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

#242This is very similar to an Aeolian Harp, also known as a wind harp. https://en.wikipedia.org/wiki/Aeolian_harp https://www.youtube.com/watch?v=CtzSm76ppS4 They are pretty cool art installations. The Golden Gate bridge may now be the largest such installation ever built!
Ok, I'm on board here. This is really cool. Yes, it cannot be a 24/7 thing, the harp/bridge is too loud. Also, putting resonances into a suspension bridge is likely to be unsafe. That said, like the chiming of church bells in a village, it may be used selectively. I can imagine some Burners quickly putting up an adjustable mechanism to have the bridge sing/chime. Something that can point into the wind correctly (to s…
There is already enough noise pollution in the world. We don’t need noise graffiti that indefinitely blasts sound 24/7, even after the perpetrator is long gone.
If you really want to help build a dystopia, you’d probably have a bright future in advertising. Apparently electric car noises were less about safety than branding.
Some of the car manufacturers wanted their cars to blast sound logos all the time, but they were afraid the first movers would be lined up against the wall and shot.
Electric cars were the perfect excuse to do it anyway and blame regulators, so their lobbyists made it happen in the name of safety.

#243There is a wind harp in South San Francisco that drives me nuts. It just sounds like wind passing through power lines, a low hum.

#244I’m curious if there can be an impact on the wildlife out here. Animals don’t understand what the noise is, so can it disorient them in some way that could have a harmful effect?
I’m sure the constant noise will negatively impact predators, at the very least.

Sound travels, what, 30 centimeters a ms? Bluetooth/wifi is good for at least a few meters, and should have latency of around a ms. Should be pretty easy to synchronize via that.
You need to maintain millisecond sync while the devices are widely separated, possibly for hours. Cell phone clocks are not millisecond-accurate over hours. The idea is that a group of people all download the app and walk or drive around the area of interest collecting time-stamped audio and sending it to a server. Amusingly, data collection would be easier with analog technology. Get some VHS walkie-talkies, and, at…
I think you’re missing how easy it is to do these days.
It’s pretty easy to do with NTP synced devices. I’m lucky enough to have a fleet of devices sync with GPS and the PPS signal. It’s pretty amazing to/fun to do latency tests, you grab a time stamp and ship it to far side and time stamp the arrival. Voila single direction latency measurements.

#246They finally found a way to reduce the cost of real estate in SFO! Seriously, you have to wonder how someone can actually think this is OK when it can be heard from far away at all times and people crossing it are reporting it to be unbearably loud.
My prediction is this will be added to the long history of engineering disasters. It's OK, this is how we learn.
Here's another video I found:

#247Has anyone gone out there with a sound level meter? If it's that loud, won't it drown out sirens or car horns??

#248This sounds exactly like the audio synthesis I did for a recent generative sound app. I didn't know too much so a very high q band pass filter over brown noise did the trick. Do that over several voices (not necessarily harmonic) and you get something similar. Check it out: https://apps.apple.com/us/app/night-shapes/id1490540845

Sound perception is extremely complex and nuanced. The brain can tune out both specific frequencies and baseline shift while the ears are more sensitive to some frequencies over others. This sound is fairly pure and doesn’t really overlap with other artificially created sounds you’d encounter about the city, but I’m not an expert!

Pretty much the only good thing about the lockdown was the massive reduction in sound levels in London. Just off Old Kent Road which means traffic noise dropped, plane noise disappeared[1], general hubbub of the feral children vanished, no late night parties at the community centre, etc. It was as close to blissful as I've encountered in London. [1] Normally one every 5-10 minutes from 0500 to 23000 since we're on He…
Lots of good things about the lockdown from the aspect of peace, quiet, nature, clean air, reduced light pollution, and more. It just comes at a cost that society isn’t willing to bear.
