Ultrasonic Range Finders Question


Does anyone know if the frequency used by these rangers, is in the range heard by dogs?

I'm thinking of getting a couple for a project, but don't want to use them if my dogs are going to become rabid.

Doh! Thanks for that, ignoblegnome. That'll teach me to search first.  :(
