5. What is soundfield?
A Soundfield is an amplification system which provides an even spread of sound around the room.
A typical 'soundfield' consists of a microphone worn by the teacher, a wall mounted amplifier and wall mounted speakers around the classroom.

6. CLASSROOM WITHOUT SOUNDFIELD SYSTEM INSTALLED
Teacher raises their voice level attempting to be heard at back of class, risking voice strain.
Clarity deteriorates over distance resulting in students at the back of class not hearing as well as those at the front. Students may loose concentration.

7. CLASSROOM WITH SOUNDFIELD SYSTEM INSTALLED
Teacher speaks at normal voice level, avoiding voice strain.
Soundfield amplification means that all students hear at the same level wherever seated in the classroom, maintaining interest and attention of the students and providing a better learning environment.
