Partial discharge (PD) signals were detected in the medium-voltage switchgear of a plant, raising concerns about the safety and stability of the electrical system. To ensure safe inspection, the technical team isolated the affected area by cutting power. Corrective measures included applying high voltage from an external source to the equipment and using advanced detection [...]
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 [...]
Use our free compressed air leak cost calculator to estimate annual loss, then learn how to find and fix plant air leaks faster.
As the core component of measurement chains, the long-term stability of measuring microphones directly impacts the comparability and traceability of measurement data. The 10-year limited warranty (hereinafter referred to as the 10-year warranty) is not merely a service commitment, but a comprehensive capability demonstrated through manufacturing consistency control, reliability verification systems, and traceable evidence chains. [...]
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 [...]
Why Choosing the Right Acoustic Test Chamber Matters In electroacoustic testing and wireless device production, the test chamber is not just a box - it directly affects measurement accuracy, throughput, and production costs. The wrong chamber can introduce background noise into your measurements, fail to shield RF interference, or simply not fit your DUT (Device [...]
What Is an Anechoic Chamber? An anechoic chamber is a room designed to completely absorb sound reflections. The walls, ceiling, and (in a full anechoic chamber) the floor are lined with wedge-shaped foam or fibreglass absorbers that prevent sound waves from bouncing back into the room. The result is a controlled acoustic environment that simulates [...]
During pilot production and production line ramp-up, many issues do not appear in the way teams initially expect. Sometimes it starts with a small fluctuation at a test station, or a comment from a line engineer saying, "This result looks a bit unusual."However, when takt time, yield targets, and delivery milestones are all under pressure, [...]
