Hearing can also occur by the damage of the auditory system. Basically, four types of deafness occur
- Conductive hearing loss.
- Sensorineural hearing loss.
- Mixed hearing loss.
- Auditory neuropathy/dys-synchrony.
Generally, the hearing is a process of gathering a sound and converting it into the nerve signal. The nerve signal receives by the brain and brain interpret the signals into responses. Hearing can occur by the damage of any part or stoppage in that process of hearing.
Inner ear damage
Individuals with inner ear loss often experience dizziness, oscillopsia, and an unstable move. If the inner ear hearing process is damage then the person can also experience tinnitus.
Internal ear disorders can be classified into two different categories:
Symptoms of inner ear damage
- Spinning sensation
- Problems with balance or walking
- Hearing loss
- Earache or ear pain
- Ringing in the ear (tinnitus)
Solutions to inner ear damage
One of the best ways to avoid inner ear damage is prevention. As inner ear damage is usually irreversible. Avoid participating in risky activities, which can lead to injury in the head: Interference with the internal acoustic artery can cause internal ear loss. Avoid ototoxic or ear poisoning, drugs that can damage the inner ear. Aminoglycosides, aspirin, quinine, and loop diuretics are drugs which may have ototoxic side effects.
Gene Therapy is a possible solution for internal ear disorders. Like the eye structure of the internal ear is similar. So, it is possible to get relatively easy access to the application of vectors, or Carriers of genetic knowledge that can be used in gene therapy.
Type of hearing loss occurs with damage to the auditory nerve?
- Sensorineural hearing loss
- Auditory Neuropathy Spectrum Disorder (ANSD)
- Auditory Processing Disorders
Sensorineural hearing loss
This type of hearing impairment occurs by the damage of auditory nerve or tiny hair-like cells of the inner ear. Due to this damage, the path of transfer of nerve signals to the brain has been blocked that’s why its also called permanent hearing loss.
Sensorineural hearing loss arises when there is harm to the nerve pathways from the inner ear (past the cochlea) to the mind or to the inner ear (cochlea). It is permanent deafness and can’t be treated medicinally.
It is not the issue of loss in hearing or the ability to hear but also affecting the speech recognition or identification and capacity to hear softly.
Sensorineural deafness can be caused by sickness, by born, drugs that are poisonous to the auditory system and hereditary diseases. Sensorineural hearing loss can also arise by noise exposure, infections, head injury, and aging.
Auditory Neuropathy Spectrum Disorder (ANSD)
Auditory neuropathy is a hearing issue in which sound enters the inner ear. But the transmission of signals from the inner ear to the brain is blocked. A Person who has auditory neuropathy can hear the sounds but can’t understand the speech correctly. It can affect people from infant to childhood. The exact percentage of people suffering from Auditory neuropathy is unknown but it relatively affects the small percentage of people.
ANSD most affected newly born infants. Kids suffering from ANSD can enhance strong language and communication skills with the help of medical equipment, therapy, etc.
- Anoxia and Hypoxia.
- Head Trauma.
- Inherited from parents (ANSD).
- Low weight at birth.
- Premature Birth.
Symptoms in a newly born child can be noticed after a time. Concerned your doctor if you notice any kind of these symptoms
- The infant does not respond to any sound.
- If your baby does not respond to your actions by babbling laughing by 8 months.
- If an infant is not making any sounds and actions by 12 months.
For any issues concerned your doctor for optimum results.
Auditory Processing Disorders
Another name is Central auditory processing disorder(CAPD). It mainly affects school-aged children.
Auditory Processing Disorders arises when the brain can’t process the information contains sound for example understanding of speech and from where the sounds coming from.
Children who are suffering from these disorders cannot process the conversations. Because the ears and brain cannot coordinate with each other.
- Difficulty in reading, writing or other languages.
- Hard to solve verbal math problems.
- Cannot understand your conversation.
- Facing difficulty in following directions which is simple or complex.
If your friend or a family member has a problem with hearing. Go to your nearest hearing proficient immediately and check if there is any kind of disorder. They will examine the reason and advise treatment.
