Measure Sound Better
Spatial audio performance can vary significantly across devices—even when similar audio algorithms are used. This article explains the role of the IMU in spatial audio, outlines key IMU testing challenges, and introduces CRYSOUND’s production-ready IMU testing solution based on a…
In this article, we use a wind turbine blade factory as an example to show how CRY8124 Acoustic Imaging Camera can help complete a vacuum (negative-pressure) integrity test for a single blade in about 10 minutes. What Is a Wind…
In acoustic design and noise control, a material’s acoustic impedance characteristics are a key factor in determining “how it sounds.” By measuring parameters such as the absorption coefficient, reflection coefficient, specific acoustic impedance, and acoustic admittance, we can not only…
In day-to-day acoustic measurements, it’s common to hear: “Insert the measurement microphone into the calibrator, press the button, and the microphone is calibrated.” From an engineering and metrology perspective, that wording is an oversimplification. To place a sound calibrator correctly…
In industrial testing, research, and quality validation, data acquisition devices (DAQs / audio interfaces / measurement microphone front-ends) are the “front door” of the entire system. As technology and applications become more specialized, a wide variety of DAQ devices has…
In audio and NVH testing, keeping signals aligned in time is often harder than increasing channel count or resolution. With a single chassis, synchronizing several dozen or even a hundred channels is no longer a big challenge. What really hurts is…
From the outside, a measurement microphone looks deceptively simple. But in real-world engineering, its interface options are surprisingly diverse: Lemo, BNC, Microdot, 10-32 UNF, M5, SMB… Many newcomers to acoustics ask questions like: This article provides a structured overview of…
How does your phone instantly and accurately connect to your earphones instead of someone else’s in a room full of Bluetooth devices? Why does your smart fitness band sync data exclusively to your phone app after a workout? This dedicated…
As smart devices continue to evolve, conversations about AI often revolve around visual perception, language models, or generative capabilities. Yet as devices become more immersive and more deeply embedded in our physical world, expectations are shifting—from machines that can see to machines…
Under regulations such as the EU Machinery Noise Directive, more and more products—from toys and power tools to IT equipment—are required to declare their sound power level on labels and in documentation, rather than simply claiming they are “quiet enough.”…
In sound and vibration testing, flexibility is a decisive factor—especially when test requirements evolve rapidly. SonoDAQ, with its modular, scalable architecture, helps users easily manage everything from simple tests with a single device to complex, large-scale, multi-channel data acquisition. Whether…
SonoDAQ is the next-generation high-performance data acquisition system, specifically designed for sound and vibration testing. It features a modular architecture, making data acquisition more efficient and precise. From industrial environments to laboratory measurements, SonoDAQ meets the demands of high-precision data…
