  Acoustic cancellation floor sound insulation cushions are mainly used for KTV, disco, factory, home theater, building slabs, slow rocking bars, hotels, gyms and other ground noise with strong noise sources. The sound cancellation product is particularly suitable for ground acoustic isolation that is connected to a commercial center or entertainment venue.

  Acoustic cancellation sound insulation cushion installation:

  1.) Ensure that the base surface is flat, no sharp objects, no protrusions, and cement mortar should be used for leveling before laying the sound insulation mat.

  2.) Lay the soundproofing mat. If the joint is overlapped or flat, the width of the overlap should not be less than 50mm. For the flat joint, the joint must be glued with special glue. Tape the seam at the seam to cover it.

  (After laying the soundproof mat, it is better to lay a layer of good damping damping felt)

  3.) Fold the edge of the soundproofing pad up at the edge of the wall, 15-20cm in height and stick it to the wall with adhesive points. The seams of the folded parts should also be taped tightly to prevent the formation of rigid joints.

  4.) C20 fine stone concrete with a thickness of not less than 40mm shall not be replaced by cement mortar. The impact sound of the building is mainly caused by the collision between the object and the building member, and the vibration wave propagates along the building structure and flows into the surrounding air. Noise generated by radiation in the air. Floor slabs are the main source of impact noise. Collisions between door and window switches, objects falling on the ground, table and chair dragging, and the heel strikes when people walk on the floor will produce impact noise. Floor impact noise will not only radiate to the room below it, but also connect building components such as walls and columns.

  Because the attenuation of the impact noise in the building structure is very small, the sound can be transmitted very far, especially in the residential buildings, there are many metal pipes connected up and down, which further extends the noise propagation distance, thus causing serious noise pollution. .

  The sound-absorbing sound-absorbing cushion adopts innovative raw materials and production technology to solve the traditional moisture absorption, rot, insects and high cost of floor slab insulation materials such as cork board, sugar cane board, glass wool board and rock wool board. Disadvantages provide a good solution for modern building floor sound insulation systems.

  Acoustic cancellation sound insulation cushion features:

  1.) The sound insulation cushion is made of a medium density polyurethane rubber with a thickness of 5--12 mm. The impact sound has a particularly good sound blocking effect over the entire frequency range, effectively isolating the impact noise and airborne noise.

  2.) This sound insulation mat is a medium-density coil. Its perforation rate and aperture are specially designed to be soundproof, shock-absorbing, waterproof and mildew-proof. It is suitable for all kinds of humid environments.

  3.) Sound insulation cushion is a kind of green and environmental protection, with a service life of more than 50 years. The construction is simple, and it is cut with a utility knife during installation.

  4.) It does not contain formaldehyde, xylene and other organic volatiles harmful to the human body, and it is not irritating to human skin.

  5.) It has good extensibility: it is resistant to aging, impervious to water, and has the functions of waterproofing, moisture proof and heat preservation.

  Sound insulation cushion sound insulation principle:

  1.) Impact sound isolation

  Through the elasticity of the rubber particle insulation mat, the entire floor is formed into a floating structure, and the solid sound transmission effect is cut off. It also improves the anastomosis effect of the upper ground and enhances the acoustic impedance. Through the tiny holes of the nano rubber foam, the sound energy of the sensitive frequency band of the human ear generates cavity resonance, weakens the energy of the sound, and achieves the purpose of isolating the impact sound.

  2.) Air sound isolation

  The air bubble cavity resonance effect is used to change the frequency of sound propagation, reduce the number of reflections, and achieve the purpose of isolating air sound.

  3.) Sound insulation effect:

  Lay the product on the concrete floor and apply a layer of 4cm thick cement. When the area of the sound insulation after tiling is more than 6 square meters, the concrete should be equipped with a reinforced steel mesh. Note that the steel mesh should not pierce the soundproofing mat. The steel mesh must be guaranteed. The upper middle part of the concrete layer.

  4.) According to different ground requirements, lay decorative layers such as floor tiles and floors.
