S-LEC™ Sound Acoustic Film Sound insulation interlayer film

The loudest sound range is made quietest.

●the sound insulation performance of the film is improved

Features

In humans, most audible sounds range from 1,000 to 4,000Hz. The Sound Acoustic Film improves the sound insulation effect by 5dB compared with standard interlayer films.S-LEC™️ Sound Acoustic Film sound insulation interlayer film is achieved by the three-layer extrusion tech nolog y t hat pr oduces a f il m consisting of a sound insulation layer (core layer) and two layers of standard interlayer film (external layers) that sandwich the core layer. With this technology, the sound insulation performance of the film is improved while it also maintains the basic performance of standard interlayer films.
