Wouldn't the response range of the instrument/mixer/amp limit the contents of the signal that is being fed into the drivers?
At first i though the same thing that the mixer has limit at 20000 hz so no problem who cares if the in ears are going to 43000 but ky teacher told me that the 43000 freq response is effects the harmonics under it with such a way that still is a problem..
Try google about supersonic sounds damage ear or something like that you will find a lot of details..
Also try asking your ear doctor or audiologist about it
Also a tip for everyone who uses in ears.. dont ever play with just 1 in ear in your ear.. i see many playing with just 1 and having the other ear open to get sound from outside stage etc.. this is still a huge problem during time they can even start walking wrong..
The same damage can be done when you speak at phone with 1 ear all the time or using a bluetooth at the 1 ear all the time
