Air Horns

What type of air horn should I get my husband for his truck?

I keep finding air horns that are 135 dB, but I don't know how loud that is. Is that like a fire truck? He wants something crazy loud, what would be good and where could I get it?

1. 135 db is pretty loud....to put it in perspective a jet taking off from a runway is around 137 db. check out hornblasters.com for some good ones.
2. I'm not much help in where to get it from but I've seen/heard a few trucks up here with train air horns. That's right, those loud locomotive air horns. Dunno if it's legal but who cares...it's scare any slow 4-wheeler out of his way. :)
