how does active noise cancellation works and is it more harmful to your ears than normal headphones or earphones
In: Technology
Sound travels in waves like the ocean. Now imagine that you have 2 oceans, with one wave pattern, and another ocean with the exact opposite wave pattern. The two waves will cancel each other out, and leave a calm area of ocean. The same with ANC (Active Noise Cancellation.) A mic is listening to outside noises, and then generating the opposite sound wave to cancel out that noise. If you listen to this it just sounds like white noise(static), but as soon as you listen to it with the outside sounds, they’re much quieter which is why alot of ear buds have the technology to isolate outside noise.
There is no harm in ANC as its the exact same as noise you hear everyday, but opposite. I hope that makes sense.
