Introduction
e vocalist's performance, like all musical works, is dependent on the singer or performer's ability to reproduce the composer's work. e goal of singing is to use powerful vocal abilities to effectively convey the ideological content of songs, to infect the audience with haunting melodies, and to make the audience enjoy the art [1]. e human body is a marvelous human organ for the singer; its interpretation, expression, representation, and embodiment of human musical art is unmatched in any musical instrument in the world. Master the correct breathing technique as well as the correct voice. e sound's high position relates to complete headspace resonance, which we stress as mask resonance [2]. A focused, bright, relaxed, and penetrating sound resonates with the entire cavity of the head. Singing is more relaxing, and it sounds brighter and more wonderful [3]. Humming practice should help you achieve a high position sound. It seems to be that human body noise and transcription have a systemic connection with vocal music art expression, and it is useful to research the relationship model between vocal music art expression and the science of body noise in a person [4]. e Vocal Art Performance Network is suggested in conjunction with wireless sensors to capture artistic information of vocal music and gain control over the improvement of human body noise [5]. Network channel equation design and optimization of path detection algorithms, as well as path conflict avoidance design, are the fundamental technologies of vocal art expression and systemic control of human body noise science [6].
Wireless sensors are scientific and systemic ways of monitoring the expression of sound and noise art in the human body [7]. e optimization of the network causation node was governed through the design of routing protocol optimization and control of the wireless sensor route of the Internet of ings. Some research findings were discovered, including a network activation node that suggested a scientific and systemic control method for the human voice of wireless sensors without sound and performance [8]. To increase human body noise position, adaptive modulation coding has been used. Maximum sensor power management is used, and as a result, network node coverage capacity is increased [9]. is procedure, however, has issues with low stability and consistency in gathering voice art information from wireless sensors and systemic monitoring of human body science. A scientific and systematic method of human noise control and data collection based on wireless sensors with a strong and appealing understanding of node communication load is proposed in [10]. Wireless sensor nodes constructed the topological model of the routing graph of the voice information distribution route, checked the combined load and power of the wireless Internet sensor of things, and performed network routing conflict prevention design. ere are other problems with the control mechanism, such as less interference and less autonomous deployment capability [11]. It also investigates noise settings, noise extraction facilities, sound sampling quality, storage format, age of recorded items, number of recorded items, vocal music, and other topics and is of high standard and seriousness [12].
e study meets the standards by distinguishing between men and women, but the sound portion of the recorded object is unclear, and the kinds of sound signal collection and singing range are not defined. e preceding content is one of the most important factors determining the performance of Sound Music Art [13].
is research presents a mathematical framework for vocal expression and the science of human noise based on wireless sensors and a wireless node of convergence sensor model of vocal art. e HARTgraph routing model is used to create a structured design for vocal art and noise science. e wireless sensor is designed to make the best use of node models, and the convergent connection gain control technique is used to control wireless sensor vocal art performance. Furthermore, the adaptive balanced scheduling model is used for scientific and distributed tracking of vocal art performance as well as human body noise. e network of wireless sensors for acquiring information about vocal art is intended to better acquire information on vocal art and understand sound signal characteristics. We also enhance our ability to voice and detect the signal. Finally, simulation experiments are conducted in order to demonstrate the best performance of this technique in scientific and systemic performance and human noise analysis.

Methodology
In this section, we introduce vocal data using wireless sensors in order to control human corporal noise on a scientific and systematic level. Additionally, we develop an artistic expression of vocal music and a distribution model of human noise control nodes in wireless sensor and vocal performance, as well as a convergence link model for human noise control nodes.

Voice Signal Preprocessing.
e extraction of acoustic parameters is critical to the objective assessment of the body voice. e voice signal must be processed in advance, including digital, preaccentuation, framing, and window addition, regardless of the procedure used to extract and evaluate the parameters [14,15]. Supplementation is an important step in analyzing voice signals and extracting acoustic parameters. People's speech signals are analog, so the analog signals must be converted to digital signals before the digital signals can be processed and analyzed [16]. In this paper, a valuable and digitized voice data file is obtained by recording the singing voice signal with a microphone and a computer sound card and collecting it for later use [17]. After receiving the data file of the human voice signal, the signal is reweighted, and frame and window preprocessing is performed, which allows the signal after processing to satisfy the real needs; it is critical to increasing the accuracy of the subsequent data processing. Figure 1 depicts a noise signal that has been preconditioned [18].

Frame and Window.
e generation of speech signals is related to various movements of the organs of speech, and the random movement of the organs causes the signal itself to be unstable. However, the state of vocal organ changes is much slower than that of sound vibration [19]. erefore, it is considered that the speech signal is stable within 10-30 ms, and there is no obvious change in the characteristics of the speech spectrum and some physical properties in the short term. erefore, only the speech signal is divided into a few short speech segments, the processing method of the stationary signal can be introduced into the speech signal processing, and each segment here is called a short speech analysis frame. Each frame signal is regarded as a stationary process, which overcomes the difficulty of the speech signal analysis and processing, and the processing of each frame is equal to the long signal with invariant features. N sampling points are combined into one observation unit, called frame length. Usually, the frame length is 256 or 512, and the time is about 20-30 ms. e framing should be continuous; that is, it is not possible to replicate the frame, and the information is not presented and not processed between frames. e solution to this issue is to overlap the components so that frame and structure can maintain a smooth transition, which includes samples M, called frameshifts, usually 0-1/2 frame lengths. e signal is altered after framing from the original signals as the frames at start and end are stopped and need a window to be attached. Adding windows to the signal can not only effectively solve the problem of the discontinuity of the position signal at the beginning of the frame, but also make the original nonperiodic speech signal present the part of the periodic function. In the process of signal windowing, window functions are usually selected according to the nature and processing requirements of the signal being analyzed. e main part of the rectangular window is more concentrated, but the side lobe is high and there is a side lobe, which will transform the high-frequency interference and the leakage into the transform. It is suitable for the precise readout of the main lobe frequency but does not consider the signal processing of the amplitude accuracy. e peak value of the main lobe and the first side lobe peak decay to 40 dB, which is suitable for the analysis of the narrowband signals with strong interference noise as shown in Figure 2 for the preprocessed noise signal. e voice demands the involvement and collaboration of power bodies, vibrational organisms, resonance organisms, and the nervous system. Due to the incredibly intricate process, the voice function is a multidimensional and multiparameter evaluation of your voice with a complete and impartial assessment of your creative voice. It is important to have multidimensional acoustic signal parameters: selection and proper extraction of the technical signals of the voice utilizing vocal analysis, observation of the person's state in a pronunciation, assessment of whether the voice is normal and its regularity, and opening the doctor's diagnosis for an unbiased evaluation of the subsequent technique [20].

Vocal Performance and Human Noise Control Nodes
Convergence Link Model. To realize the information collection of vocal art based on wireless sensors and the scientific and systematic control of human body noise, firstly, the convergence link model of vocal art expression and human noise control node of a wireless sensor is constructed. e wireless sensor vocal art monitoring area is a square area with a side length of M, and there are N vocal art sensor routing relay nodes, assuming that the base station has sufficient energy. In the process of scientific and systematic control of vocal art and human noise, the energy balance control is carried out through the adaptive allocation of laser sensor routing nodes [21]. e information acquisition node of wireless sensor vocal music art is defined asi, based on the number of neighbor nodes, the number of hops and sampling interval T f between source and cluster head node is determined. e power consumed by cluster head node to transmit L bit data is set as T s � N f T f , and the equilibrium game between cluster head node and transmission link is carried out by using the game analysis method of node transmit power. e energy consumption of each node is obtained as follows: (1) e distributed routing detection algorithm is used to analyze the coverage of nodes through the shortest path deployment. Whenc j T c < T f ∀j ∈ [0, N f − 1], the base station of the wireless sensor network with vocal performance and human noise is located at the top of the monitoring area of the network at the initial moment [8].
e data packet forwarding of wireless sensor dominating point set is j∈S,j≠i x j r j (x)p i j (x). e characteristics of output power spectral density of vocal performance and human noise wireless sensor network converging link are obtained by using the conflict coordination control method: where c i � c th , and the sensor coefficient representing the artistic performance of the wireless sensor and the energy saving distribution of the nodes of the human noise control node estimates the minimum variance of the wireless sensor node η at any position and obtains the triggered node. e objective function of energy balance control is described as follows: arg max where argmax p i ∈P i u i is the frame head length of cluster head node i. e maximum likelihood estimation results of the convergence link model for the stability control of the vocal art performance sensor can be expressed as follows: where x(η) is the coverage of the sensor network based on the equivalent model of the vocal performance of the wireless sensor and the convergence link gain control of the human noise control node is constructed, and the trigger control between the vocal art performance and the human noise control node is carried out [22].

HART Graph Routing Algorithm and Routing Detection Protocol Design.
e HART graph routing model is used to design the route detection protocol for vocal performance and human noise wireless sensor networks. e HART map routing detection protocol is constructed based on the IEEE 802.3 EFM protocol, and M 1 M 2 · · · M N are the human body noise distribution under the wireless sensor. In the optimal network topology, the network transmission channel K r i is a two-way channel wireless transceiver channel, which is represented asr i (x), where mu(i, x) + np is the network node distribution density of the noise coverage area of the human body, and the network transmission channel mu(i, x) + np > 0 is the wireless transceiver channel of a twoway channel [9]. According to the HART graph routing model, the difference characteristic function of node output is obtained:

Es(j) � (u, v) ∈ E|u ∈ Vs(j), v ∈ Vs(j) . (5) e trigger node of the vocal art expression and the human body noise wireless sensor network is transformed into the link holomorphic analytical model, and the trigger node is repaired to obtain the relationship between the vocal music art expression and the human body noise wireless sensor network. e 2D coordinate system of the routing node is represented by(x u , y u ), and the artistic representation of vocal music is equivalent to the gain control model of the convergence link of the human noise control node in the following form: Based on the two-way link model(k, i), the vocal art expression of wireless sensor, and the design of human noise acquisition routing detection protocol model, the accuracy percentage of cluster head emission data is obtained: e cluster head node transmit data packet isCH i (i ∈ C 1 ), the channel equalization control method is used to calculate the average communication time interval of the first node [10]. For a given link gain coefficientc th , whenβ c 1 � u i ′ (c th ), vocal performance and human noise wireless sensor network, the overlay gain transfer function of the complex is described as e average amount of mutual information for the j reference node is From this, the correlation matching function between the artistic expression of vocal music and the root node and trigger node of the human body noise wireless sensor network is described as follows: where According to the above processing, a routing detection protocol based on the HART model and wireless network sensors is established.

Vocal music is conducted by using a vocal art format convergence model and the wireless sensor network human noise control node, as well as a routing detection protocol between vocal art expression and the wireless body noise sensor network. It optimizes the art of vocal music and the research and systematic management of human noise. e human noise science systematic control approach is used to control the wireless sensor's vocal art performance, as well as the convergent link control for the node of human noise control and the path between the vocal art expression and the human noise wireless sensors.
e numbers of conflicts and the delay are α l and τ l , respectively, where l ∈ [0, L − 1] τ 0 < τ 1 < . . . τ L− 1 , and the robust sexy radius GNInter i (n) of trigger node can be expressed as If CIntra i (n) is used to represent the energy overhead of the transmission of F-bit packets by node i and the maximum threshold for transmission packets of node CInter i (n), then the allocated power and time chips for each cluster head node are Based on this, the routing conflict avoidance mechanism of the Internet of things is designed, and the maximum probability density function of sensor node i effectively covering the monitoring area U i (n) in thet(n) time window is obtained as follows: By optimizing the topology design of the routing diagram of the vocal art expression and the human body noise wireless sensor network, the robustness coefficient of the vocal art expression and the human body noise wireless sensor network routing graph topology is obtained.
Among them, d is the artistic representation of vocal music and the routing transfer probability of the transmission node of the human noise wireless sensor network is the residual energy r of the cluster head, which is the current communication cycle of vocal art expression and human body noise wireless sensor network. erefore, the convergent link gains control of vocal performance, and the human noise control node is realized. e optimized control objective function is as follows: where when vocal art performance and human body noise wireless sensor network trigger node election as cluster head, set ru is 0; when there is a routing conflict, set the sensor transmission node connectivity cost coefficient equal to threshold d0; the residual energy of the triggered node gradually decreases; and vocal performance and human noise control node convergence link gain control matrix BN×1 are as follows: Multiplying the vocal performance with the node link matrix SN × L of the human body noise wireless sensor network and the energy matrix TL × 1 consumed by the node to receive the l bits data, thus realizing the expression of the vocal music art of the wireless sensor and the human body. Route detection and link gain control of noise control nodes.

Cluster Head Transmit Power Equalization Control and
Adaptive Equalization Scheduling. A control model equalizes voice performance and human noise with cluster head power. Wireless sensor networks are installed to implement the wireless sensor; the node is used for the optimal wireless sensor deployment and as an approach to the convergent link gain control. A balanced adaptive planning model is used to regulate vocal art and the noise of the human body scientifically. e communication load between wireless sensor vocal art performance and human noise control node is as follows: where In addition, ω(t) is the weight of routing conflict avoidance for intracluster nodes and p h (t) is the power attenuation of l bits data sent by wireless sensor vocal art information acquisition nodes. e payload overhead of the routing topology for the vocal performance and human noise wireless sensor network cluster heads and trigger nodes is obtained as follows: e routing conflict avoidance mechanism of the Internet of things is constructed and the RMS error of node robustness control is obtained by using the maximum likelihood estimation model. e calculation formula is expressed as follows: e message coverage of the triggering node has been strengthened because of the performance of the vocal music, the load of the human noise wireless sensor network, and the robustness perception coefficient from the source to the sink. e game model for robustness control of the information acquisition node of the wireless sensor sound music art is achieved as follows, following an autoadaptable rotation schedule:

To increase the control robustness of vocal music information acquisition nodes, the cluster head transmit power equalization control technique is used to implement adaptive equalization scheduling of wireless sensor nodes. e wireless sensor vocal art information collection vocal art performance and the human body noise scientific systemic control performance test simulation analysis result is shown in Table 1.
According to the analytical results in Table 1, the proposed method increases the signal collection of vocal music and the system analysis ability of the human body's noise signal. It has a robust ability to extract sound signal characteristics, a stronger ability to withstand noise interference, and a high test detection probability. Figure 5 demonstrates a performance test comparison that illustrates how this procedure can increase the accuracy of vocal and human noise detection.
In addition, Table 2 shows the medians and standard variations of diverse acquisition procedures. From Table 2, the current study's findings show that various types of data measurement techniques achieve comparable results for the chosen number of elements. In f0, F1, and F3 measures, as well as the associated statistical significance and variance factors, acquisition methods were observable. Furthermore, there were no significant changes in some time measures, such as the number of pauses and percentage pauses. Remarkably, there was some frequency and strength variability in the recording devices that remained constant.

Subjective Auditory Perception Evaluation.
Individual auditory evaluation is affected by personal measures and there are issues with precision and stability. It is undeniable that subjective auditory perception assessment is the only standard for testing and evaluating the performance of vocal music art as well as the validity of objective test parameters of human noise and sound function to provide directed signals for voice input training samples. e subjective auditory perception assessment of vocal voice and human noise is carried out to validate the efficacy of the human noise detection procedure.
