    If a tree falls does it make a sound?

    yes.... The energy transfered in the impact will generate compressional waves in the Air..... Thus sound.....

    Compression waves in the air. Yes. Is this a sound?

    If there is nobody there to detect the compression waves from the vibration of air molecules is a sound experienced?

    For something to be experienced, there must be an experiencer. Therefore no to the last version.

    Sound is the vibration of matter, as perceived by the sense of hearing.

    Strutt (Rayleigh), J W; Lindsay, R B (1877). The Theory of Sound. Dover Publications. ISBN 0-4866-0292-3.


    So no to the first version also unless there's someone around.

    Keep going down this buddist line buddy and you'll be shipped to spirituality faster than you can say "but I'm and Atheist".....😛😛😛😛😛😛😛


    From a scientific standpoint, I guess the answer is still yes, observed or unobserved the mechanics are the same. Thus the results are the same.

    But since its unobserved it COULD actually turn into a lesser spotted leopard shark and do the hokey-Cokey

    Thats a good point i guess. It depends on how you define Sound....

    Wiktionary:

    # A sensation perceived by the ear caused by the vibration of air or some other medium. (He turned when he heard the sound of footsteps behind him.) In this case it doesn't make a sound

    # A vibration capable of causing this. In this case it does......

    So my answer is whatever you like......

    It produces sound waves, caused by the vibration when the tree suddenly displaces molecules.

    sound is what is perceived by the human or dog year or whatever animal is around. if there is no receiver(nobody to hear it not even an animal) there is no sound.

    this is kind of like baseball: a ball thrown from the pitcher is still a ball no matter what the batter does. if he hits it it will be a hit ball. if he missed it will be a caught ball (caught by the guy standing in front of the umpire)

    That famous question is based on the common belief that sound means the experience of sound - which is not the case. We do not say that we 'sound'. We say that we heard as sound. Whether or not you experience a sound has no bearing on whether or not the sound exists. In reality, we will actually be affected by the sound and thus do experience it even if it takes place in a forest on the far side of the earth or on Jupiter. We just wont experience it via the sense of hearing. So no, it will not turn into a lesser spotted leopard shark and do the hokey-Cokey.

    So if I'm lost in the woods, and there are no women around, am I still wrong?

    Nobody is ever 'present' at an event. Information can only travel at or below light speed and thus we can only witness past events.
    We are still witnessing some of the big bang event via a number of means including:
    1. actual radiation that can be 'seen'.
    2. the fact that we are here.
