How Classroom Audio Helps Learning
Can your students hear what’s said in class?
As sound travels, the intensity of the sound wave decreases
by 6dB for every 3 feet it moves away from the speaker—this is known as the inverse square law. Without a classroom audio system, a teacher’s voice will taper
below the maximum allowed classroom background noise volume of 35 dB, making it
difficult for students to hear instruction, depending on where they sit in the
What about a “teacher voice”? The problem is that using a
louder voice can be perceived as yelling by some students, especially those
right by the teacher. Speaking louder can also affect intelligibility and is a
greater strain on a teacher’s energy, stamina, and voice. It can become a
problem for both teachers and students.
Luckily, the solution to overcoming the inverse square law
and making learning more equitable is simple and has been around for years: Classroom
Audio Systems! Putting Audio Enhancement’s XD microphone on the teacher defeats

who was searching for a way to provide an equitable education for her two deaf
sons. She designed a sound system for their classrooms and quickly discovered
that all students could benefit from audio enhancement.
