How to Measure Noise Levels With Your Phone: A Practical Guide
Noise is part of everyday life. It can come from traffic, construction, household appliances, music, conversations, classrooms, workplaces, or nearby businesses. While some sounds are easy to judge by ear, it can be difficult to estimate how loud they actually are.
