Do you need absolute silence to concentrate on your work, your studies, or even to relax while traveling while watching an episode of one of your favorite series? If so, what you need are noise-cancelling headphones. It may seem ambiguous, but these are the answer to your search for silence.
There are two types of noise cancellation: passive noise cancellation , also known as sound insulation; and active noise cancellation , which allows you to enjoy the highest quality sound while also isolating you from outside noise.
But how does this system work to block out noise and create the silence that is so necessary on many occasions?
How the noise-cancelling system works in headphones
Well, external noise is eliminated by following the theory of wave interference. Sound is a wave that obeys the principle of superposition. This principle states that when two waves meet at a point or region of space, the result is a new wave resulting from the sum of the two original waves.
In the case of active noise cancellation, an artificial inverse wave is created which, when combined with the wave produced by external sound, completely or partially cancels the external sound wave, especially those related to low frequencies. This effect is known as destructive wave interference.
This entire process is carried out through microphones and an audio processor located in devices equipped with ANC technology, which capture, process, and cancel the sound of outside noise so that the person's ear does not receive it.
In turn, most devices that have Active Noise Cancelling technology have the ability to deactivate noise cancellation when it is not necessary, thus saving the device's battery.
Active noise-cancelling headphones by Energy Sistem
Energy Sistem offers several devices that feature this active noise cancellation technology. These models adapt to each user's preferences to offer comfort, quality, and design in equal measure.
The BT Travel 6 ANC Black Headphones are an ideal device to take with you on your travels, as they reduce outside noise from everything around you, allowing you to enjoy pure sound.

The Moon True Wireless Travel 6 ANC Earphones will immerse you in your music and make you forget what's going on around you. This model also features Transparency Mode, which allows outside sounds to be captured while the earphones are in use. This is a very useful feature, especially in busy urban environments, allowing you to stay connected while listening to music.
Recommendations for using audio devices with ANC technology
This system only adds positive aspects to the audio devices that have it.
Among them, this noise-cancelling headphone feature will be very useful mainly for low-frequency waves, such as the noise of trains, airplanes, and engines, where this noise will be significantly reduced.
If your study or work environment is quiet and doesn't interfere with your listening experience, there's no need to activate this feature, as its effect won't be noticeable, and your battery will last longer with your headphones performing optimally.
For this reason and much more, headphones that include this technology are presented as a clear purchase option that will make you, once you try them, not want to have headphones without it.
