Helen Keller, deaf, dumb, and blind, is credited with saying that she would value above all other senses the sense of hearing that instrument of intercourse with others without Which the sound of the human voice is lost and one becomes engulfed in an indescribable loneliness. Living in lonely silence day after day, year after year, it is small wonder that the deaf become depressed, irritable and dependent.
