active noise control, reinvented.

Active noise control (ANC), also known as noise cancellation, or active noise reduction (ANR), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first.”

Cancelling noise with opposing sound waves is an old concept ..

The concept of eliminating noise with its negative equivalent goes as far back as June 1936, when Paul Lueg filed his patent on “silencing sound oscillations”. Yet it has never found widespread application, apart from noise-cancelling headphones.

We believe this is rooted in mainly three reasons:

  1. The concept seems easy, but becomes extremely complex to solve in open-space. This requires affordable processing power which has not been available until recently.
  2. Real-life applications require reliable implementation of such technology. Several attempts to date have failed either due to ignorance of basic physics at play or proper product engineering.
  3. Active noise & vibration control is by no means a solve-it-all solution to any type of noise. Rather think of it as the secret sauce that can only unfold in combination with insulation. Picture noise cancelling headphones, that already shield lots of noise without the electronics running. But pushing that button brings the secret sauce to life, just making that small but relevant difference.

Yet, much of its potential only becomes possible today.

Rocket Science GmbH has leveraged these lessons and developed a state-of-the-art active noise & vibration control technology. This technology is driven by a suite of real-time algorithms available for almost any type of application. Our algorithms typically outperform anything else on the market in terms of performance and cost.

We deliver significant broadband performance including lots of random noise up to about 4’000 Hertz, opening up many new areas of application. Our main design criteria is to keep a small footprint for implementation on commodity hardware, potentially reducing per unit cost for any of our customers.

With all these words though, we can’t do our technology justice. You have to listen to it working in real-time to appreciate the difference. Are you ready for this?
