ENTHearing Loss

Does it feels hard sometimes to hear what someone is saying?Its a sign of Hearing Loss by Dr Aditya Nandan

In general, there are 2 types of possibility from which a person can suffer, it can be “Hard To Hear” or it can be “Deafness”.

Hard Of Hearing:- Those in whom the sense of hearing is present But defective in functional with or without hearing aid.

Deafness:- Those in whom the sense of hearing is non-functional for the ordinary purpose of life.

Blindness separates us from things but deafness separates us from people.

How Many Types of Hearing Loss Are There??

The main types of hearing loss are sorted into 4 categories: Sensorineural, conductive, Auditory Neuropathy Spectrum Disorder and mixed.
Sensorineural which means there is a problem occurring in either the inner ear or the auditory nerve, which delivers sound to the brain.

Conductive which means the sound does not reach the inner ear, usually due to an obstruction or trauma.

Mixed means the hearing loss is being caused by a combination of the two of the above.

Auditory Neuropathy Spectrum Disorder means hearing loss that occurs when sound enters the ear normally, but due to damage to the inner ear or the hearing nerve, the sound isn’t organized in a way that the brain can understand

Sensorineural Hearing Loss:-

It is the most common type of hearing loss i.e. sensorineural. It is a permanent hearing loss that occurs when the damage occurs in either the tiny hair-like cells of the inner ear or the auditory nerve itself, which prevents or weakens the transfer of nerve signals to the brain. These blocked nerve signals carry information about the loudness and clarity of sounds and transfer it to the brain. 


  • Normal aging
  • Extremely loud noises or noise exposure for an extended period of time
  • Traumatic injuries that damage the inner ear or auditory nerve
  • Infections such as meningitis, mumps, scarlet fever and measles ‘
  • If a child is born with sensorineural hearing loss, it is most likely due to a genetic syndrome or an infection passed from mother to fetus inside the womb, such as toxoplasmosis, rubella or herpes.
  • Cardiovascular diseases


  • Noises may seem too loud or too quiet (yes, too loud!)
  • Speech of others may seem slurred or mumbled, or, a feeling of you can hear but not understand
  • Difficulty following a conversation when two or more people are speaking at the same time
  • A consistent ringing or buzzing in the ears (tinnitus)
  • Problems listening in noisy environments (e.g. train stations, construction sites, convention centers, sports arenas, etc.)
  • Difficulty hearing women’s or children’s voices
  • Certain speech sounds are difficult to hear during conversations
  • A feeling of being off-balance or dizzy

Cure and Treatment:-

There is no medical or surgical method of repairing the tiny hair-like cells of the inner ear or the auditory nerve if they are damaged. However, sensorineural hearing loss can be treated with hearing aids or cochlear implants, depending on the severity of the loss. 

Assistive listening devices, like alerting devices, vibrating alarm clocks and captioned phones help provide a complete hearing solution. For people with severe-to-profound hearing loss, power hearing aids can help. 

Conductive Hearing Loss:-

A less common type of hearing loss is conductive hearing loss, which occurs when there is an obstruction or damage to the outer or middle ear that prevents sound from being conducted to the inner ear. Conductive hearing loss may be temporary or permanent, depending on the cause. 


The causes of conductive hearing loss can be differentiated by which part of the ear they affect—either the outer or middle ear:

Outer ear:-
  • Stenosis or a narrowing of the ear canal
  • Wax impaction
  • Exostoses (bone-like protrusions that can develop inside the ear canal and cause potential cause blockages)
  • Otitis externa also is known as swimmer’s ear
  • Obstructions caused by foreign bodies inserted into the ear
  • Microtia
Middle ear:-
  • A breach in the tympanic membrane or eardrum caused by injury, ear infections or extreme and rapid air pressure changes
  • Tympanosclerosis, a thickening of the tympanic membrane
  • Otitis media (ear infection) and/or a buildup of fluid in the middle ear
  • Blockages in the Eustachian tube, which connects the middle ear to the back of the nose and throat
  • Otosclerosis, a rare medical condition that causes the middle ear bones to freeze-up
  • Abnormal growths or tumors that form within the middle ear, such as cholesteatoma or glomus tumors
  • Ossicular chain discontinuity, or a break in the connection between the bones of the middle ear, caused by injury or heavy trauma


Because the sensitive inner ear and auditory nerve are intact, individual suffering from conductive hearing loss primarily has difficulty with the overall loudness of sounds, but not the clarity. Individuals with this kind of loss often find that turning up the volume of the radio or television is all it takes to improve their ability to hear. The following symptoms are also consistent with this type of loss:

  • Easier time hearing out of one ear than the other
  • Pain in one or both ears
  • The sensation of pressure in one or both ears
  • Difficulty or frustration with telephone conversations
  • A foul odor coming from the ear canal
  • A feeling that one’s own voice sounds louder or different


There are sometimes medical or surgical treatments that can improve the hearing ability for those with conductive hearing loss. For example, conductive losses caused by wax impaction, foreign objects, abnormal growths or ear infections can often be corrected with medical treatments, like extraction of earwax, antibiotics or surgical procedures. These causes usually result in temporary hearing losses. The treating physician and hearing healthcare professional will monitor hearing ability and work with the patient to determine when and if a hearing solution is needed.

Conductive hearing losses caused by other abnormalities, like stenosis of the ear canal, exostoses, otosclerosis, and ossicular chain discontinuity are more difficult to treat medically and may be considered a permanent hearing loss. These conductive losses may be treated with either standard hearing aids or bone-anchored implantable devices. 

Mixed hearing loss

Mixed hearing loss is any combination of sensorineural and conductive hearing loss. 


Mixed hearing loss commonly occurs when the ear sustains some sort of trauma. It also can happen gradually over time when one hearing loss is compounded by another. For example, a person with a long-standing conductive hearing loss might experience age-related hearing loss as they age. Alternatively, a person with age-related hearing loss may have a temporary mixed hearing loss due to wax impaction.


The symptoms of mixed hearing loss will be some combination of those listed above for the other two types of hearing loss.


Treatment options for mixed hearing loss will depend on whether the loss is more sensorineural or conductive in nature. If a greater portion of the loss is caused by a conductive component, surgical procedures and other medical treatments might be more effective in correcting the hearing concerns. If a greater portion of the loss is sensorineural, hearing aids or implantable devices may be the best option.

Hearing Loss Can Also Be Described As:

  • Unilateral or Bilateral:-
    Hearing loss is in one ear (unilateral) or both ears (bilateral).
  • Pre-lingual or Post-lingual:-
    The hearing loss happened before a person learned to talk (pre-lingual) or after a person learned to talk (post-lingual)
  • Symmetrical or Asymmetrical:-
    Hearing loss is the same in both ears (symmetrical) or is different in each ear (asymmetrical).
  • Progressive or Sudden:-
    Hearing loss worsens over time (progressive) or happens quickly (sudden).
  • Fluctuating or Stable:-
    Hearing loss gets either better or worse over time (fluctuating) or stays the same over time (stable).
  • Congenital or Acquired/Delayed Onset:-
    Hearing loss is present at birth (congenital) or appears sometime later in life (acquired or delayed onset).

The Degree Of Hearing Loss:-

  • Mild Hearing Loss
    A person with a mild hearing loss may hear some speech sounds but soft sounds are hard to hear.
  • Moderate Hearing Loss
    A person with a moderate hearing loss may hear almost no speech when another person is talking at a normal level.
  • Severe Hearing Loss
    A person with severe hearing loss will hear no speech when a person is talking at a normal level and only some loud sounds.
  • Profound Hearing Loss
    A person with a profound hearing loss will not hear any speech and only very loud sounds.

In India more than a million people every year use to lose their hearing ability completely and the becomes disabled and the reason can be many From not taking proper and right time care of ear to unhealthy diet or listening high volume music on headphones.
