The SONEX Noisebuster Active Noise Canceling Earmuff is specifically designed to provide high-performance ear protection and increased safety for the industrial worker. It is also an excelent choice for do-it-yourself users of lawnmowers and power tools, as well as for motor sports fans when used in concjunction with scanners. You can even listen to your portable audio player
while wearing your SONEX NoiseBuster Earmuff. The product delivers up to 20dB of electronic noise cancellation and has a passive Noise Reduction Rating (NRR
) of 26dB
, when worn over the head.
The elctronic noise cancellation technology utilized in the SONEX NoiseBuster 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 opposite in direction to cancel 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.
The SONEX NoiseBuster Earmuff incorporates both active noise cancellation and passive protection components to offer superior performance as compared to conventional, solely passive, earmuffs.
The active noise cancellation component is the most effective defense against low-frequency noise 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.
