Clear voice communication is crucial in aviation environments, where engine noise, cabin vibrations, and air turbulence can interfere with speech. The ECM-DM1458T200 is designed specifically for aviation headsets and other head-worn microphone applications, ensuring voices are captured clearly while background noise is minimized. Its unidirectional pickup and close-range performance make it an ideal choice for reliable in-flight communication. Key Specifications Specification Details Model ECM-DM1458T200 Dimensions 14.5 \u00d7 7.5 mm Directivity Unidirectional (typical for dynamic microphones) Sensitivity -65dB \u00b13 Impedance 200\u03a9 Frequency Response 100Hz ~ 9kHz Frequency Response and Performance The ECM-DM1458T200 is tuned to enhance speech intelligibility. Its response starts at 100Hz, reducing low-frequency background noise like engine hum and cabin vibrations.
