At present, Australia speeding "brand insulation board, has won the recognition of the high-end consumer level home and abroad," Australia speeding "brand noise barriers to adhering to the concept of the production of acoustic engineering principles and landscaping concept, continuous efforts to improve the sound insulation materials, professional level. Australia speeding not only provide first-class panels, fully reflects the respect and care for humanity. 
 Generally, when to buy insulation board should pay attention to the following matters. 
 Wall of noise goals 

 Whether the new noise walls, the old wall noise transformation, we need a more clear sound insulation requirements, the amount of wall insulation needed to achieve the number of decibels, and then select the economy, the noise wall sound insulation target board and develop wall soundproofed program. 
 Enacted in 1988 "GB/J-118 civil construction and sound insulation design standards under the general standard of ordinary civil wall insulation is 45 db, but this standard is developed twenty years ago. With the home theater, the popularity of household appliances and domestic cars, as well as the ubiquitous production, life and commercial noise, leading to modern man facing the noise pollution intensity has been more serious. Architecture, Tsinghua University Institute of Acoustics, after market research found that the wall insulation in the 45 db, at least 50% of the people is not satisfied; If the wall sound insulation to 50 dB, probably less than 10% of people is not satisfied. Therefore, the general sound insulation wall, acoustic targets can be set at about 50 db; course, special places, such as studio, studio, high-end KTV such as walls, wall sound insulation may be required to achieve 60 db or or more. 
 However, in China, wall sound insulation, lack of knowledge, do not know to pass laws to protect their own interests (noise wall is not up to, can sue the developer), together with developers based on lower costs, leading to China's existing ordinary commercial residential wall noise generally only about 40 db, can hardly satisfy the sound insulation requirements. In this case, if the transformation of Wall Sound Insulation, it is recommended to improve the sound insulation value to more than 50 db. Of course the ultimate wall insulation value of the number of decibels, but also depends on the sensitivity of the noise, as well as the practical use of space to be the transformation. If the user is very sensitive to noise, wall of sound reduction target can be increased to more than 55 db or higher; or if you transform the space is very high sound insulation requirements (such as home theater, bedroom or conference room, etc.), wall sound insulation can be further improved.
