Does anyone know why? Is there a way around this by reducing SPL/MPO? It goes on to say that hearing at 0db overamplifys(too loud) you and results in distortion. If someone has 70db HL and a 0db sound is amplified to 70db, that person should just barely hear a 0db sound. How can it be too loud? As for a 30db sound, don’t give 70db gain, use compression so a 30db sound is only getting 55db gain, but a 0db sound gets the full 70db gain.
If someone can’t benefit from hearing at 0db, would 5db or 10db be far easier to be able to tolerate? Also why aren’t maximum gains always used in severe-profound hearing losses so you can hear aided at 25db or better so you understand the most speech and hear the most sounds?
