Question
If a tree falls and no one is there to hear it, does it make a sound?
Answer
Yes, it produces the necessary viberations for sound, but scientifically there is no sound if no ones ear is present to translate the viberations in to sound. Sound is not matter, it is simply human perception of viberations.
What you have just done is LITERALLY confuse the two terms of "Sound" and "Noise". Anything that produces a pressure wave through air molecules is defined as a "sound". A dog whistle makes a sound because it blows a pressure wave through air, but if a dog cannot hear it, does that mean it does not make a sound? No, It does.
ReplyDeleteHowever, a "NOISE" on the other hand is defined as a "Sound that makes an audibly detectable vibration through which one can hear." Noises must be heard to exist; they are sounds that are heard. However, a sound is just a pressure wave; it does not need to be heard. The Sun makes sound because it is literally constantly exploding, but because nobody can hear it, it doe NOT make a noise.
Why does EVERYONE get both this parable AND the answers and facts about it wrong?
