TULSA, Okla. - You're in the car and you've got the radio cranked up insanely loud. Chances are, you're not going to hear that ambulance siren wailing behind you.
Soon, even if you can't hear it, you'll be able to feel when an emergency vehicle is coming.
Oklahoma's largest ambulance company will become the first ambulance service in the nation to outfit its entire fleet with new Howler sirens, designed to emit low-frequency tones that penetrate objects within 200 feet — such as cars — to alert drivers.
