Israeli technology startup Silentium unexpectedly received a $10 million investment from an unidentified Russian investment bank, Forbes reported.
Noise pollution from a wide range of electronic equipment can cause stress, impair hearing and communication, and adversely affect productivity and health. Silentium’s biggest product, the S-Chip microchip, detects and analyzes noise, to predict the sound waves which are about to be produced—split seconds before it takes place—and produces a sound wave of its own, the mirror version of the unwanted noise. When the two sound waves meet, they cancel each other out in a process known as “destructive interference, ” resulting in a 90 percent reduction in unwanted noise.
Dubbed as Silentium’s Active Noise Control, its devices provide users with the capability to allow air to flow undisturbed, while preventing noise.
According to Forbes, Silentium, seeking an expansion of its market base with its S-Chip, has been supported in the past by SMI/Naor, an investment firm based in Toronto, Terra Venture Partners, based in Israel, Blue Coast Private Equity, based in the UK, and Heliant Ventures.
Barath is currently raising a third round of funding.
Ben Weiss, portfolio manager for a Hong Kong venture capital fund that also invested in Silentium, told Forbes: “There are a billion products that are made every year that have a noise problem that in theory could use Silentium.”
One of the major consumers of Silentium’s technology is Faber, which produces noiseless extractor hoods for home kitchen use.
Silentium next intends to apply its technology to create “silent bubbles’ onboard airplanes. A device will be implanted in airline pillows, canceling out the noise emanating from the engines.
Naturally, the device could also be implanted in regular pillows, for people living on busy city streets.
Silentium was founded by Yossi Barath, now its CEO, in 1997. It has closed down and reopened twice since then, most recently in 2005. The company employs 25, and is based in Rehovot, east of Tel Aviv.
Sources within the company are saying they are not rushing to do an early exit before proving themselves—before there are with S-Chips installed in thousands of devices around the world.
