Have you ever been the victim of suffering unwanted noise
whether it be in the home or your work environment?
The answer is in a set of headphones that are specifically
made to cancel out the offending sound.
They work by producing an ‘anti-noise’ device in the
headset. Simply speaking, if a noise is made with the
opposite polarity of the offending noise then it cancels it
out!
This means that music can be listened to at a lower volume
or indeed the intrepid air traveler can sleep on a noisy
aircraft.
The anti-noise system was created, not for the home user,
but for the workers who are around aircraft or heavy
machinery. It was applied to headsets for long haul pilots
and eventually for home users.
Some airlines offer the sound canceling headphones in their
first-class sections. The ‘anti-noise’ can even be played
back through the headrests making a far more peaceful
environment for traveling long distances.
The continuous hum of aircraft engines can be rather
disconcerting on long flights.
However, if you really want to cut out background noise
while you concentrate on the music or perhaps that seminar
recording, this type of headphone will be beneficial.
It appears that you only get what you pay for. Some of
these headsets can be bought for under $100 but the sound
canceling qualities are not as good as the high end
headphones.
Here you can pay upwards of $300 – $400. A high price to
pay for a little peace and quiet!
