The Influence of the Change in Frequency on Heart Rate and Work Performance
The purpose of this experiment was to test the effect of two different frequencies through heart rate and the ability to complete a task list. The relevance of this human study is associated with discovering if work performance is influenced by a particular sound frequency in a certain setting. This research especially pertains to teenagers. This general experimental design concentrates on the impact of sound frequency on heart rate and ability. Other scientists are now able to use this study in order to better understand the value of sound frequency on the human mind and body.
Moreover, to conduct the experiment, a heart rate monitor recorded the initial heart rate of the participants. They were then randomly given one of two task lists. Headphones were placed on the subject, and either the frequency of 900 Hz or 400 Hz was played; this order was also randomized. Once the list was finished, the final heart rate was written, the frequency was turned off, and the duration of the test was listed. Finally, this process was done with the other list and frequency.
After the data collection, two matched-pairs t tests were conducted. Through the statistical analyses, the change in heart rate was deemed statistically significant with a P-value of 0.0180, meaning that the regulated change in frequency had the greatest effect on the test subjects’ heart rates. In addition, it was concluded that the effect of the frequencies on the subject’s ability to quickly and accurately complete the task list was statistically insignificant, leading to a P-value of about 0.2695. When analyzing deeper into factors between test subjects, such as age or gender, gender was found to only have a minor effect on heart rate, whereas age did not have an effect at all.
