[The audio-visually determined reaction evaluation test (A-V-R test) (a hearing test for infants and small children)]

Abstract: The A-V-R-test is accomplished in a free sound field, either with a play audio-metric table (clinical use) or with a textile paravent (practice). The main effort of this reactiontest is the auditive-visual determination. The examiner provokes the auditive readiness with a supraliminal impulse, which prepares the starting position for offering an acoustic test impulse in a low signal strength on the left or right side. If the test is realized with the textile paravent, frequency and intensity proved music instruments or other sound producing objects (bunch of keys, Ewing-rattle, etc.) are offered to the child. If the A- V-R-test is accomplished with the play-audio-metric table, the tester presents a frequency specific narrow band noise to the examinee. Only the turn of the infant's head towards the source of the sound is evaluated. Infants older than 2 years may show specific reactions, depending on the stage of their development.
