Zhongke Shengxuan Noise Quality Control Testing System: Industrial Manufacturing Noise Quality Control Testing
In modern industrial manufacturing, noise detection and quality control have always been critical and complex problems. In order to ensure that the noise of the product meets the standards, it is usually necessary to conduct testing in a fully anechoic chamber or a semi-anechoic chamber to obtain objective and accurate acoustic data. However, due to limitations in production line space, cost, and production cycle times, anechoic chambers cannot be applied to actual production lines, which makes it a huge challenge to accurately measure noise in actual production line environments.
Core technology highlights
Zhongke Shengxuan noise detection system has been successfully deployed on the production lines of many well-known manufacturing companies, effectively improving the accuracy and efficiency of product noise quality control. By providing comprehensive data analysis and real-time monitoring, it helps enterprises reduce errors in manual intervention and provides solid noise quality assurance for intelligent manufacturing.
Intelligent compensation algorithm
Use machine learning and deep learning algorithms such as autoencoders and convolutional neural networks to model ambient and reflected noise, and use real-time data correction to compare noise data collected in ordinary silent cabinets to ideal testing in an anechoic chamber Conditional alignment overcomes environmental limitations and data bias in production line noise measurements。
Multidimensional noise analysis function
Zhongke Shengxuan’s acoustic signal analysis software supports more than a dozen noise analysis methods, including total sound pressure level (SPL), time-varying sound pressure, one-third octave band, short-time Fourier transform (STFT), Fast Fourier Transform (FFT), loudness, sharpness, roughness, jitter, skewness, kurtosis, etc. Through the extraction and analysis of multi-dimensional features, the system can comprehensively evaluate the noise characteristics of products and provide refined noise quality control for the production line.
High-precision data collection and analysis
The system is equipped with a highly sensitive acoustic sensor and a high-speed data acquisition card, combined with advanced signal processing algorithms (such as spectrum analysis, Mel frequency cepstral coefficient (MFCC), etc.), which can accurately capture small changes in noise signals and ensure the reliability of detection results. and consistency.
Integrated design suitable for automated production lines
Zhongke Shengxuan’s noise detection solution has a simple design and is suitable for the automated processes of various industrial production lines. The silent cabinet is compact and easy to deploy, which not only saves space, but also reduces noise detection costs while ensuring data accuracy.
