browser-based noise meters that show students how loudly they speak. That post was written in response a request for an alternative to the iPad app Too Noisy. Today, the developers of Too Noisy released a browser-based version of their app.
Too Noisy for your browser displays a large meter whose needle moves in response to the sound in your classroom. To use the Too Noisy meter just open the site and give it access to your computer's microphone. Too Noisy currently works in Chrome and Opera.
Applications for Education
Projecting the Too Noisy meter for all of your students to see could be a good way to help them understand the appropriate volume for conversations while working on group activities in your classroom.
