Deafness (Sensorineural and Conductive)
There are five major senses that are vital to everyday life. These senses are: sight, smell, taste, touch, and hearing. Imagine not having the ability to use one or many of your senses. Well there are many people in the world that lack one or more of their senses such as being deaf. Deafness is the inability to hear properly or to hear at all and affects every 2 to 4 of every 1,000 people according to the Gallaudet Research Center.
Deafness is usually classified as either sensorineural or conductive depending on the cause. Hearing loss can be caused by various reasons such as; heredity, aging, trauma, excessive exposure to loud noise, and diseases caused by ear infections. Sensorineural hearing loss is usually cause by too much noise exposure because it leads to the damage of the hair cells in the cochlea or hearing nerve. (Lovell and Scott) While conductive hearing loss is caused by the lack of sound able to move freely in the inner ear. Buildups such as ear wax or too much water in the ear can result to conductive hearing loss. It is possible to suffer from both types of deafness, which is commonly referred to as “mixed hearing loss”. (actiononhearingloss.com)
There are many effects of being deaf that can affect a person’s daily activities. Most effects of hearing loss are permanent, however some can be fixed surgically in some cases. Besides the inability to hear, speech production is one of the most common effects of deafness. This is considered to be true based on a study conducted by Randall Monsen and Maynard Engrebertson, which proves that deafness “prevents a speaker from learning the phonatory consequences of the muscular gestures which maintain and alter vocal‐fold tension and subglottal air pressure dynamically in the production of voice”. This effect changes how one speaks because they are not able to hear themselves talk or feel...
