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, [...]
Sound Power Testing
In modern metrology labs, accurately measuring product noise requires more than just sound pressure values. This case study demonstrates how a metrology institute implemented a repeatable, multi-point sound power testing workflow using SonoDAQ Pro and OpenTest, enabling reliable comparison of servers, fans, home appliances, and motors under different operating conditions. Learn how synchronized data acquisition, [...]
The CRY8020 Series SonoCam Pocket Acoustic Camera has officially launched. Designed by CRYSOUND for daily walkdowns, SonoCam Pocket brings acoustic imaging, leak detection, and partial discharge screening into a lighter field workflow, helping inspection teams locate abnormal sound sources faster and support follow-up decisions with visual evidence. The goal is simple: make acoustic imaging easier [...]
This guide helps users quickly set up and perform sound power testing using a hemispherical sound power test frame, the SonoDAQ Pro data acquisition front-end unit, and OpenTest. Stage Completion Criteria 1. Frame installation The hexagonal base is stable, the 6 arc tubes are tightened, and the top cover is secured without shaking. 2. Microphone [...]
Using a wired headphone acoustic measurement workflow as an example, this article explains how OpenTest connects to an NI USB-4431 DAQ device and supports a complete acoustic test workflow, from test setup, channel configuration, and signal acquisition to frequency response analysis, distortion analysis, report generation, and sequence-based automation. The workflow helps engineering teams upgrade their [...]
In today's rapidly evolving electroacoustic product landscape, production line testing systems are no longer expected to simply "produce measurements." They must balance test capability, throughput, stability, and scalability. Core metrics such as frequency response, distortion, and sweep analysis remain essential. At the same time, more advanced requirements, such as anomalous sound detection, multi-channel synchronization, automated [...]
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 [...]
A practical, repeatable workflow for production and lab teams-covering calibration, RF measurements, pass/fail limits, and automated reporting. Frequency Calibration and Bluetooth Performance Testing Test System: QuickRadio + MT8852B Bluetooth Tester QuickRadio provides a powerful platform that can test RF front-end interactions. QuickRadio supports multiple preconfigured sequence templates, making it easy to customize RF test workflows [...]
The audio quality of Bluetooth products is critical, yet traditional manual testing is inefficient and inconsistent. To address this, we leverage the secondary development capabilities of the CRY578 to deliver an efficient, programmable, and automated testing solution. Core Tool: CRY578 Interface Overview The CRY578 is a hardware interface specifically designed for audio testing. It functions [...]
Explore the top acoustic imaging applications across industries, from air leak detection and partial discharge to drone inspection and NVH troubleshooting.
OpenTest releases a new version every month, with the goal of ensuring that each update introduces features that truly matter to users while making the software better and faster with every release. OpenTest v1.4.0 Beta is now available, bringing updates across signal generation, hardware compatibility, new algorithms, feature improvements, and a simpler licensing experience: Why [...]
