Description

Technical Field

[0001] The present application relates to the field of computer simulation acoustics, and in particular to a method for determining a sound-absorbing material of a console based on computer simulation. Background Art

[0002] As the demand for information integration and efficient command in modern command centers, control rooms, and dispatch centers continues to grow, the requirements for operator efficiency, comfort, and long-term health are also increasing. However, these environments usually have multiple operators working at the same time, and information equipment and communication equipment are highly dense, resulting in a complex acoustic environment and high noise levels. This not only interferes with the operator's concentration and reduces the accuracy of information transmission, but may also have adverse effects on the operator's hearing health and psychological state.

[0003] In this context, speech intelligibility, as an important indicator for measuring the quality of acoustic environment, is affected by multiple factors such as noise, sound absorption performance of materials, and sound wave propagation path, and has become one of the key problems in acoustic environment design. In acoustic environment design, the selection of sound-absorbing materials for consoles is a key link. The traditional method of selecting sound-absorbing materials for consoles has the problems of cumbersome operation, low efficiency, and large errors. For example, in most existing technologies, it is necessary to construct a spatial model for each candidate sound-absorbing component separately and replace it one by one for calculation, which makes the calculation complicated and time-consuming, especially when there are a large number of candidate materials, which significantly increases the cost. Moreover, the method of measuring the sound absorption coefficient based on reverberation time is greatly affected by the size of the sound-absorbing material, and has defects such as edge effect, Sabine formula approximation error, and difficulty in meeting the sound field conditions, resulting in poor repeatability of the measurement results and increased errors. More importantly, when the sound absorption coefficient of the candidate sound-absorbing component is low, the calculated target sound absorption coefficient may be lower than the actual value, and the optimal sound absorption effect cannot be guaranteed. In addition, the existing technology also has the problem of being unable to quantify the degree to which the best sound-absorbing component improves the overall sound absorption effect of the console, making it difficult to provide a reliable basis for optimization selection.

[0004] Therefore, how to quickly and accurately evaluate the sound absorption performance of different sound absorption material combinations, so as to optimize the selection of sound absorption materials for the console and improve the sound absorption and noise reduction effects of the console, is an urgent problem to be solved.

[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] In one embodiment of the present application, a method for determining the sound absorbing material of a console based on computer simulation is provided. Figure 1 As shown, the method includes:

[0049] S100: Acquire a sound absorbing material assembly, and perform computer modeling on the sound absorbing material assembly.

[0050] Specifically, candidate sound absorbing material assemblies are obtained, such as porous materials, perforated plates and cavity sound absorbing material assemblies, and computer modeling is performed on the assemblies so that the assemblies become models that can be subjected to computer acoustic simulation, such as sound absorbing material samples used in standing wave tube models.

[0051] S200: changing the acoustic structural parameters of the sound absorbing material assembly.

[0052] Specifically, each time a single physical quantity of a certain material in the sound absorbing material assembly is changed, the single physical quantity may be the thickness of the perforated plate, the porosity, the depth of the cavity or the thickness of the porous material, etc., the single variable is controlled to adjust the acoustic structure parameters one by one, and a series of sound absorbing material assemblies with different combinations of acoustic structure parameters are generated, and these different assemblies are input as a set into step S300.

[0053] S300: Calculating the sound absorption coefficient of the sound absorbing material assembly with different acoustic structural parameters by using a transfer function method; obtaining the structure of the console, and establishing an original console model according to the structure of the console.

[0054] Specifically, the transfer function method is a mathematical method used to analyze the dynamic characteristics of a system. In the field of acoustics, the transfer function is used to describe the attenuation and phase change of sound waves when they propagate through different media (such as air, materials). By measuring the relationship between the input signal and the output signal, the transfer function of the system can be calculated, and then the sound absorption performance of the material can be analyzed.

[0055] In this step, the transfer function may be a ratio of the sound pressures of multiple microphones. This transfer function reflects how the sound absorbing material affects the propagation characteristics of the sound wave during the propagation of the sound wave from one microphone to another.

[0056] After calculating the sound absorption coefficient of the sound absorbing material assembly with different acoustic structural parameters by using the transfer function method, the structure of the control console is obtained. The control console is a physical space or structure containing various electronic devices and operation interfaces, which are often used in modern command centers, control rooms or dispatch centers. These devices may generate noise and affect the work efficiency and comfort of operators.

[0057] According to the spatial structural characteristics of the console, a three-dimensional model is constructed in the computer to obtain original console models of different structures. The original console model reflects the three-dimensional geometric shape of the actual console, including its height, width, depth and the inclination angle of each panel, and includes the simulation of the material properties of each part of the actual console, including the material density, elastic modulus, Poisson's ratio and other physical parameters. Moreover, in the original console model, according to actual needs, the parts that can be replaced by the combination of sound absorbing materials are marked.

[0058] S400: Substituting the sound absorption coefficient into the parts of the original console model that can be replaced by the sound absorption material assembly to obtain multiple console models.

[0059] Specifically, the sound absorption coefficients of the candidate sound absorption material combinations are assigned to the replaceable sound absorption module parts of the console to obtain the console model. This eliminates the need to construct a spatial model for each candidate sound absorption component, significantly improves the selection efficiency, and reduces the complexity of the calculation process.

[0060] S500: calculating the sound absorption effect of the console model at different frequencies by frequency sweeping; and determining the sound absorption material combination selected for the console model at different frequencies based on the sound absorption effect.

[0061] Specifically, the frequency sweep calculation is a method for evaluating the response of a system at different frequencies by changing the frequency of the input signal. In acoustic simulation, the frequency sweep calculation is used to evaluate the acoustic performance of a reverberation room or console model at different frequencies. By gradually changing the frequency of the input signal and measuring the response characteristics of the output signal (such as sound pressure level, reverberation time, etc.), the acoustic performance of the system at different frequencies can be fully understood.

[0062] The control console model is subjected to frequency sweeping to obtain a sound absorption effect, which can be measured by a variety of indicators, such as the attenuation degree of the sound pressure level, the average sound pressure level, and the like.

[0063] Finally, according to the sound absorption effect, the sound absorption material combination with the best sound absorption performance at different frequencies for a console model is screened out, so as to determine the sound absorption material combination selected at this frequency.

[0064] In this embodiment, the combination of sound-absorbing materials is evaluated and selected as a whole by computer simulation technology, rather than building a spatial model for each candidate sound-absorbing component one by one, which significantly improves the selection efficiency, reduces the complexity of the calculation process, and effectively reduces the consumption of computing resources. In addition, the present application can also build an original console model of the corresponding structure according to the actual use space characteristics of the console, and then combine the material combination corresponding to the specific sound absorption coefficient to generate a highly targeted sound-absorbing component, further improving the overall sound absorption effect and noise reduction performance of the console, and improving the work efficiency and comfort of the operator.

[0065] In some embodiments, the step of changing the acoustic structural parameters of the sound absorbing material assembly and calculating the sound absorption coefficient of the sound absorbing material assembly with different acoustic structural parameters by using a transfer function method comprises:

[0066] By changing a single physical parameter of a material in the sound absorbing material assembly through parametric scanning, a sound absorbing material assembly with different acoustic structural parameters is obtained;

[0067] The transfer function method is used to calculate the sound absorption coefficient of the sound absorption material assembly with different acoustic structural parameters.

[0068] In specific implementation, a parametric scanning method is adopted to adjust the acoustic structural parameters of the materials in the sound-absorbing material assembly one by one by controlling a single variable, so as to generate a series of sound-absorbing material samples with different parameter combinations.

[0069] In this embodiment, by using parameter scanning technology in computer simulation to continuously change the model parameters of the acoustic structure, such as pore size, perforation rate, plate thickness, etc., a high-performance sound-absorbing structure can be quickly found, avoiding repeated experiments and calculations in traditional methods and improving the accuracy and efficiency of optimization.

[0070] In some embodiments, it also includes:

[0071] Screening the sound absorption coefficient according to a preset threshold;

[0072] The sound absorbing material combination corresponding to the screened sound absorption coefficient is used as a preferred material;

[0073] The preferred materials are substituted into the original console model.

[0074] During specific implementation, the preset threshold may be determined based on historical modeling data.

[0075] In this embodiment, by further screening the sound absorption coefficient and then bringing the screened materials into the original console model, the sound absorption effect can be controlled within an approximate range, thereby improving the efficiency of determining the combination of sound absorption materials.

[0076] In some embodiments, the step of calculating the sound absorption effect of the console model at different frequencies by frequency sweeping includes:

[0077] Constructing a reverberation room model, and placing the console model into the reverberation room model;

[0078] Set a point sound source in the reverberation room model and perform frequency sweep calculations;

[0079] Obtain acoustic response data at different frequencies in the reverberation room model;

[0080] The sound absorption effect of the console model at different frequencies is determined according to the acoustic response data.

[0081] In specific implementation, a point sound source with a power of 1 watt is placed in a corner of the reverberation chamber to simulate the propagation behavior of an actual sound source in space. Subsequently, a frequency sweep calculation is performed from 500 Hz to 2000 Hz, for example, to capture the acoustic response data at different frequencies in the reverberation chamber by gradually scanning within the frequency range.

[0082] In this embodiment, by constructing a reverberation room model, a variety of specific acoustic structures can be quickly generated based on console models of various different materials, and their acoustic performance can be quickly evaluated, which meets the evaluation of consoles of different structures or positions in practical applications. In addition, this process can also improve the clarity of speech in the sound field, reduce unnecessary sound reflections and noise interference, optimize the sound field environment, thereby improving the clarity and intelligibility of the sound, and provide practical guidance for customers to replace the corresponding modules of the original console with the specified sound-absorbing material combination in actual applications, ultimately effectively improving the sound absorption and noise reduction effect of the console and improving the transmission quality of the sound.

[0083] In some embodiments, determining the sound absorption effect of the console model at different frequencies according to the acoustic response data includes:

[0084] Integrating the sound pressure level of the entire reverberation chamber space in the acoustic response data;

[0085] Calculate the average sound pressure level based on the integration result;

[0086] The sound absorption effect of the console model at different frequencies is determined according to the attenuation degree of the average sound pressure level at different frequencies.

[0087] In specific implementation, the sound energy attenuation effect of each sound absorbing material combination at different frequencies can be obtained based on the acoustic response data, so as to evaluate the sound absorption performance of different materials and determine the material combination with the best sound absorption performance at different frequencies for a specific console model.

[0088] In this embodiment, the relative difference of the average sound pressure level of the steady-state sound field is used to evaluate the sound absorption performance, which avoids the defects of the traditional sound absorption coefficient calculation method based on the reverberation time. By directly measuring and comparing the sound pressure level reduction effects of different materials in the same sound field, the accuracy and reliability of the evaluation are improved.

[0089] In some embodiments, taking the sound absorbing material combination of "porous material, perforated plate and cavity sound absorbing material combination" as an example, the sound absorption coefficient of this sound absorbing material combination at different frequencies and the influence of these material combinations on the sound absorption effect of a specific console are evaluated.

[0090] Specifically, it is divided into two steps. Step one includes the establishment of a standing wave tube model and the calculation of the material sound absorption coefficient, and step two includes the establishment of a console model and the evaluation of the sound absorption effect.

[0091] The specific steps of step one are:

[0092] (1) Using computer simulation software, a three-dimensional model of a cylindrical standing wave tube is established. The diameter of the standing wave tube is set to 100 mm and the length is 2000 mm to simulate the acoustic environment that may be encountered in actual applications.

[0093] (2) A loudspeaker is placed at one end of the standing wave tube to generate a sound wave signal; a sample of the sound-absorbing material to be tested is placed at the other end to simulate the acoustic response of the sound-absorbing material in the pipe.

[0094] (3) Inside the standing wave tube, two fixed microphones (respectively marked as microphone p1 and microphone p2) are arranged along the axial direction, and the fixed distance between microphones p1 and p2 is 80 mm. This layout design can ensure that the details of sound wave propagation can be captured at different spatial positions, and then the effect of the sound absorbing material can be analyzed.

[0095] (4) A sound absorbing material assembly consisting of a porous material, a perforated plate and a cavity is configured, and key parameters (such as the thickness d1 and porosity p of the perforated plate, the depth d3 of the cavity, and the thickness d2 and flow resistivity σ of the porous material, etc.) are set as variable parameters.

[0096] (5) A parametric scanning method is used to adjust the above parameters one by one by controlling a single variable to generate a series of sound-absorbing material samples with different parameter combinations, and their sound absorption coefficients are measured using a standing wave tube.

[0097] (6) The sound absorption coefficient is calculated using the transfer function method. The transfer function H12 is defined as the ratio of the sound pressure at microphone p2 to the sound pressure at microphone p1, that is, H12 = p2 / p1. By analyzing the changes in the sound pressure level at different positions in the tube, the sound reflection coefficient r of the material surface is calculated, and then the sound absorption coefficient α(f) is calculated.

[0098] The specific steps of step 2 are:

[0099] (1) Create an accurate model of the reverberation chamber and control console in computer simulation software.

[0100] (2) Import the sound absorption coefficients of several better candidate sound absorbing material combinations calculated in the first step into the console model, and assign these sound absorption coefficients to the module areas of the console that can be replaced by sound absorbing materials, while keeping the sound absorption coefficients of other surfaces of the console constant.

[0101] (3) A point sound source with a power of 1 watt is placed in a corner of the reverberation chamber to simulate the propagation behavior of an actual sound source in space.

[0102] (4) Perform frequency sweep calculations from 500 Hz to 2000 Hz, and capture the acoustic responses at different frequencies in the reverberation chamber by gradually scanning within the frequency range.

[0103] (5) The average sound pressure level of the reverberation room space is calculated by integration, that is, the average sound pressure level of different frequencies in the sound field of the reverberation room after the sound source makes a sound and the sound field in the reverberation room is affected by the combination of different sound-absorbing materials.

[0104] (6) Compare and analyze the sound absorption effects of different sound-absorbing material combinations at the same frequency, and select the material combination with the best sound absorption performance.

[0105] This application also provides a device for determining the sound absorbing material of a console based on computer simulation, see Figure 2 As shown, the device comprises:
