In addition to personal or small group sound fields in the
classroom, teachers and administrators are also turning to the
use of classroom-wide sound fields. Numerous studies verify the
educational benefits of sound field amplification systems, including
increased on-task behavior and student attention to oral instruction,
improved comprehension among ELL students, and reduced
vocal strain and fatigue for teachers.
As administrators strive to meet Common Core assessments goals, they
must also address groups with diverse needs such as ELL, ESL and students
with special needs. Teachers need to convey audio information to students
in all of these groups in a clear, concise manner.
The Classroom Infrared Audio System can help teachers teach and how students learn. The system
includes two array speakers for superior sound distribution (or an optional four speakers for larger rooms).
Array speakers (commonly seen at concerts) focus a narrow band of sound directly at the students instead
of bouncing it off the walls in a random and confusing fashion. This enhanced sound projection improves the
critical signal-to-noise ratio, therefore improving the clarity and intelligibility of the amplified audio. “There is also a port
to connect a secondary audio support system for students with special needs. Read more about this by visiting
