The Anatomy of Ears and Types of Hearing Loss

The ear is our body organ of hearing. Hearing loss can vary from light to profound as well as has various reasons, consisting of injury, genetic defects, condition, and the aging process.

Two kinds of hearing loss are conductive hearing loss and sensorineural hearing loss. If anyone has a combination of both conductive as well as sensorineural hearing losses, it is called a “blended” hearing loss.

Hearing loss during birth is called a genetic hearing loss while hearing loss that takes place after birth is called acquired hearing loss. The most common root cause of gotten hearing loss is sound, which represents over one-quarter of people impacted by hearing loss.

Ear anatomy

The ear consists of three different parts:

  • External ear: This is the part you can see. Its form assists in gathering acoustic waves. The tubular form of the ear canal leads internal to the tympanum
  • Middle ear: This is divided from the external ear by the tympanum. The center ear consists of three small bones called the hammer bone or malleus, the incus or anvil bone, and the stapes or stirrup bone. These bones enhance the activity of the tympanum created by sound waves. The Eustachian tube links the middle ear with the rear of the throat as well as aids for equalizing air pressure
  • Inner ear: Ear receives sound waves through a spiral-shaped organ known as the cochlea. Hairs over the cochlea are responsible for sensing the resonance and transferring the message, translated right into electric impulses, on to the brain using the cochlear nerve.

Conductive hearing loss

Conductive hearing loss influences the transmission of noise between the external as well as the internal ear. As an example, this may be brought on by:

impacted wax in the ear canal

  • failing of the three tiny bones inside the middle ear to pass along sound waves to the internal ear
  • failure of the tympanum to vibrate in response to sound waves. A fluid build-up in the middle ear, as an example, could dampen the activity of the tympanum.

Oftentimes, treatment is available for conductive hearing loss as well as the normal hearing will return. You can visit the link

Sensorineural hearing loss

This loss occurs as a result of any damage to the inner ear or the cochlea. For instance, sensorineural hearing loss can be brought on by condition, injury, or some other disruptive occasion targeting the cochlea and/or the cochlear nerve. The remaining ear, consisting of the small bones as well as eardrum, might be working; however, the electrical impulses cannot reach the brain

The majority of instances of sensorineural hearing loss do not reply to therapy
