Sound Insulation Board
Sound insulation board is a kind of plate that acts on sound insulation effect. There are classification of building sound insulation and structure sound insulation. Not all frequencies of sound can be blocked by sound insulation boards. Objects have natural resonance frequencies. Sound close to the resonance frequency of objects can significantly reduce the sound insulation effect of sound insulation boards.

Sound Insulation Board
Sound insulation board is a kind of plate that acts on sound insulation effect. There are classification of building sound insulation and structure sound insulation. Not all frequencies of sound can be blocked by sound insulation boards. Objects have natural resonance frequencies. Sound close to the resonance frequency of objects can significantly reduce the sound insulation effect of sound insulation boards.
General objects have sound insulation effect, but we call the panel whose average sound insulation (an infinite piece of material is placed between the sound source and the measured point in an infinite space) exceeds 30dB as the sound insulation panel. Sound insulation boards are generally low-density materials.
The sound insulation board has the difference between air insulation sound and vibration sound. Airborne sound insulation board, that is, the board that blocks the sound transmitted in the air. Vibration sound insulation board refers to the board and system that block the sound transmitted in rigid members (such as reinforced concrete monolithic buildings).
According to the classification of civil engineering, it can be divided into building sound insulation and structure sound insulation.
