2 major cues that the brain uses to figure out where sound is located in the environmentintraural time difference and interaural level differenceUltimately the midbrain will be the place wherethe map of space around us is used to pinpoint the locationWhat does the pinna do?the fleshy part of the outer ear; helps us to determine if sounds are behind or in front of usSince the pinna faces forward...the perception of sounds may be changed if they are in front of us rathe than behind usIntensity differnces can be caused bythe pinna itselfAuditory distance perceptionexactly how far away it is perceivedInverse square lawas the distance from a source increases (something is farther and farther away from you) the intensity of the sound decreases; but decreases faster than the spaceIn the inverse square law what happens to the intensity?dropping off quicklyIn the inverse square law the decrease in intensitity is what?the distance squaredThe limits of visual sphere are much larger than-the auditory world that surrounds usIf you take away the fundamental frequency how can you hear pitch correctly ?the brain can figure it out because the frequency difference between the harmonics IS the fundamentalEven if you remove fundamental there is stilla powerful cue as to what the correct pitch is you hear that remains in the soundHow is it that we can pull out different sounds when they are hitting the ear together at once?auditory seeing analysis we can group them together on the basis of timbre (the dog will always have this timbre, bird etc.)Grouping by onset/offsetsounds that start at the same time probably came from the same sourceContiuity and restoration effectsit turns out the brain can still complete the sound even if it is interuptedsynthesisthe reasembaling of sensory organization
