Description

[0001] The present invention relates to an intelligent interlayer noise reduction system,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intelligent interlayer noise reduction system, and more particularly, to a system for mitigating interlayer noise by generating an inverse noise corresponding to a noise generated in an upper slab.

There is a lot of controversy due to the vibration and noise generated in the upstairs, the downstairs, or the next house in the apartment where the family of several households, such as the villa or the apartment, resides in each divided space.

In order to minimize such floor noise and noise of the neighboring house, a method of inserting expensive interior material at the time of building construction or installing a soundproof wall separately in case of building completed is used to minimize disputes among neighbors.

However, these methods have a high cost for the construction or maintenance of the building due to the high cost of the interior material or the soundproof wall itself. However, after installing the interior material or the soundproof wall, There is still no separate configuration to recognize and there is still the possibility of frequent disputes between neighbors.

 In addition, an interior material or soundproof wall is installed based on a predetermined noise level, but there is also a limit in which it is impossible to take appropriate measures when vibration or noise of an unexpected size occurs at the time of installing the interior material or the soundproof wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. And this does not mean that the spirit and scope of the present invention are limited.

And a controller 30 for analyzing a signal of the vibration sensor 10 to generate an inverse noise according to a noise generated in the slab S.

The intelligent interlayer noise damping system 100 of the present embodiment analyzes the vibration transmitted to the slab S and predicts the generated noise pattern and generates the inverse noise corresponding to this noise by the speaker device 20 It cancels the noise.

The vibration detection sensor 10 is coupled to the lower portion of the slab S. When the child leans at the upper portion of the slab S, it is transmitted to the vibration detection sensor 10 by vibration. There is noise generated according to the pattern and intensity of vibration.

The control unit 30 stores noise data corresponding to the vibration signal transmitted from the vibration sensor 10 and data on the inverse noise to be generated in order to cancel the noise. Accordingly, the control unit 30 generates the inverse noise through the speaker device 20 to the outside. Thus, the noise is alleviated.

On the other hand, a feedback microphone 40 may be further coupled to detect whether the noise is well canceled. If the noise is well mitigated even though the inverse noise is generated in the speaker device 20, the pattern of the inverse noise corresponding to the noise is not suitable. The control unit 30 determines whether or not the inverse noise is appropriate based on the information of the feedback microphone 40. [ If the inverse noise is not a proper pattern, a new type of reverse noise is generated through the speaker device 20 when the same noise is generated in the future. In this way, the control unit 30 accumulates inverse noise data suitable for a specific noise, and then generates a corresponding inverse noise when the specific noise is generated.

The speaker device 20 may be a woofer speaker or a film-type speaker.
