Hearing loss in fire service?

I have hearing loss.(technically) I can’t hear very high frequency’s, but I can hear speech and any other noises. What this disqualify me from becoming a firefighter or working in the fire service. I was disqualified at MEPS when trying to enlist last year.

I have the same problem, women and children's voices. Also, high pitched fire alarms; I can't here it at work when it sounds for no reason. What about hearing aids????
