Premium Acoustic
Foam Panel Systems
Acoustic wall panels are designed to absorb sound, not block it. While barriers such as noise walls or mass loaded vinyl (MLV) stop noise from passing between spaces, wall panels reduce the sound energy reflected from the walls.
By absorbing reflections off hard surfaces, panels reduce reverberation time, improve speech intelligibility, and create a more comfortable acoustic environment.
Acoustic panels are essential for spaces where clear communication and reduced ambient noise are critical, including offices, classrooms, manufacturing floors, healthcare facilities, and hospitality venues.
At Memtech, our panels are engineered with high-performance materials and tested to deliver highly effective sound absorption with an NRC rating up to 1.05. Whether you need to control echo in a large auditorium or improve focus in an open office, our wall panels offer performance with architectural-grade aesthetics.

Acoustic WALL Systems
Kinetics® IsoMax™ Sound Isolation Clips
IsoMax™ sound isolation clips hold drywall furring channel off the stud or joist, decoupling the gypsum board from the framing in walls and ceilings.
The clip surrounds the channel, so an installer cannot screw through a resilient leg into the framing, a common way resilient channel loses its isolation in the field.
Every rating below applies to a complete tested assembly, so the full wall or ceiling build-up needs to match the tested design.

Frequently Asked Questions (FAQs)
How do acoustic wall panels reduce echo in a room?
Acoustic wall panels reduce echo and reverberation by absorbing sound reflections that bounce off hard surfaces such as drywall, glass, and concrete. The acoustic core material converts sound energy into heat, reducing reflected noise and improving speech clarity.
What is the best way to reduce echo on walls?
The most effective way to reduce echo on walls is to install acoustic wall panels or fabric-wrapped sound absorbing panels. These panels absorb mid- and high-frequency sound reflections that cause echo in offices, classrooms, restaurants, and other interior spaces.
Do acoustic wall panels block sound from leaving a room?
Acoustic wall panels are designed primarily to absorb sound inside a room, not block transmission between rooms. To soundproof a wall, additional barrier materials such as mass-loaded vinyl (MLV) or upgraded assemblies like QuietRock constrained-layer damping gypsum board are required.
What materials are used in acoustic wall panels?
Acoustic wall panels use open-cell melamine foam (WILLTEC), recycled polyester (PET) fiber, 100% recycled glass (PHONSTOP), and acoustic plaster systems (SONEX AFS). NRC ratings range from 0.60 to 1.10 depending on the product and thickness.
Can acoustic wall panels be decorative?
Yes. Products like PET felt panels, SONEX AFS acoustic plaster, and WILLTEC flat sheets are available in custom sizes, colors, shapes, and geometric layouts that complement interior design while improving room acoustics.
How do you reduce echo in a conference room?
Echo in conference rooms is caused by sound reflecting off hard surfaces such as glass, drywall, and tables. Installing acoustic wall panels absorbs these reflections, reducing reverberation and improving speech clarity for meetings and video calls.
How do you reduce noise in an open office?
Open office noise can be reduced by installing sound absorbing wall panels, ceiling treatments, and acoustic partitions. Wall-mounted acoustic panels absorb conversations and background noise, improving focus and productivity.
Why do restaurants have so much echo?
Restaurants have hard surfaces like tile floors, glass windows, and exposed ceilings that reflect sound. Acoustic wall panels absorb these reflections and reduce the loud echoing environment that makes conversations difficult.
What is the best acoustic treatment for classrooms?
Classrooms benefit from acoustic wall panels that reduce reverberation and improve speech intelligibility. Absorbing sound reflections helps students hear instructors more clearly and reduces overall noise levels in the room.
How do you improve acoustics in a large room?
Improving acoustics in large rooms requires a combination of acoustic wall panels and ceiling treatments. Wall systems absorb reflected sound along vertical surfaces, controlling reverberation and improving overall sound clarity.
