Product Introduction

 

Metal sound absorption/insulation board is generally composed of steel plate on sound insulation surface layer, damping layer, sound absorption layer, waterproof and breathable layer and steel pore plate. 


Based on project needs, steel plate on sound insulation surface layer can adopt flat type and corrugated type, adapt to several surface treatment processes, e.g. painting and powder spraying, and utilize thermal transfer printing technology. The surface can be made from several apparent materials.

Round pore plate and rainproof pore plate are generally adopted. Round pore plate is usually used indoors, e.g. sound absorption/insulation board on the walls and roof of noise reduction room, sound absorption/insulation board on the walls of noise reduction hood, etc.; rainproof pore plate is usually used outdoors, e.g. highway, metro and industrial factory boundary sound barriers, etc.

Laboratory

As the key environmental protection laboratory in Sichuan Province, our acoustical laboratory covers 521 square meters, and is composed of reverberation chamber, sound insulation chamber, silencer dynamic evaluation laboratory and impedance tube laboratory. The laboratory now is the largest noise control technology and acoustic material research & test center in southwestern China, and leads domestic noise control field. Silencer dynamic evaluation laboratory  
now is the largest silencer test platform in China.  
Our laboratory is designed by architectural acoustics design team from Tsinghua University based on relevant national standards and by reference to well known acoustical laboratories at home and abroad. Main measurement instruments are manufactured by B&K, Denmark (a measurement instrument manufacturer ranking No.1 in the world, and providing noise and vibration solutions). The laboratory conforms to the testing conditions of CMA (China Metrology Accreditation), and has issued the reports conforming to CMA requirements for customers, and especially plays an irreplaceable role in the development of new productions and the detection of product quality. 
Laboratory has established a resource sharing and advantage complement relationship with several institutions, e.g. Architectural Physics Laboratory of Tsinghua University andAcoustics Institute of National Institute of Measurement and Testing Technology, etc., and does business with them in product R&D, performance detection and other fields.  
Objectives of our laboratory are to correctly evaluate the sound absorption, sound insulation or sound elimination property of each kind of noise reduction product or structure with various measurement methods, support the design and optimization of noise reduction scheme, and ensure the noise of noise reduction engineering really meets the standard!
