ARRAY-MIKROFON (20 KHZ)
Präpolarisiertes Array-Mikrofon zur Verwendung in Systemen, die eine große Anzahl von Mikrofonen benötigen, z. B. Beamforming-Arrays, STSF-Messungen und instationäre STSF-Messungen.
TYPE 4957
Array-MikrofoneType 4957 wird in Kombination mit anderen Array-Mikrofonen verwendet und ist für eine spezifizierte und stabile Phasenanpassung über weite Temperatur- und Feuchtigkeitsbereiche konzipiert.
Ein robustes Schutzgitter sorgt für einen integrierten Hitzeschild. Das Mikrofon ist zum Druckausgleich an der Vorderseite belüftet.
