Assistive Listening Devices with Soundfield Systems for deaf children and young peopleSoundfield Systems are an amplification system that evenly distributes the teacher’s voice around the room, using a microphone and speakers thus enabling pupils to hear equally well regardless of where they are seated or which direction the teacher is facing. They provide a consistent level of sound from the primary source, usually the teacher, around the classroom, at about 10dB above the background noise. However, they cannot provide the higher signal to noise ratio that is essential for deaf children and young people. Remote microphone technology can be used in conjunction with a Soundfield System. The teacher uses the soundfield microphone and the transmitter is connected into the soundfield. The sound is rebroadcast from the soundfield through the transmitter to the hearing device used by the deaf children and young people. However, QS12 in Quality Standards for the Use of Personal Radio Aids states that where soundfield systems are used in conjunction with personal radio aids, equipment must be selected and set up to ensure that the performance of the personal radio aid system is not compromised.
