Posted by admin under Uncategorized on January 21st, 2008.What the noise cancelling headphones are alike? There are same as all basic headphones but have more specific function : for noise canceling.
The noise cancelling headphones itself consist of two kinds : active and passive. The active type uses electronic circuit to sense the incoming sounds to lower the amount you hear. The Passive type no needs power supply to operated.
Then, when we need the noise cancelling headphones instead of the basically ones ? There are at least three conditions below :
1. Use while we are travel by plane. The background sound will reduced by active circuit if we keep the sound volume lower.
2. Use when are on seminars or trainings.
