Visual reinforcement audiometry (VRA) is a key behavioural test for evaluating hearing in young children.
Performed by an audiologist, VRA is the preferred behavioral technique for children that are 6 – 24 months of age.
The results from the audiogram, paired with other objective measures such as a Tympanogram, Otoacoustic emissions testing and/or Auditory Brainstem Response testing can provide further insight into the child's auditory hearing status as well as future treatment plans if deemed necessary.
Above 18–24 months of age, children need more interesting tasks to hold their attention, which is when audiologists introduce Conditioned Play Audiometry.
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.
