Description

Technical Field

[0001] The present invention relates to the technical field of noise hazard experience, and in particular to a noise hazard experience method and device. Background Art

[0002] Occupational noise is widely generated and exists in the production process and working environment of enterprises. Long-term exposure to noise can lead to different degrees of progressive and irreversible hearing loss. In the early stage, high-frequency hearing loss is the main cause, and speech frequency hearing loss gradually accumulates. It can also affect the human nervous, cardiovascular and cerebrovascular systems.

[0003] Workers in related jobs mainly wear protective earplugs or earmuffs in the production workshop to effectively avoid direct exposure to noise. However, due to their lax awareness of protection, workers often fail to use protective earplugs or earmuffs in accordance with standard specifications when they are in the production workshop, or even fail to take any protective measures. Providing occupational health training to workers and strengthening their awareness of protection are of great significance to improving their health level.

[0004] At present, most of the occupational health training is traditional offline or online training. Offline training is traditional classroom training, and online training is online learning training conducted on the Internet platform. It uses multimedia and physical objects to introduce the types and characteristics of occupational noise-induced hearing loss, noise protection methods and measures to workers. However, this type of occupational health training mainly introduces noise hazards and protection matters by playing promotional videos and text propaganda about noise hazards. It is difficult to give workers a profound education and personal experience. The training effect is not ideal, and it is unable to make workers intuitively feel the importance and necessity of using protective earplugs or earmuffs in a standardized manner for their own health, and the practicality is poor.

[0005] In view of this, overcoming the defects of the prior art is an urgent problem to be solved in the field of this technology. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a method and device for experiencing noise hazards. Its purpose is to provide a noise hazard experience processing flow in which an experiencer can set the noise protection state and noise conditions by himself, and based on the two noise protection states and the corresponding noise conditions, compare and draw noise protection suggestions, so that the experiencer can more intuitively experience the hearing state caused by improper wearing of protective earplugs or headphones through comparison, thereby solving the problem that the existing technology often fails to enable workers to intuitively feel the importance and necessity of using protective earplugs or earmuffs for their own health, resulting in poor practicality of this type of occupational health training method.

[0074] Embodiment 1:

[0075] In order to solve the above problems, an embodiment of the present invention provides a method for experiencing noise hazards, which simulates the noise protection status of an experiencer through a first dummy head and a second dummy head; multiple acoustic sensors are set inside the cochlea of ​​the first dummy head, and multiple acoustic sensors are set inside the cochlea of ​​the second dummy head, so as to determine the corresponding noise protection status by using the acoustic sensing.

[0076] In order to illustrate the noise hazard experience method of the embodiment of the present invention, the noise hazard experience device of the embodiment of the present invention is first introduced below:

[0077] like Figure 1 The front view of the experience device is shown. The main structure of the experience device is a display stand and a display stand. The display stand has a host ( Figure 1(not shown in the figure), the host is used to execute the noise hazard experience method of the embodiment of the present invention; there are two earphone slots in the middle of the display stand for placing earphones, so that the experiencer can take and wear the earphones; there are two models of dummy heads (the first dummy head and the second dummy head respectively) and several earplugs on the display surface of the display stand, so that the experiencer can insert the earplugs into the external auditory canal of the dummy head to simulate the protective measures adopted by himself. When the experiencer is conducting the simulated experience, he uses noise protection devices such as earplugs and earmuffs to adjust the noise protection state to the noise protection state when he is working. In an optional embodiment, the earphones in the earphone slots can be used instead of earmuffs; when the experiencer takes out the earphones from the earphone slots, he wears the earphones on the dummy head to cover the ears of the corresponding dummy head.

[0078] In an optional embodiment, the experience device can be placed in an actual production workshop to simulate the noise environment in advance, so that the operators can enhance their awareness of protection as experiencers; and a legend of the standard noise protection method and its description can be set above the display screen ( Figure 1 ), to emphasize the standard noise protection mode.

[0079] like Figure 2 As shown, the methods of experiencing the noise hazard include:

[0080] Step 10: Obtain a first noise protection state and a first noise condition of the first dummy head; and obtain a second noise protection state and a second noise condition of the second dummy head.

[0081] Among them, the first noise protection state refers to the state to which the noise protection device on the first dummy head is adjusted by the experiencer during this experience. The first noise condition refers to: the noise environment condition of the first dummy head that the experiencer needs to simulate during this experience; for example: noise decibel number and noise duration, noise exposure level, experiencer gender, experiencer age, experiencer job type and experiencer industry, etc. The adjustable noise protection state and settable noise conditions of the first dummy head and the second dummy head are the same, which will not be repeated here. In an optional embodiment, the experiencer can be prompted by text on the display screen to set different noise protection states and / or noise conditions for the first dummy head and the second dummy head, respectively.

[0082] Step 20: According to the first noise protection state and the first noise condition, obtain the first hearing state corresponding to the first dummy head, and display the first hearing state; according to the second noise protection state and the second noise condition, obtain the second hearing state corresponding to the second dummy head, and display the second hearing state.

[0083] The embodiment of the present invention uses two dummy heads to simulate the hearing status of the experiencer in different states, and presents them on the display screen in a comparative manner, so that the experiencer can intuitively feel the impact of the noise protection state on the hearing state.

[0084] Step 30: Obtain noise protection suggestions based on the first hearing status and the second hearing status, and display the noise protection suggestions to warn the experiencer to perform noise protection according to the noise protection suggestions.

[0085] The present invention simulates the noise protection state of an experiencer through a first dummy head and a second dummy head; a plurality of acoustic sensors are arranged inside the cochlea of ​​the first dummy head and the second dummy head, so as to determine the corresponding noise protection state by using acoustic sensing; a first noise protection state and a first noise condition of the first dummy head are obtained, thereby obtaining a first hearing state corresponding to the first dummy head, and displaying the first hearing state; a second noise protection state and a second noise condition of the second dummy head are obtained, thereby obtaining a second hearing state corresponding to the second dummy head, and displaying the second hearing state; according to the first hearing state and the second hearing state, noise protection suggestions are obtained and displayed, so as to warn the experiencer to perform noise protection according to the noise protection suggestions, so that the experiencer can more intuitively experience the deterioration of the hearing state caused by the improper use of protective earplugs or earmuffs through comparison, thereby solving the problem that the prior art often fails to enable operators to intuitively feel the importance and necessity of the standardized use of protective earplugs or earmuffs for their own health, resulting in poor practicality of such occupational health training methods.

[0086] The display screen of the embodiment of the present invention is used to interact with the experiencer, such as Figure 3 The following is a specific example of the main interface of the system displayed on a display screen. The experiencer follows the corresponding operating instructions on the display screen to complete the following steps of occupational health training. When the experiencer selects the "Know Ear" section by clicking on the display screen in the main interface of the system, it jumps to the following Figure 4 When the user selects the "Hearing Loss Simulation" section by clicking on the display screen in the main interface of the system, the user will first jump to the following Figure 5 The user will be prompted to adjust the noise protection status of the dummy head according to their own noise protection habits and set the noise conditions according to their own working environment to start the interactive experience. When the user selects the "How the Ear Hears Sound" section by clicking on the display screen in the main interface of the system, the user will be redirected to the following interface: Figure 6 The video interface shown plays the occupational health protection introduction video by default.

[0087] The following is a description of the processing flow of the noise hazard experience device of the embodiment of the present invention during the interactive experience process. Figure 7The figure shows a schematic diagram of a unilateral external auditory canal of a dummy head. When the experience method of wearing earplugs is adopted, in order to provide the experiencer with a realistic noise simulation experience, before entering the noise experience state, the experiencer respectively sets corresponding earplugs in the external auditory canal of the first dummy head and the external auditory canal of the second dummy head, so as to use the earplugs to simulate different noise protection states of the experiencer.

[0088] In step 10, if Figure 8 As shown, obtaining the first noise protection state of the first dummy head includes:

[0089] Step 101: Acquire the earplug protection status from the pressure sensor group on the external auditory canal of the first dummy head; wherein the pressure sensor group includes a plurality of pressure sensor dot arrays, and each pressure sensor dot array is distributed at a different position on the external auditory canal.

[0090] In the embodiment of the present invention, a pressure sensor group is arranged in the external auditory canals on both sides of each dummy head to collect the pressure on the inner wall of the external auditory canal and judge the noise protection status of the earplug when the earplug is worn. Fig. 9 The figure shows a specific example of a pressure sensor group arranged in a unilateral external auditory canal. Each black dot on the external auditory canal represents a pressure sensor dot matrix. Each pressure sensor dot matrix may include a plurality of micro pressure sensor points (such as Fig. 9 (not shown), each micro pressure sensor collects the pressure value received and summarizes it as dot matrix data. Fig. 9 As shown, the pressure sensor array can be evenly distributed on the inner wall surface of the external auditory canal, so as to achieve the purpose of using the pressure sensor group in the embodiment of the present invention to achieve full coverage monitoring of the pressure on the inner wall of the external auditory canal.

[0091] The principle of setting the pressure sensor array in the external auditory canal is to cover as many positions in the external auditory canal as possible that may be touched by the earplug; in an optional embodiment, the setting method of the pressure sensor array in the external auditory canal can also be selected by technical personnel in this field according to the specific usage scenario, and is not limited here.

[0092] Step 102: Obtain the external auditory canal pressure collected by the pressure sensor group based on the dot matrix data collected by each pressure sensor dot matrix and the pressure weight of the pressure sensor dot matrix; wherein the pressure weight is set according to the position of each pressure sensor dot matrix.

[0093] For example, for a contact area where there is no need to completely eliminate a gap between the earplug and the external auditory canal (eg, a deeper area close to the inner side of the ear canal), the pressure weight of the contact area may be set to 0.

[0094] Step 103: When the external auditory canal pressure is greater than or equal to a pressure threshold, it is determined that the first dummy head enters a noise experience state.

[0095] The pressure threshold is selected by those skilled in the art according to specific usage scenarios and is not limited here.

[0096] Step 104: when the first dummy head enters a noise experience state, a first noise protection state in the earplug protection state is obtained.

[0097] After the experiencer sets the earplugs on both sides of the first dummy's head according to his or her own wearing habits, he or she enters the noise experience state and collects corresponding data through the sensor to obtain the first noise protection state.

[0098] Specifically, in an optional embodiment, as Fig.10 As shown, step 104 includes:

[0099] Step 1041: Before the first dummy head enters the noise experience state, the ambient decibel magnitude is obtained from a plurality of acoustic sensors inside the cochlea of ​​the first dummy head; wherein the plurality of acoustic sensors are arranged inside the cochlea of ​​the first dummy head according to the positions of the auditory receptors of the human ear.

[0100] The acoustic sensor refers to a sensor that can collect corresponding sound data; in an optional embodiment, a sound level sensor can be used to collect the decibel number of the sound, or an acoustic wave sensor can be used to collect the signal strength of the sound.

[0101] Step 1042: When the first dummy head enters a noise experience state, the protection decibel magnitude is obtained from the multiple acoustic sensors.

[0102] Step 1043: Compare the environmental decibel level with the protection decibel level to obtain the first noise protection state.

[0103] The embodiment of the present invention achieves complete coverage of the noise protection status through a dense sensor layout, and can simulate the noise protection status of the experiencer as much as possible through a dummy head. By adjusting the noise protection status and setting noise conditions according to personal habits, the experiencer can actually participate in occupational health training in a content-scene interactive manner.

[0104] In step 20, if Fig.11 As shown, obtaining the first hearing state corresponding to the first dummy head according to the first noise protection state and the first noise condition includes:

[0105] Step 201a: Determine an applicable hearing loss simulation model based on the simulation factors involved in the first noise condition; wherein the simulation factors include length of time exposed to noise, average daily exposure duration, noise intensity and type of work.

[0106] Among them, the hearing loss simulation model is selected by technical personnel in this field according to specific simulation factors, which is not limited here; in an optional embodiment, a network structure based on convolutional neural network fine-tuning can be used as the hearing loss simulation model to be trained; and the corresponding simulation factors and their corresponding medical imaging images of the hearing status are used as training inputs to obtain the trained hearing loss simulation model.

[0107] Step 202a: Using the hearing loss simulation model, determine the first noise condition and the first hearing state under the first noise protection state.

[0108] The first noise condition and the first noise protection state are input into the trained hearing loss simulation model to obtain a corresponding first hearing state.

[0109] In an optional embodiment, the embodiment of the present invention is based on data in related papers and combines the first noise condition and the first noise protection state through software to reversely simulate the first hearing state.

[0110] You can refer to relevant papers to establish the relationship between the gender, age, industry, and size of the enterprise of the experiencer and the high-frequency hearing loss rate of those exposed to occupational noise:

[0111] Relevant data show that among the 8264 people exposed to occupational noise, 6217 were male and 2047 were female, accounting for 75.23% and 24.77% respectively. The data were entered and a database was established using Excel, and statistical analysis was performed using SPSS software; the enumeration data were expressed as [n(%)], and the comparison of rates was performed using x 2 The statistical results are as follows: the average high-frequency hearing threshold of both ears of 881 people is ≥40db(A), and the high-frequency hearing loss rate is 10.66%, 12.87% (800) for males and 3.96% (81) for females. The high-frequency hearing loss rate of occupational noise exposure increases with age (x 2Trend = 232.80, P < 0.0.5), and increased with the increase of working years. The high-frequency hearing loss rate of occupational noise exposure workers was the highest in mining and construction industries (21.43%), followed by wholesale and retail industries (13.94%); the high-frequency hearing loss rate of occupational noise exposure workers in different economic types of enterprises was from high to low: state-owned enterprises (13.66%) > private enterprises (10.78%) > collective enterprises (9.26%) > foreign-funded enterprises (4.87%) > Hong Kong, Macao and Taiwan enterprises (4.27%). The high-frequency hearing loss rate of enterprises of different sizes was the highest in large enterprises (14.36%), followed by small enterprises (11.89%) and micro-enterprises (10.56%).

[0112] You can also refer to relevant papers to establish the relationship between the experiencer's job type, noise exposure level, experiencer's gender and the high-frequency hearing loss rate of those exposed to occupational noise:

[0113] In the first reference, a total of 2052 workers from 18 production units of four petrochemical enterprises were surveyed, and their job noise ranged from 83.2 to 86.7 dB(A); 878 workers were exposed to job noise exceeding the standard, with an exceeding rate of 42.8%; among them, the job with the highest noise exposure intensity (i.e., the experiencer's job) was the auxiliary boiler turbine operator, with an average job noise of (86.7±6.6) dB(A). 61.1% of the jobs had a cumulative job noise exposure of >95.0 dB(A)·year; the job with the highest cumulative job noise exposure (i.e., noise exposure level) was the operator outside the petroleum coke hydrogen production unit (including purification workers, air separation workers, and gas chemical workers), with an average of (97.7±3.6) dB(A) / year. The cumulative job noise exposure of different exposure levels was divided into 6 groups with a cumulative job noise exposure interval of 3.0 dB(A) / year as one group, and the relationship between cumulative job noise exposure and hearing loss at each frequency was analyzed. The results showed that at frequencies of 2.0, 3.0, 4.0, 6.0 kHz and high frequencies, the detection rates of hearing loss in the subjects gradually increased with the increase of cumulative noise exposure at work. The detection rates of hearing loss at frequencies of 0.5, 1.0 kHz and speech frequency did not show the above pattern. In general, when the cumulative noise exposure at work was ≥94.0 dB(A) / year, the detection rates of hearing loss at each frequency increased sharply.

[0114] In the second reference, 39 wooden furniture manufacturing workplaces and 852 wooden furniture noise workers were selected in the High-tech Zone of Changshou District, Chongqing from 2021 to 2023. The noise intensity of the workplace was detected, and the noise exposure level of noise workers was measured. GBZ / T 229.4-2012 "Grading of Occupational Disease Hazards in the Workplace" was used to evaluate the degree of noise hazard in different positions, and WS / T 754-2016 "Guidelines for Risk Management of Noise Occupational Disease Hazards" was used to predict the risk of high-frequency hearing loss (HFHL) and occupational noise-induced deafness (ONID) in noise workers at different positions at the age of 50, 55, and 60. The results showed that the noise exceeding standard rate in the workplace of wooden furniture manufacturing industry was 32.7%; the maximum value of the equivalent sound level of 8 hours or 40 hours per week to which workers in 10 noise-related positions were exposed was 87.3 to 96.5 dB(A). Except for the positions of wiping boards and spray painting, the noise hazard level of the positions of board making, edge banding, fine cutting, carving and grinding was moderate, while the noise hazard level of the positions of cutting, making and special-shaped was severe, with a greater risk of noise hazard. The abnormal detection rate of HFHL in workers in various noise-related positions was 15.7%, and the abnormal detection rate of ONID was 6.6%. The risk of HFHL and ONID caused by noise in workers in various positions increased with the increase of years of exposure. Among them, the risk of HFHL in workers who were ≥50 years old was high for workers who were cutting, making, special-shaped, fine cutting and carving. The risk of HFHL in workers who were ≥60 years old was high for workers who were ≥50 years old. The risk of HFHL in workers who were ≥60 years old was high for workers who were ≥50 years old except for workers who were wiping boards and spray painting. The risk of ONID among workers in cutting, production, special-shaped, edge-banding, fine-cutting, carving and polishing at the age of ≥50 years was high; among them, the risk of ONID among workers in cutting and production was high when they worked to the age of 60 years. Conclusion The noise intensity in the workplace of wooden furniture manufacturing industry was high; cutting, production, special-shaped, edge-banding, fine-cutting, carving and polishing were the key risk points, and the risk level of high-frequency hearing loss and occupational noise-induced deafness among workers was high.

[0115] In the third reference, noise detection results of automobile manufacturing enterprises in a certain area and occupational health examination data of noise workers were collected, and x 2The noise detection rate of enterprises exceeding the standard and the high-frequency hearing loss of noise-exposed workers were tested and analyzed, and multiple influencing factors of high-frequency hearing loss were analyzed by logistic regression. The results showed that the noise exceeding standard rate of automobile manufacturing enterprises in a certain district was 11.20%, among which the noise exceeding standard rate of the assembly workshop was the highest, at 26.32%; the high-frequency hearing loss detection rate of 3346 noise-exposed workers was 7.71%, and it showed an increasing trend with age and length of service (x 2 =36.018, 34.195, P<0.01); the detection rates of high-frequency hearing loss among noise workers in enterprises of different scales, economic types and different noise exposure conditions were compared, and the differences were statistically significant (x 2 =59.847, 27.976, 54.838, P<0.01), among which workers in small-scale and domestic enterprises and those exposed to noise + welding fume had higher rates of high-frequency hearing loss. The results of multivariate logistic regression analysis showed that age, length of noise exposure, and noise exposure were all influencing factors for high-frequency hearing loss in noise-exposed workers. Noise-exposed workers aged ≥40 years, length of noise exposure ≥10 years, and those exposed to noise + welding fume had an increased risk of high-frequency hearing loss (OR=1.707, 1.591, 1.606, P<0.05).

[0116] In the fourth reference, from May to December 2021, according to the "Beijing 2021 Workplace Occupational Disease Hazard Factor Monitoring Work Plan", a convenient sampling method was used to select four key industries in Beijing from 16 districts across the city, printing and recording media reproduction industry, automobile manufacturing industry, metal products industry and electronic equipment manufacturing industry as the research objects. On-site testing of the noise exposure intensity of key positions in the four key industries was carried out, and the results of the binaural average high-frequency hearing threshold examination of workers in noise-exposed key positions were derived from the "Occupational Disease and Health Hazard Factor Monitoring Information System". A two-level logistic regression was used to perform a multivariate analysis of hearing loss. Results: A total of 125 enterprises were included in this survey, and the noise intensity exceeded the standard rate of 14.6%. The differences in the noise intensity exceeding the standard among key industries were statistically significant (x 2=5.882, P=0.032). The hearing loss rate in the electronic equipment manufacturing industry was the highest, at 43.4%. The results of multivariate analysis showed that workers in the electronic equipment manufacturing industry had a higher incidence of hearing loss than those in the printing and recording media reproduction industry (P=0.001, OR=5.0, 95%CI: 2.1 to 12.0). Compared with workers in the age group under 30 years old, the risk of hearing loss in the 30-50 and >50 years old groups increased (P<0.001, OR=2.5, 95%CI: 1.8 to 3.3; P<0.001, OR=3.9, 95%CI: 2.7 to 5.8). Compared with women, men had an increased risk of hearing loss (P=0.035, OR=1.8, 95%CI: 1.1 to 3.0). Conclusion: The overall level of noise intensity exceeding the standard in Beijing is relatively low, but prevention and control still need to be paid attention to. The noise intensity exceeding standard rate and the hearing loss rate among workers in the electronic equipment manufacturing industry are both high. The risk of hearing loss increases with age, and the risk of hearing loss in men is higher than that in women.

[0117] After the first hearing state is generated, in order to intuitively and multi-dimensionally show the severity of occupational noise-induced hearing loss to the experiencer, in step 20, Fig.12 As shown, the displaying of the first hearing state includes:

[0118] Step 201b: Use the horizontal axis to represent a simulation factor and the vertical axis to represent a state type of the first hearing state, and generate at least one first demonstration diagram of the first hearing state; wherein the state type of the first hearing state includes hearing loss rate, hearing range or deafness age.

[0119] Step 202b: Display the at least one first demonstration diagram to display the first hearing status through the at least one first demonstration diagram.

[0120] In an optional embodiment, the process of interaction between the experiencer and the display screen is as follows: after the experiencer adjusts the first dummy head and the second dummy head to two noise protection states that the experiencer is accustomed to, the display screen prompts the experiencer to set the corresponding first noise condition, and then starts the calculation according to the processing flow of the embodiment of the present invention to obtain the corresponding first hearing state and second hearing state; for example, at about 240 working hours, the first noise protection state corresponds to the first hearing state.

[0121] To illustrate the process of generating noise protection suggestions after the experiencer adjusts the noise protection state each time, in step 30, Fig.13 As shown, obtaining noise protection suggestions according to the first hearing state and the second hearing state includes:

[0122] Step 301: Determine a first protection difference between the first noise protection state and a standard noise protection state; determine a second protection difference between the second noise protection state and the standard noise protection state; determine a comparative protection difference between the first protection difference and the second protection difference.

[0123] For example, the standard noise protection state is: the pressure values ​​collected by all pressure sensor arrays are within the normal pressure range; compared with the standard noise protection state, in the first noise protection state, the pressure values ​​collected by the first pressure sensor array, the third pressure sensor array, the fourth pressure sensor array and the fifth pressure sensor array are not within the normal pressure range; the pressure values ​​collected by the remaining pressure sensors are all within the normal pressure range; compared with the standard noise protection state, in the second noise protection state, the pressure values ​​collected by the third pressure sensor array and the fifth pressure sensor array are not within the normal pressure range; the pressure values ​​collected by the remaining pressure sensors are all within the normal pressure range. The first protection difference is: the protection area corresponding to the first pressure sensor array, the third pressure sensor array, the fourth pressure sensor array and the fifth pressure sensor array; the second protection difference is: the protection area corresponding to the third pressure sensor array and the fifth pressure sensor array; the comparative protection difference is: the protection area corresponding to the first pressure sensor array and the fourth pressure sensor array.

[0124] Step 302: Compare the first hearing state and the second hearing state with the normal hearing state respectively, and generate corresponding noise protection suggestions based on the comparison results, as well as the first protection difference, the second protection difference and the compared protection difference.

[0125] In an optional embodiment, when the state difference between the first hearing state and the normal hearing state is less than or equal to a first difference threshold, and the state difference between the second hearing state and the normal hearing state is greater than the first difference threshold, the standard protection method corresponding to the second protection difference can be determined as the corresponding noise protection recommendation; and / or, the first protection difference can be determined as an acceptable protection method, and a prohibited protection method can be determined based on the comparative protection difference; and based on the acceptable protection method and the prohibited protection method, a corresponding noise protection recommendation can be generated.

[0126] Among them, the state difference is the numerical difference used to judge indicators such as the hearing state and the auditory frequency range; when the state difference exceeds the first difference threshold, the corresponding hearing state is a state that has reached the diagnosis and treatment indications of occupational noise-induced hearing loss. The first difference threshold is selected by technical personnel in this field according to the specific usage scenario. In an optional embodiment, an occupational noise-induced hearing loss AI diagnostic and recognition model can be used to judge the state difference between the first hearing state and the normal hearing state, as well as to judge the state difference between the second hearing state and the normal hearing state. The standard protection method corresponding to the second protection difference is, for example, the standard protection method corresponding to the area detected by the first pressure sensor array and the second pressure sensor array, that is, a protection method that enables the pressure value collected in the corresponding area to be within the normal pressure range.

[0127] In an optional embodiment, when the second hearing state has reached the diagnosis and treatment indication of occupational noise-induced hearing loss, it indicates that the noise protection method corresponding to the second protection difference is very likely to cause occupational noise-induced hearing loss, so the standard protection method corresponding to the protection method is used as a noise protection recommendation. For example, the noise protection state depends on the key points of the six noise protection methods. Strict compliance with any key point can make the pressure value of the area detected by at least one pressure sensor dot matrix within the normal pressure range. The six key points are: the first key point, the second key point, the third key point, the fourth key point, the fifth key point and the sixth key point; for example, the first key point can be whether the earplug is close to the first pressure sensor dot matrix on the outermost side of the external auditory canal. The standard protection method of the first key point is to adjust the earplug so that the earplug is close to the first pressure sensor dot matrix on the outermost side of the external auditory canal to reach the corresponding pressure value. The second protection difference is reflected in the first key point, the second key point, the third key point and the fourth key point. The text of the standard protection method of the first key point, the standard protection method of the second key point, the standard protection method of the third key point and the standard protection method of the fourth key point are used as noise protection recommendations.

[0128] In another optional embodiment, since the first hearing state does not meet the diagnosis and treatment indications of occupational noise-induced hearing loss, when taking protective measures, especially when providing noise protection suggestions for the experiencer in the short term, considering that the experiencer is often unable to strictly comply with every key point in the standard protection method immediately, the impact of the first protection difference on the hearing state can be temporarily ignored, and the first protection difference can be determined as an acceptable protection method. Since only one of the first hearing state and the second hearing state meets the diagnosis and treatment indications of occupational noise-induced hearing loss, the contrast protection difference that causes the difference in the hearing states of the two may be the key to causing occupational noise-induced hearing loss; because the first protection difference violates fewer key points than the second protection difference, the contrast protection difference is determined as a prohibited protection method. When generating noise protection suggestions, it can be clearly pointed out that the acceptable protection method has little impact on the hearing state in the short term, and it is recommended that the experiencer focus on the prohibited protection method when working, and protect against noise as much as possible according to the standard protection method of the corresponding key points.

[0129] For example, the first protection difference is reflected in the first and second points, the second protection difference is reflected in the first, second, third and fourth points, and the contrast protection point is reflected in the third and fourth points. The noise protection recommendations are: it is recommended to immediately adjust to the standard protection method of the third and fourth points; in the short term, noise can be protected according to the noise protection method of the first protection difference, and it is recommended to adjust to the standard protection method of the first and second points as soon as possible.

[0130] In addition, the contents generated by the generation methods of the above two embodiments may also be combined into noise protection suggestions.

[0131] When the state difference between the first hearing state and the normal hearing state is greater than a first difference threshold, and the state difference between the second hearing state and the normal hearing state is less than or equal to the first difference threshold, the standard protection method corresponding to the first protection difference is determined as the corresponding noise protection recommendation; and / or, the second protection difference is determined as an acceptable protection method, and a prohibited protection method is determined based on the comparative protection difference; and based on the acceptable protection method and the prohibited protection method, a corresponding noise protection recommendation is generated.

[0132] Similarly, in an optional embodiment, when the first hearing state has reached the diagnosis and treatment indication of occupational noise-induced hearing loss, it means that the noise protection method corresponding to the first protection difference is very likely to cause occupational noise-induced hearing loss, so the standard protection method corresponding to the protection method is used as a noise protection recommendation. For example, the first protection difference is reflected in the first point and the second point, and the text of the standard protection method of the first point and the standard protection method of the second point are used as noise protection recommendations.

[0133] In another optional embodiment, since the second hearing status does not meet the diagnostic and treatment indications for occupational noise-induced hearing loss, when taking protective measures, the impact of the second protection difference on the hearing status can be temporarily ignored, and the second protection difference can be determined as an acceptable protection method; because the first protection difference violates fewer key points than the second protection difference, the key points other than the comparison protection difference (i.e., the first key point and the second key point) are determined as prohibited protection methods. For example, the noise protection recommendation is: it is recommended to immediately adjust to the standard protection method of the first and second key points; in the short term, noise can be protected according to the noise protection method of the second protection difference, and it is recommended to adjust to the standard protection method of maintaining the third and fourth key points as soon as possible.

[0134] In addition, the contents generated by the generation methods of the above two embodiments may also be combined into noise protection suggestions.

[0135] When the state difference between the first hearing state and the normal hearing state is greater than a first difference threshold, and the state difference between the second hearing state and the normal hearing state is greater than the first difference threshold, the standard protection methods corresponding to the first protection difference and the second protection difference are determined as corresponding noise protection recommendations.

[0136] Among them, when the first hearing status and the second hearing status have both reached the diagnostic and treatment indications of occupational noise-induced hearing loss, it means that the noise protection methods corresponding to the first protection difference and the second protection difference are very likely to lead to the occurrence of occupational noise-induced hearing loss. Therefore, the standard protection methods of the corresponding key points are regarded as behaviors that need to be corrected in the noise protection recommendations.

[0137] When the state difference between the first hearing state and the normal hearing state is less than or equal to a first difference threshold, and the state difference between the second hearing state and the normal hearing state is less than or equal to the first difference threshold, the standard protection method is determined as the corresponding noise protection recommendation.

[0138] Among them, when both the first hearing status and the second hearing status do not meet the diagnostic and treatment indications of occupational noise-induced hearing loss, it means that the noise protection methods corresponding to the first protection difference and the second protection difference have a small probability of leading to occupational noise-induced hearing loss. There is no need to generate targeted noise protection recommendations, and it is sufficient to provide standard protection methods for the experiencer for reference.

[0139] In order to make the experiencer more intuitively feel the serious consequences of not taking noise protection measures in a standardized manner, the embodiment of the present invention also provides an experience process for the experiencer to simulate the hearing state that may be achieved under different noise protection states. The experiencer wears noise reduction headphones on the first dummy head and the second dummy head respectively, so as to simulate the different noise protection states of the experiencer through the noise reduction headphones.

[0140] Among them, the noise reduction headset is a Bluetooth headset, which can transmit audio files and has the function of playing audio.

[0141] like Fig.14 As shown, after displaying the noise protection suggestion, it also includes:

[0142] In step 401, prompt information indicating whether the first noise protection state or the second noise protection state is experienced is displayed.

[0143] In step 402, when the experiencer chooses to experience the first noise protection state or the second noise protection state, the standard noise protection state is transmitted to the noise cancelling headphones, so that the noise cancelling headphones play the standard protection noise audio, so that the experiencer can feel the protection effect of the standard noise protection state; wherein, the standard protection noise audio is the sound information audible to the human ear in the standard noise protection state.

[0144] Among them, the standard protection noise audio is selected by technical personnel in this field according to the specific usage scenario.

[0145] In step 403, the decibel level of the original noise audio is reduced to a level that does not damage hearing, thereby obtaining the target noise audio; wherein the original noise audio is sound information audible to the human ear generated based on the hearing state under the noise conditions selected by the experiencer.

[0146] Among them, the original noise audio is selected by technical personnel in this field according to the specific usage scenario; the level that does not damage hearing means that after listening to the original noise audio, the hearing status of the experiencer will not be permanently damaged, and the specific order of magnitude range of the level that does not damage hearing is selected by technical personnel in this field according to the specific usage scenario.

[0147] When the decibel level of the original noise audio reaches a level that damages hearing, in an optional embodiment, the decibel level difference between the original noise audio and the target noise audio can be displayed on the display screen while the decibel level of the original noise audio is reduced, and the experiencer is prompted that "to protect your hearing, the decibel level of the original noise audio has been reduced to a level that does not damage hearing, and the actual decibel level difference between the target noise audio you hear and the original noise audio is X times". When the decibel level of the original noise audio is a level that does not damage hearing, there is no need to reduce the decibel level of the original noise audio, and the original noise audio is directly used as the target noise audio.

[0148] In step 404, the target noise audio is transmitted to the noise cancelling headphones, so that the noise cancelling headphones play the target noise audio and display the decibel magnitude by which the original noise audio is reduced, so that the experiencer can feel the difference in protection effect between the selected noise protection state and the standard noise protection state without damaging the experiencer's hearing.

[0149] After the user puts on the noise-canceling headphones, since the noise-canceling headphones have isolated the external environmental noise, when the noise-canceling headphones play the standard protection noise audio, they can bring the user the noise experience of wearing specific earplugs or headphones according to standard protection measures. Then, when the noise-canceling headphones play the target noise audio, they can bring the user the noise experience of not wearing specific earplugs or headphones according to standard protection measures. By comparing the two noise audios, the protection effect of the standard noise protection state is intuitively displayed to the user.

[0150] The embodiment of the present invention guides the experiencer to wear the corresponding noise-canceling headphones and play the corresponding preset audio through the noise-canceling headphones, so that the experiencer can experience the sound information audible to the human ear in the standard noise protection state and the noise protection state selected by the experiencer, so as to intuitively experience the difference in protection effects.

[0151] like Fig.15 As shown, after displaying the noise protection suggestion, it also includes:

[0152] In step 501, prompt information indicating whether the first hearing state is experienced is displayed.

[0153] In step 502, when the experiencer chooses to experience the first hearing state, based on the first hearing state, the impairment experience audio corresponding to the normal experience audio is generated; wherein the normal experience audio is the sound information audible to the human ear in the normal hearing state.

[0154] Among them, the normal experience audio is selected by technical personnel in this field according to the specific usage scenario.

[0155] In step 503, both the normal experience audio and the impairment experience audio are sent to the noise cancelling headphones, so that the noise cancelling headphones play the normal experience audio and the impairment experience audio respectively, so that the experiencer can feel the auditory difference between the normal hearing state and the first hearing state.

[0156] After the user puts on the noise-canceling headphones, since the noise-canceling headphones have isolated the external environmental noise, when the noise-canceling headphones play the normal experience audio, the user can first intuitively feel the hearing state before the hearing level drops by listening to the normal experience audio. Then, when the noise-canceling headphones play the damage experience audio, the user can intuitively feel the hearing state after the hearing level drops by listening to the damage experience audio. By comparing the two experience audios, based on the simulated hearing level that may be brought about by the protective measures taken by the user, the user is provided with a real experience of hearing loss.

[0157] The embodiment of the present invention guides the experiencer to wear the corresponding noise-canceling headphones and plays the corresponding experience audio through the noise-canceling headphones, so that the experiencer can experience the sound information audible to the human ear in the normal hearing state and the first hearing state, so as to intuitively experience the difference in hearing levels and warn the experiencer to maintain good protective measures and use habits to protect hearing; wherein the first hearing state is simulated by the noise protection state and noise conditions selected by the experiencer.

[0158] Through the interaction between the two mannequin heads and the display screen, the experiencer can clearly feel the changes in the hearing status, and then deeply understand the harm of not taking protective measures as required. And guide the experiencer to explore ways to improve themselves by adjusting the noise protection status, truly achieving an immersive interactive experience with strong practicality. It should be noted that the data acquisition and processing of the second mannequin head is exactly the same as that of the first mannequin head. The only difference is that the experiencer can have different settings for the corresponding noise protection status and noise conditions of the two, so as to experience the impact of the noise protection method on the hearing status through this difference.
