title: [Analyses of objectifiable ear noises].
abstract: The clinical aspects and therapeutical possibilities are presented for two extremely different cases of objectifiable noises in the ears. A specific experimental method (earphones and bone conductor served as microphones) permitted a stereophonic recording. After several amplifications it was possible to tape the noises. By means of two-ray-oscillography and time extension it was possible to analyze the structure of the noises in various ways (oscillogram, synchrony, etc.) Furthermore, sonagraphic analyses of the traditional type as well as isobar sonagraphy were performed. The results achieved were surprising and completely new: It was possible to clearly present, besides typical sound superimpositions, partial tones of varying intensity in sine form up to the 1,5000 Hz range.
