  • Ear canal
  • Eardrum

  • Semicircular canals
  • Eustachian tube
  • Cochlea
  • The sound is first born through the hitting of the drum. It is created via the air molecules vibrating against each other, making a sound percieved by humans as thick and heavy.
  • Auditory Cortex
  • The sound wave goes in all directions across the room. The wavelength of the sound is strengthened and weakened as the sound wave is absorbed by the walls but some of it bounces off the walls, coming back and amplifying the echo of the sound.
  • At an incredibly fast speed, (343 meters per second) the sound wave reaches the ear. It moves through the fluid in the cochlea in the inner ear, eventually resulting in the transformation of the sound wave into an electrical signal headed for the brain.
  • This new signal makes its way to the brain, where the signal is read and determined by the brain, forming the sound that is perceived by the human from the drum. All of this happens in merely a fraction of a second.
  • One innovation that can help improve this process for people with poor hearing is a cochlear implant. Invented by André Djourno and Charles Eyriès in 1957, the cochlear implant is a device surgically implanted into the human ear to aid people with minor to major hearing loss. The implant takes over the normal process of how sound is perceived and instead converts sound waves into electrical signals itself that are then read by the auditory nerves.
  • Innovations such as this can help people with poor hearing especially people with previous hearing aids.
