Description

Eco-friendly interlayer noise prevention structure {ECO-FRIENDLY INTERLAYER NOISE PREVENTION STRUCTURE}

The present invention relates to an interlayer noise structure, and more particularly, to an eco-friendly interlayer noise prevention structure using natural fibers.

These floor noises are collectively called floor impact sounds, piano sounds, audio sounds, conversation sounds, TV sounds, etc. Among the floor noises, floor impact sounds are classified into lightweight shock sounds (58㏈ or less) and heavy shock sounds (50㏈ or more). .

In particular, among the floor noise, the floor impact sound (solid transfer sound) generated by the direct impact on the concrete surface has a property that is easily transmitted to adjacent generations.

These noises are mainly the sounds of children running upstairs and downstairs, as well as dragging and dropping objects.

Floor noise, like other noise pollution, has a negative effect on mental and physical health, and as apartments such as apartments have become common, social problems such as many problems and complaints among neighbors have begun to emerge.

However, in order to reduce such inter-floor noise, various types of inter-floor noise materials have been developed, but it is difficult to effectively remove vibration and noise generated between inter-floor structures.
