Application
Precision Anechoic Chamber Construction: As the core sound-absorbing structure in an anechoic chamber, metallic anechoic wedges efficiently absorb sound wave energy, eliminating reflections and echoes to provide a pure, interference-free acoustic environment for analyzing acoustic materials and studying sound propagation patterns. This ensures high accuracy of experimental data.
Electroacoustic Product Testing: In parameter testing for electroacoustic products such as microphones and loudspeakers, metallic anechoic wedges effectively reduce ambient noise and sound wave reflections, enabling precise capture of the products' electroacoustic characteristics and guaranteeing the reliability of test results.
Industrial Noise Measurement: For noise testing of machinery, household appliances, and other products, metallic anechoic wedges optimize the testing environment, minimizing external interference to accurately measure noise levels during product operation. This supports data-driven noise control and product optimization.
Progressive Impedance Matching Structure
Gradual wedge design from tip to base creates gradient acoustic impedance, maximizing sound absorption through multiple reflections while optimizing space efficiency for pure acoustic environments.
Metal-Frame Durability
Robust metal framework ensures industrial-grade impact/corrosion resistance, maintaining stable performance in harsh, high-intensity settings and extending product lifespan.
Customizable Solutions
Tailorable materials, dimensions, and structures adapt to diverse applications, offering precision-tuned acoustic solutions.
Flexible Installation and Space Optimization
Modular design supports versatile mounting in complex spaces, combining effective sound control with space-saving efficiency for streamlined installations.
As shown in the image, this product is exclusively tailored for customers, with customizable adjustments in size, material, and design to precisely match your spatial design needs.

Laboratory testing
NCC Acoustic Laboratory - A Laboratory Professionaly Committed to Serving Customers
We exert every ounce of our strength to construct a high-end, avant-garde laboratory endowed with autonomous control capabilities. For all bespoke products, be it in terms of specifications, dimensions, or acoustic requisites, prior to entering the mass production phase, we shall enforce rigorous and meticulous pre-production sample testing procedures. Only upon thorough confirmation that all indicators are up to par will we invest a considerable amount of human and material resources to embark on mass production endeavors, thereby effectively guaranteeing that each and every batch of large-scale goods delivered to clients possesses outstanding quality.
The fabricated product samples are positioned within the spacious window of the laboratory and securely fastened through professional sealing measures. Through precise adjustment of the relevant parameters and concurrent utilization of advanced and precise apparatuses for comprehensive and profound testing, it is ultimately ensured that the products can fully comply with the exacting requirements of customers.
As depicted in the illustration, the external noise of the laboratory attains 80.1 dB, while through random measurement, the internal acoustic laboratory drops to 36.4 dB or even lower. The elevated standard of sound insulation not only ensures the accuracy of the experimentation but also furnishes a robust guarantee for the test outcomes.
