Teachers always feel students are too noisy when they are talking, so my partner, Haoxi, and I disgined a program to solve this kind of problem. We found a way which we thought is very useful:  use bigger and much more uncomfortable noise to treat with the noise that students made. We need to use a beezer, a loudness sensor and a Microbit. The noise the Microbit made won’t stop until the stop of the student’s noise. Futhermore, we used a button to control the microbit so it won’t make noise when the teacher is teaching.
