I can identify the differences in environmental sounds with my hearing aid. It all depends on each individual.
I drive a car and actually sometimes I miss an emergency sirens until the last moment.
Once I created an embarrassing moment for myself while driving to pick up
my daughter from school.
We were waiting for the left turn light, it finally came on but the lady before me didn't budge.
After good 10 seconds or more, I started honking at her rather angrily
as I was rather late for a pick up.
If you are late for a pick you know how awful traffic at the school can get,
you get no parking space, long line up, and all. at this particular school also turning left into the school lot was a murder.
anyhoo, I was honking at her thinking she wasn't paying attention or something and knowing the left turn light only last so long
when all of a sudden finally an ER vehicle pops up from the very left side we were supposed to turn in!, ughhhhh
to make matters worse !!!! I had to follow the lady to the very end !! -
turns out, she was picking up some student from the very same school - how embarrassing is that !?
Of course SHE could hear the sirens way before they were visible, I didn't.
So, yeah, I believe that could come handy and increase road safety.
Imagine, I would have proceeded with the left turn straight into a speeding ER truck, hmm.
