Modern lives seem full of all sorts of noise, some of which not only corrupt a clean signal and prevents it from being understood, but also are dangerous to our ears. The purpose of the noise cancelling technology is to cancel or at least minimize unwanted sounds.
VOXTECH provides a range of products which try to block the sound at the source instead of trying to prevent the sounds from entering our ear canals.
How does it work? Sounds travel through the air or through liquids in the form of waves, and each of those waves has a particular shape. Noise cancelling technologies first rely on small microphones that detect the sounds in a given environment. A digit signal processor determines what sound wave is required to cancel the unwanted sound wave and then it creates that sound and amplifies it through speakers or headphones. One way to understand this is to imagine a ‘positive' sound and a ‘negative' sound created at virtually the same time, and these two sounds cancel themselves out thereby bringing the listener closer to silence.
