Noise cancellation is a method to lessen or remove
unwanted sound completely. Scientists believe that with advances
in engineering and technology, unwanted sound can be cancelled
completely and silence can be achieved at the press of a button.
Sound nullifiers used at work will help in cancelling all
noise and creating a quiet zone. It is an active method of
cancellation as the noise is nullified in real time.
Noise cancellation technology is a good solution to the noise
problem of today. Ear-plugs and sound dampeners are can be
used but they not very efficient and uncomfortable. Noise
cancellation works on the sound generated at the origin of
the sound and not after transmission and does not use preventive
methods to block sound waves from being received at the ear.
In simple terms, noise cancellation works by cancelling the
postive sound be a negative sound and creating silence.
This technologies is still new and hope is that one day that
this will reduce noise to a large extent.
