Active noise cancelling systems are used most commonly in cars the nissan bluebird was the first to use it way back in 1992 but it didn t catch on till more recently and high end headphones. Active noice cancellation anc uses sound to minimise other sounds you may be thinking that anc is just a technical term for white noise but actually it is very different as active noise is designed to counteract problem noise causing both noises to effectively cancel each other out so you don t hear anything. Silentium is an innovator in high performance active noise cancellation. Because quick irregular sounds like music sounds and people talking are over with long before your headset can calculate how to cancel them the only noise attenuation your anc headset will offer against annoying coworkers tv noise is simply what sound they can physically block out.

Active noise cancellation anc systems work best on droning sounds that are constant in frequency and intensity. During prototype testing sono s transducer used active noise canceling to successfully lower the audio signal by 12 decibels which would probably do a good job of blocking out quieter sounds in. A noise cancelling system is an active noise control system which listens to the surrounding ambient sounds and plays opposite sound in sync with the problem noise. With superior technological development we are able to cut out up to 90 of a sound no matter if it s an oven hood a ventilation system a car engine or a noisy train.

To achieve 3 db active noise cancelation in say a 20 by 20 by 8 ft room would require a significant number of speakers mounted on the walls and a microphone mounted on the head of the occupant and connected to a computer which would control the wall speakers to generate sound which is out of phase with the noise reaching the occupant.
