    muscles play a role in how the sound wave is moved from the air-filled ear canal to the fluid-filled cochlea. The Eustachian tube that is connected to the throat also plays an important role. 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

The sounds go via the air, down the ear canal, through the middle ear, and to the cochlea in the inner ear. The air conduction hearing thresholds are indicated on the audiogram by X for left and 0 for right.

    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

    and outer hair cells located on the medial and lateral sides of the tunnel of Corti, which is composed of pillar cells. For humans, there is one row of inner hair cells inside each cochlea numbering approximately 3,500. As for outer hair cells, there are three to five rows and are approximately 12,500 in each cochlea. The inner and outer hair cells are different in their structures, which indicates that their functions will most likely differ as well. Outer hair cells are cylinder-shaped, which

    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

    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

There are three types of deafness, first of all conductive deafness, as it means that the sound can’t pass through the outer and middle ear to send it to the cochlea and auditory nerve, second of all sensori-neural deafness as its caused by a problem in the cochlea, last but not least mixed deafness as it’s a combination of both sensori-neural deafness.

    main functional parts, cochlea and vestibular system. The cochlea is important for hearing. It is a tube filled with fluid that curls into a snail like shape. It converts patterns of sound pressure from the outer part of ear into electrochemical impulses which are then passed through the auditory nerve to the brain. On the other hand, vestibular system is important for balancing. It is the section of the inner ear where the semi-circular canals converge, near to the cochlea. The semi-circular canals
