Abstract

Decades of medical examinations have shown that large-scale risks of hearing defects exist not only from 90 dB(A) upwards, but even from 85 dB(A) upwards. This experience is confirmed by the analysis of 25 000 tone threshold audiograms and by the results of experimental hearing fatigue tests.

Zusammenfassung

Wie die jahrzehntelange ärztliche Begutachtung zeigt, bestehen stärkere Hörschädigungsrisken nicht erst ab 90, sondern schon ab einem Lärmpegel von 85 dB(A). Diese Erfahrung wird durch eine Analyse von 25000 Tonschwellenaudiogrammen und durch das Ergebnis ex-perimenteller Gehöremüdungstest bestätigt.
