Product Description

 

Product Description

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.

 

Design Advantage

• 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. 


We are also able to offer a full range of engineered solutions to industrial noise, all centredaround modular components that can work independently or as part of a package to solve even the most complicated of projects.


In addition to the acoustic wedge, we can also provide a number of other auxiliary solutions to control noise, including:

• HVAC attenuators
• Standalone acoustic doors and windows
• Acoustic louvres
• Splitter silencers
• Hot gas exhausts including emission control
• Vent silencers
• Generator set enclosures, including containerised solutions
• Gas turbine acoustic packages
• Power generation filtration
• Anti-vibration mounts
• Tuning panels, reverberation control and absorption systems
• Acoustic monitoring and analysis
• Aero-engine testing facilities
• Acoustic testing facilities, including anechoic and reverberation chambers

 

Testing Report

Testing Report

All Reports can meet the American Standars, the sound testing we did with Intertek

 

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.

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. 

 

Packaging & Shipping

All our packing with Rubber clip board,don't need to do fumigation.
