As industrial facilities continue to face increasing safety challenges in hazardous areas, continuous and reliable monitoring has become essential for preventing leaks, equipment failures, and potential safety risks. CRYSOUND is proud to announce the official launch of the new CRY2624M Ex Fixed Acoustic Imager, a next-generation solution designed for continuous acoustic monitoring in hazardous industrial [...]
OpenTest v2.1.0 Beta is now available as the August release. This update adds sensor database management, math-based virtual channels, Zoom FFT, stepped level sweep, trigger-controlled measurement, synchronized measurement across multiple modules, extended post-processing, and enhanced cursor tools to improve acoustic, NVH, and electroacoustic testing workflows. In acoustic, NVH, and electroacoustic testing, engineers often work with [...]
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, [...]
Dynamic range, noise floor, and input range describe different limits of a data acquisition system. Input range sets the maximum measurable signal, input-referred noise constrains the minimum resolvable signal, and dynamic range expresses the span between them. This article explains how to compare these specifications under consistent measurement conditions. In the specification sheets of data [...]
Professional audio interfaces, audio analyzers, and data acquisition systems can all capture signals, but they are designed for different measurement tasks. This guide compares their interfaces, measurement capabilities, synchronization, sensor support, and typical applications so engineers can choose the right platform for each test. Scope Definition: In this article, a data acquisition system refers to [...]
HVAC Leak Detection
HVAC problems often start as sounds: leaking duct seams, noisy valves, fan faults, refrigerant leak indications, and cooling issues around data centers. See how acoustic imaging helps teams locate, verify, repair, and document problems faster.
Learn how to build a repeatable acoustic imaging walkdown for leak detection, PD screening, HVAC troubleshooting, reporting, and repair verification.
How do CRYSOUND measurement microphones and calibrators perform when independently tested against established reference equipment-and pushed beyond typical laboratory conditions? In the September 2026 issue of audioXpress, technology consultant and long-time audio equipment designer Stuart Yaniger conducted a hands-on review of three CRYSOUND products: The review covered calibration accuracy, frequency response, environmental stability, self-noise, ruggedness, and [...]
Some fans do not sound very loud, yet they may still feel sharp, buzzing, or annoying over time. Others can run continuously without drawing much attention. This difference is not determined by decibels alone. It is also related to frequency distribution, tonal components, loudness, sharpness, roughness, and fluctuation strength. Using fan noise as an example, [...]
Learn how CRYSOUND combines AI listening, acoustic fixtures, OpenTest software, and production data for headphone defect detection at end of line.
In multichannel acoustic testing, entering microphone model numbers, sensitivities, and calibration data one channel at a time is slow and prone to error. TEDS allows a data acquisition system to read key parameters stored in a microphone or preamplifier, helping engineers configure channels faster and maintain consistent test settings. This article tests the CRYSOUND CRY3203-S01 [...]
Many acoustic laboratories, automotive NVH teams, consumer-electronics developers and third-party testing organizations already operate measurement systems built around HBK/Brüel & Kjær, GRAS or PCB Piezotronics products. When existing systems need more channels, replacement sensors, shorter procurement cycles or a complete platform update, engineers often ask a practical question: Which CRYSOUND products should be evaluated against [...]
