[0079] 1.

When training at different audience attendance rates, the different sound effects played by the audio equipment when the sound effect heard by the audience in the auditorium is always the required sound effect are formed into a data comparison set. Then, according to the actual audience attendance rate during the performance, different audio equipment start sound effects are provided so that the sound effect heard by the audience is closer to the required sound effect.

[0080] 2. The stage sound effect control system and method based on the PC system can obtain the number of tickets sold for the current stage performance before the formal start of the stage performance, thereby calculating the attendance rate of the current stage performance. Compare the attendance rate with the data comparison set to pre-determine the sound effect of turning on the audio equipment for the current stage performance. The pre-determined sound effect can eliminate the influence of different numbers of audiences on the sound effect propagation, so that the sound effect heard by the audience is closer to the required sound effect, improving the auditory experience of the audience, and further improving the overall effect of watching the stage performance.

[0081] 3. The stage sound effect control system and method based on the PC system can, during the formal performance of the stage performance, that is, during the playback of the stage sound effect, obtain the environmental noise in real time. When the environmental noise volume is large and there is a sound source with the same frequency as the sound effect in the environmental noise, the volume of the sound effect sound source in the currently played stage sound effect with the same frequency as the environmental sound source can be reduced to achieve the effect of balancing the target sound effect and the external environmental noise, thereby reducing the interference of the environmental noise on the audience in the auditorium receiving the target sound effect and ensuring the clarity of the target sound effect heard by the audience in the auditorium. When the environmental noise volume is large but there is no sound source with the same frequency as the sound effect in the environmental noise, the overall volume of the currently played stage sound effect can be increased so that the currently played stage sound effect can cover the environmental noise as much as possible, thereby reducing the interference of the environmental noise on the audience's ears receiving the stage sound effect and ensuring the clarity of the stage sound effect heard by the audience.

[0085] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0086] Embodiment 1, please refer to Figure 1 , a stage sound effect control system based on the PC system, including:

[0087] Collection module: Obtain layout data, required sound effects, the number of tickets sold for the current stage performance, and environmental noise data;

[0088] The layout data includes the performance stage layout, the auditorium layout, and the audio equipment layout;

[0089] The auditorium layout includes the auditorium area and the total number of auditorium seats;

[0090] The environmental noise data includes environmental noise sources, noise frequencies, and noise volumes;

[0091] 3D modeling module: Establish a 3D stage scene model in the PC system according to the layout data for simulating the stage sound effects;

[0092] Simulation training module: Perform simulation training in the 3D stage scene model according to the number of tickets sold for the current stage performance and the required sound effects to form a data comparison set for training different sound effects played by the audio equipment under different audience attendance rates, so that the sound effects heard by the audience in the auditorium are always the required sound effects;

[0093] Determination module: According to the number of tickets sold for the current stage performance and the data comparison set, form sound effect determination data by enabling the sound effect determination strategy for determining the sound effects of the audio equipment to be turned on for the current stage performance;

[0094] Regulation module: According to the environmental noise data, form sound effect adjustment data by enabling the sound effect adjustment determination strategy to adjust the stage sound effects in real time to reduce the interference of environmental noise on the stage sound effects.

[0095] Through the above-mentioned stage sound effect control system based on the PC system, it is possible to perform simulation training within the three-dimensional stage scene model according to the audience attendance rate and the required sound effects. During the training, when the sound effects heard by the audience in the auditorium are always the required sound effects under different audience attendance rates, different sound effects played by the sound equipment are formed to create a data comparison set. Before the official start of the stage performance, the number of tickets sold for this stage performance can be obtained, and then the attendance rate of this stage performance can be estimated. The corresponding stage sound effects can be selected from the data comparison set for playback, reducing the impact of different numbers of audiences on the stage sound effects. During the stage performance and the playback of the stage sound effects, the stage sound effects can be controlled according to the ambient noise, reducing the interference of the ambient noise on the audience's ears receiving the target sound effects and ensuring the clarity of the target sound effects heard by the audience.

[0096] Embodiment 2, please refer to Figure 2 , this embodiment is an improvement based on Embodiment 1. This embodiment also provides a method for a stage sound effect control system based on the PC system. Among them, simulation training is performed within the three-dimensional stage scene model according to the number of audiences and the required sound effects to form a data comparison set, which specifically includes:

[0097] Obtain the total number of seats in the stage auditorium and define it as the number of seats;

[0098] Obtain the number of audiences in different stage performance sessions and define it as the number of audiences;

[0099] Execute the attendance rate range determination strategy to extract the attendance rate range set A. Different target attendance rates indicate different numbers of audiences in the auditorium area. An increase in the number of audiences will increase the sound absorption ability, reduce sound reflection and echo, while a decrease in the number of audiences will increase sound reflection and echo and reduce the sound absorption ability. Therefore, when the sound equipment emits the same sound effect, different numbers of audiences will result in different sound effects transmitted to the ears of the audience;

[0100] Obtain the required sound effects, which are the sound effects that the audience in the auditorium needs to hear;

[0101] Execute the sound effect simulation training strategy for each element in the attendance rate range set A;

[0104] In this embodiment, the attendance rate range determination strategy specifically includes:

[0105] Obtain the total number of seats in the auditorium of the stage, and define it as the number of seats;

[0106] Obtain the number of audiences in different stage performance sessions, and define it as the number of audiences;

[0107] Calculate the attendance rate of different stage performance sessions, and define it as the target attendance rate. The target attendance rate = the number of audiences ÷ the number of seats;

[0108] Set the first threshold, the second threshold, the third threshold, and the fourth threshold, which are denoted as y1, y2, y3, and y4 respectively. Among them, the first threshold < the second threshold, the second threshold < the third threshold, the third threshold < the fourth threshold. The first threshold, the second threshold, the third threshold, and the fourth threshold are all thresholds for dividing the target attendance rate range. For example, the first threshold is 25%, the second threshold is 50%, the third threshold is 75%, and the fourth threshold is 100%;

[0109] Divide the target attendance rate into the first range, the second range, the third range, and the fourth range, and mark them as A1[0, y1], A2(y1, y2], A3(y2, y3], and A4(y3, y4] respectively;

[0110] Integrate A1, A2, A3, and A4 to form the attendance rate range set A.

[0111] In this embodiment, obtaining the required sound effect is specifically as follows:

[0112] Set the start time of the stage performance as the initial time point, and set the end time of the stage performance as the termination time point;

[0113] Set the adjustment duration. The adjustment duration is the interval duration for obtaining the adjustment time points between the initial time point and the termination time point, so that the duration between adjacent two adjustment time points is the adjustment duration. For example, the adjustment duration is 1 second;

[0114] Starting from the initial time point, calculate the adjustment time points between the initial time point and the termination time point according to the adjustment duration;

[0115] The adjustment time points include the first time point, the second time point... the nth time point, where the first time point = the initial time point + the adjustment duration, the second time point = the initial time point + (the adjustment duration × 2)... the nth time point = the initial time point + (the adjustment duration × n);

[0116] Obtain the initial time point, all adjustment time points, and the termination time point to form a time point set;

[0117] Obtain the time periods between every two adjacent elements in the time point set, and define them as the target time periods to form a time period set;

[0121] By using all the required sound sources of the sound effect corresponding to all the target time periods, the required sound effect frequency corresponding to all the required sound sources of the sound effect, and the required sound effect volume corresponding to all the required sound sources of the sound effect from the initial time point to the termination time point, form the required sound effect. The sound effects used in stage performances are generally: in different time periods, that is, according to the requirements of the performance in different time periods, different types of sound sources are mixed, and different sound sources are played at different frequencies and different volumes.

[0122] In this embodiment, the sound effect simulation training strategy specifically includes:

[0123] Obtain the required sound effect;

[0124] Define the required sound effect as the initial playback sound effect;

[0125] Turn on the audio device with the initial playback sound effect;

[0126] Obtain the auditorium area, such as Figure 3 as shown;

[0127] Obtain the four corner points of the auditorium area, which are respectively recorded as the first inflection point, the second inflection point, the third inflection point and the fourth inflection point, where the first inflection point and the third inflection point are not adjacent, and the second inflection point and the fourth inflection point are not adjacent;

[0128] Connect the first inflection point and the third inflection point to form the first connection line;

[0129] Connect the second inflection point and the fourth inflection point to form the second connection line;

[0130] Obtain the intersection point of the first connection line and the second connection line, and define it as the target measurement point;

[0131] S1. Real-time obtain the sound effect at the target measurement point, and define it as the measurement sound effect;

[0132] S2. If the measurement sound effect = the required sound effect, it indicates that when the audio device plays the initial playback sound effect, the sound effect heard by the audience in the auditorium meets the requirements, then define the initial playback sound effect as the preset sound effect;

[0133] If the measurement sound effect ≠ the required sound effect, it indicates that when the audio device plays the initial playback sound effect, the sound effect heard by the audience in the auditorium cannot meet the requirements, then execute the simulation adjustment strategy.

[0134] In this embodiment, the simulation adjustment strategy specifically includes:

[0135] Adjust the overall volume of the initial playback sound effect. Here, adjusting the overall volume of the initial playback sound effect means: adjusting the overall initial playback sound effect and uniformly increasing or decreasing the volume of all sound sources in each target time period;

[0136] Obtain the adjusted sound effect and define it as the adjusted sound effect;

[0137] Recognize the adjusted sound effect as the initial playback sound effect, and repeat steps S1 - S2 until the measured sound effect = the required sound effect.

[0138] Embodiment 3. This embodiment is an improvement based on Embodiment 2. The sound effect determination strategy is specifically included:

[0139] Obtain the ticket sales quantity of this stage performance, define it as the quantity of this performance, and predict the number of audiences of this stage performance according to the ticket sales quantity of this stage performance;

[0140] Calculate the attendance rate of this performance. The attendance rate of this performance = the quantity of this performance ÷ the number of seats;

[0141] Obtain the corresponding element in the control set for the attendance rate of this performance and define it as the target element;

[0142] Obtain the preset sound effect under the target element and define it as the target sound effect;

[0143] Then when it reaches the performance time, turn on the audio equipment with the target sound effect.

[0144] Embodiment 4. This embodiment is an improvement based on Embodiment 3. The sound effect adjustment determination strategy specifically includes:

[0145] Obtain all environmental noise sound sources in real time and define them as environmental sound sources;

[0146] Obtain the noise frequency of each environmental sound source in real time and define it as the environmental frequency;

[0147] Obtain the noise volume of each environmental sound source in real time and define it as the environmental volume;

[0148] Set a volume threshold. The volume threshold is the determination value of the environmental volume. By comparing the environmental volume with the volume threshold, determine whether the environmental sound source will affect the sound effect;

[0149] If the environmental volume ≥ the volume threshold, it indicates that this environmental volume is relatively large, and thus it indicates that the environmental sound source corresponding to this environmental volume will affect the sound transmitted from the target sound effect to the audience's ears. Then, define the environmental sound source corresponding to this environmental volume as the determined sound source;

[0150] Obtain the environmental frequency corresponding to the determined sound source and define it as the determined frequency;

[0151] Obtain all the sound sources currently playing in the target sound effect, and define them as the current sound sources;

[0152] Obtain the sound frequencies of all the sound sources currently playing in the target sound effect, and define them as the current source frequencies;

[0153] If it is determined that the frequencies do not overlap with the current source frequencies, it indicates that there is no sound source with the same frequency as the determined sound source among all the sound sources currently playing in the target sound effect. Then, increase the overall volume of the target sound effect. By increasing the overall volume of the target sound effect, the target sound effect can cover the ambient noise as much as possible, thereby reducing the interference of the ambient noise on the ears of the audience in the auditorium to receive the target sound effect and ensuring the clarity of the target sound effect heard by the audience in the auditorium;

[0154] If it is determined that the frequencies overlap with the current source frequencies, it indicates that there is a sound source with the same frequency as the determined sound source among all the sound sources currently playing in the target sound effect. Then, execute the local adjustment strategy.

[0155] In this embodiment, the local adjustment strategy specifically includes:

[0156] Extract the current source frequencies that are the same as the determined frequencies, and define them as the target source frequencies;

[0157] Obtain the current sound sources corresponding to the target source frequencies, and define them as the target sound sources;

[0158] Obtain the sound volumes of the target sound sources, and define them as the target source volumes;

[0159] Then, reduce the target source volume. By reducing the volume of the sound sources in the target sound effect that are the same as the ambient sound sources, the effect of balancing the target sound effect and the external ambient noise can be achieved, thereby reducing the interference of the ambient noise on the ears of the audience in the auditorium to receive the target sound effect and ensuring the clarity of the target sound effect heard by the audience in the auditorium.
