Here, the reference sound collector management unit 1110 manages the related information including the position information on the reference sound collector 110. The reference sound collector information input unit 1120 receives the reference sound collector information received by the reference sound collector 110. The reference collection information processing unit 1130 processes the inputted reference collection information.

The reference sound collector management unit 1110 includes a reference sound collector registration unit 1111 and a reference sound collector DB 1112.

Here, the reference sound collector registering unit 1111 registers the necessary information related to the reference sound collector 110, including the position information of the reference sound collector 110. [ The reference sound collector DB 1112 stores information registered by the reference sound collector register 1111. The reference collection information processing unit 1130 includes a reference collection information analysis unit 1131 and a noise space map generation unit 1132.

The reference collection information analysis unit 1131 analyzes the reference collection information. The reference collecting information analyzing unit 1131 can generate analysis information for each wavelength band, noise intensity information, and pattern information for each time unit of noise with respect to reference collecting information.

The noise space map generating unit 1132 generates a map related to the spatial distribution of the noise with respect to the predetermined space around the reference sound collector 110 based on the analysis results of the reference sound collector information analyzing unit 1131. The active noise generator management unit 1200 includes an active noise generator registration unit 1211.

The active noise generator registration unit 1211 registers all pieces of information related to the active noise generator 130, such as location information, owner information, and location information on the active noise generator 130.

The information of the active noise generator 130 registered in the active noise generator registration unit 1211 is stored in the active noise generator DB 1212. The active noise generator management unit 1200 may include an active noise generator control unit 1220.

[

The active noise generator control unit 1220 may be configured to control the noise level of the sound emitted by the reference sound collector 110 when the noise level of the reference sound collector 110 analyzed by the reference sound collector information analyzing unit 1131 exceeds a predetermined operation stop reference, And generates a command to start the operation of the active noise generator 130 and transmits the generated command to the active noise generator 130. [

 Also, although not shown, a stop or start command of the active noise generator 130 is input through a user terminal such as a user's mobile terminal through the wired / wireless network 5000, and the inputted command is transmitted to the active noise generator 130 Can be performed.

The active noise generator 130 may be manually turned off when leaving the space in which the active noise generator 130 is installed but may be turned off through a user terminal such as a smart phone The operation of the active noise generator 130 can be stopped.

The active noise information control unit 1300 uses the analysis information of the reference sound collection information analysis unit 1131 and the noise space map information of the noise space map generation unit 1132 to calculate a predetermined noise at the position of the active noise generator 130 And generates estimation information.

The noise estimation information refers to the position information of the active noise generator 130 to generate the estimated noise information generated at the position of the active noise generator 130 on the noise space map.

The estimated noise information includes noise intensity information and noise wavelength distribution information for each time interval estimated from the noise space map information corresponding to the three-dimensional position information coordinate area of the active noise generator 130.

The active noise information generation unit 1320 generates active noise information for effectively canceling noise based on the noise estimation information based on the noise estimation information corresponding to the position of the active noise generator 130. [

Meanwhile, the active noise information transmitting unit 1330 transmits the generated active noise information to the active noise generator 130 through the wired / wireless network 5000. The noise space map generator 1132 generates a noise space map for a three-dimensional space using the sound information input from the reference sound collector 110. The method of generating the noise space map is based on the estimation of how the noise energy is spatially distributed from the noise source.

A method for generating the noise space map by the noise space map generating unit 1132 is as follows.

The noise space map generating unit 1132 analyzes the noise intensity collected by at least three reference sound recorders 110 with respect to noise wavelengths that are equal to or greater than a predetermined noise intensity with respect to the noise received by the noise space map generating unit 1132, . The noise energy of one noise source to which the reference sound collector 110 is input is determined inversely proportional to the square of the distance between the noise source and the reference sound collector 110. [

For example, when the intensity of noise of a specific frequency received by the reference sound collector a is 4 A and the intensity of the noise received by the reference sound collector b is A, the reference sound collector a is two times closer to the noise source than the reference sound collector b . The reference sound collector a and the reference sound collector b are provided on one side and the number of points corresponding to the distance ratio of 1: 2 to the reference sound collector a and the reference sound collector b is numerous. If the intensity of the noise received by the reference sound collector c is 1 / 4A, the reference sound collector a and the reference sound collector c are at a distance ratio of 1: 4.

In this way, the position of the noise source is estimated.

When the position of the noise source is estimated and the noise energy received by the reference sound collector 110 is calculated, the noise energy generated by the noise source can be calculated. In this way, the position of n noise sources (n is a natural number) and the generated noise energy are estimated.

In the case where the reference sound collector 110 and the noise source are located at the same or equal height (a normal noise is generated near the ground surface), at least three reference sound recorders 110 are used for the position estimation of the noise source. When the noise source and the height of the reference sound recorder 110 are different, at least four reference sound recorders 110 are required.

The noise space map generating unit 1132 can generate the noise space map when the position of the noise generation estimating circle and the noise energy generated by the noise generation estimating circle are determined. In the absence of a building, the noise energy is spread in three dimensions, so that the noise energy is reduced in inverse proportion to the square of the distance of the noise source.

Since the noise source is close to the surface of the earth and the noise is not transmitted well below the surface of the earth except for a special case, the noise energy at the estimated position is inversely proportional to the square of the distance , And doubles. This is because the surface area of the virtual spherical surface where the noise energy propagates due to the presence of the ground surface is 1/2.

When there is a building, the spatial distribution of noise energy is calculated by inputting the actual building conditions such as the ratio of the location of the building to the noise energy absorbed by the surface of the building, the absorption or reflection of the outer wall of the building, Of course, you can create maps.

The spatial distribution of the noise is calculated for each noise source in the same manner as described above. When the spatial distribution of the noise is processed for each noise source, the entire noise space map is completed. The generated noise space map may be generated for each wavelength / wavelength band of the noise source. It is possible to generate noise estimation information for each wavelength / wavelength band of the active noise generator 130 through the noise estimation information generation unit 1310 using the generated noise spectrum map for each wavelength / wavelength band.

The active noise information generating unit 1320 may generate active noise information corresponding to the noise estimation information for each wavelength / wavelength band generated.

As a special case, the position of the noise source may be shifted. This is especially true in the case of a roadside where a moving vehicle is a major source of noise and the speed at which the vehicle runs varies, so that the moving speed and noise energy are different for each noise source. If the car moves at a certain speed, the wavelength will change due to the Doppler effect.

When the reference sound collector 110 measures the Doppler effect, the moving speed of the noise source can be calculated. Accordingly, it is possible to generate a noise space map in which the distribution of noise energy for each noise source varies with time considering the moving speed.

However, if the collecting speed of the reference sound collector 110 and the information processing speed of the active noise control system are sufficiently fast, for example, if information is processed in units of 1/10 second or 1/100 second, It can be handled as a stationary noise source at each information processing point.

The reference collection information analyzing unit 1131 analyzes the average noise intensity of each noise wavelength received for each time interval and treats it as homogeneous noise when the variance value of the noise intensity for each noise wavelength per time zone falls within a preset range . In this case, for the homogeneous noise, the active noise information generation unit 1320 generates homogeneous active noise information for each wavelength.

The reference sound collection information analyzing unit 1131 analyzes the sound collection information by a predetermined time unit and determines whether the noise intensity of the sound waves is out of a predetermined range or a noise of a specific sound wavelength is newly generated at a predetermined level or more, If the noise is lost, the generation of the noise fluctuation may be transmitted to the noise estimation information generation unit 1310 or may be transmitted to the active noise information generation unit 1320 so that active noise corresponding to the changing situation may be generated .

The active noise control system generates active noise information to be generated by the active noise generator 130 for each of the active noise generators 130 and transmits the generated active noise information to the active noise generator 130. If there are two or more active noise generators 130 in one household, the active noise control system may generate active noise information that is different according to the positions of the active noise generators 130.

This is especially true when the furniture is an apartment which is in contact with one side of the road and the other side of which is not in contact with the road and there is a window on the side of the road and a window on the side of the road, Is required.

In the active noise control system, the user may register detailed relative position information for each active noise generator 130. The active noise generator registration unit 1211 receives various information related to the active noise generator 130 through the wired / wireless network 5000.

The information of the registered active noise generator 130 may include at least one of a physical address, a location, a height (number of floors of the house), the number of the active noise generators 130, a location of each active noise generator 130, The environment where the active noise generator 130 is located, such as whether the noise generator 130 is on the road side, or the like. The information of the registered active noise generator 130 is stored in the active noise generator DB 1212.

On the other hand, the reference sound collector registering unit 1111 receives all information related to the reference sound collector 110. The information related to the reference sound recorder 110 includes location information (including height information) of the reference sound recorder 110, zone information (e.g., apartment complexes), and surrounding environment information on the area where the reference sound recorder 110 is installed , And this information is stored in the reference sound mixer DB 1112.
