If a ninja falls in the woods and no one's around to hear him. Does he make a noise?

if a ninja does anything anywhere he doesn't make a sound\nand if he makes a sound it will probably be the last sound you will ever hear.

Yes, it makes a sound....but no one is around to hear the sound being made.

Who would know?  Like, if a tree fell in a forest, and no one was there, would there be a noise?  Or, if a man said something when No woman was around, would he still be wrong?

Of course it would. There would just be no one around to HEAR it. That doesn't mean it wouldn't make NOISE! Gah, I hate when people ask this question! (No offense!)

chuck a body down there and listen for the thud. if you hear no thud then it's bottomless. if you hear one you can gauge the depth off of how long it took to hit.

NO IT DOES NOT MAKE A SOUND!\n\nto have a sound you need 3 things\n\na source to produce sound waves in a medium\n\na medium for the sound waves to pass through\n\nand a reciever to detect the sound waves\n\n\ntherefor if you have noe reciever to recieve the sound waves there is no sound.\n\nand MR Um?  i'm sorry but trees do not act as a RECIEVER for sound they in this case would act merely as an attenuation ow the sound due to reflection, scattering, and absorbtion.\n\nYOU DO NOT WANT TO ARGUE WITH AN ACOUSTIC ENGINEER WHEN IT COMES TO TALKING ABOUT SOUND!

The answer to this depends on if you are a physicist or a biologist! A physicist would say "yes" because to him/her sound is vibration of air molecules which will occur when a tree falls. \n\nA biologist, however would say "no" because sound is a perception in the brains of living things capable of perceiving it. The perception is a brain's interpretation of the nerve signals sent to it as a result of vibrations causing the eardrum to vibrate, then the ossicles in the middle ear, then the fluid in the cochlea, then the hair cells etc. There is no sound until a brain perceives it, only vibrating air.\n\nEven if the vibrations are recorded, there is still no sound until the recording is played and heard/interpreted by a capable brain.

Yes. It would be like saying things don't make sounds because deaf people can't hear it, It still makes sound, just no one is around to hear it.

No.\n\nHe would make silly quips like "Holy .........., Batman."\nIf he was just missed being burned up, for example, he might say, "Holy Bar-b-que, Batman!"

Yes it would still make a sound eventhough there is no one there to hear it because sound waves would be generated. I think the philosphical question asks whether it make a NOISE. There is a difference between a sound and a noise. A noise is a sound that is loud and unpleasant. That is a judgement call; therefore, it would necessitate someone there to hear it and make the call.

A couple of New Jersey hunters are out in the woods when one of them falls to the ground. He doesn't seem to be breathing, his eyes are rolled back in his head. The other guy whips out his cell phone and calls the emergency services. He gasps to the operator: "My friend is dead! What can I do?" The operator, in a calm soothing voice says: "Just take it easy. I can help. First, let's make sure he's dead." There is a silence, then a shot is heard. The guy's voice comes back on the line. He says: "OK, now what?"

YES!!!\n\nPhysically, yes it makes a sound, sound does not need someone to be present for it to exist.  If you're looking for some philosophical answer, this is not the place to ask it.

Well yeah it does, just cause no one's around to hear it doesnt mean the tree doesnt make a sound! I bet ya the squirrels and the deer can hear it...

Of course it does. Just because there is no one around doesn't mean that it doesn't make a sound.

This is essentially a question of definitions, i.e. how you define sound or noise. \n\nHere are the two basic answers. \n\nYes \n\nA noise is a sound and a sound is a set of vibrating molecules referred to as sound waves. If a tree falls in the forest and makes a sound, it makes molecular vibrations, or sound waves, whether any human ear drum is around to sense them or not. So yes, it makes a noise. A person hearing it is irrelevant to the being of the sound. A person hearing it is only relevant to human consciousness of the sound. \n\nAnother argument for this viewpoint is based on theology. God observes the entire universe. \n\nNo \n\nIf a tree falls, and no one is around to hear it, it does not make a noise by definition. What is noise? What is sound? One must make sure to look at this question not from such a skewed view point to realize that he or she is being misled. From an early stage in our lives, through modern science, it is FACT that sound waves are processed in our brains, thus if we are not near the sound it is just an assumption that it does make a noise. \n\nSound travels through our ears, into the canal, and into the brain to allow for it to be processed by the brain, allowing for us to differentiate due to experiences that yes, it is that particular noise. However, one would not know the sound to be that way if they cannot imagine the situation. Thus, a human being or another entity must be present to absorb the vibrations, waves, etc in order to process the information. \n\nSome take this further and claim that the whole universe does not really exist until it is observed.

Maybe, maybe not.  He might be in stealth mode.  When I log on, my messanger logs me in as invisible.  Why don't you just ask him.

Actually, no it doesn't. The sound you hear is actually vibrations in your ear that your brain converts to noise. So if there are no living creatures with ears and brains around to 'hear' it, it does not make a noise...just some air vibrations going all over the place.
