Hearing creates a person's basic communication system. The development of auditory structures is terminated embryonally and it has been shown that the fetus is able to respond to auditory stimuli as early as the eighth month of pregnancy.
However, not all children are born hearing. According to statistics, for every 1,000 newborns, 1-2 children with hearing loss are born, of which about half have a very severe defect.
Determining the size of the disorder is not easy, and even with the current system of examination using the child's reactions to sound stimuli, there is a significant delay in making the correct diagnosis.
