Referring to FIG. 3, the user terminal 200 according to an embodiment of the present invention includes a communication module 210, a memory 220, a processor 230, and a noise frequency measurement module 240.

For the communication module 210, the memory 220, and the processor 230, descriptions that overlap with the descriptions of the communication module 110, the memory 120, and the processor 130 described above with reference to FIG. 2 will be omitted. Shall be.

In detail, the communication module 210 provides a communication interface necessary to provide a transmission / reception signal between the server 100 and the user terminal 200 in the form of packet data in cooperation with the communication network 300. Furthermore, the communication module 210 may transmit a data request to the server 100 and receive data in response thereto.

In this case, the program for recommending the sound absorbing material for blocking the noise recorded in the memory 120 and the memory 220 may be different.

The processor 230 is a kind of central processing unit that controls the entire process of recommending the sound absorbing material to block the noise. Each step performed by the processor 230 will be described later with reference to FIG. 5.

The noise frequency measuring module 240 measures a noise for recommending the sound absorbing material. In detail, it has a function of measuring noise at a specific position (measurement position) and deriving a range of frequencies.

The microphone or the module capable of measuring the noise provided in the user terminal 200 may serve as the noise frequency measurement module 240, but in a further embodiment, the noise frequency measurement module 240 is implemented as an independent device. It may be implemented in connection with the user terminal 200.

Referring to FIG. 4, the server 100 receives noise (frequency characteristics of noise) from the user terminal 200 (S410).

In this case, in addition to the noise information from the user terminal 200, whether the corresponding noise is a first soundproof mode for blocking the inflow of external noise based on the measurement position and a second soundproof mode for blocking the emission of the internal noise. Will receive.

Next, the sound absorbing material corresponding to the noise frequency is selected, and the thickness to block the noise is calculated (S420).

Of the plurality of sound absorbing materials stored in the database 140, the sound absorbing material corresponding to the noise frequency received in step S410 is selected, and the thickness required for the noise blocking is calculated. At this time, in general (first soundproofing mode), the thickness of the sound absorbing material is provided to be inversely proportional to the magnitude of the noise frequency. That is, in case of noise having a high frequency, the thickness becomes thin, and in the case of noise having a low frequency, a thick sound absorbing material may be borrowed. However, the configuration and properties that can be calculated according to the material, structure, or characteristics of the sound absorbing material may vary.

At this time, when there are a plurality of wall surfaces of a room for measuring noise, and different frequencies measured at a plurality of measurement positions corresponding to the plurality of wall surfaces are below a preset range, the same type and thickness of the same sound absorbing material that can block the noise is recommended. When the difference in frequency exceeds a preset range, sound absorbing materials having different types and thicknesses are recommended for each wall surface corresponding to the measurement position, and a construction method and a schematic image are provided.

In this case, when a plurality of frequencies are received at one measurement position and the range between the frequencies exceeds a preset range, sound absorbing materials having different thicknesses or types may be recommended for one wall surface corresponding to the measurement position. The construction method and the design image of the sound absorbing material can be provided accordingly.

If this is described in detail, the magnitude of the noise transmitted through one wall may also be different for each of the masturbation positions. Therefore, the location of the interior space where the noise having a high frequency or a low frequency may be different, it is possible to respond to such a wide range of noise characteristics by varying the type or thickness of the sound absorbing material provided on one wall.

Furthermore, the present technology may further provide a customized sound absorbing structure by additionally providing construction information of sound absorbing materials provided for each area of a space, and in further embodiments, provide a user with price information on the sound absorbing material, thereby providing a user with a cost. It may be possible to take into account aspects.

In addition, the type and thickness of the sound absorbing material that can be used can be selected according to whether the first soundproofing mode and the second soundproofing mode are used, and the construction method can be calculated accordingly.

At this time, according to the detailed request of the user terminal 200 can provide a result value in two ways, first select a plurality of sound absorbers that can block the frequency characteristics of the noise, each sound absorber can respond to the noise By calculating the thickness, a corresponding result may be generated and transmitted to the user terminal 200. This may be used to select one of various kinds of sound absorbing materials rather than the thickness of the sound absorbing materials.

Alternatively, the thickness of the general sound absorbing material for blocking noise may be calculated, and the type of sound absorbing material corresponding to the thickness may be selected and provided to the user terminal 200. In this case it can be used to provide a sound absorbing material in a room sensitive to the effective area of the indoor space.

Finally, the selected sound absorbing material is provided to the user terminal 200 (S430).

The sound absorbing material selected according to the step S420 and the thickness thereof, and the construction method (or the construction area for one wall surface) are provided to the user terminal 200.

Referring to FIG. 5, the user terminal 200 measures noise (noise frequency) at a measurement position set by a user (S510).

The user will measure the noise at the set position to measure the noise. In this case, when the user terminal 200 recognizes a sound outside the audible frequency range of the general people, the user may transmit a message to change the measurement position.

For example, when the measurement position is set at a location far from the noise generating area, the user terminal 200 may not recognize the noise. In this case, the user terminal 200 is to transmit a message to the user to move to a position capable of smooth noise measurement.

In addition, at this stage, one or more frequencies may be received. For example, the planar structure of the indoor wall to be measured, the number of the plurality of wall surfaces, and the frequency characteristics of the noise are received from a position for measuring.

This means that a room designed in the general form will have four or more walls. Therefore, the sound absorbing material can be installed only on one wall surface, but the sound absorbing material can be installed on the other surface if necessary, so that when the sound absorbing material is installed on the plurality of wall surfaces, it is necessary to set a plurality of measurement positions corresponding thereto and measure the noise.

If a plurality of noises are received in step S420, the server 100 calculates a plurality of sound absorbing material selections and thicknesses that can block the number of frequencies of the plurality of sound absorbing materials stored in the database 140. will be.

Next, the first to second soundproofing modes for selecting whether the noise to be blocked is an external or internal noise are selected and transmitted to the server 100 together with the noise information measured in step S510 (S520).

This is because the server 100, which receives the noise frequency, does not know whether the noise occurs indoors or outdoors. Therefore, the server 100 must transmit the noise frequency to the server 100 through a separate selection.

As described above, the first soundproofing mode is for preventing the noise generated from the outside from flowing into the inside, and the second soundproofing mode is for preventing the noise generated from the inside from leaking to the outside.

The server 100 selects the sound absorbing material through the received first soundproofing mode or the second soundproofing mode, and calculates the thickness.

In this case, the second soundproofing mode may cut a frequency in a wider range than the input noise frequency by applying a relational formula for calculating the thickness used between the noise frequency and the sound absorbing material after the range of the collected noise frequency is extended by a predetermined range. Choose the sound absorbing material.

Finally, the information and the thickness of the sound absorbing material are received from the server 100 (S530).

In addition, as a further embodiment, the server 100 may transmit the information on the construction method or the latest trend information to the user terminal 200.

In another further embodiment, after the installation of the sound absorbing material is completed, the noise is re-measured at the measurement position on the wall where the sound absorbing material is installed, and the difference between the noise frequencies before and after the sound absorbing material is calculated.

At this time, if the difference value of the noise frequency has a value less than the preset range, it is determined that the installed sound absorbing material does not perform the function of the noise blocking, it provides a complementary solution to solve this problem.

At this time, the complementary solution provided is to prevent the noise by recommending a sound absorbing material having a different type and thickness than the existing sound absorbing material to block the noise.

This enhances the noise blocking function by further attaching an additional sound absorbing material (for example, polyurethane) to the outer surface of the sound absorbing material already installed. This is reflected according to the user's request, and the complementary solution is stored in the server 100 for later use.

The method of suggesting a customized sound absorbing structure according to the exemplary embodiment of the present invention described above may be implemented in the form of a recording medium including instructions executable by a computer, such as a program module executed by a computer. Such recording media includes computer readable media, and computer readable media can be any available media that can be accessed by a computer and includes both volatile and nonvolatile media, removable and non-removable media. In addition, computer readable media includes computer storage media, which are volatile and nonvolatile implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Both removable and non-removable media.

The foregoing description of the present invention is intended for illustration, and it will be understood by those skilled in the art that the present invention may be easily modified in other specific forms without changing the technical spirit or essential features of the present invention. will be. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive. For example, each component described as a single type may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined form.
