Document Summary

Function of ear: ear is design to measure the sound pressure of differences, intensity and frequency. Cochea: movoement of the oval window down the fluid brain. movement of fluid moving down depend on pressure. Where it got bend depend of the sounds frequency. Higher frequency bend the basal membrane closer to the oval window. Fucntion: the cochlea is a fluid-filled structure in the inner ear responsible for converting the vibrations of sound waves into electrochemical impulses known as action potentials. When there is movement in the basal membrane, the cilia bends and the sound move through to the auditory nerve. Low frequency, more vibration on the basilarl membrane. : is the process in which changes in the sensitivity of sensory receptors occur in relation to the stimulus. occurs when sensory receptors change their sensitivity to the stimulus. ans: when you have astatic stimulation that remains. Give 2 similar sounds, can identify the differences.
