The results of the test will automatically be used to adjust the sounds and compensate for your hearing loss. This applies to both your general listening to ambient sound like speech and your environment, as well as streamed audio when listening to music, videos, podcasts, etc., while you wear your AirPods Pro 2 earbuds.
Audiologist's note: Be safe! Hearing loss is sometimes related to other serious health problems. The Mayo Clinic and Northwestern University have developed the Consumer Ear Disease Risk Assessment (CEDRA) questionnaire, which gives you a risk score to help you determine whether to see a physician or audiologist before purchasing hearing aids to rule out other ear diseases.
Step #1 (Best way): Upload an audiogram from a professional
Although most people will use Apple's Hearing Test, the most accurate way to tune your AirPods Pro 2 earbuds is to obtain a hearing test and audiogram from a licensed hearing care provider. The provider will test your hearing in a soundproof booth with calibrated audiometric equipment and check for wax buildup and any other potential problems. Some providers may offer this test for free (although they may also try to sell you a hearing aid), while others will charge for the service.
Once you receive a copy of your audiogram from them (which they're required to do), you can photograph it using the iPhone camera. You can enter the information from the audiogram directly into your Apple Health app by tapping:
Hearing—> Hearing Test –> Add Test (blue text at the top right of the screen).
This will take you to the Add Your Hearing Test Results screen, which allows you to Add Manually the audiogram data or Scan with Camera your audiogram.
Bonus: Get your Hearing Number!
You can use either Apple's Hearing Test or an audiogram from a hearing care provider to calculate your Hearing Number at the Johns Hopkins website. This is a good way to monitor your hearing status through the years. (Here's more information about why you should know your Hearing Number.)
Step #2: Turn on Hearing Aid Mode
After you get the results from your hearing test or have entered data from your audiogram and hearing test results, you'll see the Hearing Test Results screen. There will be recommendations on what to do next, and if warranted, you can select the option Learn About Hearing Aid at the bottom of the screen.
This will bring you through some screens that inform you about using the AirPods as OTC hearing aids, until you see the option Turn on Hearing Aid. Once this is pressed, you're good to go; you can use the AirPods Pro 2 as an OTC hearing aid, with the devices tailored to your individual hearing loss for both listening to conversations and listening to music and audio on your phone.
Step #3: Adjust the sound to your personal preferences
Once you've completed Step #2, go back to the AirPods main control screen, tap on Hearing Assistance, and then use the Adjustments screen to further fine-tune the sound of the AirPods Pro 2 to your own liking.
