The best ways to provide assistance for your student who becomes quickly overwhelmed by everyday noises are; you creating a personalized support plan, schedule sensory breaks, and teach your peers empathy and understanding. A welcoming, inclusive classroom setting combined with environmental adjustments and constructive criticism can make students feel more at ease and help them succeed in their everyday learning. 

Establish and consistently enforce classroom rules regarding noise levels and behavior. Ensure that students understand the impact of their actions on their classmate. I have also seen headphones work very well for students that struggle with noise. Hope this helps.

To support your student, it's important to create a classroom environment that promotes understanding and empathy. Start by educating the class about sensory sensitivities, helping them recognize how certain noises might affect their peer. You could implement a "quiet time" or create designated areas for students who need a break from sensory overload. Provide your ESE student with noise-canceling headphones or fidget tools to help manage discomfort. Establish clear, consistent expectations for behavior, emphasizing respect for others' needs. You might also introduce a signal that your student can use when they feel overwhelmed, so they can discreetly communicate their discomfort. Praise positive behaviors and efforts from the class to create a more supportive, inclusive atmosphere. Fostering empathy will encourage students to be more considerate and reduce intentional disruptions.

Discuss with your class as a whole that they should try to put themselves in others shoes. If any of them were having a very hard time in class, they would want empathy and help, not to have your peers make fun of you making it harder to adjust.
