What is the Apple Hearing Study?
The Apple Hearing Study is a first of its kind research study to collect sound exposure data over time and advance the understanding of how sound levels can impact your hearing.
Why is this study being done and why should I participate?
Your hearing could be impacted over time by exposure to certain sound levels. This study aims to collect headphone and environmental sound exposure data over time, and determine how it impacts your hearing health, stress levels and cardiovascular health. This will ultimately help develop new products to optimize your hearing experience and reduce the likelihood of hearing loss.
How does this study work?
You can participate in this study with your iPhone and the Apple Research app. The study will ask you to:
- Provide your consent to collect data from your iPhone and Apple Watch (if applicable), such as your Health app data, sound exposure data, and other Apple Research app related data.
- Complete occasional, short surveys about your demographic, medical history, and headphone and environmental sound exposure.
- Complete a pure-tone hearing test task and a second listening test within the Apple Research app.

I wear a cochlear, middle ear, or direct bone conduction implant, can I participate?
Yes, this information will be captured as part of your medical history profile when you answer the survey questions. You will be able to complete the study surveys, and to contribute noise levels measured by your Apple Watch (if you have one). We will not be able to evaluate your exposure to sounds from music, games, and other media that you stream to your cochlear implant, and you will not be able to complete the tone exercise task.
I have hearing aids connected to my iPhone by Bluetooth. Can I participate?
Yes, you can participate. You will be able to complete the study surveys and tone exercise task, and to contribute noise levels measured by your Apple Watch (if you have one). You can also take the tone exercise if you remove your hearing aids and use your AirPods/EarPods. We will not be able to evaluate your exposure to sounds from music, games, and other media that you stream to your hearing aids.
Is this study available in languages other than English?
The study is currently only available in English.
Can I use a friend or family member’s iPhone to participate?
No, you can only use your own iPhone with your own iCloud account. This is to ensure data integrity.
What headphones are required to participate in the study?
Any headphones can be used to measure your sound levels in the study. The tone exercise task requires the use of Apple AirPods or EarPods (which you received when you purchased your iPhone), but if you do not have AirPods and EarPods you can still participate in all other aspects of the study.
Do I need an Apple Watch to participate in this study?
No, an Apple Watch is not required to participate in this study.
Can I enroll if I am already participating in another research study?
How do I enroll in this study?
You will need to download the Apple Research app from the App Store and install it on your iPhone. In the Research app, you’ll find the studies you can enroll in. You will need to select the Apple Hearing Study and go through the introduction and consent process.
What will I be expected to do if I participate?
You will be asked to provide your permission to collect your headphone and environment (if applicable) sound exposure data. You will control exactly what data you share. Every six months, you will be asked to complete a short survey regarding your hearing health. Apple Watch is not required for this study, but if you own an Apple Watch, wear it as much as possible to enhance your contribution to the study.
Are AirPods or EarPods required to participate in this study?
No. You do not need AirPods or EarPods (which you received when you purchased your iPhone) to measure your sound levels as part of this study. The tone exercise task of the study can only be completed with Apple AirPods or Earpods, but if you do not have AirPods or Earpods you can still participate in all other aspects of the study.
Why are AirPods or EarPods required for the Tone Exercise and other listening tasks?
The tone exercise task is the only task in the study that requires use of AirPods or EarPods as these devices are calibrated to perform the test. If you do not have AirPods or EarPods, you can end the task by pressing cancel and exiting the task.
I notice on the baseline survey you ask about hours spent using headphones. Does
this include time spent using headphones to talk on the phone, or only headphones
used to listen to music, games, and other media?
We are only interested in your use of headphones for things other than talking on the telephone. Your use of the telephone is not monitored in any way as part of this study.
I just enrolled and completed the study onboarding process and initial survey, but
I don’t have any current tasks in the Research App. Is that normal?
After you complete the onboarding process and the initial survey, your next scheduled task will not become available for 3 months. If you have an Apple Watch, it is possible that you may be prompted to complete a triggered task before 3 months based on your environmental sound level. It is also possible that you may be prompted to complete a triggered task before 3 months based on your headphone audio levels.
What is the Noise app on my Apple Watch?
With the Noise app on Apple Watch Series 4 or later, you can enable Noise notifications to alert you when your Apple Watch identifies sound levels in your environment that could affect your hearing. Visit the support page to learn more about Noise notifications on your Apple Watch.
What happens if I start wearing a cochlear, middle ear, or direct bone conduction
implant during the study?
The Apple Hearing study will have annual surveys questions that will capture any changes to your hearing.
