What Happens When
Students Can’t Hear?
• National Geographic Reports
– A Cornell University Study
Cornell University Conclusion
• If students can not focus on the
spoken work of the teacher,
students not only loose the desire to
learn but also the ability
– Poor acoustics can interfere with the
student’s development of spoken
language, reading and writing skills, and
academic performance
Evans, “Community Noise Exposure and Stress in Children”

Enhancement vs. Amplification
• Traditional amplification system
– Amplifies and makes the voice or
presentation louder but not necessarily
clear and understandable
• Enhancement system
– Distributes the voice evenly throughout
the listening environment
– Voice is clear and understandable
regardless of physical position of
speaker and listener

Student’s Hearing
• Adults have a distinct advantage in
audio processing…
– Children’s auditory network not
developed until 15
– Adults have life experience that fills in
the blanks
– Children DO NOT have the years of
experience
– Children have difficulty performing
auditory-cognitive closure

Student’s Hearing
Human
speech
is
filled
with
gaps.
• There are gaps in sound and meaning when
we speak. In adults who have the benefit
of experience, the brain automatically fills
in the gaps and makes language meaningful.

Improved Phonemic Awareness
• Phonemic Awareness (sounds of
spoken language) is a prerequisite to
successful reading & comprehension
• Teachers instruction in sound

What Teachers Say
• You can take away my desks and manuals but I’ll
bar the door if you take my amplification
equipment. Louise Ortberg, Fulton school
• I love my sound field! It has made a huge
difference in the fatigue level of my voice. It is
less strained and I have fewer sore throats as a
result. Sue Emmendorfer
• I found the microphone to be very beneficial
when reading journals, textbooks, or reading
stories. The kids volunteer to read out loud a lot
more when the microphone is in use. Scott Wilkie

What Principals Say
• Made a significant change in the learning
environment
• Students more actively engaged in learning
process
• Teachers spend more time teaching less
time managing student behaviors
• “I believe that the increased scores can be
directly attributed to the implementation
of sound enhancement because we made no
other significant changes in our
instructional program or staff”
