Noise-cancelling headphones are a type of headphones that use active noise control technology to reduce or cancel out external noise. They work by using microphones to pick up external noise and then producing an opposite sound wave to cancel out the noise.
This technology can be especially useful in noisy environments, such as on a plane or in a crowded office, as it can help to reduce background noise and make it easier to concentrate or relax.
Noise-cancelling headphones are available in a variety of styles and price points, from over-ear headphones to earbuds, and can be wired or wireless. It’s important to note that while noise-cancelling headphones can be effective at reducing certain types of noise, they may not completely eliminate all sounds.
The concept of noise-cancelling headphones
Wind some copper wire around a rubbery soft diaphragm that can come back to its original shape when deformed. Connect the wire to a signal conditioner or better known as an amplifier. Put that all in an ergonomic ABS plastic enclosure. Slap a piece of memory foam on top. And there you have it, a thing which almost sounds like heaven but not exactly that. But why? What’s missing? To answer that we will have to take help from the mathematicians and jump back to the late 1700s.
Signal Conditioning:
It is the working witchcraft behind all of the noise-cancellation technology in the world. And mathematicians have a term for it that they are crazy about. It is called Fourier Transformation and we’ll do our best to put it in the simplest way possible. To form an image on your retina, the lens in your eye performs Fourier Transformations on the light that enters it. It is nature’s way of analyzing data, and in the context of hearing by ears, analyzing the sound signals.
We know that sound is noisy, and when you record an instrument you have to capture it electrically. That will involve digitizing a signal, and when you digitize a signal, the noises get amplified. You know what it sounds like when you listen to an old audio track! But you don’t get the noise now. All thanks to Fourier Transformation! It is an algorithm which extracts the different sound signatures from a recorded audio signal.
With time, as the concept of algorithms matured, noise cancellation technology matured too. It went from removing the white noise to the complete removal of background noise, no matter if it is from an aeroplane, a jet engine, or your neighbour’s dog. Time has served us with a highly sophisticated piece of engineering- wireless headphones and active noise cancellation.
Benefits of noise-cancelling headphones
With noise-cancelling headphones, you can enjoy great audio quality as you won’t have to turn up the volume to drown out external noise. This can reduce distortion and improve the overall listening experience. Excessive noise can cause stress and fatigue, especially in work environments. By blocking out ambient sounds, noise-cancelling headphones can help reduce stress and fatigue and promote better concentration.
If you work in a noisy environment, noise-cancelling headphones can help you focus on your work and increase your productivity by reducing distractions. If you have trouble sleeping in a noisy environment, noise-cancelling headphones can help you get a better night’s sleep by blocking out ambient sounds. High levels of noise exposure over time can cause hearing damage. With noise-cancelling headphones, you can reduce the amount of noise exposure and protect your hearing.
So put them on, and enjoy because all it takes to get lost in your own world is not a lot of math, time, complex algorithms and history, but a press of a button on your favourite headphones. We have prepared a list of our favourite choices for every budget range of noise-cancelling headphones:
