Document Summary
Variation in auditory single in frequency and amplitude over time. Physical properties of the anatomy exploited to introduce additional dimensions long which to code the input, which initially is along a single dimension of time. Unique hearing for every individual (like everyone"s cones and rods are di erent ) What we extract from the environment in terms of sound is unique to each person"s ears. Small di erence in arriving of the same signal in di erent parts of the ear (like motion visual system) Bigger ears = more frequent use of ears than humans etc) Not a one stage process like eye but a multistage process in ear. Change di erence of air pressure from pressure to movement of physical body through the ear. Three bones help us translate the air pressure into neurons that the brain can use to detect sound.
