The loud noises you may hear blasting from your electronic devices this afternoon are no cause for concern.

At 2:20 p.m. ET on Wednesday, the federal government will test two emergency alert systems on televisions, radios and certain cellphones across the country.

The emergency alert system (EAS) test will be sent to TVs and radios. The wireless emergency alert (WEA) test will go to cellular consumers who have opted in to receive test messages, which will display in either English or Spanish depending on their phone's settings.

"The test is intended to ensure public safety officials have the methods and systems that will deliver urgent alerts and warnings to the public in times of an emergency or disaster," according to a press release from the Federal Emergency Management Agency, which is working in coordination with the Federal Communications Commission.
