In the field of acoustic measurement,the noise level of the testing environment has a crucial impact on the accuracy of measurement results.Zhongke Shengxuan,with its exceptional technical capabilities and innovative spirit,has successfully developed the Silent Test Chamber,a leading acoustic measurement device that provides an ultra-low noise testing environment for precise acoustic measurements.This advancement helps enterprises enhance product quality and R&D efficiency.
I.Core Advantages of the Silent Test Chamber
(1)Ultra-Low Noise Background
Zhongke Shengxuan’s Silent Test Chamber employs advanced sound insulation technology and high-quality materials.It can reduce the internal noise level to below 10 decibels,even in an external noise environment of up to 75 decibels.This ultra-low noise background provides an ideal testing environment for acoustic measurements,ensuring the high precision and reliability of measurement data.
(2)Wideband Free-Field Acoustic Field
The interior of the Silent Test Chamber is designed with special acoustic features that create a wideband free-field acoustic field.This means that during testing,sound waves can propagate freely inside the chamber without being affected by reflections or interferences.As a result,it provides more accurate acoustic field conditions for acoustic measurements.
(3)Intelligent Detection System
Zhongke Shengxuan’s Silent Test Chamber is equipped with highly sensitive acoustic sensors and advanced data acquisition systems.Combined with AI-based machine audition technology and deep learning algorithms,the chamber can accurately capture subtle noise variations and analyze noise signals in real-time.This intelligent detection system not only improves detection efficiency but also automatically identifies and classifies noise sources,providing scientific evidence for subsequent noise optimization.
II.Application Scenarios of the Silent Test Chamber
(1)Noise Detection of Home Appliances
In the home appliance manufacturing sector,such as in the noise detection of rice cookers,vacuum cleaners,and air conditioners,the Silent Test Chamber provides a high-precision testing environment.Through accurate noise measurement,enterprises can optimize product design,reduce noise levels,and enhance user experience.
(2)Noise Detection of Automotive Components
Noise detection of automotive components is an important part of automobile manufacturing.Zhongke Shengxuan’s Silent Test Chamber can effectively isolate external noise,providing a stable testing environment for the noise detection of automotive components.This helps enterprises identify potential noise issues in advance,optimize component design,and improve the overall quietness of the vehicle.
(3)Noise Detection of 3C Products
The noise detection of 3C products(computers,communications,and consumer electronics)requires high-precision measurement equipment.The Silent Test Chamber meets the noise detection needs of 3C products in the context of miniaturization and high performance.It helps enterprises enhance product quality and strengthen market competitiveness.
III.Technical Highlights of the Silent Test Chamber
(1)Intelligent Compensation Algorithm
The Silent Test Chamber uses an intelligent compensation algorithm that can model and correct environmental and reflective noise.Even in complex industrial production environments,the chamber ensures the accuracy and consistency of measurement data.The application of this algorithm significantly improves the reliability and efficiency of testing.
(2)Multi-Dimensional Noise Analysis
The Silent Test Chamber supports various noise analysis methods,including sound pressure level,spectral analysis,Short-Time Fourier Transform(STFT),and Mel-Frequency Cepstral Coefficients(MFCC).Through multi-dimensional noise analysis,the chamber can comprehensively assess the noise characteristics of the tested objects,providing rich data support for R&D personnel.
(3)Self-Supervised Learning Model
Zhongke Shengxuan’s AI-based machine audition system employs a self-supervised learning model that can automatically identify abnormal audio signals using only normal operating data.This approach not only improves detection efficiency but also eliminates the need for a large amount of abnormal data,reducing detection costs.
Zhongke Shengxuan’s Silent Test Chamber,with its ultra-low noise background,wideband free-field acoustic field,and intelligent detection system,provides an ideal testing environment for precise acoustic measurements.Whether in the fields of home appliances,automobiles,or 3C products,the Silent Test Chamber helps enterprises enhance product quality,optimize R&D processes,and strengthen market competitiveness.
