CRY3213: The NVH Microphone That Goes Where Others Can't

CRY3213 is a 1/2-inch prepolarized free-field microphone engineered for NVH testing in the real world - rain, dust, engine bay heat, Arctic cold. With IP67 protection and a -50°C to +125°C operating range, it delivers lab-grade accuracy without compromise, from powertrain noise to road and wind noise measurements.

The Problem With Traditional Microphones

Every NVH engineer knows the frustration: you need accurate acoustic data, but the test environment is anything but laboratory-perfect.

Rain. Dust. Engine bay heat at 120°C. Scandinavian winter at -40°C. Vibration. Shock. Road spray.

Traditional measurement microphones weren't built for this. They're precision instruments designed for controlled environments - fragile, temperature-sensitive, and one drop away from an expensive recalibration. So engineers compromise: they protect the microphone instead of optimizing the measurement, or they accept degraded data from sensors pushed beyond their limits.

CRY3213 changes this equation entirely.

A Game Changer for NVH Testing

The CRY3213 is the NVH measurement microphone that delivers laboratory-grade accuracy in the harshest real-world conditions - without compromise, without babysitting, without excuses. This isn't an incremental improvement. It's a new category: the ruggedized precision NVH microphone.

Feature	What It Means for Your Testing
-50°C to +125°C operating range	Test in Arctic cold or next to a turbo manifold - same accuracy, same reliability
IP67 dust & water protection	Continue operating in rain, road spray, temporary water immersion, sand and dust - without extra protection
Ruggedized, vibration-resistant design	Survives the shocks and vibrations of real-world vehicle testing without signal degradation
50 mV/Pa sensitivity	High output for excellent signal-to-noise ratio, even in quiet cabin measurements
3.15 Hz - 20 kHz (±2 dB)	Full audible bandwidth plus infrasound - captures everything from tire cavity resonance to HVAC hiss

Why CRY3213 Is Different

Extreme Temperature Performance

Most measurement microphones spec a conservative operating range. That's fine for a lab. It's useless for:

• Cold climate testing in Arjeplog, Sweden (-35°C) or Northern China (-40°C)
• Under-hood measurements where temperatures routinely exceed 100°C near exhaust manifolds and turbochargers
• Thermal cycling tests that swing from frozen to furnace in minutes

CRY3213 operates at -50°C to +125°C with specified accuracy. No warm-up drift. No thermal shutdown. No recalibration needed between temperature extremes.

When your competitors are swapping frozen microphones in the parking lot, your CRY3213 is still collecting data.

IP67: Truly Weatherproof

IP67 means:
- 6 = Total dust ingress protection (dust-tight)
- 7 = Protected against temporary immersion in water (up to 1 meter, 30 minutes)

For NVH testing, this translates to:
- Pass-by noise testing in rain - no test cancellations, no scrambling for covers
- Road spray and puddle testing - mount microphones at wheel height without worry
- Tropical humidity environments - no condensation-related signal drift
- Outdoor long-term monitoring - deploy and forget

CRY3213's IP67 is the highest protection class available in a precision NVH microphone.

Ruggedized and Vibration-Resistant

Traditional condenser microphones are inherently precise and delicate. The CRY3213 has been systematically reinforced at the structural level for field durability, allowing it not only to measure near the vehicle, but also to be mounted directly on the vehicle for testing.

Shock-resistant structural design helps withstand field handling and repeated installation/removal.

Power-on LED indication enables quick confirmation of the microphone's operating status.

Vibration-isolated design helps suppress mechanical interference transmitted through test benches and vehicle structures.

The cable and connector system is designed for frequent connection, disconnection, and field deployment.

No-Compromise Acoustic Performance

Ruggedized doesn't mean reduced performance. CRY3213 delivers:

• Sensitivity: 50 mV/Pa (-26 dB re 1V/Pa) - matching premium lab microphones
• Frequency Response: 3.15 Hz to 20 kHz (±2 dB) - the full NVH bandwidth
• Dynamic range 17 to 136 dB - handles everything from quiet cabin to high-SPL engine bay measurements
• Low-frequency extension to 3.15 Hz - critical for tire cavity resonance (180-250 Hz), body boom (30-60 Hz), and powertrain low-order vibrations
• Prepolarized design - no external polarization voltage needed; plug-and-play with any IEPE/CCP input
