f a tree falls down in the woods and no one is around to hear it - does it make a sound? The answer of course depends on the definition of sound, as energy or as perception. Referencing a dictionary, the first two definitions describe vibrations transmitted through an elastic solid or a liquid or gas, with frequencies in the approximate range of 20 to 20,000 hertz, capable of being detected by human organs of hearing. Obviously under this meaning sound does not have to be heard to exist.
But the third definition references the sensation stimulated in the organs of hearing by such vibrations in the air or other medium. So here the vibrations must be received and be interpreted as perceptions by someone to qualify as sound. Certainty is variable.
