It doesn't require an observer to determine if it can be heard. It either can be or it can not be. Human observation is not required to make sound waves detectable. They either are or they are not detectable. Sound is not existential.

That is correct. But if the sound from the falling tree cannot be detected because nobody is around to detect it, then it cannot be heard. And if it cannot be heard, then you are saying it is not sound. So then the falling tree did not make a soundQuote:

Besides sound doesn't take a passive observance to make it sound. When sound becomes detected, it is heard. If it isn't heard it doesn't cease to he sound.Quote:

There are trillions of nuetrinos going all through our bodies (traveling in and out) that we can not see or detect in any way, but the fact that we don't observe/recognize that it is happening doesn't mean that it isn't happening.Quote:

Not if nobody wants to bother with trying to detect them. Who would care? It's obvious that if someone sets out to detect them, he or she willQuote:

Or, did the camera not actually "see" the tree falling, only the sound it made? In which case, there is no evidence at to what actually made the sound. It may well have been a bear, doing what bears are famous for doing in the woods....
I'm calling shenanagins on that documentary!
