Does anyone track their hearing over time to measure effects of different treatments? Something that create an audiogram.
I found this which uses calibration.
I think they are called audiometers. Are there alternatives like using mobile apps? What about buying equipment from AliExpress? How do they compare with online tests?
@AnUser Have you looked at the thins in the threads about tinnitus? Any thoughts on whether those apps that Bryan Johnson uses to “workout/train” his ears have any merit?
I don’t have tinnitus so did not look into it too deep at this point, but if I recall right both companies list key literature and I linked to their web pages / articles about them - and I think I also posted one paper on one of the threads after a question from another forum member.
Online tests may give some indication of high frequency hearing loss and test for difficulties hearing with background noise, but it’s not a substitute for a formal hearing assessment. Professional audiometers are calibrated to produce tones at specific decibel levels. And air conduction, speech, and bone conduction can be compared.
