Sound-absorbing and sound-insulating treatment in the acoustic decoration of home theaters. Generally, the listening room is connected to the main room, which not only increases the usable area of the house, but also is very convenient for entering and exiting the audio-visual room. In most cases, if you DIY a Audition rooms are generally "brick and tile houses". The interior walls should be filled with sufficient fireproof and sound-absorbing materials in advance to reduce the pressure on the walls and reduce the frequency of resonance.

Damping sound insulation board (acoustic shield sound insulation board) is a kind of high-performance polymer viscoelastic damping sound insulation coating and constrained damping layer, which together constitute a constrained damping structural plate (viscoelastic damping structure). When vibration is excited, the viscoelastic damping coating can effectively convert the vibration energy into heat energy, thereby playing an efficient sound insulation effect.

The diffuse sound-absorbing body QRD is composed of a series of checkerboard "caissons" of different depths. Each grid has a different depth and reflects sound waves of different frequencies. The reflection of the two-dimensional QRD diffuser is an omnidirectional three-dimensional reflection.

Note for sound absorption and sound insulation in home theater acoustic decoration To sum up, in the sound insulation decoration of entertainment venues, the selection of materials is very important. A good sound insulation board can ensure a good sound insulation effect. It is recommended that the majority of friends can choose the above when designing home theater decoration The environmentally friendly green sound-absorbing panels have good sound insulation and noise reduction effects,thus bringing a good atmosphere to the indoor environment.
