WHY NOISE REDUCTION HEADPHONES ARE POPULARSurrounding noise can be extremely intrusive when you're wanting to hear music on the commute to work or on a plane. When you aren't able to listen to your music , the normal impulse is to turn up the volume level, which isn't healthy for your ears or the sound quality. But if you dont pump up the volume then you are not able to enjoy your music as you would at home, and instead have a long, boring journey to sit through. As a result of this widespread problem for commuters and travellers, there's a large marketplace for sound cancelling headphones which not only block out background noise but also enable you to listen to your music at a sensible level of volume.There are many situations when noise cancelling technology is beneficial. This includes to avoid the noise created by other family members at home, on planes to cancel out jet engine noise and so you dont have to listen to the conversations of fellow commuters. An additional great thing about noise cancelling headphones is that sound cancellation works in two ways. Not only is it a benefit to the owner of the headphones but it also insulates the sound from annoying other people sat in proximity, enabling both the listener and surrounding passengers to enjoy their journey in silence.HOW DO THEY WORK?The headphones have the ability to offset the surrounding sounds due to a compact microphone that gauges the exterior background noise. It gauges the frequency of the encircling noise and then commands the headphones to integrate a polarized pitch which is implemented to cover the background pitch. When a sound frequency is exactly opposite, or polarized, the two sounds clash and cancel each other out, hence noise reducing headphones.CHECK OUT THESE NOISE CANCELLING HEADPHONESAKG K495 Premium Active Noise Cancelling Headphones - Along with Sennheiser, AKG is one of the most respectable headphones brands.
