[Vintage-Audio] Re Frequency Behavior

[Sheldon Daitch]

Bob,

I think you essentially answered part of Duane's original
question.  Low audio frequencies will travel
further.

But then Duane makes the question more complicated,
by asking would a female radio announcer be more
audible than a male announcer, I would assume due to
"interference."  I would submit that interference to a
radio signal is going to be of a different nature than
the "interference" to conversations at a cocktail party,
plus we also have electronic filtering aids for
radio reception that we would not normally bring to
a cocktail party, unless yours are radically different
from those I usually attend!

But you have brought into the discussion much more
technical information.  Thanks,

Sheldon
