The Noise Buster Earphones are specifically
designed to provide high-performance ear protection and increased safety for the industrial worker. It is also an excellent
choice for do-it-yourself users of lawnmowers and power tools, as well as for motor sports fans when used in conjunction with
scanners. You can even listen to your portable audio player while wearing your Noise Buster
Earphones. The product
delivers up to 20dB of electronic noise cancellation and has a passive Noise Reduction Rating (NRR) of 26dB (over-the-head).
The electronic noise cancellation technology utilized in the Noise Buster Earphones integrates a microphone
inside the ear cup that listens to noise coming into the ear. The system analyzes that information electronically and creates
a noise wave that is direct opposite, canceling the one coming into the ear. The “anti-noise” wave is transmitted
through a speaker, also located in the ear cup. When the two waves (the noise wave and the anti-noise wave) meet, the noise
is significantly reduced.
Since the Noise Buster Earphones incorporates both electronic
noise cancellation and passive protection components, it is superior to conventional, solely passive protective earmuffs.
The electronic noise cancellation component is the most effective defense against low-frequency noises like
those generated by engines, fans and motors. The passive protection component is the most effective defense against mid- and
high-frequency noise such as speech and saws.
