Which Type of Hearing Loss occurs with Damage to the Inner Ear or the Auditory Nerve?
- Last Updated: Dec 6th, 2018
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, and auditory neuropathy/dyssynchrony. A person’s hearing impairment is identified by a simple hearing test through which it is determined that how many degrees of hearing loss has been occurring compared to normal listeners.
Hearing can be done when sounds are collected and translated into nerve signal and then interpreted by our brain. Hearing can occur by the damage of any part or stoppage in that process of hearing.
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 a 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 generally, 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 the 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.
Auditory Processing Disorders
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.
If your friend or a family member has a problem in hearing then go to your nearest hearing proficient immediately. They will examine the reason and advise you treatment alternatives to suit your hearing problem. Numerous conductive and mixed hearing losses can be resolve with medicinally and all hearing impairment is treatable with hearing aids, implantable devices.
