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, […]
In our previous blog post, Anomalous Sound Detection: From Human Ears to AI"we discussed the key pain points of manual listening, introduced CRYSOUND's AI-based anomalous sound testing solution, outlined the training approach at a high level, and showed how the system can be deployed on a TWS production line. In this post, we take the […]
As A²B microphones and sensors are increasingly adopted in automotive applications, the demand for reliable testing in both R&D and production is also growing. This article explains why A²B testing matters, highlights the advantages of A²B over traditional analog cabling in terms of interconnect and scalability, outlines key measurement KPIs (such as frequency response, THD+N, […]
Precision measurement is only as trustworthy as the tools behind it. At CRYSOUND, long-term reliability has always been part of how we support professional acoustic testing and metrology work-especially for equipment expected to perform consistently over many years. That's why CRYSOUND provides a 10-Year Limited Warranty for eligibleCRY3000 series sensors offering long-horizon confidence for labs, […]
In many practical applications, data acquisition is not performed in an "ideal laboratory" environment. The device under test may be connected to mains power, distribution cabinets, frequency converters, or large electromechanical systems, while the acquisition card on the other side is connected via USB or Ethernet to a computer-sometimes operated directly by a person. These […]
In the fields of acoustic research and industrial inspection, sound is no longer just a signal to be "heard",but information that can be "seen". How to visualize, analyze, and quantify sound has been a long-standing pursuit for research institutions and engineers alike. Today, leveraging its deep expertise in acoustics, CRYSOUND has launched the new SonoCam […]
