Questions people ask
What is the loudest alarm sound?
At the same volume setting, sounds that start suddenly and sit in the high-middle range feel loudest. Among ours, the air raid siren, the air horn and the shrill alarm clock get 5 out of 5 on our wake power scale.
Can an air horn alarm damage my hearing?
Your phone speaker cannot get anywhere near a real air horn. Still, do not play any alarm at full volume in earbuds or right next to your ear.
