More on Hearing Protection

[JIMRPT@AOL.COM]

et al;
 As promised I am sending a reply from one of the makers of NCDs to the list
as received.  I can't make up my mind what 'was' and 'was not' said in their
reply, but they were prompt and courteous which puts them ahead of everyone
else :-)
  I have taken them up on their offer for printed materials and will share
those with the group as received.

Sirs;

 I am aware that NTC offers devices that reduce or eliminate perceived noise

and having tried a friends headset I am impressed with that particular

device.  My question is whether, in the frequency range that these devices

operate, they offer any hearing protection that would be benifical as

opposed to a hearing protection device or as being better than the naked

ear.  Thanks in advance for your response.

----THEIR RESPONSE-----------
Dear Jim:



Thank you for your interest in our technology.  I am not certain I understand
your question, however, the NoiseBuster is designed to reduce consistent, low
frequency noise.    Many people that travel, find that they are more relaxed,
and have less stress, and fatigue during travel when wearing our headsets.  So
yes these are better than the naked ear in that situation.  



In comparing Active Noise Reduction to passive, you need to understand that
high frequency waves are short and have many cycles in one second.  Passive
foam products (traditional hearing protection), will reduce high frequency
noises, but not low.  Low frequency noises can be as long as 6' and will pass
right through passive products.   There are railroad engineers that have worn
passive protection all their life, and still have hearing damage!  



Our headsets are the first headsets on the market to provide an electronic
solution to low frequency noise!  For more information on our headsets, please
send us your snail mail address.



Sincerely,



NCT
