Utilizing a built-in microphone, noise-canceling headphones measure ambient sound, and then generate a waveform through the ear piece that is the exact negative of this ambient sou...
How do headphones cancel outside noise? Your headphones cancel ambient noise by using a trick called “phase inversion” to create “anti-noise.” The concept is simple, but it’s tricky to get right. If you were to take two identical waves and line them up with each other, matching up...
