Introduction: The general relationship between aging and hearing is one in which aging over time will lead to the natural loss of hair cells in the ears. This will result in older individuals not being able to hear higher-pitched noises and sounds as well as younger individuals (Pichora-Fuller, Mick, & Reed, 2015). According to Lustig and Olson (2014), this hearing loss is often subtle and usually leads older people only to turn up the volume on the television or radio. Although the deficit is considered subtle, there is still a notable difference that can be examined by comparing a group of younger individuals with older ones. Say no to plagiarism.

Get an original essay Methods: Two groups of participants, one aged 18 to 22 and the other aged 65 or older, were presented with six tones of different frequencies. The Dogwhistler iPhone app was used to set frequencies ranging from 100 Hz to 16,000 Hz, with variable volumes ranging from 0 to 70 decibels. Each frequency was tested twice, once in an ascending trial and once in a descending trial. The ascending trials tested the frequency starting at 0 decibels and increasing up to 70 decibels. Downtrails tested frequency starting at 70 decibels, decreasing to 0 decibels. During the experiment, participants were given data sheets with an ascending and descending column for each frequency. They were asked to place a “Y” next to the decibel if they could detect the frequency at that volume. If they failed to detect the sound, they were asked to place an “N.” Ascending test values ​​(in decibels) are determined between two consecutive "Y" responses. For descending test values ​​(in decibels), they are determined between two consecutive “N” responses. From the responses of all participants it was possible to calculate the average values ​​of both the ascending and descending trials. Results: After using the collected data and finding the average for both age groups for each frequency, I was able to create a graph to show a visual difference in both age groups. What the graph shows is that at 100 Hz both age groups needed around 64 decibels to be able to hear the sound. At 500 Hz there was a little more separation. Older adults required 43.2 decibels, but younger adults required only 37.4 decibels. At 1000 Hz, the average threshold for older adults was 26.6 decibels, but for younger adults it was 24.9 decibels. At 4000 Hz, the average for older adults was 15.8 decibels and that for young adults was 13.1 decibels. At 8000 Hz older adults required 33.8 Hz but younger adults required only 25.2 Hz. Finally, at 16,000 Hz, older adults needed 66.3 Hz while younger adults only needed 50.2 Hz to hear the whistle. Overall, the two groups had a similar threshold at 100 Hz. As the frequency increases, the trend is that older adults need a higher decibel to reach their threshold. At 4000 Hz both groups require approximately the same decibels to reach their respective thresholds. From that moment the two groups then split more drastically. Older adults need a much higher decibel to hear the frequency. Please note: this is just an example. Get a custom paper from our expert writers now.

The higher the frequency, the greater the volume difference needed between older adults and adults, 2015)
