Can an Airline pilot use audible range aid ?
Answers: I really don't think audible range loss at 8kHz only should affect your cleverness to be a pilot. It depends on your licensing board merely go through your trialling and hope for the best. However, once you are aware that you have audible range loss you should be extra vigilant about wearing your audible range protection whenever you are around loud noise - mowing the grassland, at concerts, using powertools etc. Especially if you do become a pilot you want to keep what you enjoy.
To answer your a question give or take a few a hearing aid. A audible range aid will not help your audible range loss at 8kHz. Hearing aids only amplify out to 4 kHz sometimes 6 kHz so it would be a consume of your money. Pilots may be able to wear audible range aids under their headset, but it would be difficult as you often seize a whistling nouns out of hearing aids when they are covered up. However, the newer technology is improving.
Depends on the requirements of your local aviation licensing board. 8Khz is outside of the speech inventory, and if it is unilateral, typically it would not require a hearing aid -- contained by fact, most HAs with the sole purpose aid up to 6Khz. Therefore I would think that it would not be an exclusion for a pilot's license, but cannot endow with you a definitive opinion on that since it depends on YOUR license board.
Typically this kind of loss results from clatter exposure, so be more careful next to loud music and using headphones beside power tools.
