[TenTec] Argonaut V Audio

[Stuart Rohre]

Joel, actually there were extensive intelligibility tests which are quoted 
in all the acoustic text books at our lab at the "U".  I am in other 
branches of acoustics but the speech acousticians will relate that the 
restricted band 300 to 3K optimizes how well you hear something.  In fact, 
you might think of it as kids have TOO MUCH bandwidth.  If you study the 
principles of filters, narrowing the band you listen to, (or receive) 
optimizes the Signal to Noise issue.  The choice of those frequencies is 
deliberate not based on age of the person hearing the sounds, but on how the 
ear works, and its frequency response curve.
