[Vintage-Audio] Re Frequency Behavior

[Sheldon Daitch]

Duane,

Maybe we are trying to compare apples and oranges here.

In general, lower audio frequencies are attenuated less than
higher frequencies, thus, you can hear the rumble of the loud
bass much further away than the higher frequencies from the
same boom box.

When you get into the second part of your question, which
announcer would be "heard" at a greater distance, assuming
no interference, one would think there should be no
difference in radio range, if that is the intent of your question.

Now let's subject the signals to some interference, and
then it becomes a little more difficult to answer, as the filtering
necessary to reduce or eliminate the interference  might also
be the same frequency range as the announcers voice.

So now, at the RF side of the equation, I am at a loss for
a definitive answer, as I think it might be a lot more
subjective and related to the skills of the listener.

More thoughts?

Sheldon
