Sound System

Benefits of a Sound System in the Classroom

Get an introduction to the Sound System in the classroom including learning how to use the equipment and understand the benefits of using a sound amplification system with students.


"I speak loudly and don't need a microphone."

  • Sound systems evenly distribute your voice and audio throughout the classroom. The volume of your voice is not the only thing teachers should consider.
  • Reduces ambient noise that serve as a distraction for many students.
  • Reduces tension and anxiety by eliminating the need to raise your voice to get student's attention.

What if not everyone is hearing you like you think?
