There is a range of ALDs available, and a personal radio aid or propriety microphone device might be recommended in educational and/or home settings.
They have the potential to greatly enhance deaf CYP’s listening experiences by making speech more audible in situations where distance, background noise and reverberation make listening difficult. The radio aid works by making the sound/speech the CYP needs to hear, such as the teacher’s voice, clearer in relation to unwanted background noise and helps to overcome the problems of hearing speech at a distance.
