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.
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 pupils at the back of class not hearing as well as those at the front. Pupils may lose concentration.
Classroom with soundfield system installed
- Teacher speaks at normal voice level, avoiding voice strain.
- Soundfield amplification means that all pupils hear at the same level wherever seated in the classroom, maintaining interest and attention of the pupils and providing a better learning environment.
