As a wife of a hard of hearing husband I can relate to this. I really got use to him not fully hearing me and I would mumble grumble under my breath. He got hearing aids (great ones from Costco of all places)in January and I'm in big trouble now. He can hear my mumble grumbles. Last week he got a remote control for the hearing aids--I didn't know such a thing exists, but on the aid itself there is only several volume settings, but with the remote it has a slider on it and it gives a better range to choose from. He is a happy listener now.
