Hearing loss and Deafness

Hearing loss is defined as the difficulty or inability to hear sounds, that is, the loss of hearing to hear. Therefore, when it occurs in only one ear, it is called unilateral hearing loss and bilateral hearing loss in the case of hearing loss in both ears.

Deafness is the total loss of the sense of hearing that can be caused by a variety of reasons. It can affect the outer ear, middle ear, or inner ear. People who are deaf have a hearing loss of more than 70 dB.
