PSYCH 1XX3 Lecture Notes - Lecture 11: Basilar Membrane, Oval Window, Sine Wave
Document Summary
Is sound the product of an external stimulus (tree makes sound) Or is it the result of our own sensory processing (tree makes no sound) Auditory system can translate sound waves from vibrating objects into the psychological experience of audition. Sound waves themselves do not make sound unless an auditory system is present to translate those sound waves into the perceptual experience of audition. Sound is the result of our interpretation of waves. Unit 2 : the auditory mechanisms of different species. Auditory mechanisms vary across different species according to specific needs. Range of frequencies that can be detected differs between species. Example: dog whistle doesn"t produce audible sound to human ears. Dog whistle produces sound at a high frequency that is beyond the range of human ears. Humans can perceive sounds that lie anywhere between 20-20,000 hz. Whales, dolphins, dogs have wider hearing range. Frogs and birds have narrower range of frequencies they can detect.
