[0001] The present invention relates to an interlayer noise reduction device using a simultaneous generated offset vibration noise,

The present invention relates to an interlayer noise reducing device configured to mutually cancel a vibrating sound received from a vibration sensor and a vibration sensor generated in a reverse direction against an interlayer noise vibration sound generated in a dwelling house.

The wave motion is called the longitudinal wave and the particle motion is the wave motion. <Wave Propagation Diagram> shows the vibration of the drum. When you hit the drum, the vibrating leather surface moves back and forth in the same direction as the sound progresses, as shown by the arrow in the figure. This type of wave is called a sect. In order to provide a facility for eliminating the interlayer noise by constituting the longitudinal wave to generate a reverse vibration sound to generate interlayer noise in the ceiling slab of the apartment house, and to cancel each other.

Figure pat00001

<Wave Propagation Diagram of the North>

A real-time interlayer noise canceling system (Application No. 10-2013-011111) similar to the present invention includes a sound analyzer for analyzing a sound received from a ceiling through a sound input unit to generate waveform data, A main server having a first peak and a first peak of one or more previously stored reference waveform data to detect coincidence reference waveform data, a main server having offset waveform data corresponding to the reference waveform data detected by the sound detection unit, Wherein the main server generates the waveform data by the inverse phase amplitude of the reference waveform data if the waveform data does not coincide with the reference waveform data stored in the main DB, And the stored reference waveform data is transformed to the antiphase dynamic amplitude, Data generator for generating; real-time inter-layer removal of noise, characterized in that it comprises a system and outputs through the sound generating a canceling waveform corresponding to the reference waveform data and provides a real-time inter-layer noise-canceling system for removing the inter-layer noise.

Figure pat00002

<Representative diagram of real-time interlayer noise reduction system>

The above-mentioned &quot; real-time interlayer noise elimination system &quot; is similar to that of the patent in that the interlayer noise is canceled by generating a sound in the opposite phase, but when the sound is reproduced in the sound generator by analyzing / The sound is input to the sound input unit again to generate an infinite loop (howling). If there is a slight time difference between the inter-layer generated sound and the reproduced sound, the sound can not be canceled but amplified.

In relation to the present invention, in the contents of "Development of floor-friendly materials to prevent pollution" published by the Ministry of Environment in 2007, This is because the fundamental vibration of the floor structure occurs at several frequencies at low frequencies below 100 Hz. Second, the frequency characteristics of the heavy shock source This is because the lower frequency is characterized by a large energy and a decrease in frequency as the frequency increases. "As stated, the interlayer noise is not only transmitted by the upper noise, but also by the resonance phenomenon of the interlayer slab It can be seen that when the impact sound is low, it has a greater energy and sounds more loudly. In the measurement model of the development of floor-to-ceiling materials to prevent pollution (in the same report, p. 68), the area where the low-frequency resonance sound vibrates has a large space between the pillars , And it is widely distributed in a wide space of a living room or an inner room. In other words, the problem of the interlayer noise is that the low frequency sound is distributed widely by the resonance phenomenon, so that the high sound is generated, and the upper noise generating high frequency has no great influence. It is an object of the present invention to cut off a low-frequency vibration sound by simultaneously generating an anti-phase offset vibration sound centering on a central portion of the space, wherein a low-frequency vibration sound occurs at a central portion of a wide-
