1. The influence of density on sound insulation performance:
The density of Sound Insulation Sponge is one of the key factors affecting its sound insulation performance. Density refers to the mass of sponge per unit volume, which determines the structure and number of pores inside the sponge. When the density of the sponge is moderate, the size and distribution of its internal pores are more reasonable, which can effectively absorb sound waves and reduce the reflection and propagation of sound. This is because when sound waves pass through the sponge, they collide and rub with the air molecules in the pores, thereby consuming sound energy and reducing the intensity of the sound. Therefore, a sound insulation sponge with moderate density can provide better sound insulation.
2. Ideal density range:
For Sound Insulation Sponge, there is an ideal density range that can achieve the best sound insulation performance. This range may vary depending on different materials, different manufacturing processes and different application scenarios. Within this ideal density range, the internal pore structure of the sponge is neither too loose nor too tight, which can maximize the absorption of sound waves and reduce the transmission of sound. In order to determine the optimal density range, manufacturers usually conduct a lot of experiments and tests to ensure that the sound insulation performance of the product meets market demand.
3. Considerations in practical applications:
In practical applications, many factors need to be considered when choosing Sound Insulation Sponge. In addition to density, factors such as the use environment, noise type, and sound insulation requirements need to be considered. For example, in occasions where noise propagation needs to be strictly controlled (such as recording studios, cinemas, etc.), you may need to choose sponges with higher density and better sound insulation performance. In some occasions where sound insulation requirements are not high (such as home theaters, offices, etc.), you can choose products with moderate density and higher cost performance. In addition, other indicators such as the fire resistance and environmental protection performance of the sponge need to be paid attention to to ensure its safety and reliability in practical applications.
4. Reference numbers and information:
Although the specific numbers may vary depending on different products and different test conditions, in general, within the ideal density range, the sound insulation effect of Sound Insulation Sponge can reach a good level. For example, some high-quality sound insulation sponges can show a sound insulation effect of more than 30 decibels in laboratory tests. This means that in appropriate application scenarios, these sponges can significantly reduce noise levels and provide a quieter and more comfortable environment. However, it should be noted that these numbers are for reference only, and the actual effect may vary depending on the specific situation.

Protect the main structure of the building and prolong the life of the building. Since the external thermal insulation is placed the thermal insulation layer on the outside of the structure, the stress caused by the structural deformation caused by the temperature change is reduced, and the erosion of the structure by harmful substances in the air and ultraviolet rays is reduced. Effectively eliminate “thermal bridge” In the past, internal insulation was used, and “thermal bridge” was unavoidable, while external wall insulation effectively prevented the generation of thermal bridge and avoided condensation.
