Octave-band analysis can be implemented in two fundamentally different ways: FFT binning (integrating PSD/FFT bins into 1/1- and 1/3-octave bands) and a true octave filter bank (standards-oriented bandpass filters + RMS/Leq averaging). In this post, we compare how the two methods work, where their results match, where they diverge (scaling, window ENBW, band-edge weighting, latency, […]
Octave-band analysis converts detailed spectra into standardized 1/1- and 1/3-octave bands using constant-percentage bandwidth on a logarithmic frequency axis. In this post, we explain the mathematical basis of CPB, why IEC 61260-1 and ANSI S1.11 define octave bands the way they do, and how band levels are computed in practice (FFT binning vs. filter-bank RMS). […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
