Document Summary

Nervous system uses information concerning the time and intensity difference of sound arriving at the two ears to lo(cid:272)ate the sour(cid:272)e if sounds in spa(cid:272)e (our (cid:271)inaural (cid:862)two ear(cid:863) sound localization is extremely sensitive) Example: a sound 3 degrees to the right arrives at the right ear only 300 msec before left and we can tell direction. Conduction deafness: caused by problems involving the mechanical system that transmits sound waves to the cochlea (punctured eardrum or loss of function in bones can reduce vibration transmission) hearing aid fixes this. Nerve deafness: caused by damage receptors within the inner ear or damage to the auditory nerve itself, cannot be help from hearing aid (can happen from exposure to loud sounds) Gustation (taste) & olfaction (smell): both chemical senses because receptors are sensitive to chemical molecules. People who lose their sense of smell typically believe they have lost their sense of taste.
