title: Personal results, trial of classification and standardization in clinical impedancemetry.
abstract: The author analyzes the results obtained in clinical impedance testing of 2,799 ears by tympanometry and study of the acoustico-facial reflex. Impedance terminology is discussed and classified in an attempt to bring order to the results. Important findings include the high incidence of negative middle ear pressure in older, profoundly hard-of-hearing children.
