Document Summary
Module 11. 1 & 11. 2 audition (auditory mechanisms) The auditory system translates sound waves into audition: the auditory system can translate sound waves from vibrating objects into the psychological experience of audition. Just like the visual system can interpret light waves to collect information about stimuli in the environment. Therefore, trees make sound waves, but auditory systems make audition: the sound waves themselves do not make sound unless an auditory system is present to translate those waves into a perceptual experience. Species vary in the range of frequencies they can detect: ex. Dog whistles are silent to humans, but the frequency is well within the range of dogs" auditory systems. Sound frequency perception varies across vertebrates: ex. Humans can perceive sounds that lie anywhere between 20 and. Whales, dolphins, and dogs have a wider hearing range. Frogs and birds have a much narrower range of frequencies they can detect. At the low-frequency detection extreme are fish.
