Does using headphones to listen to music cause hearing loss over time?

# data[].attributes.body
600 people who were born in the 1980s and avidly used headphones

Put a poll on social media that asks for people to volunteer their time to be apart of our study and promise to pay them $550 each. We will test their hearing once every year, free of cost to our subjects

# data[].attributes.body
Our explanatory variable is how the subjects will hear their music

# data[].attributes.body
Our response variable is whether or not, in 5 years, the subject experiences a difference in their hearing abilities because of excessive headphone use to hear music

# data[].attributes.body
Listening to music through headphones VS. Listening to music out loud

# data[].attributes.body
Whether or not our subject has hearing loss due to outside factors such as concerts or loud job sites.

From our social media post we will randomly select 00 people by taking their response, assigning their post to a number, then put them in a random number generation to get our subjects

We are observing hearing loss in 600 people and so our MOE is an estimated 4.08%. This is quite a small margin of error, which is good because we aren’t testing an outstanding amount of people, and do we want to be as accurate as possible when diagnosing someone with hearing loss.

The large difference (78% to 22%) between how many people left the study with hearing loss does go to show that listening to music out loud is a much better source of hearing than is it to listen through headphones.

Team of 20 researchers, all paid $15 for each hour they spent testing the subjects over the 5 year period. The researchers spent in total 250 hours over the 5 years. We also are paying each subject $550 for their time once the study has been completed.
Salaries: 20 x 15 x 250 = $75,000
Subject payments: 550 x 600 = $330,000
Total: 405,000

Listening to music through headphones has gone to show that 78% of our subjects experienced hearing loss over the five year period of testing. Only 22% of the subjects who listened to music outloud and through headphones were lucky enough to escape with their hearing still intact

According to the data received after the study, it has been proven that headphones do indeed cause dramatic hearing loss. We are saddened to say that 295 out of the 300 subjects tested who wore headphones will or have been diagnosed with dramatic hearing loss =(

To replicate our study again we would do the same study over again but with a different selection of another 600 people born in the 80s

# data[].attributes.body
This isn’t not possible in our study because we cannot keep our subjects from knowing Howe they’re listening to music

# data[].attributes.body
People who do morning use headphones and are exposed to music through the open air
