Teachers
Benefit
Hearing is believing
With sound enhancement in
the classroom, everyone can
participate and hear what
the teacher is saying.
Microphones provide access
to the teacher from anywhere
in the classroom, without shouting
or disrupting instruction.
The benefits are clear
When teachers use a microphone
system during instruction, they have
less voice fatigue, more energy, and
students feel more included. Teachers can
speak in a normal tone and everyone in the
classroom hears what is stated.
Instruction
within reach
With the pendant microphone,
teachers can be heard and
control audio from anywhere
in the classroom.
Both hands remain free
for writing and sharing
lesson details.
Research has shown that the addition of a sound
enhancement system in the classroom provides better
classroom management and fewer discipline issues
"I don't have to repeat instructions."
