[Significance of deviations in hearing thresholds in pure-tone audiograms]. / Zur Signifikanz von Abweichungen der Hörschwellen im Tonschwellenaudiogramm.

ABSTRACT

Variations in tone hearing thresholds can occur with a certain probability at random or due to systematic changes in hearing, the test system or the test methodology. Therefore, a significance analysis is essential for diagnostic statements and expert opinions. The random probability tables published here can be used in a simple way to identify any significant alterations in hearing thresholds with a probability of error of ≤0.05.
