I'm not a pro but I don't think most hearing aids produce that much sound. 60 DB sounds get boosted, as well as 30 DB and 80 DB sounds but there is a limit. My UCL (uncomfotable level) is set to around 117 but it would have to be a loud sound to get to that level. Most things come in somewhere between 40 and 105, depending on the frequency. I don't need that much boost in the lower frequencies and there is not that much sound coming in, in the higher frequencies, in human speech. So those high frequencies are getting hit very, very briefly.
