The distraction test is ideally used for babies who are developmentally six to eight months old (although it can be used from six months to 24 months of age by experienced testers), and assesses the ability of the baby to hear a sound then turn to locate it.
The sounds are produced to the right or left behind the baby out of their field of view. Various sound stimuli are used such as rattles, voice, drum and warble tones. The loudness of the sounds produced are varied to try and establish the minimum level that the baby is able to hear.
