‘Ghost howl’ sounds mysterious in San Francisco

A strange sound can be heard on the bridge, which is a famous landmark of the metropolis.

In San Francisco, residents of the United States were frightened by the mysterious sound of a “ghostly howl.” He was heard on the Golden Gate Bridge. IFL Science writes about it.

It has been noticed that car drivers increasingly hear scary noises that the structure “sings” especially on windy days. They say it’s like “ghost breathing”.

Meanwhile, the “ghost howl” is believed to have originated in 2020 after the reconstruction of the bridge. The structure is protected in case of strong winds. In particular, railings with thinner slats were added to the bridge than before.

But this has some unintended effects. A light wind of 35.4 km/ho more blowing from the north produces a low tone, while a wind of 43.5 km/ho more produces a “howling” at higher frequencies.

Together it sounds like a creepy “serenade”.

Recall that earlier in the city of Blairgory in Australia, a local resident in his house was confused by a poisonous snake using a phone charger.
