AWA14411 1" Prepolarized Free-Field Low-Noise Measurement Microphone

The AWA14411 prepolarized free-field low-noise measurement microphone features a large 18 mm diaphragm size and an ultra-low noise floor of 6.5 dBA, meeting the needs of various low-sound-level measurements. 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 frequency range of 10 Hz to 16 kHz, high sensitivity, and strong stability. The microphone supports connection to mainstream acoustic analysis instruments and is widely used in low-sound-level measurement, sound power measurement, automotive NVH evaluation, and other fields.
