CRY3408-S01 Pressure-field Prepolarized High-level Microphone Set, 1/4", 0.14mV/Pa
CRY3408-S01 is a 1/4-inch pressure-field prepolarized measurement microphone set specifically designed for acoustic measurements in high sound pressure level environments. It can operate without distortion at sound pressure levels up to 180 dB SPL, delivering stable and reliable measurement data even in conditions where standard measurement microphones may be unsuitable or prone to overload.
From high-power equipment testing to industrial blasting, impulsive noise, and other extremely high-SPL environments, the CRY3408-S01 accurately captures critical acoustic data under conditions that can overload conventional measurement microphones. It is well suited for high-SPL noise testing, industrial acoustic measurements, impulsive noise analysis, and noise testing of large equipment.

Product Highlights
Purpose-Built for High-SPL Measurements
The CRY3408-S01 is specifically engineered for acoustic measurements in extreme high-SPL environments, with the capability to withstand sound pressure levels of up to 180 dB SPL. Its low sensitivity of 0.14 mV/Pa is optimized for ultra-high-SPL measurements, allowing the output to remain within the usable input range of the acquisition system even under 170-180 dB conditions. This helps prevent clipping and distortion that commonly occur with conventional microphones at such levels, ensuring more accurate and reliable measurement data. Whether for blast shock, impulse noise, airbag deployment, or gunshot testing, the CRY3408-S01 provides a stable and dependable solution.
Small-Diameter Design for Minimal Sound Field Disturbance
The CRY3408-S01 features a 1/4-inch microphone design that helps minimize disturbance to the original sound field during testing, enabling more accurate and representative measurement results. Compared with larger microphones, its compact sensing element offers clear advantages in high-frequency measurements, near-field testing, and space-constrained setups, while also reducing reflections and obstructions caused by the microphone body itself. This makes it particularly suitable for precision acoustic measurements where sound field fidelity is critical.
Easier Deployment in Demanding Test Setups
With its compact 1/4-inch form factor and prepolarized design, the CRY3408-S01 eliminates the need for an external 200 V polarization supply. It is compatible with IEPE/CCP/ICP powering, making it easier to integrate into both field and laboratory measurement chains. This makes it especially suitable for space-constrained and harsh test environments, such as turbine facilities, heavy manufacturing, DFAT systems, and aerospace acoustic fatigue testing.

10-Year Warranty
The CRY3408 measurement microphone is backed by a 10-year limited warranty from CRYSOUND. For details, please refer to the applicable warranty terms and service policy.
CRYSOUND recommends that the microphone be calibrated annually, with an additional calibration performed after exposure to extreme test environments.
