When validating quietness for home appliances, fans, precision motors, medical devices, transformers, and consumer electronics, we are not only asking whether a product is "loud" or "quiet." We need to know where the sound comes from, under which operating condition it appears, and in which frequency range it becomes uncomfortable. A quiet product can sometimes [...]
Wearable audio devices are becoming smaller, smarter, and more complex. From TWS / OWS earbuds, bone-conduction earphones, hearing aids, smart glasses, and smart watches or smart bands, modern wearable devices can no longer be judged only by whether their acoustic output follows a frequency response curve. In real production environments, a device may pass frequency [...]
Wind tunnels were originally built to see the flow. Within a controlled test section, engineers direct airflow at a specified velocity over vehicles, wings, UAVs, rotor blades, or scale models. By analyzing pressure distributions, aerodynamic forces and moments, smoke visualization, Particle Image Velocimetry (PIV), and balance measurements, they can determine whether flow separation occurs, drag [...]
High SPL Measurement
Learn how to select a working standard microphone for high SPL testing above 160 dB, including distortion limits, test environment requirements, THD data, and CRYSOUND microphone options.
Sound power testing is used to quantify the total acoustic energy radiated by equipment, with sound power level, Lw, as the key metric. Unlike sound pressure level, which only indicates how loud a sound is at a particular point, sound power is better suited to noise benchmarking and compliance declarations across sites, laboratories and production [...]
Explore the top acoustic imaging applications across industries, from air leak detection and partial discharge to drone inspection and NVH troubleshooting.
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 [...]
CRYSOUND's CRY2830 Series sound level meters support 24/7 data center noise monitoring, helping operators maintain noise compliance records and reduce the risk of fines. As AI workloads surge and hyperscale facilities continue to expand, data center noise complaints are rising rapidly. At the same time, environmental noise regulations are becoming more stringent. In Europe, more [...]
Traditional NVH tools still matter, but they don't cover every EV scenario-acoustic cameras fill the gap with real-time noise visualization and wide-band diagnostics. The Quiet EV Paradox: Why Electric Cars Are Actually "Noisier" It sounds like a paradox - electric vehicles have no roaring engine, yet engineers are finding it harder than ever to achieve [...]
Learn how to identify acoustic imaging false positives, ghost images, and beamforming artifacts in acoustic cameras used in noisy plants.
A measurement microphone is not just any microphone - it is a precision acoustic sensor designed for traceable, repeatable sound pressure measurement. This guide covers how they work, the different types available, key specifications to compare, and how to select the right one for your application. What Is a Measurement Microphone? A measurement microphone is [...]
Acoustic cameras turn invisible sound into visible images. This guide explains how they work, where they're used, and how to choose the right one for your application. What Is an Acoustic Camera? An acoustic camera is a device that locates and visualizes sound sources in real time. It combines a microphone array - typically 64 [...]
