Our Advantages

Accurate noise reduction across all frequency bands.

    Through unique acoustic structural innovation, it is possible to target the handling of low-frequency traffic roars and high-frequency industrial equipment noise, achieving effective control of all frequency band noise from low to high, and solving the problem of multi scene noise.
 

Dual advantages of lightweight and durability.

    Using high-strength materials such as aluminum alloy and galvanized steel to create panels, while maintaining lightweight characteristics, it has excellent impact resistance and weather resistance, can adapt to complex and harsh environments, reduce maintenance investment in the later stage, and extend the product's service life.

Modular and efficient construction.

    All components are standardized prefabricated in the factory, and there is no need for complex processing on site. Installation can be completed by simple splicing and assembly, greatly reducing construction time and improving project landing efficiency.

Customized adaptation design.

    The color, size, and structural details of the panel can be customized according to actual needs, which not only allows the noise reduction product to naturally blend with the surrounding environment, improving overall aesthetics, but also flexibly adjusts the noise reduction effect to meet the needs of different scenarios.

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.
