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. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

It should be understood that the term " interlayer noise " used in this specification includes not only the noise between the upper layer and the lower layer, but also the noise between adjacent generations or diagonally located generations.

FIG. 1 is a schematic view of a structure of an interlayer noise control system according to an embodiment of the present invention. FIGS. 2 and 3 illustrate a method of patterning acoustic waves for generating interlayer noise according to an embodiment of the present invention Fig.

Referring to FIG. 1, the interlayer noise control system may include a noise input unit 110, a canceling wave generating unit 120, and a canceling wave output unit 130.

The noise input unit 110 may include a microphone, and converts the noise generated in the vicinity of the noise input unit 110 into an analog signal (shock wave).

The noise input unit 110 may be provided in an upper portion of a sidewall of the lower living space, a ceiling portion or an inner region of a ceiling member that separates a lower living space and an upper floor, The microphone provided to detect only a sound wave caused by the sound wave may be a directional microphone.

The canceling wave generating unit 120 includes a noise pattern analyzing and generating unit 142, a canceling wave pattern generating unit 144, a storing unit 146, a canceling wave pattern extracting unit 148 and a counterclockwise wave generating unit 150 .

The noise pattern analyzing and generating unit 142 analyzes the sound wave starting intensity (that is, the intensity of the sound wave with respect to the first impact sound), the period of the impact sound generation, the sound wave intensity per cycle, Time (i.e., the total time until the sound wave input in which the sound wave input repeatedly lasts is terminated), and the like. An example of the sound wave shape analyzed by the noise pattern analyzing and generating unit 142 is shown in FIG.

The noise pattern analyzing and generating unit 142 analyzes the noise pattern information (for example, the sound wave start intensity, the first period (that is, the time interval between the second impact sound generating time points at the time of generating the first impact sound) (I.e., the time interval between the occurrence of the individual impact sound), the average period, the intensity of the sound wave with respect to the individual impact sound, the duration, the average intensity of the sound wave at the duration, etc.) The noise pattern information may be stored in the storage unit 146 to match the assigned noise pattern identifier (e.g., the noise pattern ID) as illustrated in FIG.

Generally, the interlayer noise is a noise caused by a short-term one-shot noise in which an object is dropped and an impact sound is generated, a long-term single noise such as a toilet water (for example, a toilet water), a sound Noise of the impact sound), and the like. Here, the intermittent noise generally has a characteristic that the time of occurrence of the impact sound has a period (i.e., a certain time interval between the occurrence time of the impact sound) during the duration time, and a characteristic that occurs repeatedly in the living image (for example, The noise pattern analyzing and generating unit 142 generates noise pattern information for intermittent noises and stores the generated noise pattern information in the storage unit 146. [ Of course, in the case of a long-term single noise such as a sound of a toilet water, it is natural that the noise pattern information is generated and stored in the storage unit 146 because the noise pattern is normally fixed.

Before storing the generated noise pattern information in the storage unit 146, the noise pattern analyzing and generating unit 142 may previously store noise pattern information having similarity within the error range with the generated noise pattern information to the storage unit 146 If it is stored, the average value calculated using the newly generated noise pattern information and the previously stored noise pattern information may be stored corresponding to the noise pattern identifier assigned to the already stored noise pattern information.

The newly generated noise pattern information and the previously stored noise pattern information are determined to have similarity when they have similarity within an error range in a predetermined number or more of sound wave start intensity, period, intensity of sound wave per period, duration, And the number of times of measurement for calculating the average value (i.e., the number of times of generation of the noise pattern information) for storing the average value may be stored and managed in the storage unit 146.

The noise pattern analyzing and generating unit 142 analyzes the sound waves supplied from the noise input unit 110 to determine whether the sound wave start intensity exceeds a predetermined noise reference value, The canceling wave pattern extracting unit 148 requests the start of operation.

The request to start the operation may include, for example, the sound wave start intensity, and when information for intermittent noise is to be eliminated, information about the first cycle (i.e., the time interval between the second impact sound generation time at the first impact sound generation time point) . Of course, even in the case of intermittent noise, only the sound wave initiation intensity may be included in the request to start the operation if it is clear that the sound wave initiation intensity is changed by the weight and walking or running.

The noise pattern analyzing and generating unit 142 may be configured to generate and store the above-described noise pattern information only when a sound wave exceeding the noise reference value is input from the noise input unit 110. [ This is because it is unnecessary to determine the offset wave pattern in advance because it is recognized that the noise generated in the cutter does not affect the lower layer in the case of a sound wave below the noise reference value.

The canceling wave pattern generating unit 144 generates the canceling wave pattern information corresponding to the noise pattern information generated by the noise pattern analyzing and generating unit 142 and stores the information in the storing unit 146.

For example, the cancellation wave according to the cancellation wave pattern information may be a waveform canceling the sound wave recognized by the noise pattern information (for example, a waveform having a phase opposite to that of the noise pattern) May be generated to include information for generating an offset wave in accordance with, for example, the individual period included, the intensity of the sound wave with respect to the individual impact sound, duration, and the like.

The canceling wave pattern extractor 148 receives the canceling wave pattern information for removing the noise currently input through the noise inputting unit 110 from the storage unit 146 .

If the operation start request includes information on the sound wave start intensity and / or the first cycle, for example, the cancellation wave pattern extractor 148 searches the storage 146 for the noise pattern information corresponding to the information, And extracts the cancellation wave pattern information corresponding to the noise pattern information. For example, in the case of eliminating intermittent noises, it is possible to extract the cancellation wave pattern information by using the information about the sound wave start intensity and the first cycle. In the case of eliminating long-term monotonic noise such as toilet water It is possible to extract the cancellation wave pattern information using only the sound wave start intensity.

3, if the sound wave start intensity is analyzed as 62 db, the cancellation wave pattern extracting unit 148 extracts the cancellation wave ID R001 corresponding to the noise pattern ID N001 having the sound wave start intensity of the corresponding size The corresponding cancellation wave pattern information can be extracted.

The canceling wave generating unit 150 generates a canceling wave corresponding to the extracted canceling wave pattern information, and the generated canceling wave is outputted through the canceling wave output unit 130. The canceling wave output unit 130 may be configured to include a directional speaker, for example, and may be installed to output a canceling wave toward the noise source where the noise to be removed is generated.

As described above, the inter-layer noise control system according to the present embodiment generally uses the characteristics of the impact sound generated up to the second time in consideration of the characteristics of the intermittent noise, in which the impact sound is generated periodically, And outputting a predetermined harmonic wave in accordance with the prediction, so that the damage of the interlayer noise generated in the upper layer can be minimized.

In other words, as illustrated in FIG. 2, by the offset wave generating unit 150 and the offset wave output unit 130, in accordance with the magnitude of the impact sound and the impact sound generation period, which are normally generated at the second or third impact sound generation time, So that the damage caused by the interlayer noise can be minimized. Here, the point of outputting the first cancellation wave may be the point at which the accumulated impact sound generation cycle has elapsed from the point of time when the immediately preceding impact sound is generated, and the size of the output offset wave may be set so as to eliminate the expected impact sound immediately after the number of the impact sounds It may be the size specified in the cancellation wave occurrence information.

In addition, there is also an advantage that the optimum cancellation wave pattern information can be secured by analyzing the characteristic of the intermittent noise frequently occurred in the living state every time of occurrence and updating the noise pattern information.

Also, even in the case of a long-term single-shot noise (for example, a toilet water sound), it is possible to extract or cancel the cancellation wave pattern information corresponding to the sound wave start intensity and output the corresponding cancellation wave, thereby eliminating or minimizing the discomfort due to the long-

4 is a flowchart illustrating a method for preventing interlayer noise according to an embodiment of the present invention.

Referring to FIG. 4, in step 410, the interlayer noise control system determines whether an analog signal (shock wave) corresponding to noise generated in the surroundings is input.

If a shock wave is input, the inter-layer noise reduction system performs an analysis of the sound waves in step 415 to determine whether the sound wave start intensity exceeds a predetermined noise reference value.

If the noise reference value is exceeded, in step 420, the inter-layer noise reduction system retrieves the corresponding noise pattern information in the storage unit 146 using the sound wave start intensity and the first period of the shock wave to be input. As described above, in the case of aiming at elimination of long-term singular noises such as toilet water, only the sound wave initiation intensity may be used.

Then, in step 430, the interlayer noise control system extracts the cancellation wave pattern information corresponding to the noise pattern information from the storage unit 146, and outputs the cancellation wave corresponding to the extracted cancellation wave pattern information toward the noise source.

If the shock wave has been generated at step 410, the inter-layer noise reduction system may calculate the shock wave characteristic corresponding to the real-time input sound at step 440 (for example, sound wave start intensity, first cycle (Ie, the time interval between the occurrence of the second impact sound at the point of time), the individual period (ie, the time interval between the occurrence of the individual impact sound), the average period, the intensity of the sound wave for the individual impact sound, Which may include one or more).

Subsequently, in step 450, the inter-layer noise reduction system determines whether or not the input of noise has been completed.

If the input of the noise is retained, proceed to step 440 again.

However, if the input of the noise is terminated, the interlayer noise control system in step 460 generates noise pattern information and / or cancellation wave pattern information using the characteristics of the shock wave analyzed in step 440 and stores it in the storage unit 146. At this time, if the noise pattern information having similarity to the generated noise pattern information is already stored in the storage unit 146, a process of updating the average value with the previously stored noise pattern information may be performed.

The process of steps 440 to 460 may be performed for all the generated noises but may be set to be performed only when the output of the cancellation waves is performed only for the noise exceeding the noise reference value, will be.

FIG. 5 is a diagram schematically illustrating a structure of an interlayer noise control system according to another embodiment of the present invention, and FIG. 6 is a flowchart illustrating a method of generating interlayer noise according to another embodiment of the present invention.

5, the interlayer noise control system includes a noise input unit 110, a cancellation wave generation unit 120, a cancellation output unit 130, a message processing unit 510, and a message output unit 520 It is possible. Since the noise input unit 110, the canceling wave generating unit 120, and the canceling wave output unit 130 have been described with reference to the related drawings, only the differences will be briefly described here.

The canceling wave generating unit 120 determines whether the sound wave start intensity exceeds a predetermined noise reference value, and generates an operation start command to the message processing unit 510 when the sound wave start value exceeds the noise reference value.

The message processing unit 510 generates a designated message (for example, 'noise is generated at 803, please be careful', etc.) when receiving an operation start command from the cancellation wave generating unit 120, And transmits the generated message. The receiving place may be, for example, one or more of a month pad provided in a household corresponding to a noise source and a receiving device provided in the management room, and the device may be configured to output an alarm sound and a content thereof via a display unit have.

The generation corresponding to the noise source can be recognized as a generation corresponding to the direction in which the directional microphones are installed for the generated noise input and if the plurality of directional microphones are installed in the respective directions, May provide the message processing unit 510 with noise source information on which direction the noise is input.

FIG. 6 shows a method of notifying the occurrence of the inter-layer noise.

Referring to FIG. 6, in step 610, the inter-layer noise control system determines whether an analog signal (shock wave) corresponding to noise generated in the surroundings is inputted.

If a shock wave is input, the inter-layer noise reduction system performs an analysis of the sound waves in step 615 to determine whether the sound wave start intensity exceeds a predetermined noise reference value.

If the noise reference value is exceeded, the interstage noise protection system determines the epicenter of noise (noise source generation) in step 620. The noise source generation can be determined using, for example, the installation direction of the directional microphone to which the noise is input.

In step 630, the inter-layer noise reduction system generates a message for notifying the occurrence of the noise, and transmits the generated message to the receiving device of the wall pad and / or the management room provided in the noise source household.

Through the above-described process, the generation of the noise can be noticed in the generation generating the noise. Therefore, when there is a dispute or a dispute about the interlayer noise, the management room refers to the received message, It can induce agreement.

It is needless to say that the above-described interlayer noise prevention method may be performed in an automated procedure in a time-series sequence by a built-in program or the like installed in the digital processing apparatus. The codes and code segments that make up the program can be easily deduced by a computer programmer in the field. In addition, the program is stored in a computer readable medium readable by the digital processing apparatus, and is read and executed by the digital processing apparatus to implement the method. The information storage medium includes a magnetic recording medium, an optical recording medium, and a carrier wave medium.
