FUNDAMENTAL DIFFERENCES AND BENEFITS OF HEARING BEHIND THE EARS AMPLIFICATIONS AND COCHLEAR IMPLANT WITH HEARING SENSOR NEURAL IMPAIRMENTS

Abstract

The aimof the hearingamplkification in aperson with impaired hearingis to use the remaining auditory potentials. One of the most important factors affecting the success of the auditoryand speech prcertion in a person with impaired hearing is the time and the quality of the amplification.The main purpose of the hearing aids is to make the sound signal available for the damage ear, to transfer the sound information as accurately as it can , and to adjust the transmission and the quality of the of the sound information to the receptive capacity of the ear to the highest degree. The purpose of this paper is to show the difeerence in the transmission of of the sound signal with the hearing amplifications and the cochlear implants, as wellas their benefits. 31 patients were tested for the purpose of this paper, and their aural condition was measured three times:without a hearing amlification, with a hearing amplification and finally with cochlear implant. The obtained results show that the benefit of the cochlear implants is much larger than the one of the hearing amplifications.
