Mikrofonkapseln

Die Mikrofonkapseln von Brüel & Kjaer eignen sich für eine Vielzahl von Messanwendungen. Vier Arten von Mikrofonen definieren das Schallfeld und die Anpassungsfähigkeit an bestimmte Umgebungen, Branchen und Messbedingungen: sie werden als Freifeld-, Druckfeld-, Diffusfeld- und Spezialmikrofone bezeichnet. Mikrofonkapseln von Brüel & Kjær sind mit Durchmessern von 1 Zoll, 1/2 Zoll, 1/4 Zoll oder 1/8 Zoll erhältlich und benötigen einen Mikrofonvorverstärker.
