it comes down to that old Frederick Nietsche=20
connundrum first postulated in his "Man and Superman": "If a tree =
falls in=20
the forest and there is no one there to hear it fall, did it make a =
sound?"=20

If old Nietsche had had access to Google he could have answered that. =
And the answer is: It depends on the definition of the word "sound". =
Some definitions are only about the vibrations generated, so the answer =
is "yes", the tree made a sound. Some definitions include the sensation =
in the hearing apparatus, in which case the answer is "no" because no =
one heard it, there was no sound.

In the case of the "sensation included" definitions we are back to one =
of the favourite problems in hi-fi--"If I can't hear it, or that test =
didn't hear it, then it doesn't exist." Which of course is perfectly =
correct when using that definition. And possibly incorrect when using =
other definitions.

This is one of the reasons why many discussions here go nowhere--no =
common definitions are being used.
