 Learn more about the noise barriers and sound insulation materials similarities and differences 
 The so-called sound insulation is able to sound or noise and vibration sound, isolated, cut off, the separation of material, which we call sound insulation materials, sound insulation plate is made of insulation materials, insulation boards. Affect the normal life because of people's lives in many places have some degree of noise, and therefore must have a sound insulation material to maintain the people's normal life. 

 The principle of the noise insulation materials, noise volume to follow the principle of mass law, sound insulation materials unit of the greater density of the dense surface, the noise the greater the amount of surface density and the noise is proportional to the amount of relationship. Insulation materials have a certain flexibility in the physical, when the acoustic wave incident will stimulate the vibration propagation in the compartment. When an acoustic wave is not perpendicular to the incident, but the compartment was an angle θ incident sound wave-front in order to reach the compartment surface, while the horizontal transmission of the first compartment of the acoustic excitation compartment bending vibration wave along the compartment, if the bending wave propagation velocity consistent with the moving speed of sound in the air gradually to reach the compartment surface, sound waves will strengthen the bending wave vibration, a phenomenon known as a consistent effect. Particularly large when the bending wave vibration amplitude to the other side of the air radiated acoustic energy is particularly large, thereby reducing the acoustic effects. 

 Insulation materials have a variety of general common: building insulation materials, the KTV insulation materials, decoration, insulation materials, noise damping materials, shock absorption and vibration reduction materials, sound-absorbing decorative materials, decorative sound-absorbing cotton panels, noise barriers, sound insulation and fireproofing material and so on. Common Specification Thickness: 2.0mm insulation materials, 4.0mm type, insulation materials, 1.2 insulation materials. 

 Sound insulation or noise barriers in the building materials market, a wide variety of everyday people of the more common solid brick block, reinforced concrete walls, wood-block, gypsum board, iron, sound insulation, carpet, fiberboard, and so on. Strict sense, almost all materials have a noise effect, the difference between interval volume of different materials of different sizes. The same material, due to the different surface density, the noise amount is relatively large changes. 



 -------------------------------------------------- ------------------------------------- Our main business scope include: 
 A sound-absorbing material, sound insulation material sales. 
 Second, following the noise reduction project, including noise barriers installed, stadiums, theaters, multi-purpose hall, KTV rooms, disco, bar, central air conditioning, outdoor refrigerator, fans, transformer room, boiler room, elevator shafts, elevator equipment, pumping stations, shopping malls, piano room, karaoke, Voice Department, conference rooms, recording studios, hotels, etc., as well as the device layer (between) the noise is relatively large spaces factory, highway sound barriers, family soundproof walls, floors, ceiling , soundproof door. 
 Australia speeding is a professional noise control Environmental Protection Technology Co., Ltd., successfully resolving a variety of workplace noise problem, the company has a lot of success stories, acoustical experts due to appropriate, tailored for you to create a dedicated noise engineered, allowing you to enjoy VIP services.
