Ziel der vorliegenden Studie war die prospektive Erhebung audiometrischer Kenndaten f\u00fcr Normalh\u00f6rigkeit, welche nicht nur auf der Tonaudiometrie basiert, sondern mit objektiven Daten zur Mittelohrfunktion erg\u00e4nzt wurden.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methode<\/jats:title>\n                    <jats:p>Die Untersuchungen wurden an 84\u00a0Ohren tonaudiometrisch normalh\u00f6render Proband*innen im Alter zwischen 18\u00a0und 25\u00a0Jahren durchgef\u00fchrt. Die objektive Mittelohrdiagnostik erfolgte unter Verwendung der klassischen Tympanometrie, der Breitband-Absorbanz-Tympanometrie und der Stapediusreflexschwellenmessung. Erg\u00e4nzend wurde eine Messung der\u00a0distorsiv\u00a0produzierten otoakustischen Emissionen (DPOAE) durchgef\u00fchrt.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ergebnisse<\/jats:title>\n                    <jats:p>Bei 7\u00a0der 84 untersuchten Ohren fand sich eine Compliance von mehr als 2\u202fmmho. Erg\u00e4nzend zu den normalh\u00f6renden Ohren wurden diese im Weiteren separat betrachtet. Die Resonanzfrequenz dieser sieben Ohren lag unterhalb des ersten Quartils der Vergleichsgruppe (759\u202fHz), und die Absorbanz dieser Gruppe befand sich f\u00fcr Frequenzen bis 750 \u00fcber dem 3.\u00a0Quartil der Absorbanz f\u00fcr die Gruppe mit regul\u00e4rer Compliance. In der Gruppe mit erh\u00f6hter Compliance waren in mehr F\u00e4llen als in der Vergleichsgruppe (14\u202f% vs.\u00a05\u202f%)bei mind. einer Frequenz keine DPOAE nachweisbar. Bei 6\u00a0der 7\u00a0Ohren mit erh\u00f6hter Compliance fanden sich in allen gemessenen Frequenzen Stapediusreflexschwellen im Bereich der Whisker der Gruppe mit regul\u00e4rer Compliance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Schlussfolgerung<\/jats:title>\n                    <jats:p>In der DIN-Norm zur Klassifizierung von Normalh\u00f6rigkeit besteht die Definition der Normalh\u00f6rigkeit allein aufgrund tonaudiometrischer Parametrisierung.
