There is a version that does kssssh kssssh kssssh instead. It’s a lot less obnoxious but not standard yet so only a few trucks have it. It’s much nicer.

I forget where I’ve heard this so sorry in advance for the unsourced claim, but I think white noise is much better for humans to place in space. Higher frequency beeps can bounce around much more than a broad spectrum white noise blast.

Anecdotally they tend to travel much less, and generally be less annoying too. I can hear a beeping truck from ages away in my flat, but not once have I thought “god I wish that kssh kssh would stop”.

This is one noise that I’m absolutely ok with them keeping for safety reasons.

But like is it actually keeping anyone safe? If we disabled that noise across the board, would ppl actually die from being backed into by big trucks?

I'm all for worker safety, but I'd like to see evidence that this beeping is actually an effective measure vs a less annoying sound or the use of back-up cameras??

Seriously, where is the evidence of accidents avoided? Vs other measures?

side note: had to live next to a construction site for 2 years. The beeping started in the morning at sunrise and ran for 12 hours straight.

And I'm wondering what it is like for construction workers; for the noise to provide a safety measure, they would have to pay attention to it. But that means it can't be a constant. Which it is.
