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.
"Reverse education therapy" refers to the effective education of these people, to directly benefit the hearing-impaired. In children, hearing restoration together with early detection and effective rehabilitation enable up to 80% to 90% of those born with significant hearing loss to cope well in mainstream education. The infrastructure to support them and facilitate their integration into mainstream society is necessary, and some of these are in place in Singapore. Leisure time noise-induced hearing loss in children is becoming increasingly important.
