The phenomenon called "orientation reflex" is not a learned response, but a natural reflex movement elicited by sound or visual stimulation. if the sound visual stimulation elicits a reflex, and the reflex is conditioned by a tone, the child will look towards the visual stimulation, e.g.flashing light; as soon as the tone is heard. if the co conditioning effective the child will look in the direction of the sound source, even before the visual stimulation is presented. the COR method is based on co-operation with the child.VRATESTThe DIGITAL pediatric audiometer AP-2 can perform visual reinforcement audiometry (Liden and kankkunen 1969), which is extension and modification of COR, where the co-operation with the child is less important. Liden and kankkunen accept not oniy the sound localization orientation reflex but also four other reactions; reflex reactions (body and face), search reaction, orientation and spontaneous reactions.APRTESTThe DIGITAL pediatric audiometer AP - 2 can also elicit the Auro palperal reflex (APR) which is a contraction of the muscles surrounding the eyes. The preferred stimulation is 4000 Hz warble tone. 80 db HL intensity level is normal sufficient for most sleeping infants (Downs and steritt, 1967)INSTRUMENT CONDITIONINGWhen the child has reached age of two to three years, the so called instrument conditioning in testing children can be used i.e.teaching the child to react in certain way on sound stimuli. For this purpose ARPHI has "peep-show" toy based on play-audiometry.TECHNICAL SPECIFICATIONSDigital selection of frequencyDigital selection of AttenuationLIGHT stimulation3 LEDs arranged in a triangle, flash-speed 5 Hz FREQUENCIES500,1000,2000,4000 Hz warble toneIDENTITIES90,70,50 And 30db free filed hearing loss at 16 cms. and 80,60,40 and 20db free filed hearing loss at 50 cms.
