The eardrum plays a huge role in what it does with the sound wave. The eardrum is like a small version of a trampoline on the inside of your ear. On the other side of the eardrum is the fluid-filled cochlea. The eustashian tube helps with equalizing pressure on both sides of the eardrum, which allows the eardrum

    into electrical signals that we can understand in our brain. The normal-hearing person already has a way to code acoustic sounds when the inner ear (cochlear) is functioning. The cochlea is the sensory organ that transforms acoustic signals into electrical signals. However, a deaf person does not have a functioning cochlea. The cochlear implant takes over its function. Technically, it is relatively easy to send electrical current through implanted electrodes. The more difficult part is to make the

    hearing loss is defined as a loss of “30 dB or more in three sequential frequencies in the standard pure tone audiogram within three of fewer days”(Scheiber). The loss occurs when there is damage to either the eighth nerve or the hair cells of the cochlea. Loss is typically unilateral, although in about 5% of cases, bilateral hearing loss has been observed. The average age for the hearing loss is between 50 and 60. There are no sex preferences. The hearing loss can affect all frequencies. Tinnitus

    The World Health Organization had estimated approximately 278 million people internationally are impacted by moderate to profound hearing loss in both ears. Diagnostic medical records from the World Health Organization proposed that the incidence of hearing loss frequently increases due to the population ages and life expectancy rate improving. Additionally, according to healthyhearing 2012, the majority of type of hearing loss people experience are sensorineural hearing loss; hair cells in the inner

    hair cells damaged were recorded. They reported that after 10 days the number of hair cells had decreased mainly in the basal and middle part of the cochlea. In birds that lived up to 30 days after the acoustic trauma the hair cell loss was not as severe. Similarly to the 10 day birds the mainly region of damage was located in the middle of the cochlea. Furthermore the percentage of dead/loss hair cells was 70% and 31% in the 10 day and 30 day birds respectively. In birds that were allowed to live
