Technical Field

The invention relates to the technical field of sound insulation floors, in particular to a ground mat and a floor.

Background

Noise in buildings is classified into air sound and impact sound according to the manner of generation and the characteristics of propagation. The air sound is the vibration of the surrounding air particles caused by the vibration of the sound source and is spread outwards in the form of longitudinal waves at intervals. For example, the sound heard by a person when the person is walking is airborne sound. Impact sound is noise generated by vibration energy directly transmitted to a building structure due to direct contact of a vibrating body of a sound source with the building structure or impact between solids. Such as people walking and furniture moving, the noise heard under the floor is the impact sound.

Before being laid on the ground, the floor needs to be laid with a layer of floor mat of a certain thickness, which is usually made of foamed material. The ground mat can achieve the effects of moisture prevention, mildew prevention, foot feeling improvement and the like. The conventional floor mat is generally designed to improve the feeling of the feet, and the sound is uniformly transmitted downward after penetrating through the floor mat, so that the conventional floor mat has a poor blocking effect on the hitting sound. And the traditional ground mat is provided with regular patterns or shapes after being processed by the roller, so that the requirements of attractive appearance and uniform foot feel are met. Some shapes have a certain sound insulation function objectively, but are not specially designed for sound insulation, and the sound insulation effect is poor.
