Sound - Term Paper ExampleIn this essay we are going to access the health effects of sound contaminant to the human capitulum (Roberts, 6).Noise contaminant is caused by industrial machines, building machines, motor vehicles, trains, and aircraft. This noise is produced in excess that is harmful to the human ear. Noise pollution has negatively affected the lives of people. There has been a direct link of noise pollution with health. Problems connected with noise pollution includes diseases related with stress like luxuriously blood pressure, loss of hearing, interference with speech, disruption when sleeping and lose productivity. The most commonly discussed disease is the Noise Induced Hearing Loss (NIHL). Research has shown that aeonian exposure to high levels of noise can cause numerous unfavorable health effects. (United States Comparative Ranking, 1975. 8) Noise pollution can cause hearing loss, unwashed auditory function of ones ears are affected by too much noise. One is considered to have the ability to hear if he is overt of detecting sound within the frequency of 16-20,000 Hz. The diagram below shows how the human ear functions. The threshold of audibility or the point at which sounds are provided detectable is shown below. In clinical hearing evaluation, normal hearing falls within a range of 0 to 25 dB of the threshold of audibility. .The efficiency to hear means being able of detecting sounds within the frequency range of 16-20,000 Hz. The threshold of audibility or the point at which sounds are merely detectable is shown in Figure 2-2. In clinical hearing assessment, normal hearing falls within a range of 0 to 25 dB of the threshold of audibility. To understand more about the effects of sound to our ears, we are going to see the parts of the ear in the diagram below.The outer ear has the auricle or pinna 1 the auditory canal 2. The pinna of human ear is a residual composition though it may aid in the localization of sound
