Noise-cancelling headphones have been around for a, surprisingly, long time. Dr. Amar Bose first came up with the idea for noise-cancelling headphones in 1978, after she realized that was difficult to enjoy listening to music with the roar of the airplane engine going on in the background.
As time has passed, the technology behind noise-cancelling headphones has steadily improved. Nowadays, noise-cancelling headphones can drown out a multitude of different sounds: babies crying, humming, engines, or other everyday noises.
However, not all noise-cancelling headphones are created equal; the ability of each individual pair of headphones to block out sound is specific to each pair. So how does all of this work? Let's take a look.
How do noise-cancelling headphones work?
Noise-cancelling headphones rely on “inverse waves” to block outside noise from entering the headphone. Inside each pair there are multiple processors and different sound technology that effectively produce the waves. A microphone in the headphone takes the outside sound and then sends a signal to the headphone to create a specific frequency wave that then cancels out the incoming sound. This is known as an inverse wave. The microphone picks up the incoming sound pitch and its decibels, sending a signal to the processor to create an inverse wave to cancel it out.
How do I make sure I'm getting the right pair of noise-cancelling headphones?
When you go to buy a pair of noise-cancelling headphones, understand that every pair of headphones is going to only be able to block specific sound waves, not all sound waves. Make sure that the pair that you buy is able to block sound waves that you come into contact with most often; if you're a frequent flyer make sure that the headphones you buy can block engine noise. If you live in a busy city, make sure you buy a pair that can cancel out voices.
