Creating high frequencies at high amplitudes takes more energy.

Not so much and even so, I don't care.

Not so much? All other things being equal, energy is proportional to
frequency. You say you don't care but you actuall do or at least
should.

Well I admit I am a bit rusty here, but are you saying the ultrasonic
sound
of a bat requires more energy to produce then the 7 Hz sound of an
elephant?

This response seems to be very unclear about the concept of "all other
things being equal".

A little basic physics - sound has properties of both intensity and
frequency.

Is the intensity of an elephant bellowing the same as that of a tiny bat
ranging inside a cave? The frequencies are obviously different, but what
else is different.

Of course not!

Now let's see if you can put these pieces together?
