Music Equalisation as we age or have have hearing loss

At 76, my audiograms suggest that I am losing my upper frequency in line with what might be expected for my age.

I use a MacBook Pro, iPhone 11 Pro, Samsung Smart TV, Apple TV 4K, iPod pros and often Bose QC35 over ear wireless head phones. With the QC35s I can even mow the lawn and listen to music or audio books.

My question, or maybe it is a suggestion or discussion topic, is that with the ability to do our own audiograms via Apple supported apps such as Mimi Hearing, is there any way I can use the results of an audiogram to adjust the sound volume (at the different frequencies) of my iPhone?
