Types and causes of hearing loss

One of the effects of hearing loss is the ability to distinguish between speech and noise, and the ability to listen to high-frequency sounds may disappear completely. The causes of hearing loss vary, and the type of hearing loss can be classified according to where the ear is damaged. There are usually three different types of hearing loss:

Conductive Hearing Loss
Conductive hearing loss is usually temporary and can sometimes be corrected. It develops from the problem of the outer or middle ear. The cause of such problems may be:

  • infection
  • Earwax or liquid accumulation
  • Perforation of the eardrum
  • Otosclerosis (a symptom of a developmental disorder in the middle ear)
  • In many cases, such hearing loss can be cured by earwax cleaning, medication or surgery.

Sensorineural Hearing Loss
Sensorineural hearing loss is the most common type of hearing loss. In fact, 90% is the case in adults with hearing impairment. This can happen in aging and in very noisy environments. If you have sensorineural hearing loss, you are likely to notice:

  • The sound is not only reduced in volume, but also distorted.
  • High-pitched speech (such as soft consonants) is hard to hear.
  • Low-pitched voices (such as vowels) are easier to hear.

This type of hearing loss is due to problems with the cochlea and auditory nerve, which can be treated with a hearing aid or surgery. For more information on the surgical procedure, please consult your physician.

Mixed Hearing Loss
Mixed hearing loss is a phenomenon of hearing loss that occurs simultaneously with conductive hearing loss and sensorineural hearing loss.

In this case, in addition to the use of hearing aids, you must be treated with earwax cleansing, medication or surgery.

But sometimes, hearing loss is a temporary phenomenon. This situation is very common and may be caused by any of the following:

  • More earwax
  • Ear infection
  • allergy
  • Sinus problem
  • Drug influence
