Hear What You Want
Each day, we work our way through
this crazy world as victims of sound. We listen to the noise of
our co-workers, the office fax machine, the car, our families (especially
our mothers), cell phones users that talk too loud and people on
the streets, all without a choice. Now, imagine a world free of
these sounds, free of beeping or honking, free of the loud plane
engine that roars during take off and free of all that other static
noise that drives us crazy. Well, maybe we can’t get rid of
all the noises that make us want crawl into a deep dark hole, but
at least we now have a choice. And that choice is noise canceling
headphones. With these headphones on, you will be a sound victim
no more, all those noises will fade into dust, and freedom of hearing
will reign.
Noise canceling headphones that reduce
unwanted sounds by means of active noise control are one of the
hottest gifts for the 2006 Holiday season. They involve using a
microphone placed near the ear that has electronic circuitry, which
generates an anti-noise sound wave of the opposite polarity of the
sound wave arriving at the microphone. This results in destructive
interference, which ultimately cancels out the noise within the
headphones. The biggest benefit in using noise cancellation headphones
is that you can enjoy your music without having to raise the volume
unnecessarily high. You also might be able to catch some sleep during
a noisy plane or bus ride.
Repeated exposure to high volumes
will absolutely reduce your hearing ability. This is why, in the
age of the MP3 player, it is not a smart idea to turn your audio
device’s volume up to the maximum just to block out your mother
when she asks you to set the dinner table, (otherwise known as “external”
noise.) Noise canceling headphones allow you to blockout the sound
of buses, airplanes and other sources of aggravation while still
enabling you to hear every note of your personal soundtrack without
blowing out your eardrums.
The idea of noise cancellation has
been around for quiet a few years, yet it has been in the form of
passive noise reduction, such as ear plugs, which is nothing more
than the dampening of sounds. This holiday season, active noise
cancellation technology, involving the complex science of detecting
an annoying low-frequency sound and producing an opposite sound
wave, has arrived. Most testing has suggested that noise cancellation
headphones reduce up to 80% of low-frequency sounds. The hardest
noises to block out are also some of the most common, such as crying
and talking, so some headsets also come with passive noise canceling
properties or modes that, when combined with listening to music,
can significantly reduce outside noise.
There are a few different companies
that sell products that use this new technology, and they each come
with different features to maximize your listening pleasure.
Before you get the complete list
of the newest noise cancelation headphones, it is important to remember
that comfort, style and price are all factors to consider before
you delve into the world of hearing music and music alone. Style
is obviously important if you are going to be wearing these headphones
around town. Some headphones fit around your ears and head, others
rest on your ear and some fit into your ear(these are often reffered
to as ear buds). But, which ones provide the most comfort? People
say that ear buds can sometimes be uncomfortable after a long period
of time and that the headphones that wrap around your head provide
the most comfort for long flights or walks around town. As far as
price goes, there are a few good deals this season, so if silence
is in your budget, here are some products to try.
Bose Quiet Comfort 3 features acoustic
headphone structure, active equalization, ear cushions, an adjustable
headband, and a dual-plug and stereo-plug adapter. These headphones
run for around $350.
Sony MDR-NC50 offers to cut almost
90% of all low-frequency noise. These headphones are slightly cheaper
than Bose, at $200.
Panasonic RP-HC300 offers noise cancellation
technology for $130.
Creative HN-700 has a removable cable
that allows you to hook up to a home theatre system, and costs only
$70.
JVC HA-NC80 costs $60 and has two
different modes for filtering out ambient sound.
Now that you have a good idea of
the cost, range and function of these sound-savers, you can spread
some holiday cheer and be merry, because no matter how loud or annoying
the nagging, you won’t have to worry. You won’t hear
a damn thing.
