If you've been wondering what the Golden Gate Bridge noise is, you're in for a surprise. The hauntingly eerie sounds can be heard all over the Bay. And it's all thanks to a new railing installation project.

The Guardian reported that Paolo, a Golden Gate Bridge, Highway and Transportation District spokesperson said, "The new musical tones coming from the bridge are a known and inevitable phenomenon that stem from our wind retrofit project during very high winds."

To strengthen the bridge's resistance to extremely high winds, new handrails were installed that allow air currents to move more steadily over the structure.

You can hear the harmonious tunes coming from it when it's a rather windy day. 

The new renovations are "to ensure the safety and structural integrity of the Bridge for generations to come," said Paolo.

According to the Golden Gate Bridge's website, more than 10 million people visit each year and around 40 million cars travel across the platform.

If you're looking to experience the marvelous sights and sounds, there are many ways you can in the form of walking tours, bike rides, and nearby hiking trails. 

Depending on when you visit, you might be lucky enough to hear the bridge's song carry on the wind.

There have been mixed reactions to the noise on social media with one person referring to it as "an ultra-sonic weapon," and another saying "maybe that was just Jim Carolla belting out a few tunes."

This massive "musical instrument" features massive sweeping towers and cables, and spans a whopping 8,981 feet. That's almost two-miles long!

If you happen to be visiting San Francisco, this is one stop you might want to add to your list of must-sees.  

It looks like this platform serenade has no intention of being fixed. The SF Gate reported that officials say they have no plan on repairing the humming noise caused by high winds.
