[High tone audiometry I. Dominant sidedness of hearing (author's transl)]

Tests for determining the dominant hearing ear by use of high tone audiometry (18 to 16 KHz) on 100 male and female "normal hearing" patients aged between 5 and 71 years of age demonstrated a relationship with whole body laterality (eye dominance, preferred tongue side, vocal cord asymmetry and hand and foot dominance). Right ear dominance was found in 62 of 85 right-handed individuals, whereas left ear dominance was found in only 3 of 10 left-handed individuals. In 5 with ambidexterity high tone audiometry failed to show any significant preference. High tone audiometry clearly clarifies cerebral hemisphere dominance and this auditory dominance can be utilized therapeutically as well as prognostically.
