Hearing loss

When a part of the ear does not work well, the most likely result is a reduction in our hearing. Below we will describe some diseases in our ear that can cause hearing loss. When we have some damage to the outside or through the ear then we have the so-called conductivity hearing loss. The sound is blocked as it moves through the outside or through the ear. As the sound is not transmitted properly, the sound energy that reaches the inner ear is difficult or at least low. Conduction hearing loss can be caused by a fluid in the ear from an amount of sebum in the ear canal, damage to the bones through the ear, perforation of the eardrum.

Regardless of their appearance, all hearing aids have common features. They are made to selectively increase the volume of the sounds he wants to hear. So they can make soft sounds audible, while at the same time making loud sounds mediocre, so that they can be heard comfortably. With the advancement of technology many hearing aids can be programmed to respond differently to individual sounds and simply complement them.

No headset can solve every hearing problem or restore normal hearing, but they are designed to provide support so that your child can hear and understand better.

Neurosensory Hearing

Here the sound waves move normally through the outside and through the ear, but the inner ear does not capture the vibrations or is unable to send the vibrations to the brain. Neurosensory hearing loss can be caused by a disease, very loud noise or aging. It usually appears in both ears.

Some indications are:

  • Perception of speech and other sounds with distortion or without clarity.
  • Difficulty hearing specific tones, usually high frequencies.
  • Existence of tinnitus.

Mixed Hearing Aid

Here we have damage to both the outside and the middle ear. The sound is not transmitted to the inner ear, they are not detected and thus do not pass to the brain.

Central Hearing Aid

Here we have damage to either the auditory nerve or the auditory centers. Sound is normally transmitted through the three parts of the ear but the auditory nerve does not transmit electrical pulses to the brain or the auditory centers of the brain. An indication is that one perceives sounds but without being able to understand them.
