AWA14523 1/2" Prepolarized Free-Field Infrasound Broadband Sensor

The AWA14523 prepolarized free-field infrasound broadband sensor is designed for both infrasound and ultrasonic measurement scenarios and conventional acoustic measurements. It includes an independent calibration certificate and is suitable for acoustic environments with no reflection or only incident sound waves in a specific direction (such as anechoic chambers and semi-anechoic chambers). It features an ultra-wide frequency range of 0.1 Hz to 40 kHz, high sensitivity, and strong stability. It supports connection to mainstream acoustic analysis instruments and is widely used in infrasound measurement, noise source localization, equipment acoustic performance testing, and architectural acoustic assessment.
