if a tree falls no-one is around to hear it, it does not make a sound.

>> No.3392266

it makes pressure waves to the air

>> No.3392273

unlogic.

>> No.3392284

sound:
if physical phenomenon of air waves, yes it does
if mental phenomenon of perceiving air waves, no it doesn't

yes people have left tape recorders around and you can clearly hear a thump

OP speaks the truth.

Percieved reality is percieved... or not

If a tree falls in the forest and there's nobody around to hear it, then there is no tree.

>> No.3392458

Sound is what is perceived during a chain reaction in the nervous system triggered by a disturbance in the air cause by the falling tree. We don't really have a reliable theory of perception or conscience so it's hard to define sound, but it most certainly is a consequence of processes in the human brain, therefore OP is correct, the tree can only be the cause of the emergence of sound if there is someone there to hear it.

This problem is not about how sound works, it never was. What this problem is about is proving something without actual measurements/experience. People must think ancient civilizations were retarded as fuck if they couldnt figure out how sound works

>> No.3392485

"Sound" as conventionally understood and defined in majority of dictionaries is a physical event.
Since physical event doesnt need a perceiver in order to exist, your statement is incorrect.

>What this problem is about is proving something without actual measurements/experience.

I see your point. It's a very amusing obervation actually:

It follows logicaly from the 'mind process' definition of sound that there can be no sound if there is no mind to experience it, however there can be no proof of the existence/unexistence of sound too, since proof implies experience and experience implies the presence of mind.

Tree have potential energy. Tree falls, tree lose potential energy. However, energy not created nor lost; energy transforms. Therefore, potential energy of tree, along with kinetic energy of the fall transforms. Tranforms into what? Into sound, for a part.

I'm a quantum mechanic, and let me tell you, until an observation is made the tree is in a state halfway between making a sound and not making a sound.

If a tree falls in the woods, and nobody is around, can it be seen?
