Document Summary

Two lines that look like they don"t line up. Long black bars don"t look like they are parallel. Diverging and converging lines make us believe that the lines are either coming together or growing apart. Purity (timbre -- the unique sound by whatever the sound is being produced by) ex: the different sounds between an oboe (breathier) vs a trumpet (cleaner, brighter) Dogs/cats can be appear freaking out that we cant hear (ex: high pitch whines from electronics charging) Rodents have narrow range, but high pitch. Humans lose high end of our hearing. Oval window (movement of bone --> movement to liquid) Must be translated to electricity so they can be moved on by neurones. Basilar membrane: full of hair, where transduction takes place. Hair cells in the cochlea vibrates and connects to neurones in your auditory nerve to send out messages to your brain. Damage to cochlea: cochlear nerve deafness --> can be improved by a fake cochlea.
