It will pick up problem background noises such as traffic, music, people talking and relay them back to the headphones. Headphones which use active noise cancellation utilise a small microphone on the outside of the headphone piece to listen to the ambient noise in the background.

What Is Active Noise Cancellation?Īctive 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.Īctive Noise Cancellation is a technology which is used in some high-end headphones, it is also used in some high end computer fans as these can be notoriously noisy in high powered machines (before you are tempted to buy one read our article on how to fix a loud laptop fan - it could save you a good wedge of cash!).ĪNC is also commonly known as Active Noise Reduction (ANR) and Active Noise Control technology. Instead of passively doing nothing other than blocking the sound Active Noise Cancellation is a method in which sound is actively created to cancel out any problem noise. This is called passive noise reduction it involves insulating a room or your ears against sound and is the typical method employed for most soundproofing projects.Īctive Noise Cancellation is very different. Usually when we encounter a noise problem in our life the first thing we do is seek to block it out.
