Product Description

Product Description

 

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.

NCC Boheng Fabric Splitting, using fire-resistant cloth to wrap the splitting bracket, filled with soundproof cotton inside, can absorb medium to high sound frequencies.The internal filling materials of the fabric cutting edge include yellow standard cotton, white formaldehyde free glass cotton, environmentally friendly fiber cotton, etc; It is more widely used in various laboratories, with a service life of about 30 years. When the service life is reached, it can be purchased separately at a lower cost, and its sound reception effect has greater advantages compared to other acoustic product

 

Sound absorbing cotton filling

The interior is filled with sound absorption and insulation material, and adopts reasonable structure to absorb sound waves.

 

Fabric wedge

The use of fireproof cloth, noise suppression and fire prevention, and moderate weight, easy to install on the wall and ceiling.

Metal wedge

Usually used galvanized steel plate and aluminum alloy plate, and the use of non-woven cloth wrapped sound-absorbing cotton, dirty and durable, long service life.

Wedge mounting structure 

Sound wedge generally has a certain thickness of the base, easy to install, and easy to achieve the best sound absorption effect, generally sound wedge and the wall will leave some gaps, forming a cavity, will make the cutoff frequency is lower.

 

Staggered arrangement 

Increase the absorption area of sound waves, so that the sound waves incident on it are almost completely absorbed without reflection, and the main use is to build a full anechoic chamber and a semi-anechoic chamber.

 

Product Range

 

• Construction of sound absorption structure necessary for precision anechoic chamber.

• Used to test the electroacoustic parameters of electroacoustic products.

• All kinds of machinery, mechanical and electrical, light industry, household appliances and other products noise measurement.

• Scientific experiments on speech acoustics, music acoustics, psychoacoustics, and sound propagation.

• A wide band of high efficiency sound absorption characteristics including low frequencies is obtained, and the cutoff frequency of anechoic chamber can generally reach 60-70 Hz.

• The specific specifications of the acoustic wedge are determined by the cut-off frequency to be 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. 
 

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.
