Product Description
The anechoic wedge operates based on the principle of gradual transition, shaping porous or fibrous materials into wedge-shaped structures. This design allows the acoustic impedance of the material to gradually match the impedance of the surrounding air as sound waves propagate from the wedge's tip inward. Not only does this design enhance noise reduction efficiency, but it also optimizes space utilization, making it the preferred choice for applications requiring precise acoustic control.

Application
Acoustic laboratory: Through the anechoic wedge's efficient sound wave absorption, environmental noise interference is reduced, providing a pure acoustic environment for precisely measuring acoustic materials and studying sound propagation characteristics, ensuring the accuracy of experimental data.
Anechoic chamber: In a full anechoic chamber, the anechoic wedge enhances sound wave absorption during the testing and calibration of electro-acoustic equipment, avoiding reflection interference. In a semi-anechoic chamber, it optimizes the product noise radiation test environment, enabling more precise capture of product noise characteristics.
Recording studio: The anechoic wedge absorbs environmental noise, echoes, and reverberation, creating a low-reflection acoustic space to ensure pure sound during music recording and elevate audio recording quality.
Wide frequency adaptability:
With good frequency adaptability, it can absorb sound waves of different frequencies, covering the acoustic demands of various scenarios.
Optimized structural design:
Features excellent impedance matching. The structure gradually increases from the wedge tip to the base, enabling multiple sound absorptions and enhancing sound absorption efficiency.
Extensive scene adaptability:
As a necessary material for professional acoustic venues, it meets the sound absorption requirements of different scenarios like recording studios and anechoic chambers.
Strong installation flexibility:
Supports flexible installation methods, adapts to various complex spatial environments, and improves the convenience of practical applications.

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.
