If a tree falls in the woods and no one is around to hear it. Did it make a sound?

Sound is the biological interpretation of compression waves in the air. No biology, no sound.

No!Because you can not tell . how if there would be nobody nobody could near the noise!

No, but it probably feels vibrations, which is kinda like hearing.  Snakes don't have ears, but they "hear" vibrations.

How do you define sound? The tree falling in the forest creates a pressure wave that would be heard by a listener as a sound. Does your defintion require a listener? The pressure wave exists whether or not there is one.  Merriam-Webster defines sound as:\n\n1 a : a particular auditory impression : TONE b : the sensation perceived by the sense of hearing c : mechanical radiant energy that is transmitted by longitudinal pressure waves in a material medium (as air) and is the objective cause of hearing

If they were close enough to hear it.Yes...if not...no sound is made....sound consists of a transmitter (tree) and a receiver (ears) if one is missing then its not sound.\n\nGood Luck

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

It certainly makes sound. But, there is nobody to notice his sound. Sound is also a kind of energy. Whether someone noticed or not, it can not be destroyed.

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.

It still sends sound waves through the air, yes.  It does not, however, make noise.  Because noise is defined as something we hear, and obviously no one can hear it.  I know, I have a lot of time on my hands to come up with answers.

I worked at a zoo for nine years and witnessed the birth of two calves.  In that time I never heard any make a sound.  I don't think they are mute but animals are known to be able to make sounds beyond our range of hearing.  Elephants for example can make sounds that can be heard only by elephants and communicate for many miles.

How do you know there were sound waves in the early universe?\n\nDo you know what they say about the tree falling in the middle of the forest and there is only a man to hear the noise?

use one of those canned air boat horns- they should hear it then\n\nhave you tried unplugging your phone (if its a land line)

Only if the sound can prevent Oxygen to the fire source.\n\nHowever, If the sound could cause turbulence in the air surrounding fire....Possible.\n\nMav.

if it lands on you and you scream, and nobody can hear it, are you really screaming? hell yeah you are. and that tree made a pretty loud bang too.

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.

It doesn't matter...but if you shoot a mine and no one's around, will it make a sound???

None, sound is a wave not a particle. Sound is just a wave of vibrations travelling through atoms.
