Golden Gate Bridge emits strange sounds as far as 5km

The famous 83-year-old bridge emits a low, deep echo that spreads as far as 5km after being replaced with a new railing.

San Francisco authorities are trying to prevent the low-pitched sound emanating from the Golden Gate Bridge, which annoys some residents. The sound was first recorded on June 5. Residents said they could hear it from nearly 5km away.

The strange sound was the result of a project to improve the Golden Gate Bridge.

Over the past 5 years, Shirin Kermani and her family have often been to the Golden Gate Bridge in many different weather conditions. However, she had never heard strange sounds until recently.

"Even when walking towards the bridge from Lincoln Boulevard and Battery East, we still hear something very sad, like the sound of a didgeridoo instrument or a song for meditation," Kermani said. Although many people find this sound annoying, Kermani thinks it brings a sense of peace.

The strange sound was the result of a project to improve the Golden Gate Bridge. The project aims to upgrade the bridge in terms of aerodynamics under high wind conditions, ensuring safety and structural integrity for many years to come. The project involves replacing the railing of the west pavement with new, slender piles that allow more air to flow through.

Initially, the engineers didn't think the bridge would make a sound, according to Ewa Bauer-Furbush, chief engineer at the Golden Gate Bridge and Road Transport Authority. They are consulting experts to solve this problem.
