Document Summary
Sound = the product of an external stimulus making a sound, but no one would hear it. On the other hand, sound may be the result of our own sensory processing, thus if no one there to hear the tree fall, the tree did not make the sound. The auditory system can translate sound waves from vibrating objects into the psychological experience of audition. The sound waves themselves dont make sound unless an auditory system is present to translate those sound waves into to perceptual experience of audition. Auditory mechanisms vary across different species according to specific needs. Sound frequency - dog whistle produces a sound at a high frequency that is beyond the range of human ears but well within the range of the dog"s auditory system. Humans can perceive sounds that lie anywhere between 20-20,00 hz. Audible frequency range is determined in part by the evolution of the structures of the auditory system.
