There is is five different sense of the human body. I believe the most important sense we have is hearing. Hearing is controlled by our ears. The process for how we perceive sound through our ears is detailed, as there are multiple parts of our ears. Sound may not be as important to others as i think it is, but its the most critical sense we have. It is overlooked and it should be appreciated more as it is easy to damage your sense of hearing.

The ear contains multiple different parts. These parts consist of the auditory canal, ear drum, hammer, anvil, stirrup, round window, oval window, semicircular canals, cochlea, and tube.There are three sections to the ear, the outer, middle, and inner ear. The outer ear consist of the lobe and ear canal. These structures are basically meant to protect the more important parts of the ear, that cannot be fixed when damaged. The middle of the ear consist of the eardrum, which is a membrane that vibrates when there is entering sounds or vibrations through the canal. After the ear drum vibrates, all the motion is transferred to three small bones, the hammer, anvil, and stirrup. These motions and vibrations are then again transferred into the inner ear. The inner ear is constructed much like the middle ear but consists of several tubes going into the skull.

The mechanisms of sound interpretation are poorly understood. There is no evidence that people all hear the same, in fact the theory as that people hear differently. There has been no detailed study on how vibrations are traced to the brain . The only research method is to conduct experiments on multiple people to give them samples of sound to listen to, then let them explain what they heard. This is a hard field to study as not much progress has been made to it.

The most current theory of how we perceive hearing through different patterns of particular waveform or frequency set ups. Hearing has been compared to how we see. It is said...
