Measure Sound Better
Pain Points in Vacuum Testing of Composite Materials: How Can Visual Vacuum Leak Detectors Break Through？ In high-precision and cutting-edge fields such as aerospace, wind power, and rail transit, the vacuum infusion process for composite materials is hailed as the…
When we use Bluetooth headphones to listen to music, we rarely stop to consider what is happening behind the scenes. How does music stream smoothly and reliably? How do buttons instantly control playback? And how does the system seamlessly switch…
CRYSOUND leverages its mature electro-acoustic testing technologies and extensive experience in automated testing to deliver a complete smart speaker audio test solution.
Evaluating a measurement microphone kit means systematically determining—across compatibility, calibration and maintenance, spares planning, and life-cycle cost—whether a given kit fits your measurement chain and long-term usage goals. This article covers interface and powering matching, sensitivity and frequency-response specifications, calibration…
The 580 A2B is a bridging interface device for testing and validating the A²B in-vehicle audio bus. It decodes audio from A²B nodes and outputs it as analog and/or digital audio for acquisition and analysis by external instruments. This article…

The 580 A2B is a bridging interface device used to test and validate in-vehicle A²B audio buses. It decodes audio from A²B nodes and outputs it in analog and/or digital audio formats for acquisition and analysis by external instruments. This…
A2DP (Advanced Audio Distribution Profile) is the protocol used for playing music through Bluetooth headphones and similar devices. It defines how high-quality audio is transmitted from a mobile phone (the Source) to a headset (the Sink), making it a critical…
In noisy environments, selecting the correct test frequency is critical. If the right frequency range isn’t chosen, many key leakage points and partial discharge (PD) sources—often with serious safety risks—may go undetected, posing a threat to safe operations. To address…
In acoustic measurement, “microphone size” (1 inch, 1/2 inch, 1/4 inch, 1/8 inch) is not a cosmetic choice. It directly drives three practical limits of your measurement chain: This blog summarizes the typical characteristics of each size and provides a…
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…
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…
