Hearing loss (Deafness) : Causes, Diagnosis, Symptoms, Treatment, Prognosis

Deafness means that a person has a limited ability to hear sounds. It is a communication difficulty rather than merely a loss of sound perception.



Congenital deafness affects all aspects of a child’s development: cognitive, emotional, social and educational.

Hearing Loss affects volume (loudness) and frequency (pitch).

Adults who become deaf (deafened) do not rely on hearing alone to communicate. Vision is also important.

The terms mild, moderate, severe and profound describe the extent of deafness.
