CRY3282 Pressure-field Microphone, 1/2″, External-polarized, 12.5mV/Pa
CRY3282 is a 1/2-inch externally polarized measurement microphone designed for pressure field measurements. It is specifically designed to be used in conjunction with a coupler chamber for related electroacoustic testing.
The unique design of CRY3282 enables high-quality and wide-frequency response testing of in-ear monitors and earplugs. Its frequency range extends up to 20kHz, surpassing the testing capabilities of most simulated ears.
