Available in various finishes, materials and panel configurations to suit modern interiors.Durability and Stability
Engineered construction ensures long-term performance with minimal maintenance.
Micro perforated panels are ideal for spaces that require both high acoustic performance and premium aesthetics.
Corporate Offices
Boardrooms, meeting rooms and executive spaces where clean design and clear communication are essential.Auditoriums and Lecture Halls
Spaces that require controlled acoustics without visually heavy panel designs.Hospitality Spaces
Hotels, lounges and premium restaurants where subtle acoustic treatment is preferred.Residential Interiors
High-end home theaters and living spaces for discreet sound control.Studios and Performance Spaces
Recording environments where precise sound absorption is required without altering design aesthetics.
Proper installation is important to ensure optimal acoustic performance.
1. Surface Preparation
Ensure the wall or ceiling is clean, dry and level before installation.
2. Framework Setup
Install a support structure using metal channels or wooden battens at standard spacing.
3. Air Cavity Planning
Maintain an air gap behind the panel, as micro perforated panels rely heavily on cavity depth for performance.
4. Panel Fixing
Mount panels using concealed fixing systems or screws, ensuring precise alignment.
5. Joint and Edge Finishing
Achieve a seamless finish with minimal visible joints, often using precise edge detailing.
6. Final Inspection
Check alignment, surface finish and secure fixing.
For best results, the depth of the air cavity and panel configuration should be carefully designed to match the required acoustic performance.
Acoustic Performance
Micro perforated acoustic panels deliver advanced sound absorption through precisely engineered micro holes, typically less than 1 mm in diameter. Unlike conventional perforated panels, they work on the principle of sound wave friction and resonance within the micro perforations, allowing effective absorption without large visible openings.
The acoustic performance of these panels is measured using the Noise Reduction Coefficient (NRC), which generally ranges from 0.70 to 0.95, depending on panel design, cavity depth and installation method. Their performance can be finely tuned by adjusting parameters such as perforation size, spacing and the air gap behind the panel.
These panels are particularly effective across mid to high frequencies, making them ideal for speech clarity and noise control. When combined with a properly designed air cavity or additional acoustic backing, they can also achieve enhanced low-frequency absorption, creating a well-balanced acoustic environment.
Key factors influencing performance include:
Micro Perforation Size and Density
Smaller and precisely distributed holes control how sound energy is absorbed through friction and resonance.Air Cavity Depth
The gap behind the panel plays a critical role in determining low-frequency absorption.Panel Thickness and Material
Denser and thicker panels improve overall acoustic stability and performance.Installation Accuracy
Proper sealing, alignment and fixing ensure there are no gaps that reduce effectiveness.Optional Backing Material
While not always required, adding acoustic infill can further enhance absorption in certain applications.
By reducing reverberation and controlling sound reflections, micro perforated panels create a clean and acoustically balanced space without compromising on design. They are especially suitable for premium interiors where both sound quality and seamless aesthetics are essential.
Customization Options
Micro perforated acoustic panels offer a high level of customization, allowing precise control over both acoustic performance and visual appearance. Their design flexibility makes them suitable for premium interiors where subtle detailing and performance are equally important.
Perforation Design and Density
The size, spacing and density of micro perforations can be customized to achieve the desired acoustic response. Smaller holes with higher density provide more controlled absorption while maintaining a clean surface appearance.
Open Area Ratio
The percentage of perforated surface can be adjusted to fine-tune sound absorption. Lower open area maintains a more solid look, while higher ratios improve acoustic performance.
Material Selection
Panels can be manufactured using MDF, HDF, plywood, metal or composite materials based on application requirements. Fire-retardant and moisture-resistant variants are also available.
Surface Finishes
A wide range of finishes can be applied, including natural wood veneer, laminate, melamine, paint or powder coating. This allows seamless integration with modern and high-end interior designs.
Panel Size and Thickness
Custom panel dimensions and thicknesses can be specified to match wall or ceiling layouts, ensuring efficient installation and minimal wastage.
Cavity Depth and Acoustic Design
The depth of the air gap behind the panel can be customized to target specific frequency ranges, especially for improved low-frequency absorption.
Edge Detailing and Joint Design
Panels can be designed with precise edge profiles for nearly invisible joints, creating a smooth and continuous surface finish.
Color and Design Integration
Custom colors and finishes allow panels to blend into interiors or stand out as a design feature, depending on the project requirement.
This level of customization enables micro perforated panels to meet strict acoustic targets while maintaining a refined, minimal and high-quality architectural finish.
Micro Perforated Acoustic Panels FAQs
What are micro perforated acoustic panels?
How do micro perforated panels work?
They absorb sound through micro perforations that create friction and resonance as sound waves pass through, reducing reflection and improving acoustic clarity.
What is the NRC of micro perforated panels?
The NRC typically ranges from 0.70 to 0.95, depending on perforation design, panel thickness, cavity depth and installation method.
Do micro perforated panels require acoustic backing?
In many cases, they can perform effectively without visible backing. However, adding acoustic infill or an air gap can enhance performance, especially at lower frequencies.
Are micro perforated panels better than perforated panels?
Micro perforated panels offer a more seamless and premium look with nearly invisible holes, while still providing strong acoustic performance. The choice depends on design preference and project requirements.
