Many of us have turned up the volume on our personal audio players to block out the sounds of airplanes, buses, and loud talking. Turning up the volume is a temporary solution that may lead to permanent damage over time. If you experience ringing in the ears after listening to music, you need to turn down the volume immediately. Otherwise, you may sustain permanent damage to your hearing. Rather than turning up the volume on your personal audio player, try a pair of noise cancelling headphones instead. Regular headphones fit snugly around the ear, and work to block out the sounds of the outside world. Noise cancelling headphones use modern science to detect and avert external sounds. Rather than just blocking out sounds, some headphones actually deter the signal for optimal sound quality and noise diffusion. Noise cancelling headphones feature small microphones to detect the sounds, and external circuitry that turn the sound wave upside down. Through a series of complex steps, ambient noise is cancelled by adding the sonic opposite of the sound to neutralize it. In the end, all that's left in your headphones is the music. When it comes to finding noise cancelling headphones, you have plenty to choose from. Bose Quiet Comfort Two headphones have received rave reviews. These headphones were originally designed for airline travel, and they provide you with a clear and precise sound every time. RCA HPNC100 headphones may even boost audio levels and improve bass sounds. |
