Abstract

Bei einem Richtmikrofonsystem zweiter oder höherer Ordnung mit wenigstens drei omnidirektionalen Mikrofonen (21, 22, 23; 55, 56, 57) soll ein Mikrofonabgleich durchgeführt werden. In einem ersten Verfahrensschritt werden die Signalpegel der von den drei omnidirektionalen Mikrofonen (21, 22, 23; 55, 56, 57) erzeugten Mikrofonsignale abgeglichen. Anschließend wird die Phase bei einem der drei Mikrofonsignale so lange variiert, bis auch die Signalpegel von Richtmikrofonen erster Ordnung, die aus den drei omnidirektionalen Mikrofonen gebildet werden, abgeglichen sind.
