I've never wore a bear bell but have seen many who do. Guess it's better then nothing but would drive me crazy after a few hours, bing, bing, bing.......
I just hum, sing, talk to myself anything to make some noise.
The times I ran across bears I just make sure they see me and yell-make loud noises and they run a way, maybe I've been lucky.
Bear spray is not a bad idea, make sure you know how to use it, useless in strong wind, a whistle and air horn are other options, anything that makes noise.
Wouldn't worry much about it, bears don't like people. Let us know about your trip!
