how does active noise cancellation works and is it more harmful to your ears than normal headphones or earphones
In: Technology
There is another way to dampen sound, usually used for loud environments like shooting ranges or industrial environments. The earmuffs you wear are actually passive, meaning that even without the system turned on, they are like normal earmuffs with a high noise reduction rating. However they use microphones to transmit sound to your ear but they limit the maximum amount of sound they allow. So at a shooting range, you can talk normally to people but when a gun shot goes off the sound is either cut off, or the sound is allowed through, but at safe volume.
It’s like watching TV where they just turn the volume down on really loud harmful noises.
Active noise cancellation works better on annoying constant white noise, like airplane engine noise.
