If the kid has screaming problems, he shouldn't be in that class in the first place. They should simply place him in some kind of special education program.
I've heard of situations where kids don't do well in school. The deaf program director modifies deaf students' grades when they don't do well in school. For instance, if a deaf student got a 60 in class (This school district only has A, B, C, & F. No D.)... that deaf director will give that student a 70 and add a comment of "grade modified". Well, this student has a learning disability. All the other deaf students in those classes do fine, except for this one. However, this student is given the so-called "equal & fair" opportunity to pass the class and move on. This student later graduates and is now working for his dad for free. It took him 5 years after he graduated before he actually got a job working for his dad. His only earning is to be spoiled by his parents.
There were other students who were not as bright as he was. They put those students in special education classes. Those students math and reading levels were lower than average. They still struggled to get through. Yes, it took them an extra year... but it was worth it. They managed to graduated with grades that they actually earned. Now, they have successful jobs.
If the school had actually put the first guy in a special education class, he would have done better and graduated with what he actually earned. Then, he would have learned how to actually get a job. Being "equal & fair" to students, regardless of their mental or physical limits, isn't always appropriate. They should be evaluated and placed in the right place. If the world wanted to be fair with everyone, we'd have a Harrison Bergeron on our hands!
