I substitute teach most days, and was in for a band teacher this first day back from break.
I have real sound problems. Easily overwhelmed in loud situations, many problems separating out the sound I want from background/competing sounds, and problems with unexpected noises. I have had problems in the classroom in the past due to background talking.
One class was the brass and woodwinds, and the next was percussion. I was sure I would feel awful by the end of the day, but actually enjoyed the experience. Feeling the force of the sound, the vibrations from the drum line, and the long tingling of brass was actually quite nice. But, I was listening to a main sound, not trying to separate out one from many. Though loud, the experience was not harmful.
