CRY3402 Pressure-field Microphone, 1/4″ Prepolarized, 1.6mV/Pa
CRY3402 is a 1/4-inch pressure-field prepolarized measurement microphone designed for high-frequency and high-dynamic-range acoustic measurements.
The unique design of CRY3402 provides a flat frequency response, allowing for measurement frequencies up to 70 kHz. It is also capable of withstanding sound pressure levels of up to 170 dB. This makes it an excellent general-purpose measurement microphone for high-definition audio measurements and other ultrasonic acoustic applications.
