Type A Sound Reduction Wall Panel
Type A Sound Reduction Wall Panel is a type of panel that acts as a soundproofing effect. There are building sound insulation and structure sound insulation classification. Acoustic panels are not all frequencies of sound can be blocked, the object has an inherent resonance frequency, close to the resonance frequency of the object of the sound, sound insulation panels sound insulation effect is significantly reduced. Sound insulation panels have the difference between airborne sound and vibration sound. Air sound insulation panels, that is, the barrier is in the air propagation of sound panels.
Overview
Design:
Another kind of propagation of sound is cross-media propagation. That is, from a medium, through the critical contact surface of the two media into another medium, at this time, the transfer of sound energy is essentially the transfer of vibration amplitude.
Cross-media propagation, the greater the difference between the density of the two media, the greater the loss of sound energy.
In practice, the air for human activities under normal space, so the greater the difference in density with the air material is generally very high density materials (much lower than the density of air in addition to the vacuum, but also really not much material), can be regarded as soundproofing materials.
The higher the density, the better the sound insulation. Such a material made of panels, called soundproof panels.
