How Does One Become Deaf: Causes and Types of Deafness
According to the World Health Organization (WHO), in 2005, nearly 278 million people suffered from mild to severe hearing impairment across the world. The Deafness Research Foundation states that nearly 17% or 36 million of American adults report some amount of hearing loss. Also, nearly 2 to 3 of every 1000 kids in the U.S are born deaf or hearing impaired. The WHO however, stresses that nearly half of all deafness-related cases can be avoided through prevention, early detection and proper management.
What are Different Types of Deafness
Deafness can be classified into three main types: Conductive, Neural and Mixed Hearing Loss. It is important to understand the type of deafness in order to plan the method of education and treatment. Conductive hearing loss refers to the disruption in the “conduction” or transmission of sound from the outer ear to the inner ear. Sensorineural or neural deafness is deafness caused by damage to the nerves in the inner ear. This type of hearing loss may be either acquired or congenital. Mixed hearing loss is essentially a mixture of conductive and neural deafness.

What Causes Deafness
Deafness, in both children and adults, can happen for many reasons. Hearing loss can be triggered by a variety of factors ranging from accidents that affect the eardrum and age-related causes to genetic factors and ear infections. In adults, the most common causes include age, noise, ear infections, wax buildup and ruptured or punctured ea drum and heredity. The Deafness Research Foundation informs us that 18 percent of Americans aged 45-64 have a hearing impairment as do 47 percent of adults 75 years or older. According to the National Institute on Deafness and Communication Disorders, nearly 26 million Americans aged 20-69 have high frequency hearing loss because of exposure to loud sounds or noise at work or during recreational activities.
In children, the top causes of hearing loss and deafness include premature birth, pregnancy-related complications and diseases such as cytomegalovirus, rubella, prenatal infections and lack of oxygen. Otitis Media, Meningitis, Down Syndrome are some of the other infections associated with hearing loss in babies and children. In fact, according to the Deafness Research Foundation, three out of four children experience otitis media by the time they turn three years.
