Silentium Active Noise Cancellation

Posted by Andrew at 12:55 AM on February 8, 2012

Silentium LogoSilence is golden and Silentium are working hard to achieve this with their active noise reduction technology. Andy and Don keep it down with Yossi Barath.

Silentium has developed an active noise reduction system that can be implemented in a single chip. The complex (and proprietary) algorithms programmed into the chip use noise cancellation (destructive interference) to reduce the amount of sound coming from a machine to make it quieter. Ventilation systems, air conditioners, computers and data centers are all examples of where Silentium’s system can be used to reduce the noise.

At CES, Silentium are releasing QB2, a headrest-embedded system which creates a bubble of quiet around a person’s head, perfect  for air travel or similar passenger situations. Generally, Silentium doesn’t produce products but sells its technology to other companies for inclusion in their own.

All sounds intriguing.
