Dee,
Excellent point. I was going for the latter - sound is best defined
as vibrations detected by the ear. Vibrations are of course created
by the trww falling, but remain only vibrations until the ear receives
them. As I understand it, anyway.
And the tree, both the one that made the sound and the metaphoric
'tree' referred to in the posting is very much still there!

Oops - missed that one! I was playing on the old "if a tree falls in
the woods, and no one hears, does it make a sound?" riddle.
You are absolutely correct - there is no sound, but the tree is still
there all right 
Good one - thanks, Dick!

You've got to define sound first. For example if you simply define it as
waveforms in the air, then yes it does make a sound. However if you define
it as the result when waveforms in the air are converted to a form that can
be interpreted by the brain, then it doesn't make a sound.
Either way though you are right that the tree is still there.
