What is visual reinforcement audiometry? VRA, is a type of pure tone hearing test. It uses visual stimuli in conjunction with sounds to get the attention of young patients. Who needs VRA? Standard hearing tests that use headphones and feedback buttons are too complex for very young kids. VRA is used on infants and children aged 6 months to between 2 and 3 years. Where does VRA take place? Visual reinforcement audiometry requires specialized devices and a soundproof room. It is typically performed by an audiologist in an ear, nose and throat (ENT) clinic. What equipment is used for VRA? VRA uses a standard audiometer modified with earphones or sound field speakers.
