Sensorineural hearing loss or deafness tends to be permanent because it involves damage to nerves or to the inner ear. The only method of treatment is a hearing aid worn in the ear, a device that amplifies the volume of sound electronically.

What are the symptoms of deafness and hearing loss?
Hearing impairment, deafness, or hearing loss refers to the total or partial inability to hear sounds. Symptoms may be mild, moderate, severe, or profound.
How does deafness and hearing loss affect the economy?
Economic impact. This includes health sector costs (excluding the cost of hearing devices), costs of educational support, loss of productivity, and societal costs. In developing countries, children with hearing loss and deafness rarely receive any schooling. Adults with hearing loss also have a much higher unemployment rate.
What is the difference between profound deafness and profound hearing loss?
Hearing loss: This is a reduced ability to hear sounds in the same way as other people. Deafness: This occurs when a person cannot understand speech through hearing, even when sound is amplified. Profound deafness: This refers to a total lack of hearing. An individual with profound deafness is unable to detect sound at all.
Is there such a thing as congenital deafness?
In the recent decade, small children, teens, and the young adults have also been found to be suffering from hearing loss. Serious cases of hearing loss which persist for an unusually long time may even lead to deafness. A number of auditory disorders are present from birth and are therefore known as congenital defects.
How are people with deafness and hearing loss born?
An individual with prelingual deafness was born with a congenital deformity or will have lost hearing during infancy. In the majority of cases, people with prelingual deafness have hearing parents and siblings. Many are also born into families who did not already know sign language. They consequently also tend to have slow language development.
Can a person with profound hearing loss hear speech?
A person with a profound hearing loss will not hear any speech and only very loud sounds. Hearing loss is in one ear (unilateral) or both ears (bilateral). Hearing loss is the same in both ears (symmetrical) or is different in each ear (asymmetrical). Hearing loss worsens over time (progressive) or happens quickly (sudden).
How can you tell if someone has profound deafness?
An individual with profound deafness is unable to detect sound at all. The severity of hearing impairment is categorized by how much louder volumes need to be set at before they can detect a sound.
What is the difference between mild deafness and severe hearing loss?
Hearing impairment, deafness, or hearing loss refers to the total or partial inability to hear sounds. Symptoms may be mild, moderate, severe, or profound. A patient with a mild hearing impairment…
