An investigation on the maturation of hearing abilities in children.
A number of pure-tone tests were presented to 8 groups of children of different ages who had no ear, nose, and throat pathology and a normal I.Q., in order to investigate the degree of maturation of their hearing abilities. The Luescher test (identification of difference limen or intensity) showed a significant relationship between increasing age and precise identification of gradually decreasing levels of intensity. Performance on this test was shown to be very reliable in children, and may be used as an indication of the degree of physiological maturation of hearing abilities.
