I suspect one of the first questions an audiologist or an AME popping by might ask is where were these hearing tests done? FIWI my measured losses (mainly in the right ear due to a mispent youth) have varied over the years due to what I suspect were "experimental error" ( e.g.quality of headset, noise exterior to the exam facilities....).
In any event I'd second the advice and wishes given by the above posters..
