i wondered about that myself, of all the thngs i wouldn't have thought hearing important for a guy who makes loud noises right next to his head for a living... *text deleted*
well that makes sense. thanks!Must admit, I always wondered that too. Apparently however, it's all to do with the hearing test you have when you leave!
If you leave claiming your hearing has deteriorated it can be verified, or indeed refuted, if a set of measurements were taken before you join.
All in all, it's not as daft as it sounds (pardon?).
