New slats make the Golden Gate Bridge sound like a David Lynch movie

I hear this all the time. I was just talking to someone about it. It’s not everyday but it’s frequent. I hear it mostly in the morning and at night.

It’s always the same length, about a second. It’ll come in pulses of 2 or 3 usually. Spread out a few minutes a part. It definitely sounds like an electronic sound. Almost like a sci fi satellite sound but deep in the water far away. Or maybe a far away whale mourning or something.

I just traveled for 3 months and heard it spread across 10 cities.

It’s very weird...

Power companies transmit a signal at certain times of the day through the lines. This controls devices that can switch between day and night mode. My ceiling fans will buzz when it's happening. Sounds almost like the old SMS interference you'd get with FM radio.

This is called Ripple Control, for anyone interested:

Thanks. I was struggling to remember the name.
