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.
