confirm the approved product specification, acoustic and fire documentation, sample, quantity, MOQ, lead time, packaging, payment terms and shipping terms.
