BHTX - I did a similar test with my younger sister a few years ago, when I first bought my ratshack meter. I set it to A-weight, fast, and asked her to scream into it.
Her first try was 110db so I set the sensitivity notch to 120db and asked her to scream again. It barely lifted, which is around 112db. I should have stopped there, but she wanted to try again.
On her third scream, I swear she fell into some type of zone where she went from screaming to generating an inhuman sound that pegged the meter at 126db. It's hard to explain, but her scream changed from an "aaaah" to something closer to a whistle. She was about .25m from the meter, and I was another .5m away. It hurt like hell, causing my ears to ring badly for 3 days.
