Visual Reinforcement Audiometry


vra test Image
Assesses hearing acuity using conditioned responses to sound (i.e., head turning). Appropriate for testing children from 7 months through 30 months of age.

The child is conditioned to provide a specific response to an acoustic stimulus. For example, a head turn in the direction of the sound source is rewarded by lighting and/or activating an animated toy. Once the child is conditioned to respond to the sound, the intensity of the signal is reduced to determine threshold of hearing.

This procedure can be used to determine threshold of hearing.

Because signals are typically presented through a loudspeaker, thresholds obtained indicate acuity of the "better hearing ear."
