What Is Noise Cancellation? | Phiaton

If you’ve ever been on a long,
cross-country flight, you are
likely familiar with the loud
hum of the jet engine
throughout the journey.

Luckily, the introduction of
noise-cancellation technology
has allowed weary travelers
to rest their ears and their
eyes on long flights.

Likewise, daily commuters are
able to use noise-cancellation
to tune out the noisy
chattering of a train-full of
people on their way to and
from work.

Yet, despite all of the benefits
noise-cancellation offers for
travel and daily commutes,
there are still many
misconceptions about noise-
cancelling technology.

Some mistakenly consider
noise-cancellation capable of
attaining complete silence,
whether aboard a noisy train
or walking through a
construction site.

The truth is that no noise-
cancelling headphone, no
matter how good the rating,
will fully eliminate high
frequency sounds, like a
jackhammer or screaming
baby.

Good noise-cancellation is
intended to minimize
ambient noise, or low
frequency noises, such as the
hum of a jet-engine, the
steady pulse of a moving train
or the sound of co-workers
bustling around you during
the work day.

When shopping for a pair of
good noise-cancelling
headphones, it’s important
that you truly understand
what noise-cancellation can
do well, and on the other
hand, what it’s not designed
to do.

So, let’s talk a little more
about how noise-cancellation
works.

Active noise cancelling
headphones contain a
miniature microphone that
observes external sounds.

By analyzing the background
noise, the noise-cancelling
circuitry takes note of the
frequency and emulates a
sound to cancel out the
noise.

This “destructive
interference” allows you to
stay focused on the audio you
want to hear.

This sound reduction
technology, however, doesn’t
work on all frequencies.

While every manufacturer is
slightly different, all noise-
cancelling headphones
operate to reduce low
frequency sounds.

The other type that you may
hear referenced, is passive
noise-cancellation.

These headphones do not use
any electronic sound
reduction technology and as
a result, do not isolate lower
frequency sound.

Just like wearing earmuffs or
putting your fingers in your
ears decreases the ability to
hear, the materials of the
headphones themselves
block out some sound waves.

Passive noise-cancellation can
minimize some high
frequency sound, however, it
will only be muffled
depending on the thickness
of the material in the ear-
cups.

Many active noise-cancelling
headphones also feature
passive noise-cancelling
qualities, including many of
Phiaton’s product offerings.

Phiaton’s active noise-
cancellation technology
allows for as much as 95%
noise reduction of low-
frequency sounds in products
such as their BT 100 NC and
BT 330 NC headphones.

The BT 330 NC also offers
some passive noise-
cancellation through the
density of its padded earcups.

To sum it all up, noise-
cancelling headphones are
most successful at reducing
low frequency background
noises, such as commuter
and travel interference.

You’ll find yourself needing
them on planes, crowded
offices or anywhere you just
want to lessen the noise
around you.

With so much ambient noise
surrounding us, it’s become
difficult to enjoy the music-
listening experience when
dealing with the
environmental fracas of our
everyday lives.

This is why the need for a pair
of noise-cancelling
headphones has become
essential for the modern
audiophile.
