classroom noise by projecting and straining their voices. A study showed 80% of
teachers reported vocal fatigue and average two days of sick leave per year for
voice-related problems.
Three factors influence the ability to hear and understand what a teacher says in
the classroom:
• Distance from the teacher
• Reverberation
• Background noise
One way to combat background noise is with the use of a sound field
amplification system. The benefits of an amplification system include:
• Students pay attention more readily
• Learning disabilities decrease
• Dramatic increase in listening, language, and vocabulary scores
• Performance on word analysis
• Improved math concepts and computation scores
• Teachers relieved voice strain and reduced absenteeism
