I am the aforementioned roommate. I wouldnt worry about your hearing too much until you get close to the 45 level (which i believe is the Navy Max, check with the flight surgeon). Until then they just tell you to wear ear plugs whenever you fly or whenever you are experience higher than normal sound level (lawnmowers, concerts, etc). The beep test is the standard screener but if you are marginal you get to see an audiologist who runs a lot more tests. From what i can remember, the battery includes tests where they ask you to repeat one and two syllable words as they come over the headphones. Then they simulate wind in one ear and give beeps in the other. Another variation of the beep test where you hold the button down until you cant hear the sound anymore and then press when it becomes audible again. There are plenty of ways to make you miserable in that little box. I have a bad habit of falling asleep during those tests which does not help my case. We are all exposed to extraordinary amounts of noise throughout our career so hearing waivers are not that uncommon. Good luck dodging the NAMI whammy, but you should be fine with that hearing loss level. On the other hand, i cant guarantee anything pertaining to the whole in your eardrum. So far the flight surgeons and audiologists have been real understanding. In fact, they have been very helpful in keeping me flying.
