Branch Education | How Do Noise Canceling Headphones Work? @BranchEducation | Uploaded 3 years ago | Updated 3 hours ago
The engineering inside noise-canceling headphones is rather intricate. Let's see how.
Check out https://www.pcbway.com/ 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.

Have you ever wondered what it would be like to journey through the inside of your computer? In this video, were taking you on a 3D animated adventure to every piece of computer hardware inside a desktop computer. Youll also see a nanoscopic view of the transistors inside the CPU and GPU. This video is like a biology dissection lab; instead, were opening up a computer and seeing all the various computer hardware inside.
