Description
Technical field
The present invention relates to pugging fields, and in particular to a kind of pugging.
Background technology
With the improvement of living standards, people increasingly pay attention to the sound insulation property of building.The sound insulation property of building is divided into
Air-borne sound oise insulation factor and strike note oise insulation factor, the decaying very little of the energy of solid sound in traditional building material, spread speed ratio
Faster, propagation distance is again farther for air.The air-borne sound soundproof effect of continuous thick and heavy and hard concrete floor is good, but for
The effect of strike note is poor.Therefore the resident family for staying in lower layer generally can't hear voice upstairs, but can obviously experience upper layer and live
Family drags tables and chairs, child runs jump and the sound on heel contact ground.Under the trend that especially present operating pressure incrementally increases,
Small sound can further influence the state of the suspend mode of resident family.
