How many millions will it take to correct the problem?

They are not planning to fix it. For now, they are delighted with their "singing bridge."

We'll see how long that attitude lasts. When they finishing adding the new slats, the bridge will be even louder than it is now.

I just checked, and "earsore" is a word. The magnificent Golden Gate Bridge, that I drove across daily, has become an earsore.

Good. San Francisco should be able to produce an impressive pack of jumping enviros, and for the first time in their lives they might be on to something. The sound is similar to whalesong.

The enviros can join the class action lawsuit by local residents who don't appreciate being kept awake by a howling bridge.

I watched it all. An over four minute video and they couldn't devote 10 straight seconds of the sound without their yaps going. The sound.. the entire topic. Then at the end the blond informs there are different variations. Is that like a variety of differences, I wonder?

Yes. In its time it was nicknamed, Galloping Gertie. It was since rebuilt and another bridge now runs parallel to it with each bridge having one way traffic-one going to Tacoma and the other going to Gig Harbor and the Peninsula.

Pretty sure that new sound - heard for miles and miles - will cause even more suicides. I’m serious.

The noise of it is too loud. I am sure pedestrians want to walk the bridge for the view and the experience. Now they have to wear earplugs.

There was a dog in that car.

He died.

OMG, can you imagine what that’s doing to dogs?

I had to shut it off.

Made me want to scream.

It’s painful.

>Listen to the links.

While this happened before the new addition to the bridge, you can listen to the whole bridge if you have an iPad.

Go the to App Store and download an app called “Play The Golden Gate Bridge”.

The Bridge was first sampled in 1975 and eventually turned into an app that can be played like a harp or soundboard and can also be MIDI controlled.

It’s kind of a one trick pony but it does make some interesting noises.

I can remember a condominium building on the S. Alabama beach in Orange Beach. When the wind was of sufficient speed and the correct direction the balcony railings would vibrate and make a sound loud enough to drown conversations or wake people from sleep. It was a primarily vacation rental building and guests were not happy paying for a weeks stay and a noise “concert” All the railings were replaced to prevent the noise.

They have inadvertently created the “World’s Largest Harmonica!’

Yep - marching troops also employ route-step to keep from setting up such frequencies when marching over smaller bridges the way keeping in step has been known to do.

In April 1831, a brigade of soldiers marched in step across England's Broughton Suspension Bridge. According to accounts of the time, the bridge broke apart beneath the soldiers, throwing dozens of men into the water.

After this happened, the British Army reportedly sent new orders: Soldiers crossing a long bridge must "break stride," or not march in unison, to stop such a situation from occurring again.

Structures like bridges and buildings, although they appear to be solid and immovable, have a natural frequency of vibration within them. A force that's applied to an object at the same frequency as the object's natural frequency will amplify the vibration of the object in an occurrence called mechanical resonance.
