Document Summary
Philosophical question: (cid:862)if a tree falls i(cid:374) the forest a(cid:374)d (cid:374)o o(cid:374)e is arou(cid:374)d to hear it, does it still (cid:373)ake a sou(cid:374)d? (cid:863) This questions gets us to determining what sound is. Is it strictly the product of an external stimulus (falling tree: you would say that the tree falling in the forest would make a sound, but that no one would hear it. We can all agree that a falling tree would produce sound waves. The auditory system can translate sound waves from vibrating objects into the psychological experience of audition. The falling tree would certainly produce sound waves: but the sound waves themselves do not make sound unless an auditory system is present to translate those waves into the perceptual experience of audition. Unit 2: the auditory mechanisms of different species. Humans can perceive sounds that lie anywhere between 20 and 20,000 hz.
