The rush hour traffic noise makes it difficult to hear music on your mp3 player while traveling. To counter that, most of the times, you pump up the volume to a point where its playing at a maximum. In doing so, you may permanently damage your ears with prolonged exposure to loud noise. Besides, surrounding or ambient noise also ruins your listening experience—a problem faced by frequent air travelers. Enter the new breed of noise cancellation headphones which block out the ambient noise thereby enhancing your listening experience. There are two types of noise cancellation—Passive and Active. Passive noise cancellation is basically achieved by using headphones that cover your ears or in-ear earphones that plug into your ear canal thereby blocking the outside noise. Active noise cancellation is a little complex. There is a tiny microphone on each headphone that senses outside noise before it enters your ear. Then the noise cancellation circuitry inverts the captured signal and feeds it to whatever your are listening to, thereby canceling most of the ambient noise. And while discussing this new technology, we are looking at Bose’s latest revision of their Noise Cancellation Headphones—the Quiet Comfort 3. The Quiet Comfort 3 comes with passive noise cancellation and also boasts of active noise cancellation. We review the headphones to see how well it copes up. |
