Interior decoration has become an independent industry, large and small companies have mushroomed decoration decoration, all over everywhere. A lot of decoration company to a new style, new materials, new techniques to bring a new look interior architecture decoration, reached a new level. 

 In many cases, the interior decoration has some acoustic requirements. Is not only the various theaters, sports venues and dance halls as well as on studio acoustics, studio and other professional acoustic space itself has a certain technical indicators, and all public places, generally requires communication language or music, even household Housing now also need to have a good music appreciation environment. So must pay attention to the acoustic interior decoration requirements. If we ignore this point, most likely adverse consequences. For example, a water recreation ground, the ground is basically water, over is a big glass dome entry, the absence of acoustic design, resulting in a particularly long hall reverberation time, even when there are cultural performances announcer's words are inaudible. If the corridor or lobby again, doing magnificent, splendid, but even ordinary conversation was, or background music, but also not bad space for a long time passed, the formation of annoying interference noise. 

 Mainly caused by poor sound quality is not a scientific acoustic design. Decoration Engineering Company does not have many qualified acoustic design; some one began to invite experts to do the acoustic design, thinks the future with the "experience", he boldly contracted to design; some East West hit copy, found that other people's secrets, you do soft bag, I have not got software package, you use the perforated plate, perforated plate and I do, in fact, did not grasp the true acoustic requirements; does not rule out some acoustic engineering and technical personnel to understand some knowledge, but room acoustics are not good at the theory and practice, and failed to make the acoustic decoration. 

 Interior design is a system of acoustic disciplines, covers a wider, this article only related to the absorption and interior decoration and sound insulation materials and structural knowledge to make a brief introduction, I hope decoration and owners of acoustic materials and structure understand, can understand
