VRA apply to the hearing test of infant that range of seven months - 2.5 years age.Through the VRA test, make the child set up conditioned reflex of stimulation sound,and attract children turn to flash toys that reward at the same time. Use directional reflection, motivate childrencan continue to head to the direction of sound source even stimulus itself no longer interesting.

VAR complete the test through the stimulation of children.In the condition of sound field, after giving sound, the children can reflex to looking for sound source, at this moment,it will start visual reinforcement signal to reward. It is suitable for 6 months to 3 years old children.Through VAR, children are more likely to cooperate, have more accurate reaction, hearing threshold value that measured would closer to the true level.
