The S-Barrier™ Panel
• Components:
• 2 PZTs (sensor + actuator)
• S-Chip™ microcontroller
• Panel: Aramid Honeycomb core with Epoxy Glass Fiber skin
• Thickness: 6 mm
• Weight: 2.3 Kg/m2
• Fire: Fire-resistant and self extinguishing.
• Service Temperature: -20o-90o C
The S-Barrier is aiming at reducing 10 dB(A) structure borne
noise on top of the passive reduction.
