NORMAL AMPLITUDE IN TRACING ON BEKESY AUDIOGRAM

[A consideration on reduced amplitude in Bekesy audiograms].

Bekesy audiograms were compared between tracings with continous and interrupted tonal stimulations, In accordance with Jerger, reduced amplitude in Bekesy tracings in cases with cochlear lesion were observed exclusively when the test was administered with continous tone, but this change was not recognized in the test with interrupted tone. On the basis of this fact, the authors came to the conc...

Wave amplitude relationships in the normal electrocardiogram.

The characteristics ofthe standard 12-lead electrocardiogram have been determined by studies based on large numbers of apparently normal subjects (Kossmann and Johnston, 1935; Myers et al., 1947; Sokolow and Friedlander, 1949; Hiss, Lamb, and Allen, 1960). Means, standard deviations, and percentile distributions have been calculated for all waves. Relationships between amplitudes of waves appea...

Georg Von Bekesy--Visualisation of Hearing.

Georg von Békésy received the Nobel Prize in 1961 for his research on the functioning of the auditory system. In psychoacoustics, Békésy both extended and perfected the lines of research begun by von Helmholtz in the 19th century. First in his native Hungary and later at Harvard, Békésy used novel and imaginative devices and methods to observe and model the functioning of the inner ear. He also...

Beyond ray tracing for internal waves. II. Finite-amplitude effects

We examine the transmission of small and moderately large internal gravity wavepackets through uniformly and nonuniformly stratified fluids using fully nonlinear numerical simulations. The simulations of finite-amplitude waves in a uniformly stratified fluid show that the weakly nonlinear theory developed for horizontally periodic wavepackets extends well to the dynamics of wavepackets with hor...
