Description

Technical Field

[0001] This application relates to the technical field of sound-absorbing materials, and particularly to a method, system, device, and medium for determining console sound-absorbing materials. Background Art

[0002] Modern working environments such as command centers, control rooms, and dispatching centers generally have large spaces and long reverberation times. In such environments, multiple operators usually work simultaneously, and information equipment and communication equipment are densely arranged, resulting in mutual interference of sounds and a decrease in clarity. Long-term reverberation not only interferes with the work concentration of operators, affects the accuracy of information transmission, but also has a negative impact on the hearing and psychology of operators.

[0003] The determination of existing console sound-absorbing components is carried out by building a laboratory for acoustic measurement, calculating the surface area ratio of the original console to the sound-absorbing component, measuring the sound absorption coefficient of the console with the sound-absorbing component replaced, and finding the difference between it and the sound absorption coefficient of the original console. Multiply the surface area ratio by the difference in sound absorption coefficients to obtain the structural sound absorption coefficient, and then add this coefficient to the material sound absorption coefficient of the sound-absorbing component to obtain the target sound absorption coefficient of the candidate sound-absorbing component. Thus, the true sound-absorbing component is determined using the target sound absorption coefficient to instruct the user to replace the true original component in the target console with the true sound-absorbing component. This method does not consider that the sound absorption effect of materials does not increase linearly with the increase in the area of the sound-absorbing component, and the existing method depends on the actual site, requiring a large amount of resources and time. The above problems need to be solved. Summary of the Invention

[0038] The following is a further detailed description of this application in combination with Figure 1 - Figure 2 This application. The terms used in the embodiments of this application are only for the purpose of describing specific embodiments and are not intended to be limiting.

[0039] Refer to Figure 1 , a method for determining the sound absorption material of a console involved in this application specifically includes:

[0040] Step S1: Obtain the reverberation chamber parameters, and construct a reverberation chamber model according to the reverberation chamber parameters;

[0041] Step S2: Obtain the console parameters, construct a console model according to the console parameters, and mark the material replacement parts of the console model to obtain the marked part information;

[0042] Step S3: Obtain the coverage information, set the covering materials for the marked part information according to the coverage information, perform a frequency sweep operation on the reverberation chamber model, and obtain the first indoor average sound pressure information of the reverberation chamber model;

[0043] Step S4: When obtaining the optimal coverage information, obtain the candidate material information, replace the material of the marked component information according to the candidate material information, perform a frequency sweep operation on the reverberation chamber model, and obtain the second indoor average sound pressure information of the reverberation chamber model;

[0044] Step S5: Compare several pieces of first indoor average sound pressure information and the second indoor average sound pressure information to obtain the optimal covering material information.

[0045] Specifically, in this application, by establishing a reverberation chamber model and a console model, and performing a material test operation on the established reverberation chamber model and console model, the materials for several reverberation chamber scenarios and console test targets can be determined more conveniently and appropriately. First, mark the replaceable components of the console model to obtain the marked component information, cover the marked components with covering materials according to the obtained coverage information, and then perform a frequency sweep operation on it to obtain several pieces of first indoor average sound pressure information of the frequency sweep results. Replace the material of the marked components according to the candidate material information, and then perform a frequency sweep on it to obtain several pieces of second indoor average sound pressure information. At the same time, compare the effects of different materials and different coverage rates on the sound absorption performance of the console at each frequency, and obtain the most economical coverage rate at a certain frequency and the material with the best sound absorption effect under this coverage rate, that is, the optimal material information, so as to more accurately determine the sound absorption material of the console and improve the determination efficiency of the console sound absorption material.

[0046] As one of the implementation manners, the specific steps for setting the covering material for the marked component information according to the coverage information are as follows:

[0047] Obtain the preset covering order information, and set the covering material for each of the several pieces of marked component information one by one according to the coverage information and the preset covering order information.

[0048] The specific steps for performing a frequency sweep operation on the reverberation chamber model to obtain the first indoor average sound pressure information of the reverberation chamber model are as follows:

[0049] Perform a frequency sweep operation on the marked component information from 500 to 2000 Hz to obtain the first indoor distributed sound pressure information of the reverberation chamber model;

[0050] Perform an average value analysis according to the first indoor distributed sound pressure information to obtain the first indoor average sound pressure information.

[0051] Specifically, in the embodiment of this application, first, a standard reverberation chamber and a model including the original console are modeled, all components on the console that can be used to replace the sound absorption material are defined and marked, and the total outer surface area of all replaceable sound absorption material components and the specific surface area of each independent sound absorption component are calculated by the surface integral method.

[0052] Among them, when obtaining the coverage information, the covering material is set to place a sound source with a power of 1 watt at a corner in the reverberation chamber model, and the reverberation chamber is subjected to a swept-frequency measurement from 500 to 2000 Hz. At each frequency, according to the proportion of the surface area of the sound-absorbing component in the total replaceable sound-absorbing component surface area of the console, following the principle of dispersed arrangement of the sound-absorbing material, after increasing the material coverage rate by about 10% each time, the average sound pressure value is calculated by integrating the sound pressure distribution in the reverberation chamber until the sound-absorbing material coverage rate reaches 100%. By gradually increasing the proportion of the sound-absorbing material in the experiment, a change curve of the sound pressure in the reverberation chamber decreasing with the increase of the sound-absorbing material coverage area at different frequencies can be obtained. This curve also reflects the change trend of the sound-absorbing performance of the console, so as to select the best coverage rate from several first indoor average sound pressure information.

[0053] As one of the implementation manners, the preset coverage order information is set to sequentially select the marked components in the clockwise direction from the top of the console model.

[0054] Specifically, in the embodiment of the present application, the coverage rate of the sound-absorbing material is gradually increased in the clockwise direction starting from the top of the console. Specifically, the first top is covered first, then the first front is covered, then the left side is covered, then the first back is covered, then the right side is covered, then the bottom is covered, then the second top is covered, then the second front is covered, and then the second back is covered. Among them, the difference between the first and second components lies in different areas within the same part range.

[0055] In the embodiment of the present application, starting from the top of the console, each component is gradually covered in the clockwise direction, so that the coverage rate of the sound-absorbing material for each part gradually increases, reducing the problem of insufficient coverage of a certain part. By covering from the top to the bottom and from the front to the back, each component can be evenly concerned and processed during processing, avoiding neglect of local areas.

[0056] Moreover, there are different areas within the same part range for the first and second components in the embodiment of the present application. By covering one by one, the covering intensity or method can be adjusted according to the needs of different areas in a targeted manner, thereby effectively improving the use efficiency of the material and the sound-absorbing effect, making the determination process more linear to a certain extent and making the determination of the best coverage rate point more accurate.

[0057] As one of the implementation manners, the preset coverage order information further includes 10 - 100% of the total area coverage rate of the marked components, and each time it increases by 10%.

[0058] Specifically, the embodiments of the present application gradually cover the sound-absorbing material, which can evenly lay the sound-absorbing material in different parts, contributing to the improvement of the overall sound-absorbing effect. Especially in the case where different regions need to be processed, gradually increasing the coverage rate of the sound-absorbing material in sequence can reduce the occurrence of excessive or insufficient local materials, and further improve the overall effect.

[0059] As one of the implementation manners, several average sound pressure information in the second chamber are compared to obtain the best material information. By observing the change curve, it can be found that the sound-absorbing performance of the material does not have a linear relationship with the increase in area. Usually, after the area increases to a certain critical value, the improvement of the sound-absorbing effect gradually weakens, that is, the curve presents an inflection point. This inflection point reveals the change in the marginal benefit of increasing the material coverage rate on the sound-absorbing effect. By comparing the sound-absorbing performance at the inflection point of the sound-absorbing curves of different materials at the same frequency, the optimal material combination and its economically effective coverage rate at a specific frequency can be determined.

[0060] As one of the implementation manners, it further includes:

[0061] Obtain the material distribution information, adjust the material coverage parts of the console model according to the material distribution information, perform a sweep frequency operation on the reverberation chamber model, and obtain the average sound pressure information in the third chamber of the reverberation chamber model;

[0062] Compare several average sound pressure information in the third chamber to obtain the best layout information.

[0063] Specifically, the embodiments of the present application determine the best layout method of the sound-absorbing material in the console to optimize the sound-absorbing performance. Through computer modeling, a reverberation chamber model is created, which includes a point source with a power of 1 watt and a digital model of the console. According to the economically effective material area ratio at a specific frequency determined above, while keeping the total area of the sound-absorbing material unchanged, three material layout schemes are designed. Specifically, one is that the material is all arranged near the top of the console, another is that the material is all arranged at the bottom, and the last one is that the material is evenly and dispersedly arranged. Under each layout scheme, by integrating the sound pressure distribution at different frequencies in the reverberation chamber, the average sound pressure value is calculated to analyze the influence of different layout schemes on the indoor sound pressure, so as to select the layout method with the best sound-absorbing effect, enabling more accurate determination of the sound-absorbing material of the console and improving the determination efficiency of the sound-absorbing material of the console.
