Sheriff's Office: 'Unfortunately, It Is the Sounds of Nature'

Emerging cicadas are so loud in one South Carolina county that residents are calling the sheriff's office asking why they can hear sirens or a loud roar. The Newberry County Sheriff's Office posted a message on Facebook Tuesday letting people know that the whining sound is just the male cicadas singing to attract mates after more than a decade of being dormant, reports the AP. Some people have even flagged down deputies to ask what the noise is all about, Newberry County Sheriff Lee Foster said.

The noisiest cicadas were moving around the county of about 38,000 people, about 40 miles northwest of Columbia, prompting calls from different locations as Tuesday wore on, Foster said. Trillions of red-eyed periodical cicadas are emerging from underground in the eastern US this month. The broods emerging are on 13- or 17-year cycles. Their collective songs can be as loud as jet engines, and scientists who study them often wear earmuffs to protect their hearing.

After Tuesday, Foster understands why. "Although to some, the noise is annoying, they pose no danger to humans or pets," Foster wrote in his statement to county residents. "Unfortunately, it is the sounds of nature." (More cicadas stories.)
