I have significant hearing loss from a lifetime of firearms, chain saws, motorcycles, etc. and being stupid before hearing protection was a thing. I have the best, top of the line, hearing aids my audiologist sister-in-law can obtain. Don't wear them riding or outside when the wind is blowing. Which it mostly always is in Wyoming. I don't rely on noise from approaching cars. That's what mirrors are for in these days of Teslas.
