TYPE L provides a targeted acoustic solution for spaces that require a balance between design and performance.
It is particularly suited to architectural projects that need reverberation control without weighing down the structure or detracting from the look of the space.
Technical description
The TYPE L panel is based on patented Stillness technology and acts as a sound-absorbing element (absorber) with a multi-layer structure optimised for absorbing sound waves.
The outer layer is designed to be acoustically transparent, allowing sound waves to pass into the panel core, where damping takes place and sound energy is converted into heat.
The panel core is made of a sound-absorbing material with a porous/foamed structure that provides airflow resistivity – a key parameter in the absorption of mid and high frequencies.
The panel works by combining the following mechanisms:
- Absorption
- Partial diffusion
- Reduction of direct sound reflections
In this way it improves the decay time (RT60), reduces flutter echo and improves the uniformity of the sound field in the space.
Applications
- Architectural spaces – offices, halls, public buildings
- Studios, recording rooms and podcast rooms
- Industry – factories, machine rooms
- Infrastructure – railway stations, tunnels, technical facilities
- Acoustic wall and ceiling cladding
- Outdoor acoustic solutions
- Public buildings
