NDCS have updated their guidance to explain what radio aids are and how they can help deaf children. It describes the different types of radio aid systems and how to use and look after them. It also looks at classroom soundfield systems and acoustics.
NDCS also recently worked with the FM Working Group to update the Quality Standards for the Use of Personal Radio Aids, available from http://www.ndcs.org.uk/professional_support/our_resources/education_resources.html#contentblock25. This resource is online only.
