Measure Sound Better
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…
With the development of technology and industry, acoustic technology has become increasingly mature and is now widely used in areas ranging from consumer electronics to aerospace, and from medical facilities to scientific research. In various industrial inspection scenarios, equipment maintenance,…
For a long time, many engineers have seen sound calibrators as nothing more than little boxes that output 1 kHz at 94 dB: single-function devices, sensitive to the environment, not particularly pleasant to use in the field—yet still an indispensable…
Electric motors are widely used in modern automobiles and home appliances (such as in-vehicle electric seats and appliance fans), and their smooth operation directly affects product quality and user experience. Motor noise issues are often summarized as BSR (Buzz, Squeak,…
In audio and vibration testing, engineering teams often find themselves jumping between multiple software tools and data acquisition systems from different vendors. Interfaces vary, workflows are fragmented, and new engineers can spend a significant amount of time just learning the…
The all-new OpenTest website (opentest.com) is live, bringing product capabilities, ecosystem, docs, updates, and download into a single, streamlined experience to help engineers, researchers, and manufacturers get productive fast. At a Glance Bulit for Engineers Three Work Modes Key Capabilities…
