PackSound Perforated Acoustic Panels
PackSound EchoStop™ Perforated Acoustic Panels are expertly engineered to enhance acoustic comfort while complementing interior design. Designed for high-performance sound absorption, these panels feature a precision-perforated surface that allows sound to pass through and be absorbed by an internal acoustic layer, effectively reducing echo, noise, and reverberation. Made with fire-rated MDF or HDF cores and optional acoustic fleece or mineral wool backing, EchoStop™ panels offer a safe, functional, and visually refined solution. Customisable perforation patterns ensure tailored acoustic performance without sacrificing aesthetics.

Perforated acoustic panels are versatile and suitable for multiple environments.
Commercial Spaces
Offices, conference rooms and boardrooms where clear communication is essential.Institutional Buildings
Auditoriums, lecture halls, classrooms and libraries requiring controlled acoustics.Hospitality and Public Areas
Hotels, restaurants and lobbies where noise control enhances user experience.Residential Interiors
Home theaters and living areas for improved sound comfort.Specialized Spaces
Recording studios, cinemas and performance areas where sound quality is critical.
Correct installation is important to achieve the intended acoustic performance.
1. Surface Preparation
Ensure the installation surface is clean, dry and level before starting.
2. Framework Setup
Install a support framework using metal channels or wooden battens at regular spacing (typically 500–600 mm).
3. Acoustic Backing Placement
Fix mineral wool or polyester fiber behind the panels to enhance absorption.
4. Panel Installation
Mount panels using screws or concealed fixing systems. Ensure proper alignment and spacing.
5. Joint and Edge Finishing
Seal joints neatly and use trims or edge profiles for a clean finish.
6. Final Inspection
Check for alignment, secure fixing and surface cleanliness.
For improved acoustic performance, maintaining an air gap behind the panel helps enhance low-frequency absorption.
Acoustic Performance
Perforated acoustic panels are designed to provide controlled sound absorption by allowing sound waves to pass through the perforations into an absorptive backing layer. This combination of a rigid front surface and porous backing helps reduce reflected sound, resulting in improved acoustic clarity within a space.
The performance of these panels is typically measured using the Noise Reduction Coefficient (NRC). Perforated panels generally achieve an NRC between 0.65 and 0.95, depending on the perforation pattern, open area ratio, backing material and installation method.
These panels are effective across a broad frequency range, particularly in mid frequencies such as speech. With the addition of high-density mineral wool or polyester backing and an air cavity behind the panel, their performance can extend to low frequencies, helping create a more balanced acoustic environment.
Key factors influencing acoustic performance include:
Perforation Size and Pattern
Larger holes and higher open area ratios allow more sound energy to pass through, increasing absorption.Open Area Ratio
The percentage of perforated surface directly impacts how much sound is absorbed versus reflected.Backing Material
Dense acoustic infill materials significantly enhance sound absorption efficiency.Air Gap Behind Panel
A cavity between the panel and the wall improves low-frequency performance.Panel Thickness and Density
Thicker and denser panels help in controlling sound transmission and improving overall performance.
By reducing reverberation time and controlling unwanted reflections, perforated acoustic panels create a more comfortable and intelligible sound environment. They are especially effective in spaces such as offices, auditoriums and conference rooms where clear communication and acoustic balance are essential.
Customization Options
Perforated acoustic panels offer extensive customization, allowing designers to achieve the right balance between acoustic performance and visual design. From perforation patterns to finishes and panel configurations, these panels can be tailored to meet specific project requirements.
Perforation Patterns and Hole Sizes
Panels can be customized with different hole diameters such as 6 mm, 8 mm or 10 mm, along with various layouts like square, staggered or random patterns. The choice of perforation directly impacts both the visual texture and acoustic absorption.
Open Area Ratio
The percentage of perforated surface can be adjusted to control how much sound is absorbed. Higher open area improves absorption, while lower ratios maintain a more solid visual appearance.
Material Selection
Core materials such as MDF, HDF, plywood or gypsum boards can be selected based on durability, cost and application needs. Moisture-resistant and fire-retardant options are also available.
Surface Finishes
Panels can be finished with natural wood veneers, laminates, melamine coatings or custom paint finishes. This allows seamless integration with different interior themes, from modern to traditional.
Panel Sizes and Thickness
Custom dimensions and thicknesses can be manufactured to suit specific wall or ceiling layouts, reducing wastage and ensuring a precise fit.
Acoustic Backing Options
Different types and densities of backing materials, such as mineral wool or polyester fiber, can be used to achieve the desired NRC levels. Additional air gaps can also be incorporated for enhanced performance.
Edge Detailing and Joint Design
Panels can include various edge profiles for seamless joints or visible design lines. This helps achieve either a continuous surface or a patterned layout.
Color and Branding Flexibility
Custom colors, textures and even branding elements can be incorporated, especially in commercial and corporate spaces.
This level of customization makes perforated acoustic panels suitable for both standard installations and highly specialized acoustic projects, ensuring they meet both functional and design expectations.
Perforated Acoustic Panels FAQ
Perforated acoustic panels are used to reduce echo, control noise and improve sound clarity in spaces such as offices, auditoriums, conference rooms and studios.
The perforations on the surface allow sound waves to pass through the panel and get absorbed by the backing material, reducing sound reflection and reverberation.
The NRC typically ranges from 0.65 to 0.95, depending on the perforation pattern, backing material and installation method.
Both have similar acoustic functions, but perforated panels offer more uniform absorption across frequencies, while grooved panels provide a more linear design aesthetic.
