Sound which you can't hear isn't going to be dangerous to the ears in a conventional sense. Of course at electrically significant power levels, it is just potentially dangerous generally.
Ultrasound can also cause tissue damage at high intensity.
I'd be cautious about making claims that humans are not damaged by high intensity sound, even if inaudible.
Perhaps this is what you mean by saying "a conventional sense" but I just thought I'd expand on your answer in case others read it and get the wrong idea.
