Detailed implementation manners

[0032] The embodiment of the present invention provides a configuration method, system, device and storage medium of a multi-room audio system. By constructing an acoustic model and analyzing acoustic characteristics, the channel allocation and volume adjustment of each audio device are realized, so as to improve the accuracy of parameter adjustment of each audio device in the audio system.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0034] It can be understood that the execution subject of the present invention can be a multi-room audio system, or a terminal or a server, and specific limitations are not made here. The embodiment of the present invention takes the server as the execution subject as an example for illustration.

[0035] For the convenience of understanding, the specific process of the embodiment of the present invention is described below. Please refer to Figure 1 , an embodiment of the configuration method of the multi-room audio system in the embodiment of the present invention includes: 101. Obtain the spatial layout information of each room, the physical position information and performance parameters of each audio device; Use a variety of built-in or external sensor devices, including space measuring instruments and GPS locators, to capture the spatial layout features of each room, such as size, shape, and wall material. The space measuring instrument uses laser ranging or ultrasonic ranging technology to accurately measure the geometric dimensions of the room, while the detection of wall material relies on special optical sensors that can analyze the light reflected from the wall to infer the material type and thickness of the wall. At the same time, in order to obtain the specific placement of each audio device, you can use GPS locators or indoor positioning technologies, such as Bluetooth low-power beacon systems, which can provide high-precision location information of the device in three-dimensional space. In terms of obtaining the performance parameters of audio equipment, you can obtain key performance indicators such as model, power, frequency response range, impedance, etc. by directly communicating with the device or querying the device database.

[0036] 102. Construct an acoustic model including multiple rooms and audio devices based on the spatial layout information of each room, the physical location information and performance parameters of each audio device; According to the spatial layout information of the room, which includes but is not limited to size, shape, wall material and furniture layout, a geometric model of the room is established. The geometric model will restore the real environment as much as possible to ensure the accuracy of the subsequent simulation results. Then, according to the physical location information and performance parameters of the audio device, the device model is embedded in the geometric model of the room, and the corresponding emission and reception characteristics are set. In the process of building the acoustic model, various effects such as reflection, absorption and scattering are generated by the interaction of sound waves with different materials during propagation. In order to simulate these effects, the parameters in the material database, such as reflection coefficient, absorption coefficient and scattering coefficient, can be used to set the acoustic properties of materials such as walls, floors and ceilings in the geometric model. According to the performance parameters of the audio device, such as frequency response range, power and impedance, the emission and reception process of the audio signal is simulated, and an acoustic model close to the real environment is finally generated by continuously adjusting and optimizing the model parameters. This acoustic model can not only reflect the acoustic coupling relationship between rooms, but also accurately describe the signal transmission characteristics of audio devices.

[0037] 103. Analyze the acoustic coupling relationship between different rooms and the signal transmission characteristics of each audio device based on the acoustic model to obtain an acoustic characteristic parameter set; Using parameters such as sound pressure level distribution, phase difference, and frequency response in the acoustic model, calculate the acoustic coupling strength between rooms. Specifically, using the sound pressure level distribution parameter in the acoustic model, simulate the process of sound waves propagating from one room to another. By calculating the attenuation of sound waves when passing through structures such as walls and the reflection and superposition effects in different rooms, obtain the sound pressure level distribution in the target room. Compare the differences in sound pressure levels between the source room and the target room, as well as the phase difference and frequency response changes when the sound waves reach the target room. Use these parameters to construct a mathematical model of the acoustic coupling coefficient, and apply numerical calculation methods such as finite element analysis or boundary element method to solve this mathematical model, thereby calculating the acoustic coupling strength between rooms. The value of the acoustic coupling strength reflects the degree of propagation and mutual influence of sound waves between different rooms.

[0038] Using the device model in the acoustic model, combined with the performance parameters of each audio device, such as frequency response range, power, and impedance, etc., to simulate the emission and reception process of audio signals. By calculating the attenuation and phase change of the signal during transmission, the signal transmission efficiency of the device can be evaluated, and potential distortion sources can be identified.

[0039] After obtaining the analysis results of the acoustic coupling relationship and signal transmission characteristics, integrate these data into an acoustic characteristic parameter set. The acoustic characteristic parameter set includes the coupling coefficient between rooms, the transmission loss and distortion degree of the device, etc., which can reflect the performance of the audio system under different configurations.

[0040] 104. According to the acoustic characteristic parameter set, optimize the channel allocation and volume adjustment of each audio device to obtain an optimized audio configuration parameter set; According to the calculation result of the acoustic coupling strength, evaluate the influence of sound wave propagation between different rooms. For room pairs with strong acoustic coupling, identify the audio devices that may cause mutual interference and record them; based on the result of the acoustic coupling influence evaluation, adjust the layout and power settings of the audio devices. For devices that may cause interference, their positions can be changed or the power can be adjusted to reduce the direct propagation of sound waves between rooms. According to the frequency response characteristics of the audio device, adjust its power output to ensure the stability and clarity of the audio signal during transmission.

[0041] At the same time, use signal processing strategies such as equalizers and phase correction algorithms to compensate for the distortion caused by device performance differences and room acoustic characteristics. After each adjustment, evaluate the performance of the audio system. By continuously collecting and analyzing key quality indicators such as signal-to-noise ratio, distortion degree, and dynamic range, make corresponding fine-tuning of the configuration parameters. After multiple iterations and optimizations, until the best combination of power distribution, frequency response adjustment, and phase correction parameters is found, and finally output a comprehensive and accurate optimized audio configuration parameter set.

[0042] 105. Automatically configure the channel allocation, volume adjustment, and audio signal transmission path of the multi-room audio system according to the optimized audio configuration parameter set.

[0043] Send the optimized audio configuration parameters to each audio device. At the same time, monitor the operating status of the audio system to ensure that all audio devices work as expected. If any abnormal situation is found or new requirements are put forward by the user, immediate adjustments and optimizations are made to ensure that the audio system always remains in the best state.

[0044] In the embodiment of the present invention, by collecting the room layout, the positions and performance parameters of audio devices, constructing an acoustic model, and analyzing the acoustic coupling and signal transmission characteristics, an acoustic characteristic parameter set is obtained, thereby intelligently optimizing the channel allocation and volume adjustment of audio devices, improving the accuracy of parameter adjustment of each audio device in the audio system, and significantly enhancing the sound quality and user experience of the multi-room audio system.

[0045] Please refer to Figure 2 , another embodiment of the configuration method of the multi-room audio system in the embodiment of the present invention includes: 201. Obtain the spatial layout information of each room, the physical position information and performance parameters of each audio device; Obtain the spatial layout information of each room by using sensors to obtain the spatial dimensions, shapes, and obstacle distribution information in the room; obtain the physical position information of each audio device by using a positioning system to obtain the specific installation position information of each audio device in the room; obtain the performance parameters of each audio device by querying the device specification table.

[0046] In order to obtain the spatial dimensions, shapes, and obstacle distribution information of each room, corresponding sensors can be used. These sensors include but are not limited to laser rangefinders, infrared sensors, and ultrasonic sensors, which can accurately measure the boundaries, corners, ceiling heights, and obstacle positions in the room. For example, a laser rangefinder can emit a laser beam and measure the time it takes to reflect back, thereby calculating the dimensions and shape of the room; an infrared sensor can sense the object contours in the room to help understand the obstacle distribution. In addition, the layout information of the room can also be extracted by capturing images in the room with a camera and using image processing techniques. The data collected by these sensors is processed and analyzed to generate the room spatial layout information.

[0047] To determine the physical location of an audio device, a positioning system can be adopted. These positioning systems include, but are not limited to, technologies such as GPS positioning, Bluetooth positioning, and Wi-Fi positioning, which can track the precise coordinates of the audio device within a room. For example, a GPS positioning system can receive signals from satellites and calculate the longitude and latitude coordinates of the device; a Bluetooth positioning system determines its location by measuring the signal transmission time between the device and multiple Bluetooth base stations. In addition, sensors such as an inertial navigation system and a magnetometer can be used to assist in positioning, improving the accuracy and stability of positioning. Through these positioning systems, the precise installation location of the audio device can be obtained, including its height, direction, and tilt angle, etc.

[0048] To obtain the performance parameters of each audio device, the device specification sheet can be queried. The device specification sheet is usually provided by the device manufacturer and contains the detailed performance parameters of the device. The performance parameters include, but are not limited to, frequency response, power output, impedance, and sensitivity. These performance parameters determine the performance of the audio device in different acoustic environments. For example, the frequency response determines the audio frequency range that the device can reproduce; the power output determines the volume size of the device. By querying these specification sheets, the performance characteristics of each audio device can be understood, enabling more precise optimization and configuration. In addition, professional test equipment can be used to actually test the audio device to obtain more accurate performance parameters.

[0049] 202. Based on the spatial layout information of each room, the physical location information, and performance parameters of each audio device, construct an acoustic model that includes multiple rooms and audio devices; Input the spatial layout information of each room and the physical location information of each audio device into the acoustic simulation software; based on the performance parameters of each audio device, configure the corresponding performance parameters for each audio device in the acoustic simulation software; perform simulation calculations according to the acoustic simulation software to construct an acoustic model that includes multiple rooms and audio devices.

[0050] Input the room layout information and the location information of the audio device into the acoustic simulation software, and use the performance parameters of each audio device to configure the parameters of each audio device. The software will perform simulation calculations based on this information using acoustic algorithms and physical models. These algorithms and models consider characteristics such as the speed of sound propagation in air, attenuation coefficient, reflection, and diffraction in the air, as well as the impact of obstacles in the room on sound propagation. Through simulation calculations, an acoustic model that includes multiple rooms and audio devices is generated.

[0051] 203. Based on the acoustic model, calculate the acoustic coupling coefficient between different rooms, and analyze the acoustic coupling relationship between different rooms based on the acoustic coupling coefficient between different rooms; In the acoustic model, define the positions of the sound source and the receiving point, as well as the sound propagation path; simulate the process of sound starting from the sound source, passing through the propagation paths between different rooms, and reaching the receiving point; calculate the acoustic coupling coefficient between different rooms according to the simulation results; analyze the acoustic coupling relationship between different rooms based on the acoustic coupling coefficient between different rooms.

[0052] Use the graphical interface or scripting language in the acoustic simulation software to define the positions of the sound source and the receiving point in the acoustic model. The sound source can be a speaker, musical instrument, or other object that can generate sound, while the receiving point is usually a microphone, listener, or other position that needs to receive sound. When defining these positions, consider the geometric shape of the room, the distribution of obstacles, and the physical positions of audio devices to ensure the accuracy of the simulation results.

[0053] Based on the positions of the sound source and the receiving point, as well as the obstacle information in the room, use acoustic algorithms and physical models to simulate the sound propagation path. These algorithms and models consider the characteristics of sound propagation in the air, such as the propagation speed, attenuation coefficient, reflection, diffraction, etc., as well as the influence of obstacles such as walls and furniture in the room on sound propagation; through simulation calculations, the process of sound starting from the sound source, passing through the propagation paths between different rooms, and finally reaching the receiving point can be generated.

[0054] Obtain the sound pressure level or sound intensity level data of the sound source and the receiving point at different frequencies through the acoustic simulation software. These data constitute the frequency response function. Then, use statistical analysis methods, such as correlation analysis or coherence analysis, to calculate the similarity or correlation of the frequency response functions between different rooms, so as to quantify the degree of acoustic coupling. Finally, according to the calculation results of the similarity or correlation, the acoustic coupling coefficient between different rooms can be obtained. This acoustic coupling coefficient reflects the efficiency and effect of sound propagation from one room to another. The acoustic coupling coefficient can not only help understand the degree of acoustic coupling between different rooms, but also provide an important reference basis for subsequent audio system optimization and configuration. For example, when the acoustic coupling coefficient between two rooms is high, it means that the acoustic interaction between them is strong and sound is easy to propagate from one room to another. In this case, some measures can be taken to reduce acoustic coupling, such as adding sound insulation materials, adjusting the room layout, or optimizing the configuration of audio devices, etc.; on the contrary, when the acoustic coupling coefficient is low, it means that the acoustic interaction between them is weak and the sound propagation efficiency is low. In this case, some measures may be needed to enhance the acoustic coupling to improve the sound transmission efficiency and quality.

[0055] 204. Based on the acoustic model, simulate the response of each audio device to a preset audio signal to be measured to analyze the signal transmission characteristics of each audio device; In an acoustic model, a preset audio signal to be measured is input into each audio device, and the output signals of each audio device are extracted; the output signals of each audio device are compared with the audio signal to be measured, and the parameter changes during signal transmission are analyzed; based on the analysis results, the signal transmission characteristics of each audio device are obtained.

[0056] In an acoustic model, a preset audio signal to be measured is input into each audio device. After each audio device receives the audio signal to be measured, the output signals of each audio device are extracted. These output signals are the responses of the audio devices to the input signal and contain various characteristics of the audio devices when processing sound. These characteristics include, but are not limited to, frequency response, phase response, and distortion degree.

[0057] After the output signals of each audio device are extracted, they are compared and analyzed with the original audio signal to be measured. This process usually involves two aspects: time-domain analysis and frequency-domain analysis. In time-domain analysis, the differences between the output signal and the input signal in terms of waveform, amplitude, and phase are observed; in frequency-domain analysis, mathematical tools such as Fourier transform are used to convert the signal from the time domain to the frequency domain, so as to more intuitively analyze the gain, attenuation, and phase changes of the signal at different frequencies. Through comparative analysis, the parameter changes during signal transmission can be quantified, such as gain change, phase shift, distortion degree, etc. These parameter changes reflect the performance of the audio device during signal transmission, including its amplification, attenuation, phase adjustment of the sound signal, and possible introduced noise and distortion, etc.; based on the analysis results, the signal transmission characteristics of each audio device can be obtained.

[0058] In addition, in order to more deeply understand the signal transmission characteristics of audio devices, methods such as signal quality assessment algorithms, nonlinear distortion analysis, and dynamic range testing can also be adopted. These methods can provide more detailed and accurate audio device performance assessment results.

[0059] 205. Integrate the analysis results of the acoustic coupling relationship between different rooms and the signal transmission characteristics of each audio device to obtain an acoustic characteristic parameter set; Integrate the analysis results of the acoustic coupling relationship and the audio device signal transmission characteristics obtained in steps 203 and 204 to form a complete acoustic characteristic parameter set. This acoustic characteristic parameter set contains information about the acoustic characteristics of each room, the sound propagation ability between different rooms, as well as the processing ability and fidelity of each audio device to the input signal.

[0060] 206. According to the acoustic characteristic parameter set, optimize the channel allocation and volume adjustment of each audio device to obtain an optimized audio configuration parameter set; 207. According to the optimized audio configuration parameter set, automatically configure the channel allocation, volume adjustment, and audio signal transmission path of the multi-room audio system; Generate a configuration file for the audio system according to the optimized audio configuration parameter set; import the configuration file into the control software, and automatically configure the channel allocation, volume adjustment, and audio signal transmission path of the audio system according to the content of the configuration file.

[0061] According to the optimized audio configuration parameter set, use a configuration generation algorithm and tool to generate a configuration file for the audio system. This file adopts a standardized format and details the parameter settings of each audio device in the audio system, including but not limited to channel allocation, volume adjustment, audio signal transmission path, audio device type, and their connection relationships; after the configuration file is generated, it is imported into the control software of the audio system through a dedicated interface or import function.

[0062] During the configuration process, real-time parameter verification and conflict detection are also carried out to ensure that all settings are legal and effective, and to avoid abnormalities or performance degradation of the audio system caused by configuration errors; once the configuration is completed, the audio system can operate according to the preset parameters to achieve efficient and stable audio signal transmission and processing.

[0064] Collect the feedback data of users when using the audio system. The feedback data includes but not limited to the satisfaction evaluation of users on volume, sound quality, channel allocation, and audio signal transmission path; monitor the behavior patterns of users in a multi-room environment. The behavior patterns include the movement paths, stay times between rooms of users, and the types of audio activities carried out in different rooms; according to the collected user feedback data and the monitored behavior patterns, analyze the audio preferences and habits of users, including the audio needs, preferred volume levels, sound quality preferences, and channel allocation preferences of users in different scenarios; based on the analysis results, adjust the user preference data to optimize the configuration of the audio system to make it more in line with the personalized needs of users; apply the adjusted user preference data to the control software of the audio system to automatically adjust the parameter settings of the audio system and achieve the personalized optimization of the audio system.

[0065] In the embodiments of the present invention, by obtaining the room layout and audio device information, constructing an acoustic model and analyzing the acoustic coupling relationship and signal transmission characteristics, an acoustic characteristic parameter set is obtained, and based on this, the audio configuration is intelligently optimized to achieve the automatic and accurate configuration of the multi-room audio system, significantly improving the sound quality, avoiding uneven sound quality and sound interference, and bringing a better auditory experience to users.

[0066] Please refer to Figure 3 , another embodiment of the configuration method of the multi-room audio system in the embodiments of the present invention includes: 301. Obtain the spatial layout information of each room, the physical location information and performance parameters of each audio device; 302. Based on the spatial layout information of each room, the physical location information and performance parameters of each audio device, construct an acoustic model including multiple rooms and audio devices; 303. Analyze the acoustic coupling relationship between different rooms and the signal transmission characteristics of each audio device based on the acoustic model to obtain an acoustic characteristic parameter set; 304. Analyze the acoustic coupling strength between rooms in the acoustic characteristic parameter set and adjust the room pairs that need to reduce or enhance acoustic coupling; For room pairs with too high coupling strength, this usually means that excessive reflections and interferences will occur when audio signals propagate between the two rooms, resulting in a decline in sound quality. To solve this problem, a series of measures can be taken to reduce acoustic coupling, such as adding sound insulation materials, adjusting the room layout, or changing the placement position of audio devices. On the other hand, for room pairs with too low coupling strength, measures can be taken to enhance acoustic coupling to ensure that audio signals can propagate smoothly between different rooms, which can be achieved by adding acoustic waveguides, adjusting the acoustic environment in the room, or optimizing the configuration of audio devices.

[0067] 305. Adjust the channel allocation of relevant audio devices based on the signal transmission characteristics of each audio device; Identify the optimal operating frequency range of each audio device, and allocate the most suitable channel content to each audio device according to the optimal operating frequency range of each audio device; Optimize the channel allocation of each audio device according to the relative relationship between the physical location information of each audio device and the listener's position.

[0068] Among them, optimizing the channel allocation of each audio device according to the relative relationship between the physical location of each audio device and the listener's position includes: using three-dimensional space positioning technology to determine the precise positions of each audio device and the listener; calculating the transmission path of the audio signal to the listener and possible reflections and interferences according to the straight-line distance, relative angle between each audio device and the listener, and the distribution of obstacles in the room; predicting the audio signal quality received by the listener under different channel allocation schemes through acoustic field simulation software; selecting the channel allocation scheme that enables the listener to receive the optimal audio signal quality.

[0069] Identify and record the optimal operating frequency range of each audio device by means of testing or querying the device specification sheet. This range represents the frequency interval within which the audio device can most effectively generate and / or reproduce audio signals. Allocate the channel content to each audio device according to the optimal operating frequency range of each audio device. This allocation process aims to ensure that each audio device is responsible for processing the audio content within the frequency range where it performs best and has the least distortion. Specifically, different frequency bands or channels of the audio signal are allocated to the audio device that performs best in that band or channel, thereby optimizing the performance of the overall audio system.

[0070] Utilize three-dimensional space positioning technologies, such as lidar, ultrasonic ranging, or infrared positioning, etc., to determine the specific positions of each audio device and the listener in three-dimensional space. These technologies can provide positioning accuracy at the centimeter or even millimeter level to ensure an accurate understanding of the relative position relationship between the device and the listener. Based on the position information between the device and the listener, combined with the layout and obstacle distribution in the room, use acoustic principles and software tools to calculate the transmission path of the audio signal from each audio device to the listener, including considering the straight-line distance, relative angle between the audio device and the listener, and complex acoustic phenomena such as reflection, refraction, and interference that the signal may encounter during transmission. To more accurately simulate these phenomena, factors such as the size, shape of the room, the position and material of the wall materials, and furniture and other obstacles also need to be considered.

[0071] After obtaining the transmission path information of the audio signal, use sound field simulation software to predict the audio signal quality received by the listener under different channel allocation schemes. The sound field simulation software can simulate the propagation process of the audio signal in the room based on acoustic principles and transmission path information, and calculate key parameters such as the signal strength, frequency response, and phase relationship received by the listener at different positions. By comparing the simulation results under different channel allocation schemes, the impact of each scheme on the listener's auditory experience can be evaluated. According to the results of the sound field simulation software, select the channel allocation scheme that enables the listener to receive the optimal audio signal quality. This process not only considers the performance characteristics and position relationship of the audio devices, but also fully considers the acoustic environment in the room and the listener's auditory needs. By implementing this scheme, it can be ensured that the multi-room audio system can provide a clear, balanced, and immersive audio experience in various scenarios.

[0072] 306. Adjust the volume of each audio device according to the acoustic characteristics of each room and user preferences. According to the acoustic characteristics of each room, apply an acoustic compensation algorithm to calculate the volume compensation amount of each audio device. Obtain user volume preference information, and combine the user preference information and the acoustic compensation result to adjust the volume of each audio device.

[0073] Applying an acoustic compensation algorithm can calculate the corresponding volume compensation amount for the audio signal attenuation and distortion experienced by each audio device at a specific location in the room. During the calculation process, the algorithm comprehensively considers the characteristics of the audio signal such as frequency, amplitude, and phase, as well as the acoustic parameters of the room to ensure the accuracy and effectiveness of the compensation.

[0074] On the one hand, through user surveys, understand users' subjective feelings and requirements for volume, including volume requirements in different scenarios, requirements for sound quality, etc.; on the other hand, use an intelligent learning system to monitor and analyze users' usage habits in real time to obtain more objective and accurate user preference information. This information includes users' volume adjustment habits at different times and in different emotional states, as well as users' preference characteristics for audio signals.

[0075] After obtaining the acoustic compensation results and user preference information, make personalized and fine adjustments to each parameter of the audio device. This adjustment process not only considers the physical impact of the room on the audio signal but also fully considers the personalized auditory needs of users. According to the acoustic compensation results and user preference information, automatically adjust parameters such as the volume, frequency response, and phase of the audio device to ensure that the audio signal remains clear, balanced, and in line with user preferences during transmission.

[0076] By constructing an acoustic model that includes multiple rooms and audio devices and analyzing the acoustic coupling relationship between different rooms and the signal transmission characteristics of each audio device based on this model, detailed acoustic characteristic parameters such as room reverberation and sound wave propagation paths can be obtained. Combining information such as the spatial layout of the room, the physical location of the audio device, and the distribution of obstacles in the room, the distance attenuation coefficient from the audio device to the listener can be calculated, which reflects the degree of attenuation of the audio signal with distance. At the same time, using parameters such as reverberation time, the room reverberation coefficient of each room can be calculated, which describes the characteristics of sound wave reflection and attenuation in the room. In addition, by actually measuring or simulating and analyzing the background noise level in the room, the environmental noise coefficient of each room can be obtained.

[0077] Based on the reference volume, the compensated volume of the audio device is calculated using the distance attenuation coefficient from the audio device to the listener, the room reverberation coefficient, the ambient noise coefficient, and a preset weight compensation coefficient. The weight compensation coefficient includes a distance compensation weight coefficient, a reverberation compensation weight coefficient, and a noise suppression coefficient. The volume compensation calculation formula is: Vi = V0 × (1 + α × Di) × (1 + β × Ri) × (1 - γ × Ni), where Vi is the compensated volume of the i-th audio device, V0 is the reference volume, Di is the distance attenuation coefficient of the i-th audio device to the listener (0 - 1), Ri is the room reverberation coefficient of the i-th room (0 - 1), Ni is the ambient noise coefficient of the i-th room (0 - 1), α is the distance compensation weight coefficient, β is the reverberation compensation weight coefficient, and γ is the noise suppression coefficient.

[0078] For example, in a living room scenario, there are 3 audio devices, and the reference volume V0 is set to 60 decibels. For one of the audio devices, device A, its distance attenuation coefficient DA is 0.3 (indicating that the device is relatively close to the listener), the room reverberation coefficient RA is 0.2 (indicating that the device is located in a corner), and the ambient noise coefficient NA is 0.1 (indicating that the environment is relatively quiet). Additionally, the distance compensation weight coefficient α = 0.8, the reverberation compensation weight coefficient β = 0.6, and the noise suppression coefficient γ = 0.5. Substituting the above relevant parameters into the formula VA = 60 × (1 + 0.8×0.3) × (1 + 0.6×0.2) × (1 - 0.5×0.1), the actual output volume VA of audio device A is calculated to be 79.3 decibels. This method can dynamically adjust the volume of each audio device according to the actual environment, thereby optimizing the user's listening experience.

[0079] After obtaining the set of acoustic characteristic parameters through acoustic model analysis, professional acoustic measurement and analysis software, such as acoustic simulation software EASE, ODEON, etc., can be used to combine with the set of acoustic characteristic parameters to simulate the propagation process of sound waves in the room. Through simulation calculations, parameters such as the reverberation time and early decay time of each room can be directly extracted. At the same time, by using technical means such as impulse response analysis, parameters such as clarity and speech intelligibility can be further calculated.

[0080] Calculate the acoustic scores of each room by using the reverberation time, early decay time, clarity, speech intelligibility of each room, and the weight coefficients of each relevant parameter preset. The formula for calculating the acoustic score is: ASi = w1×RT60i + w2×EDTi + w3×C80i + w4×D50i, where ASi is the acoustic score of the i-th room, RT60i is the reverberation time (s), EDTi is the early decay time (s), C80i is the clarity (dB), D50i is the speech intelligibility, and w1~w4 are the weight coefficients of each relevant parameter, corresponding to the reverberation time, early decay time, clarity, and speech intelligibility respectively. Determine the excellent or poor degree of the acoustic effect of each room according to the acoustic scores of each room. For example, in a living room where RT60 is measured as 0.8 s, EDT is 0.7 s, C80 is 6 dB, and D50 is 0.65, substituting into the formula to calculate the acoustic score AS as 1.78, indicating that the acoustic effect of this room is good (such as the score range is 0 - 2, >1.5 is excellent). This algorithm not only considers the coupling effect of multiple acoustic parameters, is more accurate than simple distance attenuation compensation, but also the parameters are adjustable, facilitating optimization for different scenarios. In addition, this algorithm reduces the difficulty of manual debugging, improves the automation level of the system, enables the system to automatically optimize the audio settings according to the scoring results, and thus enhances the user's acoustic experience.

[0081] Determine the adjustment amount of the volume of each room according to the excellent or poor degree of the acoustic effect, and calculate the target volume of each audio device based on the volume of each audio device after compensation, the adjustment amount, and the user preference information, so as to adjust the volume of each audio device.

[0082] In the formula for calculating the acoustic score, clarity and speech clarity are two different acoustic parameters, which respectively reflect different characteristics of the sound signal. Clarity usually refers to the proportional relationship between the early reflected sound and the late reverberant sound in the sound signal, and it measures the overall intelligibility or recognizability of the sound signal. Speech clarity, on the other hand, focuses more on the degree of human ear's identification of language information in an environment with noise interference, and it particularly focuses on the intelligibility of the speech signal.

[0083] 307. Integrate the adjustment results of each parameter to obtain an optimized set of audio configuration parameters; Comprehensively integrate and analyze the calculated acoustic compensation amount, the adjusted value of the user's volume preference, and the possible adjustment of the parameters of the audio device itself, such as equalizer settings, delay adjustment, etc. Through audio processing algorithms and intelligent optimization technologies, fuse these scattered parameter adjustment results into a coordinated and optimized set of audio configuration parameters.

[0084] 308. According to the optimized set of audio configuration parameters, automatically configure the channel allocation, volume adjustment, and audio signal transmission path of the multi-room audio system.

[0085] In the embodiments of the present invention, by comprehensively considering the room layout, audio device information, and user preferences, an acoustic model is constructed and the acoustic coupling and signal transmission characteristics are analyzed, and the channel allocation, volume, and acoustic coupling strength are adjusted, so as to achieve accurate configuration of each audio device in the multi-room audio system, significantly improve the sound effect balance and clarity, and meet the personalized auditory needs of users.
