SonoDAQ Enclosure Coating Hardness Test

In real DAQ use, enclosure durability and scratch resistance directly affect service life and maintenance cost. This article shares a pencil hardness scratch test on the SonoDAQ top cover (PC + carbon fiber) and compares it with a typical laptop enclosure. The results show how the enclosure performs from 2H to 5H and why the [...]

Differences Between Measurement Microphones and Regular Microphones

Across acoustics testing, product R&D, environmental noise monitoring, and NVH analysis, simply "capturing sound" isn't the goal-accurate sound measurement is. A measurement microphone is engineered for repeatable, traceable, and quantifiable results, so your data stays comparable across devices, labs, and time. In this post, we explain what a measurement microphone is and how it differs [...]

Panelized PCBA Test for Multi-Product Lines

CRYSOUND's PCBA testing solution integrates RF and audio performance validation within a 1-to-8 parallel architecture, enabling synchronized electrical, RF, audio, and power testing. This unified platform enhances PCBA test efficiency and adaptability for TWS, smart speakers, and wearables, driving cost-effective, high-volume production with streamlined integration. Industry Pain Points: Challenges of Traditional PCBA Testing in Multi-Category [...]

Visualized Vacuum Leak Testing for Trains

Negative-pressure airtightness is critical for high-speed train car bodies, and even minor leaks can lead to rework or delivery risks. This article presents a case from Changchun where CRYSOUND's CRY8124 Acoustic Imaging Camera was used to quickly, intuitively, and verifiably pinpoint leaks on a carbon-fiber train car body shell, showcasing the CRY8124's application in vacuum [...]

Optimize Acoustic Test Data: Gain, Range, Quantization

In acoustic testing, sensor calibration, electroacoustics, and NVH, gain, input range, and quantization directly determine the quality of the data you capture. This article explains these three factors from an engineering perspective. Using typical CRYSOUND setups-measurement microphones, preamps, acoustic imaging systems, and DAQ system such as SonoDAQ Pro with OpenTest-it shows how to configure them [...]

Anomalous Sound Detection: From Human Ears to AI

With the rapid growth of consumer audio products such as headphones, loudspeakers and wearables, users' expectations for "good sound" have moved far beyond simply being able to hear clearly. Now they want sound that is comfortable, clean, and free from any extra rustling, clicking or scratching noises. However, in most factories, anomalous sound testing still [...]

IMU Test for Spatial Audio

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 [...]

Wind Turbine Blade Vacuum Bag Integrity Test in 10 Minutes

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 [...]

Advanced Acoustic Impedance Testing Solution for Materials

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 [...]

Sound Calibrator Explains Measurement Microphone Calibration

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 [...]

Connect Multiple DAQs and Audio Interfaces in OpenTest

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, [...]

How It Delivers Nanosecond-Level DAQ Synchronization

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 [...]
