Acoustic sound walls, Noise transmission barrier walls and Lamaphon
Acoustic sound walls
Acoustic sound walls and Lamaphon known as THX walls and Acoustic baffle walls are used with high-performance sound systems in multiplex cinemas, sound studios and foley rooms. These acoustic walls are used to mitigate any reverberation, interference or noise pollution from behind the projection screen with perforations.
Acoustic sound walls are used in conjunction with cinema stage speakers. By physically surrounding the speakers, it minimises any sound that may be bouncing around in the void preventing it leaking out, projecting a cleaner crisper sound.
The Build
Sound walls are built using timber, plasterboard and Lamaphon sheets. Lamaphon stops reverberation behind the cinema projection screen and the sound wall. We recommend a one-meter void behind acoustic sound walls so future engineers and technicians can work on the speakers, masking systems or other equipment without damaging your acoustic walls.
To complete the installation of these walls, we install your cinema projection screen onto the acoustic wall and place any motors, masking systems and noisy apparatus behind the wall, in the void to avoid any amplified noise or noise pollution in the auditorium. Your equipment is in safe hands, we mount your speakers onto speaker platforms which we make as part of the sound wall. The speakers will fit flush with the Lamaphon. We want to ensure your customers have the very best experience in your venue which is why we strategically place your speakers behind the surface around 50mm away to allow the sound to project through the cinema projection screen surface and direct it to be exactly where it’s needed. A crisp, clean sound, the perfect cinema experience.
Noise transmission barrier walls
Noise transmission barrier walls (NTBW) are used to stop sound traveling through the wall. Commonly referred to as soundproofing, these barrier walls are perfect for many applications, for example these systems can be installed in a boardroom where privacy is key, they stop noise penetrating through walls.
Noise transmission barrier walls are constructed on existing walls, so no structural building work is required. These are a simpler and more robust way to soundproof your space. To create these barrier walls we use timber, Class ‘O’ high mass acoustic foam, acoustic plasterboard and resilient channel. To ensure quality soundproofing we ensure to leave an air gap between the plasterboard and acoustic foam. To ensure a quality finish, we install our ClothGrip Softwall Treatment pattresses for your plug sockets, TV’s, speakers and any wall fixtures. Once everything is in position we install the cloth onto the barrier walls and all your fixtures now fit perfectly into the new soundproofed area.

Next, we install our ClothGrip Softwall Treatment, but before we cloth we add pattresses for your plug sockets, TV’s, speakers, and any wall fixtures. To finish the barrier walls, we install the cloth onto ClothGrip Extrusion over the pattresses so the fixtures sit flush on top of the fabric, giving a professional clean finish.
Lamaphon
Lamaphon is a tissue faced dense mineral fibre with a Class ‘O' fire-rating. Lamaphon is used in most mainstream cinemas, multiplex venues and screening rooms where sound has to be of the best possible quality but is not totally essential to the working environment for example like it would be in a sound studio. Fitted to the rear of the projection screen wall, Lamaphon stops sound bouncing behind the back of the stage wall and screen surface. This pushes a crisper sound forward into the auditorium, improving the sound quality for the audience.
