The ear provides the “sense of hearing” so that humans can experience a wide variety of sounds, and together with the eyes, provides the majority of human sensory information. However, some people are unable to hear or always hear “inexplicable” sounds.
What is auditory deprivation?
As early as 1984, foreign audiologists discovered that if a binaural deaf patient wears only one hearing aid, the ability to understand language in the ear without the hearing aid will gradually decline. This phenomenon can be simply interpreted as “the use of incoming and outgoing”. For example, if a leg is injured and cannot move for a long time, the leg will become thin and weak.
