Document Summary
Describe a directional transfer function, and summarize wightman"s evidence that pinna shape influences sound localization. Name the 3 major planes and 3 major axes of the human body and use them to describe the 3 directions of rotation, 3 directions of translation and 2 directions of tilt. List the 5 organs of the vestibular system in each inner ear. Describe the sensory receptors in each organ, and state the effective physical stimulus for each. Describe the coding of direction and amplitude in the semicircular canals and in the otolith organs. Use vestibular system dynamics to explain: alcohol-induced head spinning, the oculogyral illusion, and the oculogravic illusion. Directional transfer function (dtf): describes effect of pinna etc. on intensity of sound across frequencies for different locations. Unique dtf obtained for each sound location (azimuth and elevation) Wightman and kistler: recorded sounds from both ear canals (dtf), and played back to subject through headphones.
