Watch this video about: Hearing and the cochleaīalance (equilibrium) is controlled in the inner ear. The vibrations are changed into nerve signals in the inner ear and are carried to the brain by the auditory nerve. Hearing occurs after sound vibrations cross the eardrum to the inner ear. One is hearing and the other is maintaining balance. Devices such as glasses and hearing aids, or lifestyle changes can improve your ability to hear and see. You need more stimulation to be aware of the sensation.Īging can affect all of the senses, but usually hearing and vision are most affected. This minimum level of sensation is called the threshold. There, the signals are turned into meaningful sensations.Ī certain amount of stimulation is required before you become aware of a sensation. Sensory information is converted into nerve signals that are carried to the brain. This information can be in the form of sound, light, smells, tastes, and touch. Your senses receive information from your environment.
You may have problems communicating, enjoying activities, and staying involved with people. Sensory changes can affect your lifestyle. Your senses become less sharp, and this can make it harder for you to notice details.
