The “Pain”

• Equipment/Products generate Noise

• Noise is Pollution, annoying, harmful and

reduces productivity and “Quality of Life”

• Noisy products are inferior

• Regulations

• Market demand

Noise Sources-Spectrum

Air flow spectrum example

Active Noise Control => effective in the low frequency band

Passive absorption => effective in the high frequency band

Broad band Noise => Requires a combination of

Passive and Active Noise Control

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.
