This all depends on what you believe the true definition of "sound" is

Personally, i believe it would because i think sound is the vibration of waves in a medium (comma?) whereas hearing is the perception of sound

And dictionary.com contradicts itself... look at definition 1 and 2 of sound, i would post the link, but i'm still too much of a noob =p

I have a good idea that it doesn't. How can sound exist if no-one's around to hear it?

You're a dumbf**k

Because you're just ****ing retarded.

So what, if someone doesn't hear a nuclear flare going off on some star 12,000 light years away it doesn't exist?

Give me a ****ing break.

It makes a sound that nobody hears.

Quote from Exilement

Sound refers to the human perception of sound waves, which are changes in atmospheric pressure around us, which obviously occur when a tree falls.

If there's no human to perceives those waves, then no, no "sound" occurs, but the conditions that would have otherwise created it do.

Basically right. My physic's professor basically said the same thing.

If a tree falls down in a forest does it make a sound? NO

It's not considered a sound until it reaches a human ear.

If a tree falls down in a forest does it make a pulse? YES

A pulse is basically what a sound is until it reaches a human's ear.
