Description
Technical Field
[0001] This invention relates to the field of audio system technology, and in particular to an audio stereo effect management system and method based on immersive sound effects. Background Technology
[0002] With the technological advancements in audio systems, users have higher demands for intelligent audio systems. To ensure the optimal sound quality of an audio system in actual operation, acoustic testing is typically conducted, followed by adjustments to optimize music playback.
[0003] Patent publication number CN114650494A discloses a DSP audio system and an automatic acoustic testing method for the audio system. The method includes: a DSP digital signal processing module for testing digital audio signals and generating test results; an MCU control module outputting control signals based on the test results to control the audio system to adjust parameters; a digital-to-analog converter module for converting the digital audio signals back into analog audio signals; a power amplifier module for amplifying the analog audio signals; and a speaker module playing sound when it receives the analog audio signals. However, this DSP audio system and automatic acoustic testing method only adjust parameters based on test results before the system operates. After operation, it cannot correct parameters based on environmental factors. Furthermore, it can easily create a "sweet spot," affecting the experience of listeners in other areas, and the sound quality deteriorates as the system continues to operate. Summary of the Invention
[0004] The purpose of this invention is to provide a stereo sound management system and method based on immersive sound effects, in order to solve the problems of existing technology, which only adjusts parameters based on test results before the sound system is in operation, and cannot correct the parameters according to the influence of the environment during operation after the sound system is in operation. In addition, it is easy to form a "sweet spot" during use, which affects the experience of listeners in other areas, and the realism is low as the sound system continues to operate.
[0005] This invention provides a stereo sound effect management system based on immersive sound effects, comprising:
[0006] The detection module is used to detect ambient temperature and humidity, venue parameters, and sound pressure.
[0007] A storage module, connected to the detection module, is used to store the ambient temperature and humidity measured by the detection module and the corresponding propagation loss;
[0008] An analysis module, which is connected to the detection module and the storage module respectively, is used to establish a relationship model based on historical environmental temperature and humidity, and determine the sound field parameters according to actual needs. In response to determining the sound field parameters, the analysis module inputs the current environmental temperature and humidity into the relationship model to obtain the propagation loss, calculates the propagation speed based on the current environmental temperature and humidity, and determines the sound arrangement based on the venue parameters, propagation loss, propagation speed and sound field parameters.
[0009] In response to the speakers being arranged and starting to operate, the analysis module obtains the actual sound pressure of the venue and compares it with the preset standard. In response to the sound pressure not meeting the requirements, the gain parameters of the speakers corresponding to the areas where the sound pressure does not meet the requirements are adjusted according to the sound pressure, or the propagation speed is updated, and the delay and gain parameters of each speaker are corrected according to the updated propagation speed.
[0010] Wherein: the propagation loss is the amount of sound pressure loss per meter of sound propagation in the air.
[0011] As a preferred technical solution for a stereo sound management system based on immersive sound effects, the relationship model is established based on the relationship between ambient temperature and humidity and propagation loss. If the ambient temperature and humidity are input, the propagation loss is output.
[0012] As a preferred technical solution for a stereo sound management system based on immersive sound effects, the analysis module determines the speaker arrangement based on venue parameters, propagation loss, propagation speed, and sound field parameters, including:
[0013] Obtain the venue parameters and establish a three-dimensional coordinate system for the venue with the center of the venue as the origin;
[0014] The propagation loss and propagation speed are obtained based on the ambient temperature and humidity.
[0015] Obtain the candidate speaker installation locations and the number of speakers within the venue;
[0016] The speaker layout, installation location, and installation angle are determined based on the venue parameters, propagation loss, propagation speed, and sound field parameters.
[0017] As a preferred technical solution for a stereo sound management system based on immersive sound effects, the analysis module acquires the actual sound pressure of the venue and compares it with a preset standard. In response to the actual sound pressure at each location in the venue meeting the preset standard, the operating parameters of the sound system are maintained and the actual sound pressure at each location in the venue is periodically detected.
[0018] If the actual sound pressure at various locations in the venue does not meet the preset standard, the corresponding processing method is determined based on the area of the region where the sound pressure does not meet the preset standard.
[0019] As a preferred technical solution for a stereo sound management system based on immersive sound effects, the analysis module determines the corresponding processing method based on the area of the region that does not meet the preset standard. In response to the area of the region that does not meet the requirements being smaller than the preset area, the gain parameters of the speaker corresponding to the region that does not meet the requirements are adjusted according to the sound pressure.
[0020] In response to the area of the non-compliant area being greater than or equal to the preset area, the analysis module re-acquires the ambient temperature and humidity of the venue, updates the propagation speed and propagation loss based on the re-acquired ambient temperature and humidity, and then corrects the delay and gain parameters of each speaker.
[0021] As a preferred technical solution for a stereo sound management system based on immersive sound effects, the analysis module records the difference between the sound pressure and the corresponding preset standard as the standard deviation value according to the gain parameter of the speaker corresponding to the area where the sound pressure adjustment does not meet the requirements, and the adjustment range of the gain parameter is positively correlated with the standard deviation value.
[0022] As a preferred technical solution for a stereo sound management system based on immersive sound effects, in response to correcting the delay of each speaker, the analysis module takes the center of the venue as the origin, calculates the distance of each speaker to the origin, calculates the propagation time of the sound of each speaker to the origin based on the updated propagation speed and distance, and applies delay compensation to the audio signal of each speaker based on the propagation time.
[0023] As a preferred technical solution for a stereo sound management system based on immersive sound effects, in response to correcting the gain parameters of each speaker, the analysis module inputs the current ambient temperature and humidity into the relational model to obtain the current propagation loss, and adjusts the gain parameters of each speaker according to the current propagation loss.
[0024] As a preferred technical solution for an immersive sound effect-based stereo sound management system, the venue parameters include: space dimensions, sound absorption coefficient of wall or floor materials, and obstacle coordinates.
[0025] This invention also provides a method for managing stereo sound effects based on immersive sound effects, including:
[0026] A relationship model is established based on historical environmental temperature and humidity and the corresponding propagation loss;
[0027] Determine the sound field parameters according to actual needs;
[0028] Detect the current ambient temperature and humidity, and calculate the speed of sound propagation;
[0029] The current ambient temperature and humidity are input into the relational model to obtain the sound propagation loss;
[0030] The speaker arrangement is determined based on the sound propagation loss, sound propagation speed, and sound field parameters.
[0031] After the sound system starts operating, it acquires the actual sound pressure in each area of the venue and compares it with the corresponding preset standards. In response to areas that do not meet the preset standards, it adjusts the gain parameters of the speakers in the areas that do not meet the requirements based on the sound pressure, or updates the propagation speed. Based on the updated propagation speed, it corrects the delay and gain parameters of each speaker until the sound pressure in each area meets the requirements.
[0032] Compared with existing technologies, the beneficial effects of this invention are that by acquiring temperature, humidity, venue parameters, and sound pressure data in real time, it can accurately calculate the sound propagation loss under different environments through a relational model, and dynamically adjust the audio delay and gain parameters by combining the formulas on the influence of temperature and humidity on sound speed. This allows the audio system to automatically adapt to changes in the venue environment, such as temperature fluctuations caused by air conditioning operation and humidity changes caused by the gathering of people. It effectively avoids problems such as asynchronous sound delay and unbalanced sound pressure caused by environmental factors, ensuring that sound is clearly transmitted from the correct direction and at an appropriate volume. This enhances the accuracy of sound positioning and the spatial layering of sound effects, making users feel as if they are in a real scene, thereby enhancing the realism of immersive sound effects.

[0034] Figure 2 This is a flowchart illustrating the steps of a stereo sound effect management method based on immersive sound effects, as described in an embodiment of the present invention. Detailed Implementation
[0035] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.
[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.
[0037] Please see Figure 1 As shown, it is a structural block diagram of the stereo sound management system based on immersive sound effects according to an embodiment of the present invention, including:
[0038] The detection module is used to detect ambient temperature and humidity, venue parameters, and sound pressure.
[0039] The storage module, which is connected to the detection module, is used to store the ambient temperature and humidity measured by the detection module and the corresponding propagation loss.
[0040] The analysis module, which is connected to the detection module and the storage module respectively, is used to establish a relationship model based on historical environmental temperature and humidity, and determine the sound field parameters according to actual needs. In response to the determination of the sound field parameters, the analysis module inputs the current environmental temperature and humidity into the relationship model to obtain the propagation loss, calculates the propagation speed based on the current environmental temperature and humidity, and determines the sound arrangement based on the venue parameters, propagation loss, propagation speed and sound field parameters.
[0041] Once the speakers are arranged and running, the analysis module obtains the actual sound pressure level of the venue and compares it with the preset standard. If the sound pressure level does not meet the requirements, the gain parameters of the speakers in the area with the unacceptable sound pressure level are adjusted or the propagation speed is updated. Based on the updated propagation speed, the delay and gain parameters of each speaker are corrected.
[0042] Wherein: propagation loss is the amount of sound pressure lost per meter of sound propagation in the air.
[0043] In detail, in this embodiment of the invention, the detection module uses a high-precision temperature and humidity sensor (accuracy ±0.5℃, ±2%RH) to collect ambient temperature and humidity, and a distributed microphone array (≥8 measurement points) and acoustic camera to collect sound pressure distribution and sound pressure. Venue parameters include: space dimensions, sound absorption coefficient of wall or floor materials (sound absorption coefficient can be determined by querying the sound absorption levels of different materials in the venue through big data analysis and based on the sound absorption levels, or obtained through direct detection), and obstacle coordinates. Sound field parameters include target sound pressure, uniformity, and other parameters related to the sound field distribution in the venue.
[0044] Specifically, on the one hand, the embodiments of the present invention, through the joint detection of multiple sensors, can accurately detect ambient temperature, humidity, and sound pressure, providing an accurate data foundation for subsequent analysis and adjustment. Simultaneously, by using a relational model, it can more accurately predict sound propagation loss, improving the optimization accuracy of the speaker arrangement scheme, thereby achieving a more ideal sound field effect. On the other hand, when sound pressure changes, precise gain and delay adjustments ensure that the sound pressure in each area of the venue meets the preset standard under different environmental conditions, thus greatly enhancing the realism of the immersive sound effect.
[0045] Furthermore, the relational model is established based on the relationship between ambient temperature and humidity and propagation loss. If ambient temperature and humidity are input, then propagation loss is output.
[0046] In detail, in this embodiment of the invention, the construction of the relational model includes: collecting sound propagation loss data of the venue under a large amount of different environmental temperature and humidity conditions before setting up the venue, forming a rich training dataset. A neural network model is constructed using a deep learning framework. The input layer of this model is the environmental temperature and humidity parameters, and the output layer is the corresponding propagation loss value. Through multiple iterations of training on the training dataset, the weights and biases of the neural network are optimized until the fit between the output result and the actual propagation loss value is greater than a preset standard. In implementation, the specific requirements for the fit are determined by the model type and evaluation indicators. For core data, the fit between the model's output result and the actual data is typically required to be ≥0.95. Preferably, the preset standard is 0.95. In practical applications, the current environmental temperature and humidity are input into the trained relational model to quickly obtain the corresponding propagation loss value. The data collection, processing, and training processes of the model are all existing technologies and will not be elaborated upon here.
[0047] Specifically, the relational model constructed by the method according to the embodiments of the present invention can adapt to various complex environmental conditions. Through training with deep learning algorithms, the model can automatically learn the nonlinear relationship between environmental temperature and humidity and propagation loss. Compared with traditional empirical formulas or simple models, it has higher accuracy and adaptability, thereby further improving the realism of immersive sound effects.
[0048] Furthermore, the analysis module determines the speaker arrangement based on venue parameters, propagation loss, propagation speed, and sound field parameters, including:
[0049] Obtain the venue parameters and establish a three-dimensional coordinate system for the venue with the center of the venue as the origin;
[0050] The propagation loss and propagation speed are obtained based on the ambient temperature and humidity.
[0051] Obtain the candidate speaker installation locations and the number of speakers within the venue;
[0052] The speaker layout, installation position, and installation angle are determined based on the venue parameters, propagation loss, propagation speed, and sound field parameters, so that the sound field formed by the speakers can meet the sound field parameters.
[0053] In implementation, propagation loss and propagation speed are calculated based on ambient temperature and humidity, and combined with the three-dimensional structural information of the venue to determine candidate installation locations for the speakers. Considering various possible installation methods, candidate locations are distributed across different areas of the venue, including walls, ceilings, and floors. Detailed sound field simulation analysis is performed on each candidate installation location using acoustic simulation software (such as EASE). During the simulation, the propagation path of the sound is obtained by simulating reflection, absorption, and obstruction during sound propagation, taking into account venue parameters. Based on the sound propagation path, propagation loss is incorporated into the sound field simulation analysis; that is, the gradual attenuation of sound pressure as the sound travels along the propagation path. After determining the propagation path, the sound propagation time can be determined using a three-dimensional coordinate system, thus obtaining the final simulated sound field to evaluate the sound field distribution under different installation locations and angles. By continuously iterating calculations, the optimal combination of installation position and angle that meets the requirements of sound field parameters is found. Existing technologies use optimization algorithms (such as particle swarm optimization) to optimize the installation position and angle of the speakers, which can realize the relevant content of determining the speaker arrangement in the embodiments of this invention. This process is existing technology and will not be described in detail here.
[0054] In detail, by optimizing the arrangement of the speakers, a uniform sound field distribution can be achieved within the venue, reducing sound pressure deviation and allowing listeners to experience consistent sound effects from different positions, thereby further enhancing the realism of the immersive sound effects.
[0055] Furthermore, the analysis module acquires the actual sound pressure level of the venue and compares it with a preset standard. In response to the actual sound pressure level at each location in the venue meeting the preset standard, the operating parameters of the sound system are maintained and the actual sound pressure level at each location in the venue is periodically detected.
[0056] If the actual sound pressure at various locations in the venue does not meet the preset standard, the corresponding processing method is determined based on the area of the region where the sound pressure does not meet the preset standard.
[0057] Furthermore, in actual operation, the required sound pressure levels differ in different areas of the venue. For example, in a conference setting, the sound pressure level in the main listening area may need to reach 80-90 dB with a uniformity deviation of no more than ±3 dB, while the sound pressure level in other areas only needs to reach 75-95 dB with a uniformity deviation of no more than ±3 dB. Preferably, the sound pressure level in the main listening area is 80-85 dB with a uniformity deviation of no more than ±5 dB, and the sound pressure level in other areas is 75-80 dB with a uniformity deviation of no more than ±3 dB.
[0058] Specifically, this embodiment of the invention divides the area and sets sound pressure detection points to monitor the sound pressure distribution in the venue and compares it with preset standards. If there are areas that do not meet the preset standards, the system judges the situation based on the area of the non-compliant area. The non-compliance is divided into two situations: one is caused by changes in the sound propagation speed and propagation loss due to changes in ambient temperature and humidity, and the other is caused by the operating parameters of a single speaker not meeting the current environment. This allows the system to make more targeted adjustments, thereby further improving the realism of the immersive sound effect.
[0059] Furthermore, the analysis module determines the corresponding processing method based on the area of the region that does not meet the preset standard. In response to the region that does not meet the requirements having an area smaller than the preset area, the gain parameter of the speaker corresponding to the region that does not meet the requirements is adjusted according to the sound pressure.
[0060] In response to the area of the non-compliant area being greater than or equal to the preset area, the analysis module re-acquires the ambient temperature and humidity of the venue. Based on the re-acquired ambient temperature and humidity, it updates the propagation speed and propagation loss, and then corrects the delay and gain parameters of each speaker.
[0061] The preset area threshold is selected based on the venue area and actual conditions. Preferably, the preset area threshold is configured as follows: 10% for venue area less than or equal to 100 square meters, and 15% for venue area greater than 100 square meters.
[0062] Furthermore, the analysis module, based on the gain parameters of the speakers corresponding to the areas where the sound pressure adjustment does not meet the requirements, records the difference between the sound pressure and the corresponding preset standard as the standard deviation. The adjustment range of the gain parameter is positively correlated with the standard deviation; that is, a positive standard deviation increases the gain coefficient, and the larger the standard deviation, the greater the increase; a negative standard deviation decreases the gain coefficient, and the smaller the standard deviation, the smaller the decrease. This embodiment of the invention provides a method for adjusting the gain parameter:
[0063] In response to a standard deviation value being greater than or equal to a preset standard deviation, the first adjustment coefficient is selected to adjust the gain parameter;
[0064] In response to a positive standard deviation value that is less than the preset standard deviation value, a second adjustment coefficient is selected to adjust the gain coefficient.
[0065] In detail, during actual operation, the adjustment range of the gain coefficient should not be too large, as this will lead to audio distortion and other problems. Therefore, there is a range for the selection of the gain coefficient. Depending on the actual situation, the range of the gain coefficient should be between 1.0 and 1.25. Preferably, the first adjustment coefficient is 1.20 and the second adjustment coefficient is 1.10. The preset standard deviation is the average of the historical standard deviation values.
[0066] In detail, in response to correcting the delay of each speaker, the analysis module calculates the distance from each speaker to the origin, using the center of the venue as the origin. Based on the updated propagation speed and distance, it calculates the propagation time of the sound from each speaker to the origin, and applies delay compensation to the audio signal of each speaker based on the propagation time. The propagation speed can be approximated through calculation or directly obtained using a detector. For example, a sound speed calculator can output the speed of sound propagation in the air by inputting ambient temperature, humidity, and air pressure. Therefore, the process of calculating or obtaining the speed of sound propagation is existing technology and will not be elaborated upon here.
[0067] For a single speaker, the time difference between it and the speaker with the longest propagation time is calculated. For example, if the propagation time of speaker A is 10ms and the propagation time of speaker B with the longest propagation time is 15ms, then the time difference between speaker A and speaker B is 5ms. A delay compensation is applied to the audio signal of this speaker using a digital signal processor (DSP) to minimize the time difference between the sounds of all speakers arriving at the reference point. For example, for speaker A, its audio signal is delayed by 5ms using a DSP, making the time difference between the sounds of all speakers arriving at the origin as small as possible (e.g., less than 1ms), thereby achieving synchronized sound arrival.
[0068] In detail, this invention, through precise distance measurement and time calculation, as well as the high-precision delay compensation function of the DSP, ensures that the delay adjustment accurately reflects the actual situation of sound propagation, thereby improving the accuracy and reliability of the system. By optimizing the synchronization of sound, listeners can more clearly perceive changes in the direction and position of sound, thus significantly enhancing the realism and immersion of the immersive sound effects, bringing users a higher quality auditory experience, and further improving the realism of the immersive sound effects.
[0069] In detail, in response to correcting the gain parameters of each speaker, the analysis module inputs the current ambient temperature and humidity into the relationship model to obtain the current propagation loss, and adjusts the gain parameters of each speaker according to the current propagation loss.
[0070] In detail, the venue parameters include: space dimensions, sound absorption coefficient of wall or floor materials, and coordinates of obstacles.
[0071] The current ambient temperature and humidity (including temperature and humidity) are input into the relational model to obtain the propagation loss values for each frequency band. The current propagation loss value is compared with the propagation loss value at the previous moment to calculate the loss difference for each frequency band. For example, if the updated propagation loss for the current high-frequency band (8kHz-20kHz) is 3dB / m, and the previous propagation loss was 2dB / m, then the loss difference for that frequency band is 1dB / m. Since the corresponding distances can be determined during the speaker arrangement process, the amount of increase in sound pressure required can be determined, and the gain parameters can be adjusted to achieve the corresponding increase in sound pressure. In implementation, a digital signal processor (DSP) can be used to adjust the gain parameters of each speaker in the corresponding frequency band to compensate for the sound pressure changes caused by changes in propagation loss.
[0072] Specifically, the clear proportional relationship and precise calculation method enable the gain adjustment to accurately reflect the changes in propagation loss, improve the system's adaptability and adjustment accuracy, and avoid sound distortion or other problems caused by improper gain adjustment. This effectively improves the clarity and layering of the sound, allowing listeners to hear the sound details of each frequency band more clearly, thereby further enhancing the realism of the immersive sound effect.

[0079] Step S6: After the sound system starts running, the actual sound pressure in each area of the venue is acquired and compared with the corresponding preset standard. In response to areas that do not meet the preset standard, the gain parameters of the speakers in the areas that do not meet the requirements are adjusted according to the sound pressure, or the propagation speed is updated. The delay and gain parameters of each speaker are corrected according to the updated propagation speed until the sound pressure in each area meets the requirements.
