(Wireless-NewsWire.Com, February 04, 2014 ) Los Angeles, CA -- There are literally hundreds of headphones available today ranging from wired to wireless to in-ear to around-the-ear to Bluetooth to noise cancelling headphones. The latter category is divided to active noise cancelling and passive noise cancelling headphones. Passive ones achieve noise cancellation by physically blocking out external noises entering the headphones and preventing the music from leaking out. The ear cushions are made of certain material that absorbs sound and it's also tailored to fit snugly over the ears to minimize leakage of sound waves. In contrast, active noise cancelling headphones have specific machinery or circuitry that takes care of external noises. These achieve noise cancellation by producing a wave that is exactly opposite to the external noise. The ear cups of these headphones have special mics to listen to the noise and then internal circuitry to produce the opposite notes so that the intruding noise can be cancelled out. It's pretty amazing that such technology exists considering that the reverse signal has to be produced almost at the same time it's 'heard' by its microphone system.
Noise cancellation is mainly important for those who are air-traveling. The noise made by the aircraft engines is often heard 'loud and clear' inside the passenger cabins. This not-so-pleasant noise can interfere with the music one is listening. This is where the noise canceling technology comes in handy to cancel out the noises made by the engines. In fact, modern noise blocking earphones can generate a counter-current signal against many different types of external noises like those heard in subways, streets of New York etc. etc. Even though noise cancellation isn't 100% efficient, a fair bit of noise is blocked out that the difference is like black and white with the most popular brands available.
