Sound can be found in every aspect of life, and the function of the ears allows one to process these noises and send them to the brain. The human ear has three main parts that work together in order to perform the necessary job: the outer ear, the middle ear, and the inner ear. The outer ear, the section that is visible to the human eye, allows sounds to enter through the ear canal. The eardrum separates the outer ear from the middle ear. When sound reached the middle ear, the ossicles, which are the tiniest and most delicate bones in one’s body, transfer the initial sounds to vibrations and send them to the inner ear. The inner ear is the home of the cochlea, which changes the sounds into neurological signals for the brain and the auditory nerves. When sound is originally made, it must go through the entire process before the brain can register that specific sound.
When one of the steps of the hearing process is not fully developed, a minor hearing loss can be triggered within that ear. Three of the main types of hearing loss include sensorineural hearing loss, conductive hearing loss, and mixed hearing loss. Sensorineural hearing loss results from faulty sensory cells within the inner ear. This type of hearing loss is often permanent, and considered as “nerve deafness”. Sensorineural hearing loss can range from mild to profound, and it is often helped with hearing aids, middle ear implants, or cochlear implants. Conductive hearing loss, on the other hand, is a problem in…
