MORE ON HEARING AIDS
I am writing about your hearing aids for pilots article in the March 2021 issue of Aviation Consumer magazine.
I have what I think is fairly typical age-related hearing loss, which kicks in at about 2 kHz, and is about 40 or more dB down by about 4 kHz. (You can get tested for free by Costco, incidentally, which can be very helpful to know what your individual loss is.)
