Abstract

Der Dynamikbereich von Hörgeräten soll verbessert werden. Daher wird eine Kombination aus einem Silizium-Mikrofon (SM) und einem Elektretmikrofon (EM) für den Hörgeräteeingang eingesetzt. Damit können die tiefen Frequenzen von dem Silizium-Mikrofon (SM) und die hohen Frequenzen von dem Elektretmikrofon (EM) aufgenommen werden, um ein breitbandiges Hörgeräte-Eingangssignal zu erzeugen. Auf diese Weise lässt sich der Vorteil eines Silizium-Mikrofons ausnutzen, das bei niedrigen Frequenzen ein geringeres Eigenrauschen besitzt als ein herkömmliches Elektretmikrofon.
