voice and program material are distributed at a consistent level to
each student. A sound field is created by a classroom sound system
specifically designed to slightly amplify the teacher’s voice using
speakers strategically placed throughout the room. The key to success

is not simply amplification, but increased intelligibility. To achieve this
goal, effective sound field systems must accomplish the following:
■ Amplify the teacher’s voice slightly above classroom

Instant Alert email

■ Distribute sound evenly throughout the entire classroom by
using multiple speakers
■ Provide superior audio performance in frequencies associated
