I moved from the city to the beach a little over a year ago, and though the sound of the waves is roughly the same level as the city’s car drone was, it being a natural sound made a huge difference in my sleep quality and overall comfort.
It makes me wonder if the noise profile that cars make could be modified to be less annoying, even if not necessarily less loud.
I would love to hear the crash of the ocean 24x7. The highway noise bothers me because of the echoing nature of it. It's not uni-directional, and it feels like there's always a vehicle coming at me.
My youngest has one more year of high school remaining, but maybe it's time to downsize / find a quieter place after she graduates.
