Yes, in fact, there have been scientists investigating the most efficacious algorithms for self-selection of hearing aid amplification since the mid '80s that continues up to today. The modern versions of it are self-adjustment tools like EarMachine ( https://apps.apple.com/us/app/earmachine/id732177210 https://apps.apple.com/us/app/earmachine/id732177210 ) which is the tool I used in my research, or what's called "trainable hearing aids" which have algorithms that observe how you adjust the hearing aid in day-to-day life in different acoustic environments and then try to predict and apply your preferred settings based on the acoustic environment ( https://www.tandfonline.com/doi/full/10.1080/14992027.2016.1219776 https://www.tandfonline.com/doi/full/10.1080/14992027.2016.1... ). These different types of technologies can be (and often are) used together.
