Sensory impairment occurs when one of the senses like sight, hearing, smell, touch or taste is not functioning normally. Visual impairment limits eye or vision function. Hearing impairment prevents receiving sounds through the ear and can range from difficulty hearing faint sounds to not distinguishing any sounds. Multisensory impairment involves a combination of visual and hearing loss, intensifying the impact. Common smell and taste disorders include anosmia, ageusia, hyposmia and hypogeusia which reduce or distort odors and tastes and can affect quality of life.
