Ok so many have tried to answer this...and there are a lot of great answers.
It's like an eternal question that really has no one answer.
It's my favorite discussion topic lol.
If a tree falls and no one is around to hear it, does it make a sound?

That has an answer and the answer is yes.
That's the same thing as say you are recording yourself speaking to your friend.
Your friend didn't hear a part of what you said.
You know you did say something and to make sure you replay the video.
The video plays back whatever you said.
Your friend didn't hear you say it, but you did make the noise.

"...sound is: "the sensation produced by stimulation of the organs of hearing by vibrations transmitted through the air or other medium."
So technically, if the energy vibrations that would cause sound never reach the 'organs of hearing', then no- it does not make a sound.
It's kind of like the 'Schroeders Cat' experiment...you never know unless you observe it, but to observe it would change the outcome..."

Sound is just the vibration of air molecules. This vibration is caused by any movement. Even the slightest movement will make a small sound, as the movement will cause the air molecules to bump into each other and make areas of high and low pressure, aka sound. A falling tree is most definitely going to make sound as it falls and when it hits the ground as the molecules will be moving and vibrating.
So, in a nutshell, yes, the tree does make a sound when it falls and lands.

It makes the necessary sound waves, but sense there is no auditory organ to pick them up and interperet them, they are not considered "sound."

Sound: The vibration of air molecules that create a high/low pressure system, or 'waves'. These waves are known as sound. Regardless of whether someone is there to hear it or not. Trust me, we went over this in physics this year in school. I could tell you all about it.

Yes, it makes a sound. Even if there is no one there to witness or hear it, it still happens.
Really, it's like saying, If you're in a dark room and there is no one to hear you're screams for help, are you still screaming?

But, I will play off of what your teacher apparently taught you. So, it requires a sensory organ to be considered "sound"? Well, animals and bugs have said sensory organs. A falling tree's sound waves are going to travel pretty far, so animals and bugs will hear it. Thus, making it sound.

Depends on your definition of a sound.
It produces sound waves as it crashes to the ground. Surrounding animals will hear it; however, if a person doesn't does that mean that it does make a sound? If we define sound as something a person hears, well then aren't we conceited?

But in the original question, wasn't there the factor of "no one" being around to hear it? .___.; [This includes, mamals, insects, blah blah, whaever living organism that has sensory organs that feel/ hear/ movements and sounds.] Though in my opinion, it still makes a sound. Hertz and vibrations in the air, along with the explanation of molecules in the air.. Sound is sound. Period, whether you hear it or not. That's the whole frustrating part about physics though.. Sometimes it seems like it's defying logic. x__x;

By saying that "no one" is around is assuming that there is nothing in the ecosystem around to support animal and bacterial life. If the ecosystem couldn't support animal or bacterial life, then it is extremely doubtful that there would be any trees around to begin with.

of COURSE it makes a sound. what kinda question is that?? stressed (one that my dad never lets me forget about) just because no one hears it doesn't mean that it didn't make a sound unless it was a very tiny tree that someohw can avoid the sound of friction as it falls. what ev, but that's my answer. talk2hand

it all depends on your definition of 'sound.'
by popular definition, yes. it does make a sound. a sound is a group of vibrations, send in wave-like patterns from the source. regardless of who's there, it makes a sound.
another definition is that sound is the percieving and deciphering of these vibrations by the central nervous system. i.e. it is the information our brain recieves when the vibrations stimulate the nerves in our ears. by this, no. it does not make a sound. it produces vibrations, but because noone is there to hear it, it will never be deciphered by a brain, and thus, will not be a sound.
