Product Description

Product Description

NCC Anechoic wedge can absorb sound waves of different frequencies, maintaining a stable sound absorption effect from low frequencies to high frequencies. Moreover, it can be hung on the roof or installed on the wall according to actual needs. The installation methods are flexible and diverse, capable of adapting to different spatial layouts and building structures.

NCC Wedge Absorption--are mainly used in fully anechoic and semi anechoic laboratories.

Type	Metal Acoustic Wedge	Cloth Acoustic Wedge
Different	Using metal materials as outer packaging materials requires bending and polishing during the manufacturing process, followed by the application of paint baking technology. Metal wedges have better durability and a longer service life, but are about four times more expensive than fabric wedges.	Just need to make a fabric cover and fill the materials inside it. Fabric wedges are widely used in major laboratories, with a service life of about 30 years and relatively low cost.
Same	The internal filling materials are all the same, including yellow standard fiberglass wool, white formaldehyde-free fiberglass wool, and eco-friendly fibers.

Application Scenarios Professional acoustic spaces: recording studio, mixing room, broadcasting studio, live broadcast room, cinema, home theater, music hall, piano practice room.

Industrial and commercial noise reduction spaces: reduce the impact of mechanical noise and environmental noise on personnel or equipment. Such as industrial workshops, equipment rooms, conference rooms, lecture halls, and open plan offices.

Special functional spaces: recording studio control room, soundproof testing room, anechoic room, KTV, Bar (local area).

Our Advantages NCC acoustic equipment includes a variety of fields, structural sound insulation equipment, while shielding the environment from unnecessary noise according to user requirements. The sound absorption efficiency is extremely high, especially adept at solving the "low-frequency sound absorption problem".

Broadband sound absorption coverage, suitable for acoustic needs in multiple scenarios.

Strong structural stability and reliable long-term performance. In scenarios that require extremely low background noise and non reflective sound fields (such as acoustic testing and precision instrument calibration), acoustic wedges are the core solution.

No need for complex multi material splicing.

• Sound absorbing wedge is a kind of special sound absorbing structural material for strong sound absorbing field, the use of porous (or fibrous) material molding cutting, made into a cone or wedge sound absorber, firm without deformation.• Sound absorption wedge is suitable for strong airflow environment, the main object is high-quality anechoic chamber, the absorption of low frequency is more effective, can eliminate standing waves, to eliminate the requirements of echo, low cut-off frequency sound absorption coefficient greater than 0.99.• The sound insulation wall of the anechoic chamber is installed with an anechoic wedge, which can form a smooth layer connection, so that the uncertainty and irregularity of noise acoustic wave reflection can be extended, and the sound absorption performance of the anechoic chamber can be improved.• Compared with ordinary acoustic wedge, the V-shaped and W-shaped acoustic wedge made of polyester has the characteristics of smaller occupancy volume and more reasonable price.
For each individual project, it is possible to select a panel design which has the required sound transmission loss and sound absorption ratings. Laboratory TestingNCC 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.
