I did the test twice out of curiosity. I have known hearing loss and tinnitus, a unfortunate family inheritance, and have been wearing hearing aids full time for about 12 years. I did one test with on the ear headphones, another with wired Apple earbuds. Not exactly the same, but the outcome was the same and consistent enough with results of professional hearing tests that I can recommend MimiHearingTest for screening purposes. Since unaided hearing loss is a factor in some many areas, including social isolation, loss of the ability to distinguish words, and even dementia, I recommend that anyone suspecting hearing loss follow up. Addressing the problem is far better than suffering and the level of daily energy it takes to function when you do not hear well. Modern hearing aids are marvels of technology and improve all the time. My only issue was understanding the very clear instructions on “the button”, holding while hearing a sound and releasing when it stops, and the portrait only orientation on the ipad. My phone does not have a 3.5 connector, so had to use the ipad. Linking to Apple Health had to be done on the phone, and required an account with Mimi, but eventually I was able to link it, and see the results in Health.
