I've always wondered why there's not more R&D going into making power tools quieter, and I wonder if a "sound tax" on products could incentivize it. When selling any item that makes noise, where the noise isn't the intended result of the item (so it doesn't count for, say, speakers), you'd pay a small fee for each db over 70db, or some other level, determined to cause hearing loss, or noise pollution in a somewhat large area.
