BINAURAL BITHERMAL AIR CALORIC TEST. THE AIR CALORIC STIMULATOR HAS THE ADVANTAGE OF BEING ABLE TO BE USE IN THE PRESENSE OF THE TYMPANIC MEMBRANE PERFO- RATION. EACH EAR IS STIMULATED WITH 8 L OF EAR DURING 60 SEC. FOR COOL CALORIC TEST THE TEMPERATURE IS 24 DEG. AND FOR WARM STIMULATION THE TEMPERATURE IS 50 DEG. 4
