Over 5% of the world’s population has disabling hearing loss (432 million adults and 34 million children). It is estimated that by 2050 over 900 million people or one in every ten people will have disabling hearing loss. Deafness refers to the inability to understand speech through hearing even when sound is amplified.
In a healthy ear, sound waves enter the ear canal and vibrate the eardrum at the end of the canal. The eardrum transmits sound waves across the three tiny bones of the middle ear into the inner ear, where the information is converted to electrical impulses (that travel along nerves to the brain), allowing us to hear.
Hearing Loss is a general term given to complete or partial loss of hearing ability from one or both ears. It is one of the most common sensory impairments seen in almost 10% of the adult population. The percentage of hearing loss markedly increases with ageing.
There are two main types of hearing loss:
More severe hearing loss can be described according to severity, as follows:
Profound hearing loss of more than 81 decibels is considered to be deafness. Deafness is defined as “a hearing impairment that is so severe that the child is impaired in processing linguistic information through hearing, with or without amplification. It is condition that prevents an individual from receiving sound in all or most of its forms.
In contrast, a child with a hearing loss can generally respond to auditory stimuli, including speech. But, 'Deaf' people mostly have profound hearing loss, which implies very little or no hearing. They often use sign language for communication.
There are various reasons why deafness occurs and may include many different causes, including injury, disease, genetic defects or ageing.
Congenital Causes: Congenital causes may lead to deafness being present at or acquired soon after birth. Deafness can be caused by hereditary and non-hereditary genetic factors or by certain complications during pregnancy and childbirth, including:
Acquired causes may lead to hearing loss at any age, such as:
Without a newborn hearing test, the average age at which congenital deafness is diagnosed is 2 years old. Children whose deafness is treated in the first months of life, gain critical time and perform far better on developmental tests than those whose diagnosis is delayed.
The National Institutes of Health and the American Academy of Pediatrics recommend that all babies have their hearing tested, preferably before they first leave the hospital.
The treatment for hearing loss is based on the cause. Temporary conductive hearing loss is often treated by properly managing the ear infections. For other types of hearing loss, treatment might involve reconstructive surgery, hearing aids, or cochlear implants (replacement inner ears). Sign language may become important to learn for the child and for his/her friends and family.
