AWA14431 1/4" Prepolarized Free-Field Wideband Measurement Microphone

The AWA14431 prepolarized free-field wideband measurement microphone is designed for free-field acoustic measurement scenarios. It includes an independent calibration certificate and is suitable for acoustic environments with no reflections or only incident sound waves in a specific direction (such as anechoic chambers and semi-anechoic chambers). It features a flat frequency response of 3.15~80 kHz, can withstand sound pressure levels up to 165 dB, and is characterized by its compact size and high stability. The kit supports connection to mainstream acoustic analysis instruments and is widely used in noise source localization, equipment acoustic performance testing, ultrasonic testing, and other fields.
