Document Summary
Review: best meal you ever had, most pick umami or sweet, kale don"t tend to be favorite meals. Vocal cords vibrate at particular resonance to communicate. General sensory process: physical stimulus physiological response sensory experience, physical stimulus: airwaves (air vibrations, physiological response, sensory experience: Hearing loss: first high frequencies, then later the low ones, closer hair cells (high pitch) go under more stress because all sounds pass them. Otoacoustic emissions: inaudible sounds given off by the inner ear when the cochlea is stimulated by a sound, caused by the vibrations of the outer hair cells, used for infant hearing tests. Cochlear implant: put electrical array on cochlea to stimulate it externally to get to the auditory nerve. Auditory illusions: mcgurck effect, tritone paradox contain both higher and lower frequency but our brain has a preference on which to listen to, shepard tone illusion.
