Electroacoustic Analysis System
Electroacoustic Analysis System
The CRY6125 Electroacoustic Tester is a comprehensive device designed to assess the performance of various electroacoustic components while resisting environmental noise. It measures a wide range of indicators, including sensitivity (SPL), impedance, total harmonic distortion (THD), resonance frequency (F0), quality factor (Q), equivalent volume, and audio power amplifier characteristics. Suitable for testing microphones, electret microphones, transmitters, receivers, earphones, headset microphone assemblies, communication helmets, speakers, buzzers, and more, the CRY6125 offers measurement frequencies ranging from 10 Hz to 65 kHz.
