In practice, soft and porous materials such as glass wool, rock wool and polyurethane are primarily used in soundproof designs.
Despite their excellent sound absorption properties, soft and porous materials have some shortcomings such as the loss of soundproof properties with the breakdown and dispersion of the material, vulnerability to fire and contamination of the environments.
When a sound wave enters the surface of foam, the air between pores begins to vibrate as well as cell wall materials.
A material with a lower density has a relatively wider cell wall surface 10mm area inside, and because of this, the air between pores began to vibrate and the cell wall materials began to materials when sound wave entered the surface of foam.

With the rapid economic development, urbanization leads to many problems, including a general rising price of material elements, resource depletion and environmental pollution.
However, the economic development theory indicates that resource-environmental factor takes a role in the production function only when industrial sector produces on basis of material factors.

Wang Kaiyun (2007) imposed restriction on the scale of the ecological carrying capacity , it was thought that the ecological carrying capacity refered to that regional ecological system can bearing population scale and its corresponding economic mode in the condition that ensured the rational development and utilization of the resources and the ecological environment benign circulation and certain material exchange scale in different scale area and in a certain period of time.

The assessment of sweet sorghum straw bio-feed fermentated by the Compound Microbial Agent in bags and cellar pits Shuyang Wang1,3a,GuoqingXiao1,WenjiangLi1,JihongChen1, Jian-ping Liang1,Jing Liu1,Xiangyang Zhang2,Hong Su2, Bailing Jiang1 1 Department of biology Physics, Institute ofModern Physics,Chinese Academy of Sciences, Lan zhou 730000, China; 2Gansu Agricultural University, Lanzhou 730070, China; 3Lanzhou University, Lanzhou 730070, China; a wangsy@impcas.ac.cn Keywords: Compound Microbial Agent; sweet sorghum straw; ferment; Assessment; Evaluation of milk ; Abstract: The results indicated that the sweet sorghum straw bio-feed fermented in bags and cellar pits by the Compound Microbial Agent both could increase the content of the crude protein(CP)and reduce the content of the fibrinogen(FIB) compared with control group.
In addition, the straw of sweet sorghum is an abundant and low-cost lingo cellulosic material that can be synthetically used as a raw material for ethanol production with some by product with high additional value. [2] The experiment is aimed at evaluating the sweet sorghum straw bio-feed fermented by the Compound Microbial Agent in bags and cellar pits prepared by the Chinese Academy of Sciences Institute of Modern Physics, and assessing the milk quality after feeding the cows with it.
