Hearing loss is a common problem caused by noise, disease, aging, illness, and genetics. General signs of hearing loss occurs suddenly and develops gradually that includes asking people to repeat themselves, listening to music or television with a higher volume than required. There are two main types of hearing loss depending on where the problem lies they are conductive hearing loss, sensorineural hearing loss.
Sensorineural is caused by damage to the auditory nerve that occurs naturally with age. There are several options that help to improve a person’s ability to hear and communicate which includes digital hearing aids, cochlear implants, middle ear implants, bone anchored implants, wireless devices, etc. The 35delG mutation was detected in 11/ 712 unrelated blood donors.
The results indicate that the prevalence and severity of hearing loss amongst Jordanian infants (1.37%) is remarkably higher as compared to the Israeli infants (0.48%). The overall prevalence of bilateral SNHL was seven times more in the Jordanian infants, 18 times in non-risk, and three times in the HR infants relative to the Israeli infants. Risk factors including family history, hyperbilirubinemia, bacterial meningitis, and associated syndromes were more prevalent amongst Jordanian infants
