Over the past half-century, technology has improved virtually every aspect of human life.  
However during this period, not much has changed in the world of industrial hearing protection.  
Workers basically can choose either earplugs that are inserted into the ear or earmuffs that cover 
the ears.  These are called passive ear defenders because they employ acoustic foam to block 
noise waves from entering the ear.  This is a very effective way to protect users from high-
frequency noise, however low-frequency noise generated by engines, motors and fans is more 
challenging.  Low-frequency noise waves are longer, can carry great distances and can penetrate 
passive barriers, even cement walls.  

Now there's a new innovation in hearing protection that employs active noise 
reduction.  The NoiseBuster® Active Noise Reduction (ANR) Earmuff provides more 
complete protection from a wider range of noise frequencies, particularly low-frequency noise 
generated by engines, motors and fans that is prevalent in many industrial settings.  The passive 
component of the NoiseBuster ANR Earmuff has a very competitive Noise Reduction Rating 
(NRR) of 26dB and the ANR component provides as much as 20dB of added noise reduction within 
the low-frequency bandwidth of 20-800 Hz.  The earmuff is priced at $149.

Hearing protection is not only important for industrial workers, but for anyone who is 
exposed to noise on a regular basis.  The NoiseBuster's audio input feature makes it an excellent 
choice for do-it-yourself users of lawnmowers and power tools who want to listen to music, as 
well as for motor sports fans when used in conjunction with scanners (devices that allow fans to 
hear the radio communications of race car drivers and pit crews).  For audio to be heard in the 
presence of noise it must be overamplified above the noise, thereby creating a possible hearing 
hazard.  The NoiseBuster ANR Earmuff cancels background noise so that music can be enjoyed 
at safer volume levels.  The product delivers excellent audio quality, comparable to that of 
higher-priced, noise canceling audio headphones currently on the market.  
	
"We believe the NoiseBuster ANR Earmuff is a true breakthrough in industrial hearing 
protection," said Richard Hennessey, President, Pro Tech.  "Passive earplugs and earmuffs are 
effective against mid- and high- frequency noise, but they lose their effectiveness at 500 hertz 
and below.  Electronic low frequency noise cancellation delivers an additional level of protection 
and enables workers to hear crucial sounds such as speech and warning signals."

Mr. Hennessey continued, "Additionally, at this price point, many consumers can benefit 
from using the product while engaged in high-noise activities such as mowing the lawn.  The 
NoiseBuster is an affordable and enjoyable solution because users can listen to music without 
overamplification or distortion.  And motor sports fans won't miss one minute of the action on 
the scanner but can listen safely."

The NoiseBuster ANR Earmuff is powered with a single AA battery that provides 65 
hours of use.  The unit is resistant to water, moisture, contaminants, mechanical shock and 
vibration.  The product features soft, pliable ear cushions and an adjustable headband.  
The unit is warrantied for six months.
