Last summer, the local power company buried lines in my neighborhood. They've also been on top of clearing trees away from long-distance transmission lines and making upgrades along the way. That doesn't prevent the occasional blip from something in the wider power network, or damage to those long-range lines from various causes despite their efforts.
When I was growing up in the late 80s and early 90s, my parents didn't have a TV on 24/7. Terrestrial radio was still a common source of news and entertainment, but it wasn't always on. Ar first, we lived on a little-used rural road with only occasional farm noise from the neighbor. Then we moved next to a highway, where the hum of engines and tires was a background hum at all times. But I did grow up playing outside, or with non-electronic toys and books inside. Times have changed, and my niece and nephew have had tablets since they were toddlers, always with electronic background noise.
