How Much More Could You Get Done With 50% Fewer Behavior Issues?

About 2 weeks ago, a co-presenter (Alex) from an audio/visual (“A/V”) vendor at a start of year professional development offered me a wearable mic for my 3-hour stint – which I declined out of teacher-voice pride (maybe hubris?). When it was offered to me again about an hour into the training I was glad I accepted because my vocal cords came to appreciate the benefits of sound reinforcement. Regardless of where I stood or which direction I pointed, I could speak at a conversational volume and every single person in the room could hear me as if I was standing next to them. This experience got me super interested in the research and work behind Audio Enhancement, who have somehow slipped under my radar until this point.

At its simplest level, their sound solution is a wearable mic that projects a teacher’s voice at the ideal learning volume for every student, in every part of the room. I followed up with Alex to get some research on what effect this has on student learning and teacher retention. I was blown away by some data points from independent research institutions (non-Audio Enhancement sources):

  • Sustained year over year achievement gains in core academic subjects >10%
  • Fewer discipline issues and greater on-task behavior (up to 17% increase)
  • Reduction in vocal fatigue symptoms and as a result teacher absenteeism (as high as 36% improvement)
