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 three-axis, three-degree-of-freedom (3-DoF) rotary table. You'll learn the working principles, test flow, and application scenarios […]
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 Turbine Blade? Wind turbine blades are the key rotor components that convert wind energy into […]
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 quantify a material's ability to absorb and reflect sound, but also evaluate its performance in […]
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 the measurement chain, we should start with what it generates-and what it can (and […]
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 emerged: Hardware is not the bottleneck anymore. The real challenge is: How do you connect, […]
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 when multiple acquisition chassis are distributed across different locations and connected over a network, yet […]
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 common measurement microphone interfaces, looking at physical connectors, powering methods, cable characteristics, and typical application-driven […]
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 "one-to-one" connection relies on the Bluetooth 5.0 unicast mechanism. Its intelligence goes far beyond simple […]
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 that can truly hear. Many people still equate "hearing" with basic voice recognition, assuming it's […]
sound power
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." For typical office devices like notebook computers, idle noise is often around 30 dB(A), while […]
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 in laboratory environments or industrial sites, SonoDAQ provides efficient, accurate data acquisition solutions, maximizing the […]
