if a vase falls and smashes in an empty room does it make a sound?????

no: If no one hears it, it doesn't because sound is only vibrations in the air if our ear drums don't hear it.

Nope.  No sound.  Soundwaves, yes.  Without the diaphram of the eardrum vibrating there is no such thing as sound.  Of course woodland creatures would hear it, most of them have eardrums too. (as oppose to snakes) Sound does not exist on it's own, it does indeed need a reciever to actually be considered sound.  So, taking away all creatures with an ear as a reciever... the tree will only make soundwaves.

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...

This question has been asked forever and been the subject of debate. I think the question is worded incorrectly. If a tree falls, it makes a sound. That's a law of nature. The question is did it really fall if no-one was around to see or hear it.

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

No Air --> No Pressure --> You explode from inside

Never mind. No question is a stupid question as long as u learn from it. Here's my explanation. Where does sound come from? Sound is actually produced by vibration. As long as it has vibration, it produces sound, no matter how loud or how soft. Even molecules in a solid produces sound because it vibrates, but we can't hear the sound because it is out of our hearing range. Well, as you asked, when a tree falls, it actually vibrates, hence, sound is actuallly produced although we can't hear it. For your second question, IF, lets say you are in the woods and happen to see the tree fall, and you can hear the sound of the fall of the tree. Your question was, how on earth you heard that sound, right? Here's the explanation. When the tree falls, it vibrates. When it vibrates, energy is transfered to the air. The air molecule will then vibrate and the so-called sound wave will then be transmitted into your ears.

No. And here's why: \n\nThe falling rock will create the compressions and rarefactions of air that are the external stimulus for the auditory receptors. \n\nSound, however, is more than just those compressions and rarefactions; for there to be a perception of sound there must be an organism to hear it. \n\nThis organism, in order to be able to hear a sound, must have a functioning auditory system that receives the external stimulus capable of transducing the stimulus from physical into electrical energy and have the proper neurotransmitters that will turn that electrical energy into chemical energy able to stimulate neurons. It must have uninjured neurons in the proper places that will receive that chemical energy and transform it back into electrical energy and back to chemical energy using the proper neurotransmitters to stimulate the next neurons in the chain. The organism must have all these neurons going to the proper areas of the brain that will receive the energy and impute meaning onto it from prior experience. This prior experience is why we (as verbal humans) label as sound the sensations coming from the compressions and rarefactions that hit our ears and go up the chain. Other organisms will not label the sensation as sound, but will behave in other appropriate manners indicating that they heard the sound.\n\nSo without an organism, there can therefore be no sound.

LOL!  It does indeed!  It's surrounded by air.  Sound waves travel through air.

mmmmmmmmmmmmmmmm...................it will break?

that is an ancient question like Which came first, Chicken or Egg.  Nobody knows that answer for sure.\nI believe it does not make noise, as noise is something that is created inside the head which has ears that interpret the vibrations as sound.  No ears, no sound.\nClarkie's theory on Tree Noise.

Yes they can.  If they sing a note such that the frequency of that note is the resonant frequency of the glass object, then it can shatter from being overstressed.

Sound is a sense. The tree's fall causes vibrations, but, unless something is around to interpret those vibrations as sound, it is never "heard."

yes, it makes a noise, but it doesnt make a sound.  A sound is something that someone hears

no if the item is under waranty

If you stipulate that a vibration of the air equals sound the the answer is yes.\nIf you define a vibration of the ear drum then the answer is no.\n\nTh

must be some kind of a transducer. it could also be a laser as i am not sure whether it is sound or light waves. i think it will use a laser and a sensor to detect the reflaction and hence how near it is to an object.
