Help!!!!! Siren went off

Heather • 💙Otto Wayne 9/7/18 💙💚Owen David 5/22/20💚

We recently got the arlo pro 2 security system and the siren which the box says puts out 100+ DB went off when my 3month old was only 4ft away! I was able to turn it off almost immediately but now I’m worried about him. What are the chances it damaged his ears/hearing?! How would I know? Please help!
