The Microphone That Goes Where Others Can’t.
1/2″ Prepolarized Free-Field | IP67 | –50°C to +125°C | Built for the Real World
The Problem With Traditional NVH 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 first NVH measurement microphone that delivers laboratory-grade accuracy in the harshest real-world conditions — without compromise, without babysitting, without excuses.
| What You Get | What It Means |
|---|---|
| –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 | Full immersion protection. Rain, road spray, pressure washing — it keeps measuring |
| 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 |
This isn’t an incremental improvement. It’s a new category: the ruggedized precision NVH microphone.
Why CRY3213 Is Different
1. Extreme Temperature Performance
Most measurement microphones spec a conservative operating range: 0°C to 50°C, maybe –10°C to 60°C with reduced performance. 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.
2. 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
Most competitors either lack IP ratings entirely or max out at IP55 (limited dust/splash protection). CRY3213’s IP67 is the highest protection class available in a precision NVH microphone.
3. Ruggedized and Vibration-Resistant
Traditional condenser microphones are delicate by nature — thin diaphragms, precision air gaps, tight tolerances. The CRY3213 is engineered differently:
- Shock-resistant construction — survives drops, bumps, and the everyday abuse of field testing
- Power-on LED indicator — instant visual confirmation that the microphone is active and powered
- Vibration-isolated design — rejects mechanical vibration that would contaminate acoustic measurements on engine test benches and vehicle structures
- Robust cable and connector — designed for repeated connect/disconnect cycles in field conditions
This means you can mount it on the vehicle, not just near it. Engine mounts, chassis rails, wheel arches — places where traditional microphones would fail from vibration alone.
4. 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 up 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

Frequently Asked Questions
Q: Can I use CRY3213 with my existing NVH data acquisition system?
A: Yes. CRY3213 is a prepolarized (0V) IEPE/CCP microphone, compatible with any standard constant-current input — including systems from Siemens (SCADAS), HBK (LAN-XI), Dewesoft, National Instruments, HEAD acoustics, and others.
Q: How does it handle rapid temperature changes during thermal cycling tests?
A: CRY3213 is designed for continuous operation across its full –50°C to +125°C range, including rapid transitions. The thermal compensation ensures sensitivity stability without requiring recalibration between temperature extremes.
Q: Is it suitable for permanent outdoor installation?
A: Yes. With IP67 protection, CRY3213 is suitable for long-term outdoor deployment. For extended installations, we recommend using the optional outdoor windscreen accessory to minimize wind-induced noise.
Q: What’s the advantage over array microphones for NVH?
A: Array microphones (MEMS-based) offer cost advantages for large-channel setups but typically have narrower dynamic ranges and less environmental protection. CRY3213 provides IEC 61094-compliant precision for reference-quality measurements in conditions where array microphones can’t survive.
Q: 10-year warranty — what does it cover?
A: CRYSOUND’s 10-year warranty covers manufacturing defects and sensitivity drift beyond specification. It’s one of the longest warranties in the measurement microphone industry, reflecting our confidence in CRY3213’s long-term reliability.
