How things work: active noise-cancelling headphones | What Hi-Fi?

Noise headphones were invented for long-haul aircraft pilots and have become an important part of everyday life for some people. In this informative article today, we will see that how do noise cancelling earbuds work. 

Other than my wallet and my travel card, there’s something I wouldn’t be in a big city without, and these are my headphones. But I don’t really listen to that much music: I enable the noise cancellation feature and leave it that way.

No sound comes to my ears – instead of a silence filling my head, it is as if the voices of the world have been rejected. Until I got the noisy headphones, I had no idea how loud this city was and how hungry I was for silence.

On public transport, the use of noise cancellation feature will soften the roar of engines and traffic. In an open-plan office, this removes permanent nonsense and limits barriers. On the plane, this is a revelation. I’m not alone using sophisticated headphones, not for music, but to find a permanent drone for urban life. It is becoming a means of survival for modern life.

Matt Thomas, a dynamic and dynamic graphics designer in London, is a religionist. He discovered that he could accidentally use the one-day silence feature on his own when his music played on the tube: “I thought, wait a minute, it’s really nice and calm. It was like the moment when the sound disappears in a movie and everything moves slowly.

Heavy traffic produces noise up to 85 decibels (dB), which the Health and Safety Executive believes is enough to cause permanent hearing loss if we live in front of it for several hours a day. Underground trains can charge 100 dB when roaring in a strong corner.

Thomas often keeps his headphones silent on public transport (he doesn’t do that on the streets after running around), but prefers music for work. For Johanna Vogel, an economist in Vienna, Austria, the opposite is true: she plays music on the bus but works quietly. Vogel has bought his noisy headphones hoping that they will help him get his attention in an open plan plant office. “It’s very comfortable,” she says. “I used to doubt it would make a big difference, but now I can’t live without them. In a noisy environment, I really need some way to create silence for myself. If you like bass rich sound then you need to check soundbar.

The noise only damages our ears. Research studies have found a link between long-term noise exposure and an increased risk of heart attack and stroke, as well as low mood and difficulty sleeping and concentrating. Harmful effects on mental and physical health can start at just 65 dB, a level that looks moderate: a refrigerator constantly humming at 40dB, and an open plan office resonates at about 60dB.
