Yes, she has hearing loss, but they don't generally even test for hearing loss before school age, so it's kind of a 'neither here nor there' type of thing for her ped. Some of the other kids had their hearing tested as well when I started raising a ruckus, and they all had pretty much the same results, so the local reaction is, 'eh, whatever'. The most soul crushing part of it is when we went birdwatching with the kindergarten and we were all quiet to hear the birds and they all complained that they didn't hear them at all until a seagull screetched and then they were all like "now I hear it!"...:(
The dance music they use for exercise is painfully loud to me, twice a day for half an hour. They use two PA type speakers, so it's not exactly a rock concert setup, but the room is quite small. I am admittedly sensitive to rock concert levels, so it might not be 'painful' to most of you guys, but I think definitely inappropriate daily levels for kindergarten.
He is probably not aware how loud he might be, I am sure he feels the butt cheek vibrations every time but unable to hear must be hard to control. Get him one of these and show him what is the acceptable range (depending on his location) so he can start measuring his farts.

Can I still use that voltage value and the knowledge that my headphones say: Sensitivity headphones 101 dB SPL/V
do maths and get dB?
Or can you literally put something like this in-between the earpieces to get it: http://www.amazon.com/gp/product/B000EWY67W/
