 NoiseBuster® can help reduce
dangerous exposure to noise from portable audio devices.
With the introduction of the iPod® line of MP3 players,
portable audio use has become more prevalent than ever
before. There is increasing concern that prolonged
exposure to loud music is posing a threat of noise
induced hearing loss (NIHL). This threat is especially
troubling with regard to young listeners who have a
lifetime of exposure ahead of them and who tend to
overamplify the music when using portable audio players
in noisy settings.
The
NoiseBuster® noise
canceling audio headphone can help reduce this exposure
by reducing background noise and allowing the user to
listen to music through the headphone at a more
reasonable volume level.

While using a portable audio device in a noisy setting,
a user must increase the volume of the audio by more
than 3 decibels above the ambient noise levels for the
audio to be heard. Prolonged use at these volume levels
can be detrimental to hearing.
NoiseBuster contains
patented technology that
electronically reduces low frequency background noise by
18dB. The technology works by coupling low-frequency
noise waves with their exact mirror image waves. Ideal
for use on airplanes, buses and trains, while
exercising, commuting, mowing the lawn or just walking
down the street, NoiseBuster can be used on its own for
simple peace and quiet or in conjunction with a portable
audio device for excellent music clarity without overamplification and distortion.

What is Active Noise
Reduction (ANR)?
A NoiseBuster ANR system uses a microphone inside the
ear cup (1) to listen to noise coming into the ear (2).
Using electronics (3), the system takes that information
and uses it to create a noise wave that is identical to,
but directly opposite of, the one coming into the ear.
The "anti-noise" wave is output through a speaker (4),
also located in the ear cup. When the two waves (the
noise wave and the anti-noise wave) meet, the noise is
significantly reduced (5).
In addition to a risk of hearing loss, noise poses other
potential threats to human health. Excessive noise
causes stress and anxiety and has even been linked to
physical reactions such as high blood pressure. Low
frequency noise waves are particularly problematic
because the noise waves are long and can pass through
passive barriers such as a cement wall. These waves
cannot be easily attenuated using traditional earplugs
or earmuffs.
The open-back design of the NoiseBuster headphone is
comfortable for the wearer and the product folds for
portability. The NoiseBuster achieves a good ear seal
without enclosing the ear in unwieldy, and often hot,
closed earcups. The product has been specifically
engineered for superior noise reduction and acoustic
performance by electronic noise cancellation experts.
