Week Two Presbycusis Paper
Presbycusis is a condition affecting the hearing of many adults. There are a variety of causes, including damage to structures of the middle and inner ear. The result is loss of hearing—not complete deafness, but difficulty in detecting certain sounds within the normal range of hearing. Use each numbered item as a required subheading in your paper. Students should preview the grading rubric before beginning the assignment.
- explain how normal hearing occurs. Include in your discussion the following points:
- How is sound transmitted from the environment outside the body to the inner ear? What structures are involved, and how do they transmit sound?
- What happens in the inner ear (cochlea) when sound waves are converted to neural signals? How is sound frequency (pitch) processed?
- Next, summarize the causes of presbycusis and explain how they will interfere with the normal processing of sound as outlined above.
- Discuss one source of presbycusis involving a problem with the outer/middle ear.
- Discuss one source of presbycusis involving a problem with the inner ear.
- Finally, describe what it might be like to have presbycusis. Include the following points:
- If you have normal hearing now, how would your ability to converse with others be affected?
- What activities that you now enjoy would be limited by this condition?
- How would such a condition affect your work life?
The paper should include:
- Be a minimum of 3.5 and a maximum of 4.5 full pages, size 12 font Times New Roman, double spaced with 1 inch margins, NOT including the Title and References pages.
- A title page
- Include the sub headings of: “Introduction”, “How Normal Hearing Occurs”, “Causes of Presbycusis”, “Having Presbycusis”, and “Conclusions”.
- Introductory paragraph ending in a clear thesis statement
- Several well-developed (5-7 sentences) body paragraphs that explore the assignment questions in detail
- A summary and conclusions paragraph
- Three references, two of which cannot be from the class readings.

Introduction
The human ear is the organ that is involved in the perception of sound in people. The
organ enables people to communicate by detecting the various characteristics of sound and
enabling the nervous system to transmit the information to the brain for processing. Therefore,
any diseases that affect the sensitive parts of the ears may jeopardize the survival of humans
because it will make them unable to communicate (Stamper & Johnson, 2015). Communication
is essential in humans because they are social creatures who need to exchange messages and
make sense of them to mate, avoid danger and conduct other daily activities. Presbycusis is a
disorder that affects the hearing function among adults. Even though it does not lead to the total
loss of hearing, it reduces the ability of the ears to detect sound.
How Normal Hearing Occurs
Air Conduction of sound and Outer ear
Hearing is an extensive process that starts from the out ear to the inner ear and is also
concerned with the conduction of sound waves. During the process of hearing, the outer ear
channel the waves of sound from the environment to the tympanic membrane. The auricle
collects the waves while the cochlea funnels the sound into the canal. The auricle is the outer
visible pa...
