Personal Radio Aids with Soundfield Systems for deaf children

Soundfield Systems 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 so the use of a personal radio aid system is also necessary.

Radio aid systems can be connected to Soundfield Systems, to enable the pupil to benefit from both systems. 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.
