A weird fluency experience at a concert

A weird fluency experience at a concert I went to a concert with some friends, and one insisted I wear earplugs since it was a loud concert. Something about the earplugs dampening high/mid frequencies made it *much* easier to speak fluently. It was a freeing moment, to say the least. This is coming from someone (male, 22) who has had speech problems his whole life, working past everything but the occasional (sometimes severe depending on the situation, like saying my name) stutter/speech block the last ~10 years. Anyways, wanted to share this with you all. R-r-r-rock on!
