This is a serious question and something ive been wondering for a while now. If a hearing aid gives you as much gain as your hearing loss, does it completely cancel your loss and therefore result in you being aided to 0db? Say someone has 70db hearing loss and wears a hearing aid programmed for 70db gain(which may not even be the max gain the HA is capable of!) would he have an aided score of 0db? If not, what could be the reasons?
