How Do Noise Canceling Headphones Work?

The engineering inside noise-canceling headphones is rather intricate. Let’s see how.
Check out for all kinds of PCBs, easy ordering, and quick delivery.
Take a look at their PCB Assembly, for an inexpensive population of the components on your PCBs.

Noise is all around us, so how have engineers designed headphones that eliminate it? Well in this video we explore the physics of active noise-canceling headphones, and how noise can be removed from the environment using technology.
