Exploring the relationship between classroom noise levels and student learning

Noise levels in elementary classrooms can influence both student learning and teacher experience — excessive noise is linked to reduced focus, more off-task behavior, and lower academic performance, particularly in early elementary grades when attention and language development are most critical. This paper examines that relationship in Kindergarten through Second Grade classrooms, and evaluates an engineered device built to encourage quieter learning environments.

A literature review found that higher classroom noise levels correlate with more behavioral disruption and lower achievement, pointing to a need for simple interventions that help teachers maintain focus without added burden. To address that, the study team designed and tested a device that monitors classroom sound levels and gives students real-time feedback, with teachers able to pair it with positive-reinforcement incentives such as extra recess for maintaining a quiet room.

The device was piloted in early-elementary classrooms over one week. Teachers completed surveys rating how much quieter the classroom became, whether the learning environment improved, and how user-friendly the device was, alongside open-ended feedback for future improvements.

• What is the relationship between noise level and student learning and experience?
• Does the engineered device effectively reduce classroom noise?
• Does the device improve the learning environment?

Preliminary findings suggest that simple, student-centered engineering interventions can meaningfully help teachers maintain quieter, more productive classrooms — demonstrating the potential for engineering solutions to support classroom management and, ultimately, young learners.
