Wouldnt it be nice if you could just shut off those sounds that can be so irritating? Those rattles, hums and hissing noises can be extremely annoying, especially when you are trying to focus on something else. Well it appears that a solution has finally presented itself in the form of noise cancelling headphones.
In fact noise cancelling headphones have been in existence for some time, although high research and development costs have previously kept them out of the hand of consumers, until now that is.
Big brand names like Bose and Sony have jumped at the chance to bring noise cancelling headphone onto the consumer market, with a range of reasonably priced products. Some consumers might see the headphones as a little bulky but they certainly outperform their smaller counterparts and reward the listener with clearer sound and more importantly, clearer sound at lower volume levels.
The importance of being able to listen to music clearly at low volume levels has been highlighted by the advent of the iPod, which has taken the music world by storm. According to [http://www.cancelingnoise.com] an iPod is capable of producing somewhere in the vicinity of 85dB of sound, which if listened to for long periods is likely to cause permanent hearing loss. With noise cancelling headphones however, listeners are able to listen to their favorite tracks without competing with ambient noise by boosting the volume to dangerous levels. This makes noise cancelling headphones a must have accessory for anyone who listens to music regularly and particularly those who listen to music while commuting.
Aside from the obvious draw back of being a little bulky, the headsets do use more power than regular headphones. Once again, I would say that the increase in quality and ability to listen to music at lower volumes outweighs this negative. Although noise cancelling headphones are very effective they do have their limitations and short sharp sound is one of them. The headphones are unable to adjust to short sharp sounds, rather they are suited to humming or hissing sounds.
Otherwise they are fast becoming an essential part of audio equipment and a sure fire success as a gift for anyone with an iPod.
