man hears spoken language.

Degree of hearing loss

Threshold of sound perception Distance of speaking
Easy – 1 degree 26-40 decibel 4-6 meters
Medium – 2 degree 41-55 decibel 1-4 meters
Heavy – 3 degree 56-70 decibel 0.25-1 meter
Deep hearing loss – grade 4 71-90 decibel
Deafness > 91 децибелла

Why hearing is reduced

About 8% of the world’s population has hearing problems, in fact
In fact, this figure is underestimated. Since not everyone treats this
problem to specialists. Men suffer from hearing loss more often.

The organs of hearing are represented by:

  • peripheral part (outer, middle ear), conducting
  • sensory epithelium of the inner ear, perceiving the signal
  • auditory nerve transmitting impulse
  • and the central part analyzing the incoming information
    (cortical analyzer or part of the cerebral cortex in the temporal

Hearing loss may be due to damage or
diseases of any part of the auditory pathway. In addition, frequent

Conductive hearing loss

  • External auditory canal can be closed by sulfur plugs.

Sulfur is the natural secret of the outer ear, which when bad
hygienic care, frequent inflammatory diseases of the ears or
mechanical stimulations of the ear can accumulate in the form of dense

Adults are more likely to suffer from insects that get into the ear or

  • Otitis

Middle catarrhal or purulent otitis media (inflammation of the middle ear)
due to effusion can significantly reduce hearing with both one and
two sides (see otitis symptoms in children). If on the drum
membrane opens the abscess, and a hole is formed, then to
the moment of its healing or operative recovery, hearing can
completely absent on one or both ears. If healing
eardrum will occur with the formation of a large or coarse
then it will cause a persistent hearing loss on
affected ear.

  • Mechanical injury of the eardrum

This is the result of mindless tinkering in the ears. Barotrauma this

Most often, it is received by those who are struck on the ear, hunters,
who shot over the ear, as well as divers – losers.

  • The furuncles of the auditory canal with significant size and due to
    swelling can also lower hearing.

Neurosensory causes

Sensorineural or neurosensory hearing loss – consequence

stem centers of the auditory analyzer.

Congenital variants of neurosensory hearing loss – they are most often

Congenital hearing loss in a child

  • With внутриутробном заражении краснухой ребенок может родиться с
    Greg’s triad (deafness, heart disease and eye damage).
  • Fetal syphilis also leads to deafness.
  • Vertical infection with chlamydia during childbirth can be
    cause of hearing loss in the newborn.
  • Deep prematurity (up to 32 weeks) does not allow
    neurosensory apparatus to develop and leads to hearing loss.
  • In alcoholic mothers and drug addicts because of ototoxic
    actions taken substances children are often born with reduced
    by hearing.
  • Congenital Inherited Malformations – Snail Aplasia and
    Labyrinth: Mondini Shaybe, Michael, – causes of congenital deafness.
    Syndromes of Gervella (hearing loss and heart disease), Pendred
    (hyperplasia of the thyroid gland and deafness), Ushera (retinitis and
    hearing loss), Wardenburg (eyes of different colors, accrete eyebrows,
    gray strand over forehead and hearing loss), Stickler (strong myopia,
    gothic sky, early cataract, hearing impairment) – also
    hereditary congenital diseases.
  • Children with Down syndrome are often deaf already from
    of birth.

Sensorineural hearing loss

Neurosensory hearing loss can be purchased in children’s or
adulthood. In the first place of its causes – hygiene violations

  • Elderly people suffer from presbyacusis, that is, degeneration

  • The abuse of headphones affects the auditory nerves and is known
    as the “telephone operator disease”. Pathology is associated with a violation

  • Низкие частоты восприятия soundов выпадают при болезни Меньера,
    accompanied by frequent systemic vertigo and loss
    equilibrium, hearing loss and tinnitus.
  • Traumatic injuries of the temporal bone, snail. 8 pairs
    cranial nerves, cerebral cortex in the auditory centers can
    cause a secondary neurosensory hearing loss with one or
    both sides.
  • Viral infectious diseases (measles, mumps,
    herpes, rubella. flu) can damage the auditory nerves.
  • Bacterial lesions of the maze, temporal bone, Eustachian
    tubes or meninges lead to hearing loss or deafness.
  • Autoimmune diseases (eg, Wegener’s granulomatosis)
    become the primary cause of otosclerosis and hearing loss.
  • Chronic allergic rhinitis causes catarrhal
    chronic otitis, which often leads to hearing loss in children
  • Otosclerosis or growth of bone and connective tissue in

A variety of drugs have an ototoxic effect.

  • Aminoglycosides (kanamycin, gentamicin, streptomycin, amikacin)
    особенно в сочетаниях с фуросемидом дают снижения hearing
  • The diuretics themselves are, like the macrolide antibiotics

Hearing loss on the background of circulatory disorders

Often to neurologists, in addition to complaints of pain in the head or neck, noise
in the ears and ringing in the temples, sleep and memory disorders can be heard
from patients: “I hear badly with one ear”. A patient with similar

Correction of neurosensory hearing loss

Only the acute form of neurosensory can be cured completely.

understand the hearing loss that developed acutely within 72 hours and
affected one or both ears. Often patients complain: “I hear badly

Although up to two thirds of patients can continue to receive
improvement without therapy, otolaryngologists consider waiting

    also diuretic, reducing the number of endolymph in the cochlea.
  • With хронических формах тугоухости наиболее часто приходится
    resort to hearing aids. In first place today especially in
    children’s practice go cochlear implants – hearing aids,
    which can be installed inside the ear for constant wear. They have
    small size, do not cause discomfort and directly stimulate
    auditory nerve.
  • Hearing aids of various modifications from ear to ear
    require individual selection and a certain time for

    hearing aids due to poor device selection and
    inconvenience when wearing it.

Alternative ways to restore hearing
