The emergency alert siren on the Midland ER310 is pretty loud—loud enough to grab your attention when it matters. The manufacturer designed it specifically for emergencies, so you won't miss any important alerts, even if you aren't glued to the radio.
They don't give exact decibel levels, but from what we've found, people generally think it’s plenty loud for what it needs to do.
Aside from the siren, the ER310 also comes with some nifty features like multiple power sources: a hand crank, solar panel, and a rechargeable battery. All this makes it pretty reliable during power outages or on outdoor trips.
