No soundproofing in a house is a very difficult, torturous and painful feeling. When you want to rest, you can hear all the sounds that other people make, which affects the quality of your sleep, and when you want to be quiet, the sounds that other people make make you feel very irritated and depressed.

Acoustic insulation materialsAcoustic insulation materials are materials that attenuate or isolate the transmission of sound waves. Sound insulation performance is good or bad with the material of the incident sound energy and through the sound energy difference in decibels, the larger the difference, the better the sound insulation performance.
For a building space, its enclosure structure by the role of the external sound field or directly affected by the impact of the object vibration, it will radiate sound energy to the building space, so the sound outside the space through the enclosure structure to the building space, which is called the "sound". Passed in the sound energy is always more or less less than the external sound or impact energy, so that the enclosure structure isolates a part of the role of its sound energy, which is called "sound insulation". Sound transmission and sound insulation is just a phenomenon from two different perspectives, a pair of opposite concepts.
