Loud noise at certain frequencies can destroy the ability to hear at those frequencies but still allow you to hear tones above and below that frequency. You end up with gaps in your aural perception that you don't notice because your mind fills in the empty spaces unconsciously, but in a case where a pure tone is played on its own the absence becomes identifiable.
So I wouldn't worry about it, especially as nothing can be done - what's gone is gone. Unless a dog whistle is going to save your life one day, not hearing ultra-high frequencies is of no real importance.
