A soundfield system is an amplification system that provides an even spread of sound around a room.
This is beneficial for deaf students, as they can hear the teacher’s voice clearly from wherever they are seated, even if the teacher is facing away from them. All students benefit from the soundfield system's amplification, and the teacher doesn’t need to speak loudly to reach everyone.
We no longer loan out soundfield systems but many manufacturers or distributors provide a free trial. The products listed below give you an idea of what is out there.
