-What is it?
It is a headphone with an auto-volume controller and a led showing outside noise level.
This project has two parts, the p5 part and the LED part. The p5 part mainly controls the volume of music playing in the headphones. For example, in super noisy environment, the volume of music playing in the headphones would automatically become higher to allow the user listen more clearly, while in quiet environment, the volume in headphones would become lower in order to avoid disturbing others.
Everyone frequently uses headphones
