The quest to solve the mysterious ‘eerie’ hum of the Golden Gate Bridge

[Still Waters]

Somewhere in a wind tunnel on the south-western side of Ontario, a group of the world’s leading bridge aerodynamics and acoustics experts are puzzling over a full-scale model of the railing of the Golden Gate Bridge.

The experts have been contracted to solve the mysterious problem of a strange humming sound that has been emanating from San Francisco’s famous bridge for the past year, driving some nearby residents to a state of madness.

The sound, heard only on windy days, has been compared to a “ghostly harmonica”, “chanting monks” and a “wheezing kazoo”.

I would not have thought that it is such loud. Horror!

That's actually what I thought, and has probably occurred to the engineers as well -- some sort of change in the bridge's structure.  And indeed it might be a crack, causing an aeolian harp effect.

So they retrofitted the bridge to be the worlds largest Harmonica?

Really? Thought cables, as a small cable and especially clothes lines will emit eerily loud, howling noise(S) on a rather windy night.
