CRY3203-S02 Free-Field Microphone Set, 1/2", 50mV/Pa

CRY3203-S02 Free-Field Microphone Set, 1/2", 50mV/Pa

CRY3203-S02 is a 1/2-inch free-field prepolarized measurement microphone and preamplifier set widely used in acoustic testing environments, such as anechoic chambers and quiet rooms.

The unique design of CRY3203-S02 allows it to have a frequency response range that matches the auditory frequency range of the human ear, making it highly suitable for noise detection. Additionally, it is also widely applicable in various fields including electroacoustic measurements, audio measurements, and acoustical research.
