The principle of gradual transition is applied to make porous (or fibrous) materials into conical or wedge-shaped sound absorbing bodies. When sound waves are incident from the tip, due to the gradual transition property of the sound absorbing layer, the sound resistance of the material can match well, allowing the sound waves transmitted to the sound absorbing body to be effectively absorbed.

• 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.
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.
All Reports can meet the American Standards, the sound testing we did with Intertek
NCC acoustic equipment includes a variety of fields, structural sound insulation equipment, while shielding the environment from unnecessary noise according to user requirements.
Our louvres are available in an array of standard modular sizes, meaning that a wide range of performance requirements can be met. By using our range of acoustic louvres, it overcomes architectural consistency issues, especially where space is limited.
