Well, if ultrasound was able to produce significant energy input to the cochlear hairs...one would be able to hear ultrasound (which one cannot).
That being said, exposure to >120 dB ultrasound can damage your hearing (I believe this is because response functions of the ear start becoming nonlinear).
Seems self contradictory on your part, unless you're saying people who otherwise can't, can still hear ultrasound, so long as it's over 120db. So, my top frequency for hearing is down to 14.5k from before, last time I tested it. Are you saying that 15.5k sounds now won't damage my stereocilia? That doesn't make sense, unless those things actually get stronger with age. Usually, things in the body get weaker with age.
