The AWA14403 measuring microphone is designed strictly according to the specifications for standard microphones. The diaphragm uses a press-fit structure. The microphone requires external polarization power supply and has extremely high stability. Its frequency range is up to 40 kHz. It can be used as a transfer standard in the calibration of acoustic measuring instruments and is also suitable for acoustic environments with no reflections or only incident sound waves in a specific direction (such as anechoic chambers and semi-anechoic chambers).
