I tried making a spectrogram: https://twitter.com/nibot/status/1269347206445756416 I tried using baudline[1] (a 20-year-old program!) but it didn't work out-of-the-box on my current Linux installation. Instead I found something called Sonic Visualizer[2], which, while not real-time, worked out of the box. Using Pulse Audio 'pavucontrol' it was easy to configure Sonic Visualizer to use as its input the 'monitor' chann…

every musician ever: A440 PROVEN BY THE BRIDGE

In tuning systems what one really cares about is the ratio between pitches, not the frequency of a specific note. You could have A=440 and tune to just intonation and that would sound different from A=440 and 12 tone equal-temperament.

I honestly think this is awesome and beautiful, though I might feel differently if I lived nearby just because of how relentless it is. I remember years ago I had the idea that if you could design construction equipment to rotate/oscillate/whatever at frequencies that were harmonic with each other, construction noise would become musical, almost like a very loud set of wind chimes.

Yea I do. Our neighborhood on nextdoor is pretty unhappy...

this is fascinating! i wonder how long it will take them to do something about it? seeing the video, i almost wish they'd keep it, but i don't live nearby, so... i found a couple more video examples of accidental acoustic wind effects in architecture -- but it looks like these aren't as ever-present and loud as the Golden Gate Bridge is right now.

Yea, it doesn’t sound musical. Just like construction is happening every time it’s windy

There should be an app for this. To get direction and location, you need acoustic samples from multiple widely-spaced locations, all synchronized. Human ears are not wide enough apart to directionalize low frequencies, but with a baseline of tens or hundreds of meters from separate cell phones, it's not hard. Run a correlator, line up the samples, compute the hyperbolas of constant time offset, (like GPS and LORAN) a…

Wouldn't work in this case though - the sound doesn't contain high enough frequencies to correlate well.

According to following, engineers knew this sound would happen during high winds from the west. https://www.theguardian.com/us-news/2020/jun/06/golden-gate-...

Here's a video from the company that built the new handrail: https://www.youtube.com/watch?v=N-XCbsyRENI From your article: "The wind retrofit project is designed to make the Bridge more aerodynamic under high wind conditions and is necessary to ensure the safety and structural integrity of the Bridge for generations to come,” Cosulich-Schwartz said." This statement doesn't agree with the video's rationale for updati…

I'm kinda curious what the rational of the net is. If you're determined to jump off the bridge, you can jump off the net too.

Suicide attempt survivors often say they regret their choice to attempt suicide. Giving them a second chance makes sense in this context.

My parents lived up that way, and the amount of NIMBY-ism regarding offshore turbines is staggering. I suspect you may be right, and people just latched onto whatever claim got the turbines shut down.

It is also possible that they generate the sound of the same frequency, but coming from multiple sources it can compound in some areas to be louder than elsewhere - and those areas could change with the direction of the wind. This is purely speculation from my side of course, as I've never been there.

No, it's a pretty safe bet that any of these complaints about wind turbines is just NIMBYism. It happens every single time.

I'm just glad they identified the source of the hum, many people are impacted for years by unexplainable sounds, and it is maddening. It took me and my neighbours a month to find the source of a hum that was resonating with our windows. It was torture, with midnight walks and lurking around potential sources, mapping nearby industrial sites, and questioning our sanity, while our windows were vibrating without a stop.…

Two unrelated anecdotes: 1. A few years ago I spent some time in Falmouth, MA and there was an ongoing battle over newly installed wind turbines. The humming sound was getting to people, including to the point where they were getting headaches. Some people heard it and others didn't. The locals were going to war with the initiative. This article reminded me of that and I checked in on the ordeal. Looks like they shut…

Wind turbines do not make that kind of noise. It's always, every single time, people angry about their view or any kind of change at all.

Every single time.

This sounds so beautiful and desolate, reminding me of a combination of the first two tracks from Aphex Twin's Selected Ambient Works Vol 2, disc 2, in particular "Blue Calx" and "Parallel Stripes" starting from 40 seconds. [0] Thank you for sharing. [0] https://www.youtube.com/watch?v=FXBAU8HsAqk

Berlin has some absolutely beautiful church bells. The overtones and reverb from all the walls are so chilling, it makes you feel like you're inside the bells or something. I recorded one of them: https://sndup.net/2h7t/St+Joseph+Kirche.m4a

Guy from Berlin here. Isn't this how church bells are supposed to sound? Do they sound different in other places?

I bet they don’t love the sound of your complaining either. Both human. Both entitled to exist.

I bet they aren't exactly happy with their day-to-day either. It's just we are somehow normalizing and glorifying suffering instead of encouraging people to walk an extra mile to get out of it.

Maybe they should walk an extra mile away from his windows.
