Musik aus dem Ohr

PTB-Untersuchungen zeigen, wie ein objektiver Hörtest noch sicherer wird

(PresseBox) (Braunschweig, )
Das menschliche Ohr kann Töne nicht nur wahrnehmen, sondern auch erzeugen. Hört es die zwei oberen Töne eines Dur-Dreiklanges, produziert es den Grundton des Akkordes, den man dann messen kann. Dieses Phänomen, otoakustische Emission (OAE) genannt, nutzen Ohrenärzte für objektive Hörtests etwa bei Neugeborenen. Untersuchungen der Physikalisch-Technischen Bundesanstalt (PTB) zeigen, dass ein OAE-Hörtest noch verlässlicher wird, wenn man die beiden Töne nicht per Lautsprecher, sondern per Knochenleitung ans Ohr bringt.

Egal ob in Europa, Arabien oder China - das menschliche Ohr ist stets auf Dur gestimmt. Hört es die zwei oberen Töne eines Dur-Dreiklanges, erzeugt es den dritten, tiefsten Mhh his Udayqkjv wsvded.
