Why Choosing the Right Acoustic Test Chamber Matters In electroacoustic testing and wireless device production, the test chamber is not just a box - it directly affects measurement accuracy, throughput, and production costs. The wrong chamber can introduce background noise into your measurements, fail to shield RF interference, or simply not fit your DUT (Device […]
What Is an Anechoic Chamber? An anechoic chamber is a room designed to completely absorb sound reflections. The walls, ceiling, and (in a full anechoic chamber) the floor are lined with wedge-shaped foam or fibreglass absorbers that prevent sound waves from bouncing back into the room. The result is a controlled acoustic environment that simulates […]
During pilot production and production line ramp-up, many issues do not appear in the way teams initially expect. Sometimes it starts with a small fluctuation at a test station, or a comment from a line engineer saying, "This result looks a bit unusual."However, when takt time, yield targets, and delivery milestones are all under pressure, […]
In our previous blog post, Anomalous Sound Detection: From Human Ears to AI"we discussed the key pain points of manual listening, introduced CRYSOUND's AI-based anomalous sound testing solution, outlined the training approach at a high level, and showed how the system can be deployed on a TWS production line. In this post, we take the […]
As A²B microphones and sensors are increasingly adopted in automotive applications, the demand for reliable testing in both R&D and production is also growing. This article explains why A²B testing matters, highlights the advantages of A²B over traditional analog cabling in terms of interconnect and scalability, outlines key measurement KPIs (such as frequency response, THD+N, […]
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, […]
In many practical applications, data acquisition is not performed in an "ideal laboratory" environment. The device under test may be connected to mains power, distribution cabinets, frequency converters, or large electromechanical systems, while the acquisition card on the other side is connected via USB or Ethernet to a computer-sometimes operated directly by a person. These […]
In the fields of acoustic research and industrial inspection, sound is no longer just a signal to be "heard",but information that can be "seen". How to visualize, analyze, and quantify sound has been a long-standing pursuit for research institutions and engineers alike. Today, leveraging its deep expertise in acoustics, CRYSOUND has launched the new SonoCam […]
A2DP (Advanced Audio Distribution Profile) is the core Classic Bluetooth profile for high-quality audio streaming. This article provides an overview of how A2DP transmits music, explains its position in the Bluetooth protocol stack, and introduces a practical A2DP testing workflow using the CRY578 Bluetooth LE Audio Interface. How Does A2DP Transmit Music? A2DP is the […]
Sound is everywhere in our daily life: birdsong, street noise, engine roar, even the faint airflow from an air conditioner. For people, sound is not only about whether we can hear it, but whether it feels comfortable, is disturbing, or poses a risk. The same 70 dB can feel completely different; and when something feels […]
Valves are the "core control components" of pipeline systems. They perform four key functions-opening/closing, regulating, isolating, and directing-enabling precise control of fluid flow. Once sealing integrity fails, minor cases can lead to process upsets and energy losses, while severe cases may result in fires or explosions, toxic exposure, or environmental pollution. We built a valve […]
Sound Level Meter
This article presents a multi-channel sound level meter developed on the OpenTest platform and designed to meet the technical requirements of IEC 61672-1. By integrating the SonoDAQ data acquisition system with measurement-grade microphones, the system implements standard A/C/Z frequency weightings, F/S/I time weightings, and enables accurate measurement of standard acoustic quantities such as Lp, Leq, […]
