So, I brought it up to 52-52K RPM and looked at my observer, but he was not there? he was running around the corner of the hangar, holding his hands over his ears :). In flight the noise was activating the microphone on the headset too.

Pretty funny mental image, but being hard of hearing is no defense.

Here's a little unsolicited tidbit, picked up when my hearing began to 
deteriorate due to too much rock&roll in an earlier life/career: As your 
hearing gets worse, only your threshold of sensitivity moves up; your 
threshold of pain stays at the same level. Ever notice that grandpa 
keeps saying 'Huh?' over & over as you repeat your statement louder & 
louder, until he suddenly says 'Well, you don't have to shout!' ?
