AWA14423C 1/2" Prepolarized Free-Field Infrasound Sensor

The AWA14423C prepolarized free-field infrasound sensor is designed specifically for infrasound measurement scenarios, but can also be used for 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-low frequency limit of 0.1 Hz, 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 building acoustic assessment.
