The whistle produces a soundwave that is high in pitch but only audible to dogs as they have a greater range of hearing than humans.
So to humans it is low in loudness
Yes, that is correct. The soundwave produced by the whistle may be high in pitch but low in loudness for humans, making it inaudible to them but audible to dogs with a greater range of hearing.
