Soundfield Systems/Classroom Amplification
Soundfield systems are designed to overcome the problems of background noise and distance from the teacher. It provides surround sound throughout the classroom, amplifing a teacher's voice about 4-8 decibels to create an improved voice signal. The teacher's voice will be clearly audible and intelligible above background noise. Learners hear equally well n o matter where they are in the classroom.
Soundfield systems benefit all students, especially those with a mild/moderate hearing loss, specific auditory and other special needs. This allows teachers and learners to move freely about the room.
A soundfield functions best in learning spaces with favourable acoustic qualities.

Several types of Soundfield systems are available for trial.
4 speaker systems provide high quality sound and good coverage throughout the learning space. They require installation involving wiring each speaker to the amplifier and attaching speakers and amplifier securely to a wall surface.
The 4 speaker systems are the preferred option for a permanent installation.
Frequency Modulated (FM) 4 Speaker System
Uses FM radio signals for transmission and has multiple channels.
Infrared 4 Speaker Soundfield Systems
Uses infrared signals which are contained within the walls of a room, and avoids interference from radio signals. The system has 2 channels.
Movable Infrared Soundfield System Infrared (Usually wall mounted)
Uses infrared flat screen sensor and speaker combination with 2 channels and a shared teacher microphone.
Moveable FM Soundfield System (can be mounted)
Has a single column speaker and uses multiple channel FM radio signals. 2 channels can be selected for the teacher and hand around student microphones.
