Sound insulation principle: through the elasticity of nano foam, the sound insulation pad on the ground can form a floating structure on the whole ground, cutting off the solid sound transmission effect. It also improves the coincidence effect of the upper ground and enhances the acoustic resistance. Through the tiny holes of the nano foam, the acoustic energy in the sensitive frequency band of the human ear can generate cavity resonance, weaken the energy of the sound, and reduce the noise. The ground sound insulation pad can also change the frequency of sound propagation and reduce the number of reflections through the resonance effect of the nano foam cavity to achieve the purpose of isolating the impact sound.

    Installation method of floor acoustic pad：

    1、The ground shall be leveled and cleaned first. Before installation, the floor sound insulation pad shall be cut according to the required size.
    2、Lay the sound insulation pad on the ground, seal the joint with glue at the joint, and then stick a layer of sealing tape at the joint to cover it to prevent the sound from passing through the solid on the ground.
    3、During construction, air bubbles shall be avoided between the ground sound insulation pad and the ground.

    4、After the product is paved, cement and ceramic tiles shall be paved immediately.
