Living without one of your senses is more difficult than some of us imagine. However, many people suffer from such disabilities, with hearing loss being a common occurrence.
According to the most recent research, approximately 5% of the world’s population, or 34 million adults and 32 million children, suffer from hearing loss. Despite the large number, there is no need to panic because scientific advancements have provided us with better tools to deal with the situation.
What Exactly Is Hearing Loss?
Hearing loss is defined as the inability to detect another person’s voice. It comes in three varieties. But, before we get into the different types of hearing loss, let’s look at the parts of the ear and how they work.
Outer Ear
The ear is divided into three sections: the outer ear, the middle ear, and the inner ear.
It refers to the visible area, which includes the ear canal and pinna. Its job is to collect ambient soundwaves and direct them into the ear canal.
Middle Ear
The middle ear contains three ear bones in an air-filled cavity that aids sound transmission from the eardrum to the bones that carry it further into the inner ear.
Inner ear
Here, we can see fluid-filled membranes and the cochlea, a snail-shaped chamber that transports sound waves to the brain. The cochlea contains tiny sensors that convert sound vibrations into electrical impulses before sending them to the brain.
Hearing Loss Types:
Conductive
The condition in which hearing loss occurs as a result of a malfunction in the outer and middle ear.
Sensorineural
Sensorineural hearing loss occurs when the inner ear malfunctions.
Mixed
Mixed hearing loss occurs when a person has both conductive and sensorineural conditions.
What Are the Common Causes of Hearing Loss?
Hearing loss in children and adults is caused by a variety of factors, the most common of which is ageing. Among these causes are-
Eardrum Impairment (Tympanic Membrane Perforation)
An eardrum rupture can be caused by a loud blast, poking with sharp objects, or recurring infection. All three can cause an eardrum rupture. The conditions have a high likelihood of causing partial or total hearing loss.
Earwax Accumulation
Earwax buildup can cause a blockage and impede soundwave flow. The condition can cause temporary hearing loss, but in most cases, removing ear wax resolves the issue. However, it is recommended that you see a doctor for earwax removal, or you may end up with a ruptured eardrum.
Ear Infections Are Common
If you get ear infections every three months, you should see a doctor and take medication because these can damage your eardrum and cause hearing loss.
Tumours or Bone Development
Three bones make up our middle ear. If any of these develops abnormally, it can cause ear damage and hearing loss.
Injuries to the Inner Ear
The inner ear works by converting sound vibrations into electrical waves and sending them to the brain. However, as people age or are exposed to loud noises, the transmissions become less effective, resulting in partial or complete hearing loss.
Is it Possible to Reverse Hearing Loss?
Unfortunately, treatment cannot reverse all hearing losses, except those caused by ear wax blockage. However, seeking medical attention at the appropriate time can help you control the situation and avoid total hearing loss. Here are some suggestions for preventing ear degeneration:
- Seek medical attention if you are experiencing hearing loss.
- Make use of hearing aids.
- Plastic earplugs are useful in loud environments.
- Conduct regular hearing tests.
Our hearing health is determined by how we care for it. Poking the ear is forbidden since childhood and must be followed. Avoiding loud noises will also keep your ears healthy for a long time. However, if you experience hearing loss, see a doctor immediately and take appropriate medication.
The central auditory pathways are the neural structures and pathways that transport sound from the ears to the brain. The sound is then translated into words or sounds that we recognize by the brain.
