Hearing and Hearing Aid

Hearing is defined as the process of perceiving sounds. This process begins from the aurical tha collects the sound. Sound is transmitted to the eardrum through the ear canal. The sound vibrates the eardrum (like a drum). This vibration, which occurs in the eardrum, moves the bones (respectively the incus, the malleus, the stapes) located in the middle ear. Vibrations transmitted to the oval window from the stapes reach the cochlea. As the fluid in the cochlea vibrates, the hair cells are activated and the sound reaches to the brain as an electrical signal through the auditory nerve. The act of listening is realized through the perception of sound in the corresponding parts of the brain. Devices that are used, when there is no possibility to correct the hearing through treatment, and that enable hearing with a prosthesis are called “Hearing Aids”. Also; Hearing aids are recommended according to the level of hearing loss for patients who cannot be treated with medication and who require a cure for their hearing loss.
