Persuasive Essay: How The Blind See The World
How the Blind See the World
Jeremy is an eight year old blind boy who has just taken the hearing test provided by the school. The test results were astonishing; Jeremy could hear about 1.2 times better than the average sighted child. Jeremy’s teacher, Mrs. Lundsten, was amazed by her handicapped student’s hearing ability. Like Mrs. Lundsten, people throughout history have thought of blindness as a handicap and that these people can not take care of themselves. However studies have shown that this may not be completely true. This is due to the blind’s enhanced auditory skills. A prime example of the blind’s enhanced hearing is similar to echolocation. Many people who experience blindness at an early age may develop a heightened sense of hearing.
In ancient times the blind were looked down upon by others and were often considered their own class. Blindness was considered to be a punishment for social or religious transgressions or it was a result of warfare. Many ancient people …show more content…
Many animals use echolocation to communicate, avoid obstacles, locate and track flying prey, and to regulate altitude. Animals such as bats use echolocation pulses that range from twelve kilohertz to one thousand kilohertz (Wilson, 1). Echolocation is essential in the animals daily lives because without echolocation these animals would run into objects and would not be able to catch prey. Many blind individuals use sound to stimulate echolocation for the same purpose as bats or other animals that use echolocation. Blind individuals may not use this ability for finding prey, but they do use it for avoiding obstacles. There are different ways a blind individual could “echolocate”. The blind individual could use self generated clicks by rapidly moving the tongue in the palatal area, an area just behind the teeth. David Whitney and Santani Teng work at
