A bell is probably less startling, and sounds less threatening to some; a loud horn may cause them to crash.
That's the difference between city/suburb riding and rural riding. No one hears you yell (or scream) in the country. I still have my voice to use when appropriate, but when entering a blind one lane underpass, for example, there is no substitute for loud noise. (Except when a train is going over, in which case it's down to the headlight strobe at night, or dumb luck in daylight.)
Okay, you've piqued my interest - why does "no one hears you yell (or scream) in the country", barring the specific extreme instance you describe? I need to do it far less often when riding in rural areas, but I've still been able to get people's attention.
