Soundproofing board is a type of panel that acts on the sound insulation effect. There are classifications for building sound insulation and structural sound insulation.
Not all frequencies of sound can be blocked by soundproofing boards. Objects have inherent resonance frequencies, and the soundproofing effect of soundproofing boards decreases when the sound is close to the resonance frequency of the object.
Soundproofing boards have the difference between isolating airborne sound and vibration sound. Air green soundproof boards are boards that clearly isolate the sound that propagates in the air. Vibration sound insulation board refers to the board and system that separates the sound propagated in rigid components such as reinforced concrete monolithic houses.
