Visual reinforcement audiometry (VRA) is a key behavioural test for evaluating hearing in young children.

Conditioned orientation reflex (COR) is a variant of VRA where more than one sound is used. The key difference between COR and VRA is that COR is dependent on the child to have the ability to detect and localize the sound, whereas VRA only requires the child to have a head turn response after the auditory stimulus is presented, they do not need to accurately localize the sound as well.
