New Guardrail Causes Golden Gate Bridge to 'Sing' in High Wind
ฝัง

- High winds on Friday produced tones that are the side effect of a handrail retrofit designed to make the span more aerodynamic on gusty days. Wilson Walker reports. (6-6-20)
When error occurred and they cannot fix it, they call it “a feature”
There are no bugs. Only features. That also applies to insects and cars...
Ah yes, the Bethesda Approach™
This is a well known principle of software marketing
LOL
Oh Man I LITERALLY just UPLOADED a Golden Gate Bridge video of me walking on it. You should definitely check it out because you can feel the HISTORY. If you don't like the video I'll give you $5 just for your time. You will not REGRET IT!
Maybe home prices will finally go down thanks to this "feature".
When they hired a newly engineer that got his credentials online. I already got tired of hearing the humming noise for 3 minutes, sucks for the people who have to bear with this for years to come.
Ok that would annoy me, if I did that someone would say it’s noise pollution
That bridge has always sung death notes, attracting suicides
Damn dude lol
Upon Wrath I mean he’s not wrong
Lmao. Damn
Dang now I’m sad. 😂
maybe they will find somewhere else to jump now
Bad. No. Stop. I am not interested in hearing this every day.
Cover your ears
@Mr Jones I've heard it from 8th ave and Geary several nights in row with not-that-high-wind.
No like?
@Mr Jones yeah well we get lots of wind lol
@Mr Jones then you know.san Jose in the 2000s I fogetth year but our wind was so bad I couldn't really walk..lol..it was to strong to walk in it was no joke
We ought have someone reverse engineer the rails so that they will sing to the tune of I Left My Heart In San Francisco or better yet The Sound Of Silence.
Why do they need to add a feature to withstand winds, the bridge has been there longer than any of us have been alive.
"To achieve that sustained auuuuh" 🎵🎶🎶🎚🎙🧔
Now we can finally hear it’s voice! They taught bridge to sing, maybe one day they will teach it to speak.....
Wow, that could mean that the bridge is compromised.
Clearly it is noise pollution. The frequency and resonance of the sound can actually damage the bridge over time, kind of like a crystal wine glass if you wet your finger and run it around the upper edge, it will sing, and if you do that long enough it can and will shatter the glass. I know the bridge is not made of glass, but it can cause damage.
If it is expected ‘feature’, shouldn’t it be published as part of the design, how come media not aware or do some research, probably corruption is now the norm in SF, no one really hold anyone accountable. Tax the working class to death, legalized corruption next.
That new “feature” will cause something disastrous.
Distant trumpets or shofars, calling an evil area to repentance.
There’s a myth saying on that bridge there’s a certain jump point which take you to another demension into a mythical place
Each tower has a fog horn that helps 🚢 in foggy weather Navigate into the bay. I hope the hum doesn't interfere.
Sound is made from vibrations right?
I could hear it in the TL @ Hyde and O’Farell early in the morning before all the traffic.
The softer you sing, the louder you're heard....don't jump today it's too windy.
that durn wind can ruin your whole free fall experience until the moment of impact
Before you know it, the karens will be raising holy hell about 'that noisy damn bridge'.
Also...it sounds a lot nicer than that infamous shrieking kid on the airplane.
I don’t remember advance notification of the noise problem during design approval, environmental review, etc., for the Golden Gate’s new railings. Did they tell us they were putting up something so annoyingly noisy? It’s claimed that the experts knew in advance that this noise would be the result of this railing installation. I feel that we were not allowed to consent to something which causes an intense irritation for so many.
It sounds eerie and kind of cool. But isn’t it going to drive people insane?! And it’s not a feature don’t even try
That’s some war of the worlds stuff
3:13 Did this dude really imitate the sound with his voice....
yes, the bridge and I, when I produce wind, it can be heard for miles.
It whispers: Louise.
Does anybody realize the vibrations that are the sound are wearing joints and fatiguing metals. It could be as easy a fix as bolting decorative weights to the middle of the sound producing bars to dampen their frequency response.
Maybe even weaving some type of material through the slats?
When you how bad engineers and they didn't take into account the wind. It is so fun and games until a lawsuit comes. Lol
Yeah, we totally knew it was gonna sound like a portal to hell. It’s a “feature”.
😩😂
EXACTLY!
@jattatheart111 Bay area is one of the best places on Earth
Lmfao
Not a portal to hell, but to The Heavens “Golden Gate”
I prefer my bridges silent
Silence is Golden🌉🌉
Oo nice
Lol
Much
The GGB has never silent.
A feature, just like a neighbor with a barking dog that goes all day and night.
Lol foreal, like I doubt the people who's homes vibrate thinks is a pretty song
My dog has that feature! Anyone else order theirs with that too?
Ya but you can't feed it poison.
Ok boomer
That noise is gonna make people in the Bay Area even nuttier than they already are.
Seriously, folks, this is called noise pollution and can really wear on people. Shame on the engineers who "anticipated this" and did nothing to abate it.
I'm autistic, this would make me pound my head against a wall.
I live in the bay area and this is the first time ive ever heard this!
Or we just take it in stride - we're easy going folks who like our eccentric bridge.
Purge siren
That’s true
Hope they kept the old rails...theyre gonna need em after the first lawsuits start rolling in.
karens are gona love it when the new rails are in place
Not an option. The rails were replaced in order to lower wind drag to compensate for the heightened wind drag of the new anti-suicide nets. They can't go back unless they remove the nets and let the suicides resume. Imagine the much bigger lawsuits if they did *that*.
They'll probably come up with some kind of vibration-dampening bolt liner or something that'll reduce the volume.
@@jv-lk7bc How do you get sued for someone else's actions? This scares me...
Its It's literally a giant bridge long Harmonica. 🤣
It's the wailing of all the souls who have committed suicide by jumping over the years
"This is a once in a lifetime 'HOLY SHIT!' idea.... and the water under the Golden Gate is freezing cold"
Or its not over till...
The bridge will fall soon! Be careful!
Alex Ved nigga
Alex Ved it's not, it's a magnetic field or resonance. Earths magnetic field is weakening allowing cosmic rays to effect the metal. Think about this all that construction didn't just get put up overnight and the wind didn't just start blowing. Expect a very big earthquake nearby get ready be prepared
That’s going to be obnoxious to anyone or animals living near this.
Awww poor animals 🤷♂️
I bet the animals are gonna riot
CHEE- RIOS burn it down with kerosene
do you recall the song open the Golddend gate my father use sing that song before he passed away in 2015
I completely agree. I think about how the vibrations can affect life in the ocean.
That guy is way too proud of the noise. It's a bridge, not an art piece. "Cool" and "Different" isn't the point. Sound has been used as a method of torture for POWs. It causes stress and sleep deprivation which in itself is a form of torture. Audiologists have long discovered that prolong exposure to low pitch hums can cause hearing loss. You can't control the wind so you can't control the duration of the hum from bridge. You can't control the time is occurs like during sleep hours, and you can't control the wind speed so there's no guarantee it will be quieter at night. In fact wind tends to stronger at night.
ok boomer
I'm pretty sure they didnt expected this. So they're using an excuse like it was expected after the fact they realized the made a mistake. Who makes a bridge that creates noise pollution?
@@sargebeats For a millenial U put a lot of thought into your comment, impressive 😃👍
He’s correct!

already here
sound of trumpet. its the sound of metals, mothership is right on west coast.
Black people??
Wakanda people
That would be kinda cool if it attracted them just from the sound
It's like a giant harmonica.

@@Dweller415 It actually is.
Bruh are the engineers not watching SpongeBob? They literally made a whole episode on this phenomenon
Really? Cool.
A feature. Like at a theater? Like a car option? They admit they knew this would occur. This makes them legally culpable and liable
better than being legally culpable and liable for the suicides.
@@jv-lk7bc Yeah now people will just shoot themselves to get the creepy humming to stop!
@@jv-lk7bc I guess I don't get HOW the 🌉 is responsible for suicides?? Never could figure that one out. The bridge didn't force the people to jump
Sounds ominous. 🌉🎶😕
i would rather listen to that than talor swift
"Frustration has been mounting for nearly a year. Sleep has been disrupted. The constant background hum has become an unwanted way of life in neighborhoods as far away as Daly City"
You know that the silicon valley takeover of San Francisco is complete when bugs are being lauded as features.
user: "This fails when used. Is this a bug or a feature?"
Ubisoft: "Yes"
That can't be good for the wild life in the area.its horrible. Not singing.
Oh god. Go hug a tree. You'll be alright
@@salmonslayer707 😂
Oh yeah i bet the wildlife will die due to having to hear
Actually sound waves affect birds bats other species....dolphins, Wales etc
michelle belle yea that's why I call bs on the news story, it's a magnetic field or resonance. Earths magnetic field is weakening allowing cosmic rays to effect the metal. Think about this all that construction didn't just get put up overnight and the wind didn't just start blowing. Expect a very big earthquake nearby.
That's annoying!
Silence is Golden
It is a engineer error, not NEW feature to old bridge! Fix it!!!
Couldn’t help but laugh at mr salesman for the “new and improved aerodynamics upgraded handrail” … “oh it’s a new feature of the bridge” what a load of BS and waste of money. Always someone selling some garbage for a construction contract.
The bridge is 83 years old! It’s obviously hasn’t been very resilient to wind for the last 83 years, let’s add a hand rail that allows more wind to pass through and makes a noise heard audible for miles then lets call it a feature! It was really necessary. This is what happens when our school system has gone to hell and we give everyone an A for effort and everyone makes the team.
That frequency vibrating the bridge will probably bring it down in a catastrophic collapse eventually.
Harmonics can do weird things to objects!
If anyone has watched the documentary “The Bridge” you can understand how eerie this sound and view can be. Rest In Peace to all of the people that have lost their lives here.
when that bridge collapses they will blame it on that "feature"
I work on the bridge. It starts humming at around 20 to 30 ish mph.
Positive or negative feelings towards the new sound since you work on it? It kinda reminds me of a meditation singing bowl.
So whn do U supoze it will collapze???
God bless you
That's gotta be an interesting gig! Are they still painting it constantly? We found giant chips of many paint layers on the Marin side. There was no "humming" sound before was there? Weird!
I totaly forgot about this comment. I dont have feelings towards it. It's from the new handrail we put in. I'm sure there will be a fix. Its loud, and it hurts the ears up close. We put new handrail in to help with the aerodynamics from adding a suicide barrier... as far as painting it constantly, that's a b.s. rumor. It is NOT painted end to end, constantly. No, there was no humming sounds before..
I give it about a year until they reverse it all.
Well, I wonder if they have
yea i wonder
That's really annoying. People who like it don't live near it. If they do, will go crazy.
This bridge is going to become the next 9/11 the end is near get right with Jesus Christ before you die in your sins.
It's literally a giant harmonica.
A feature? , maybe look into how hypnotic that will become once everyone is used to hearing it. It also sounds eerily like a Shofar being blown..prophetic end times horn maybe?
It may be handrails making the the sound, but ignoring it should not be an option. If the rails are vibrating, they are damaging the main structure, slowly. If you want to see what happens to a bridge that vibrates and more in the wind, should look up galloping gertie
It's just the new railings that are causing the noise. The bridge deck itself is not vibrating.
Not necessarily true on damage. It depends on the frequency VS how the bridge takes the vibration. Given that cars and trucks cross it... I'd say it's not likely. As for galloping gertie...
The physics are totally different but related to why they changed the rails. Gertie had solid guardrails which the wind could grab wholesale and directly twist the structure of the bridge. The bridge's response to that wind was such that it was the resonant frequency of the entire structure.
The humming rails on this bridge, if even possible, would cause damage in a different mode. The humming would just loosen something or cause some sort of minute, gradually propagating fracture damage over time... But again that's assuming it's even possible which I highly doubt. Not much energy's going into the bridge that way, I bet. Park a truck with a concert stack or two on the bridge and I bet you could get the same volume out of it.
Many catastrophic bridge failures over the years were caused by what looked to be non essential issues. The Florida walkway which collapsed onto several vehicle's, killing the drivers, I-35W Mississippi bridge which many ignored until it was too late. Bringing a truck blaring the speakers for a day at same frequency is not the same as a entire rail that expands the length of the bridge. The Golden Gate bridge was never designed to deal with the railings that were recently added. The vibration may seem to be absorbed, but somewhere parts unseen will most likely become loose, form cracks. Hyatt Regency walkway collapse which injured and killed many was caused by several factors, vibration, weight, illegal changes to design which the owners tried covering up, but was discovered when one very good investigator who was not really part of the investigation found where the damaged walkway parts where being kept hidden. If something does happen to the Golden Gate Bridge due to the new handrail vibrations being given off daily, it's most likely going to happen many years from now, and if so, let's just hope when it is discovered, it's not after a catastrophic event and just an expensive repair with a lesson learned.
Wonder what all our bridges , highways,, trains will look like in the future. They are old at the end of their life span and don't last forever. Are there even plans to build new ones Perhaps? We are so far behind. Get crews out there. Teach people a trade and pay them well. my great Uncle built the huge transmission towers on the east coast, PA, in the 1960s and 70s. Hard work.
Perhaps new technology and materials can be used to build them faster, better and cheaper. Those " shovel ready" jobs from the 2008 recession sure didn't get going too fast. I drove cross country 4 times from 2015, 2018 and saw whole huge new freeway projects in fly over states where there were 2 trucks and 5 guys. Get a crew of 125 people on it and it can be done.
You can hardly go south from NYC through DC to north carolina on i95. The Jersey turnpike is narrow in places and crowded and people drive 90 mph up your butt. Only 2 lanes south out of DC in each direction and it is backed up all day every day. Needs to be expanded north and south.. I hope there will be repairs to all the failing bridges, highways and local roads. We need high speed train infrastructure too. None of the tracks in the N.E. can handle fast trains. Current tracks are narrow and near population, homes, etc. The tunnels old and small. Wish we could filter the trash and chemicals from storm water run off before it gets to rivers and oceans. So much we can do, but seems nothing gets done or takes 30 years!
It's not a bug; it's a feature.
( ... a feature, I might add, that is tapping into the bridge's resonant frequency. It's oscillating, not singing, and it will soon prove fatal to the structure's integrity if not corrected. The oscillation is forcing the entire bridge to compensate by vibrating cables, like strings of a guitar. The sound you hear is probably the road deck and trusses acting as a sound box, amplifying the sound. This error will ultimately cost millions to repair before it causes irreparable damage. See Tacoma Narrows Bridge or HuMen Bridge for further reference.)
People can sound like they know what they are talking about on the internet but actually know jack shit....like this comment for example
Someone must've read the wikipedia page on resonance and bridge failures but isn't an actual structural engineer :)
Not necesserally, it could be really just the wind being shattered arround the newer railings, like any blowing instrument, the air is vibrating not the instrument itself
Don't tinker with the design; leave it along.
@Kristin Marie Yes but now you have created something which is going to wear on the people around the bridge area. There had to be other ways to do this why wasnt one of those chosen.
@@valcan321 Cost is usually the culprit
Lmao jokes on you. They are fixing it
A sound completely in accordance with the times we are about to live.
Close to the sound of an air raid siren!
Prophecy and omens are everywhere. No need to look in a book. All of reality reflects the rest.
This is the sort of thing that would be turned into a legend in a post apocalyptic world, a la horizon zero dawn.
Like, "the crimson Bridge sings with the souls of the old world, warning you to stay away from the invisible poison that fills the air beyond its span"
(the implication being that LA gets nuked)
Sounds like some shit from a Terry Brooks novel.
I much prefer the implication in this post apocalyptic world that LA suddenly moved 350 miles south just to the other side of the golden gate.
I live in Fresno and I can hear the humming from my bedroom. Nvm my girlfriend left her vibrator on.
☠🤣👏👌
If you don’t know how to turn it off put the ting in your hole don’t waste batteries 😬
Makes you think of the "Galloping Gertie Bridge" in Tacoma. After they fixed the guard rails it didn't sway anymore. It swayed radically and collapsed under the pressure of the wind. But like I said they figured out it needed the guard rails to be a certain way.
To add more detail to this comment, the bridge used solid girders on either side, giving it that sleek look. These girders caused the bridge to experience resonance from vortex shedding. This is seen in the vertical undulations. This resonance wasn't why it failed though. On the day of its collapsed, a different oscillation started 45 minutes before collapsing. Instead of moving vertically, it moved in a twisting motion. This again may possibly have been caused by the solid girders. The phenomenon that caused this was possibly aeroelastic flutter, which is different from resonance from vortex shedding.
I'm not gonna explain how these phenomenon work since this would make this comment too long, but in short the flutter caused too much stress in the suspension cables and the bridge collapsed. Thankfully the only casualty was a dog trapped in a car stuck on the bridge. The bridge was the 3rd longest at the time, and took awhile to build, it collapsed only a few months after completion.
Thankfully the golden gate bridge doesn't have solid girders so it's probably unlikely for the bridge to suffer the same fate as the old tacoma narrows bridge(galloping girdie)
Take this with a pinch of salt though, I am not a professional.
Its really the UFOs
2020 is the weirdest year ever.

It’s the seventh and last trumpet.
Can you enumerate the previous six?
Look at this dude busting out the Brian Eno reference.
It sounds apocalyptic
That's all of the lost souls who jumped to their end letting their voices be heard.
Big facts
They absolutely did not anticipate this.
The wind speed will drive the frequency that the air coming through the slats vibrates at. If that frequency matches the "resonant" frequency (think of the washing machine jumping around at a certain speed) of the barriers, then they will vibrate much more aggressively and loudly. This presents another problem though.
The model they used to test this did not include the uprights or support cables. There is a phenomenon called Acoustically Induced Vibration (AIV) which can lead to fatigue failures, cables wearing through metal and bolts coming loose, caused by high volume sound making structures vibrate, especially if at that resonant frequency. I really hope they carried out separate studies to ensure that AIV will not affect the bridge supports, as they only seem to have tested what happens to the main road deck of the bridge from the overall force of the wind. They may be able to dampen the noise and vibration by adding dampers to each railing, if the railings are vibrating at their resonant frequency.
That's the sound of liberal souls crying.
A Brian Eno reference on a KPIX5 news report? Never expected that. Wilson Walker's a legend!
trufe
I would be Careful, if it reaches a frequence, that hits its own frequence, the bridge will break down!
Apparently, most people don't understand that. Including the genius bragging about this 'special feature'. Your comment is the 1st I saw that mentions it. I thought resonance & frequency was part of an architect's training?... 🤔
It's just the new railings that are causing the noise. The bridge deck itself is not vibrating.
Comments from other vids from bridge builders say...that’s not good.
I fell for that spider on your profile picture -_-
Really?
They have a sinking/leaning sky scraper. The bay bridge literally crumbles. And now they are trying to write this creepy sound off as a feature? They cant do anything right......
Who is "they," exactly? The fact that you're lumping all those structures together and blaming a single entity indicates you don't have a clue what you're banging on about. Or is the "they" just humanity in general? 'Cause it would be reassuring to know you aren't one of us.
san francisco so creepy i swear. everything about it. stg wouldnt be surprised if that thing collapses
Soon we’ll all hear the Trumpets blow from the Heavens
Let’s face it, this is an engineering screw up. It was never mentioned in any announcements or descriptions of work to be done. The guy saying the sound was anticipated is just plain lying. An insult to everyone’s intelligence. For those of us who live near the bridge this is more than a distraction. This is a harmful noise that will drive some people crazy. The bridge people need to stop trying to sell this as a “feature” and get to work on a fix that will make it go away. If they choose not to correct the problem, I’m sure a strong legal approach will point out the liability of the unwanted noise and and effect it has on all who have to live with it.
I miss 5 minutes ago when i hadn’t seen this
Search: Tacoma Bridge
If that bridge is going into a harmonic wave, it will collapse.
This is what happens when you go with the lowest bidder.
That vibration could be detrimental to the bridge structure. And who wants to hear a leaf blower all day long?
Property values 📉?
Like that guy said it's a feature 🙂
That sound makes me feel weird. Its a little demonic. Not good vibes
When drivers drive in the shoulder grooves on the freeways, they growl. Gee what a fascinating phenomenon!
The feature probably most can do without.
I did a construction job in Venice beach, the neighbor had a giant vertical tube in back of the house, facing the ocean, that made a similar sound. Day and night.
Thats cool
Everything is art, even design flaws.
In the Book of Revelation, seven trumpets are sounded, one at a time, to cue apocalyptic events seen by John of Patmos (Revelation 1:9) in his vision (Revelation 1:1). The seven trumpets are sounded by seven angels and the events that follow are described in detail from Revelation Chapters 8 to 11.
We used to live 5 minutes walk from this when my husband was active duty military and this would have driven me insane. As he had been a helicopter pilot, he might not have heard it, and handed us some earplugs!
that's so cool what helicopters did he pilot?
this is kinda bad. if this is a resonant frequency it will eventually vibrate the bridge into pieces.
It's just the new railings that are causing the noise. The bridge deck itself is not vibrating.
That would annoy me, I would definitely sue if they didn’t find a different solution to make it silent.
"It sounds like wailing"
I used to live aboard and the rigging always sings in a high wind. Go down to a marina during a storm for the full concert.
