The Apple Hearing Study is sharing new data from thousands of participants across the US in an effort to help people better understand their hearing health.
The Apple Hearing Study is one of the studies launched within the Research app that are helping democratize how medical research is conducted by giving Apple customers the ability to participate in groundbreaking research using technology they’ve already made a part of their everyday lives. The study is being conducted in collaboration with the University of Michigan School of Public Health, and data is being shared with the World Health Organization’s Make Listening Safe initiative.
By the numbers
The insights generated in the study demonstrate that 25% of participants experience a daily average environmental sound exposure (which can include traffic, machinery, public transport, and so on) that is higher than the WHO recommended limit. Also, nearly 50% of participants now work, or have previously worked, in a loud workplace. As noise exposure has shown an impact on hearing, it’s important to be aware of surroundings. Checking noise levels with the Noise app on Apple Watch can be an effective way to be more aware of sound exposure.
Average weekly headphone exposure for one in 10 participants is higher than the WHO recommended limit. While catchy tunes can be tempting, listeners should consider listening to music and other media at the lowest enjoyable volume.
About 10% of Apple Hearing Study participants have been diagnosed with hearing loss by a professional. Of these, 75% do not use assistive support such as a hearing aid or cochlear implant, even though such devices can help reduce the impacts of hearing loss.
According to data collected using the study’s hearing tests, 20% of participants have hearing loss when compared to WHO standards, and 10% have hearing loss that is consistent with noise exposure.
Nearly 50% of participants haven’t had their hearing tested by a professional in at least 10 years. And 25% of participants experience ringing in their ears a few times a week or more, which could be a sign of hearing damage. Everyone should have their hearing health checked periodically by a professional.
Users across the US are participating in the Apple Hearing Study through the Research app.
On the record
“Hearing loss can impact a person in many ways, and our goal is to drive increased focus on the importance of hearing health across decision makers and the general population,” said Ren Minghui, assistant director-general of the World Health Organization. “We encourage people to take the appropriate steps to protect their hearing and to seek care when needed.”
“One year into the Apple Hearing Study, we’ve generated significant insights into everyday noise exposures and the impacts of those exposures on hearing among our participants. The national scale of this study is unprecedented. We look forward to sharing new scientific findings, as well as informing policy to improve and promote hearing health, as the study progresses,” said Rick Neitzel, associate professor of environmental health sciences at the University of Michigan School of Public Health. “Even during this pandemic, when many people are staying home, we’re still seeing 25 percent of our participants experiencing high environmental sound exposures. The results of this study can improve our understanding of potentially harmful exposures, and help identify ways that people can proactively protect their hearing.”
By 2050, the WHO estimates more than 700 million people globally will experience profound hearing loss. March 3 is designated as World Hearing Day, amplifying a global call to address hearing loss and related issues. Reduced hearing can affect a person’s health and well-being in many ways, such as contributing to reduced communication, feelings of isolation, loneliness, and withdrawal.
