This method includes steps S1, constructing an audiometric device and an audiometric environment, and calibrating the audiometric device and the audiometric environment using a calibrated artificial ear; S2, the audiometric device automatically arranges the frequency point and the test ear, and automatically adjusts the pure tone frequency and intensity according to the subject's response, performs a self-service pure tone hearing threshold test, obtains the initial test results, and records them; S3, obtains historical test data, constructs an age cycle, and constructs a screening time error influence model based on different age cycles; S4, adjusts the initial test results, obtains the new adjustment results as the final hearing screening results, and outputs them.

[0003] With respect to the above scheme, the present invention finds that the calibration data of the above scheme is only obtained based on the user's response. According to the user's self-service pure tone audiometry test, the user's subjectivity may affect the accuracy of the calibration judgment. The above scheme does not have a pure tone echo collection device, and does not use the audiometry device to directly collect pure tone data. It cannot meet the objectivity of the automatic calibration of the transducer for pure tone audiometry, which is easy to cause calibration errors. At the same time, due to the lack of objectivity, the above scheme cannot timely judge the transducer calibration timing, which easily increases the possibility of generating erroneous audiometry result data, resulting in a decrease in the accuracy of pure tone audiometry. Summary of the invention

[0004] In view of the above-mentioned technical deficiencies, the object of the present invention is to provide a method and system for automatic calibration of a pure tone audiometry transducer.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides an automatic calibration method for a pure tone audiometry transducer, comprising the following steps: Step 1, basic transducer detection: During the current audiometry, the usage data of the transducer is collected, and then the usage data of the transducer is analyzed to obtain the usage index of each hertz of the transducer, and according to the usage index of the transducer, it is determined whether the transducer needs to be calibrated.

[0006] Step 2: Basic calibration of the transducer: If the transducer needs to be calibrated, at the end of the current audiometry, when the earphone is placed in the earphone stand, a calibration test is performed through the earphone corresponding interface on the earphone stand to collect the basic calibration data of the transducer, thereby performing basic calibration of the transducer.

[0007] Step 3: Accurately calibrate the transducer: Collect the usage data of the calibrated transducer, analyze the usage data of the calibrated transducer, and obtain the calibration accuracy index to determine whether the transducer calibration is accurate. If the transducer calibration is not accurate, perform accurate calibration of the transducer.

[0009] Preferably, the determination of whether the transducer needs to be calibrated is specifically made as follows: obtaining the usage index of each fault-free audiometry at each Hz from a database, calculating the average value to obtain the standard audiometry usage index of each Hz, and calculating the average value of the standard audiometry usage index of each Hz to obtain the standard usage index.

[0010] If the usage index of a certain Hz currently being measured is less than the standard usage index, it indicates that the transducer currently being measured has a fault at that Hz, and the Hz of the frequency currently being measured is recorded as the fault Hz of the transducer currently being measured, and the historical fault Hz of the transducer is obtained from the database, and the historical fault Hz of the transducer and the fault Hz of the current measurement are summarized to obtain the fault Hz of the target converter, and the total number of fault Hz of the transducer is obtained by statistics, and the total number of fault Hz of the transducer is divided by the total number of Hz in the database to obtain the fault rate of the transducer. If the fault rate of the transducer is greater than the preset basic calibration failure rate, basic calibration is performed.

[0011] Preferably, the basic calibration data of the transducer is collected, and the specific collection process is as follows: the basic calibration data of the transducer includes the value of each test input decibel of each fault Hz at the input end of the transducer, the value of the output decibel corresponding to each test input decibel of each fault Hz at the input end, the value of each test input decibel of each fault Hz at the output end, and the value of the output decibel corresponding to each test input decibel of each fault Hz at the output end.

[0012] A pure tone of each test input decibel of each fault hertz is sent to the corresponding interface of the earphone on the earphone stand through the earphone, and the output decibel corresponding to each test input decibel of each fault hertz at the transducer input end is collected through the sensor of the corresponding interface of the earphone on the earphone stand, so as to obtain the value of each test input decibel of each fault hertz at the transducer input end and the corresponding output decibel value.

[0013] Pure tones of each test input decibel of each fault Hz are sent to the earphone through the corresponding interface of the earphone on the earphone stand, and the output decibels corresponding to each test input decibel of each fault Hz at the output end of the transducer are collected through the sensor in the earphone, so as to obtain the values ​​of each test input decibel of each fault Hz at the output end of the transducer and the corresponding output decibel values.

[0015] On the other hand, the present invention provides an automatic transducer calibration system for pure tone audiometry, comprising the following modules: a transducer basic detection module, for collecting transducer usage data during the current audiometry, and then analyzing the transducer usage data to obtain a usage index of each hertz of the transducer, and judging whether the transducer needs to be calibrated based on the transducer usage index.

[0019] 2. The present invention performs basic calibration by judging the fault hertz, and judges whether to perform precise calibration by the precise calibration rate of the input pure tone. The two judgment methods increase the accuracy of fault judgment. At the same time, accurate calibration judgment helps to correct basic calibration errors, thereby increasing calibration accuracy and reducing the possibility of generating erroneous audiometry result data.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] according to Figure 1As shown, the present invention provides an automatic calibration method for a pure tone audiometry transducer, comprising the following steps: Step 1, basic detection of the transducer: during the current audiometry, the usage data of the transducer is collected, and then the usage data of the transducer is analyzed to obtain a usage index of each Hz of the transducer, and according to the usage index of the transducer, it is determined whether the transducer needs to be calibrated.

[0025] In a specific embodiment, the transducer usage data is collected, and the specific collection process is as follows: the transducer usage data includes the user number of the current audiometry and the output decibel corresponding to each input decibel at each Hz of the current audiometry, a receiver is set at the audiometry earphone port, when the earphone emits a pure tone, the pure tone reflected in the audiometry process is received by the receiver, when the user performs a pure tone audiometry through the transducer, the medical staff records the user number, and the medical staff adjusts and records the input decibel and Hz of each collection of the current audiometry, and then collects and records the output decibel of each collection through the receiver, so as to obtain the output decibel corresponding to each input decibel at each Hz of the current audiometry.

[0026] In a specific embodiment, the use data of the transducer is analyzed, and the specific analysis process is as follows: according to the user number, the user's historical audiometry record is obtained from the database, the user's historical audiometry record includes the historical output decibels corresponding to the user's input decibels, the average value of the historical output decibels corresponding to the user's input decibels is calculated to obtain the standard output decibel corresponding to the user's input decibels, and the output decibel corresponding to each input decibel at each Hz of the current audiometry is substituted into the usage index calculation formula In the example, the usage index of the current audiometric transducer is obtained. , a is the number of Hertz, , , The output decibel corresponding to the input decibel b under the current audiometric Hz a, b is the number of the input decibel, , , is the standard output decibel for input decibel b, is the weighting factor for the preset input decibel b, , .

[0027] It should be noted that the number of pure tone usages at each input decibel is obtained from the database , .

[0028] In a specific embodiment, the determination of whether the transducer needs to be calibrated is specifically made as follows: obtaining the usage index of each fault-free audiometry at each Hz from a database, calculating the average value to obtain the standard audiometry usage index of each Hz, and calculating the average value of the standard audiometry usage index of each Hz to obtain the standard usage index.

[0029] If the usage index of a certain Hz currently being measured is less than the standard usage index, it indicates that the transducer currently being measured has a fault at that Hz, and the Hz of the frequency currently being measured is recorded as the fault Hz of the transducer currently being measured, and the historical fault Hz of the transducer is obtained from the database, and the historical fault Hz of the transducer and the fault Hz of the current measurement are summarized to obtain the fault Hz of the target converter, and the total number of fault Hz of the transducer is obtained by statistics, and the total number of fault Hz of the transducer is divided by the total number of Hz in the database to obtain the fault rate of the transducer. If the fault rate of the transducer is greater than the preset basic calibration failure rate, basic calibration is performed.

[0030] Step 2: Basic calibration of the transducer: If the transducer needs to be calibrated, at the end of the current audiometry, when the earphone is placed in the earphone stand, a calibration test is performed through the earphone corresponding interface on the earphone stand to collect the basic calibration data of the transducer, thereby performing basic calibration of the transducer.

[0031] In a specific embodiment, the basic calibration data of the transducer is collected, and the specific collection process is as follows: the basic calibration data of the transducer includes the value of each test input decibel of each fault Hz at the input end of the transducer, the value of the output decibel corresponding to each test input decibel of each fault Hz at the input end, the value of each test input decibel of each fault Hz at the output end, and the value of the output decibel corresponding to each test input decibel of each fault Hz at the output end.

[0032] A pure tone of each test input decibel of each fault hertz is sent to the corresponding interface of the earphone on the earphone stand through the earphone, and the output decibel corresponding to each test input decibel of each fault hertz at the transducer input end is collected through the sensor of the corresponding interface of the earphone on the earphone stand, so as to obtain the value of each test input decibel of each fault hertz at the transducer input end and the corresponding output decibel value.

[0033] Pure tones of each test input decibel of each fault Hz are sent to the earphone through the corresponding interface of the earphone on the earphone stand, and the output decibels corresponding to each test input decibel of each fault Hz at the output end of the transducer are collected through the sensor in the earphone, so as to obtain the values ​​of each test input decibel of each fault Hz at the output end of the transducer and the corresponding output decibel values.

[0034] In a specific embodiment, the basic calibration of the transducer is performed, and the specific calibration process is as follows: the value of each test input decibel of each fault hertz at the input end of the transducer is divided by the corresponding output decibel to obtain the output power calibration factor of each test input decibel of each fault hertz of the transducer, the current output power of each test input decibel of each fault hertz of the transducer is obtained from the database, the current output power of each test input decibel of each fault hertz of the transducer is multiplied by the output power calibration factor to obtain the target output power of each test input decibel of each fault hertz of the transducer.

[0035] Divide the value of each test input decibel of each fault hertz at the output end of the transducer by the corresponding output decibel to obtain the sensitivity calibration factor of each test input decibel of each fault hertz of the transducer, obtain the current sensitivity of each test input decibel of each fault hertz of the transducer from the database, multiply the current sensitivity of each test input decibel of each fault hertz of the transducer by the sensitivity calibration factor to obtain the target output power of each test input decibel of each fault hertz of the transducer.

[0036] The number of times each fault Hertz is used and the number of times each test input decibel of each fault Hertz is used are obtained from the database, and the number of times each test input decibel of each fault Hertz is used is divided by the number of times each fault Hertz is used to obtain the usage rate of each test input decibel of each fault Hertz; if the usage rate of a certain test input decibel of a certain fault Hertz is lower than the preset decibel usage rate, the test input decibel of the fault Hertz is recorded as the low-frequency usage input decibel; if the usage rate of a certain test input decibel of a certain fault Hertz is greater than or equal to the preset decibel usage Hertz, the test input decibel of the fault Hertz is recorded as the high-frequency usage input decibel; the sensitivity of each high-frequency usage input decibel of each fault Hertz is adjusted to the target sensitivity corresponding to each high-frequency usage input decibel, and the sensitivity of each low-frequency usage input decibel of each fault Hertz is adjusted to the target output power corresponding to each high-frequency usage input decibel.

[0037] It should be noted that if the transducer is normal, the test input decibel is equal to the output decibel, and the ratio of the test input decibel to the output decibel is one to one. At the same time, the staff can debug and simulate the listening test environment. For example, a noise barrier may be set in front of the sensor or transmitter of the corresponding interface of the earphone on the headphone stand to make the ratio of the test input decibel to the output decibel two to one. If a noise barrier is set, the output power calibration factor and the sensitivity calibration factor shall be multiplied by the corresponding ratio at the same time.

[0038] Step 3: Accurately calibrate the transducer: Collect the usage data of the calibrated transducer, analyze the usage data of the calibrated transducer, and obtain the calibration accuracy of the transducer to determine whether the transducer calibration is accurate. If the transducer calibration is not accurate, perform accurate calibration of the transducer.

[0039] In a specific embodiment, the calibrated transducer usage data is analyzed, and the specific analysis process is as follows: the calibrated transducer usage data includes the user number of the future first listening test after the transducer is calibrated and the output decibel of each input decibel at each Hz, the user who will be listened to for the first time after the transducer is calibrated is referred to as the future first user, and the historical listening records of the future first user are obtained from the database according to the future first user number, including the historical output decibels corresponding to the input decibels of the future first user, the maximum output decibel data corresponding to the input decibels of the future first user is recorded as the upper limit of the standard output decibel range of each input decibel, and the minimum decibel data corresponding to the input decibels of the future first user is recorded as the lower limit of the standard output decibel range of each input decibel, thereby obtaining the standard output decibel range of each input decibel.

[0040] If the output decibel of a certain input decibel at a certain Hz in the first listening test after the transducer is calibrated in the future belongs to the standard output decibel range of the output decibel, the input decibel at that Hz is regarded as the normal input decibel, the number of normal input decibels at each Hz is obtained by statistics, the number of normal input decibels at each Hz is summarized to obtain the normal input decibel number, the input decibels at each Hz are summarized to obtain the total input decibel number, the normal input decibel number is divided by the total input decibel number to obtain the calibration accuracy of the transducer.

[0041] In a specific embodiment, the determination of whether the transducer calibration is accurate is carried out as follows: the calibration accuracy of each normally calibrated transducer is obtained from a database, and the standard calibration accuracy is obtained by calculating the average value. If the transducer calibration accuracy index is greater than or equal to the standard calibration accuracy index, it indicates that the calibration is accurate. If the transducer calibration accuracy index is less than the standard calibration accuracy index, it indicates that the calibration is inaccurate and the transducer is precisely calibrated.

[0042] In a specific embodiment, the precise calibration of the transducer is performed, and the specific calibration process is as follows: if the basic calibration of the transducer adopts changing the output power, then according to the target sensitivity analysis process of the basic calibration process, the target sensitivity of the precise calibration is obtained, and the sensitivity of the transducer is changed to the target sensitivity of the precise calibration.

[0043] If the basic calibration of the transducer adopts the change of sensitivity, the target output power of the precise calibration is obtained according to the target output power analysis process of the basic calibration process, and the output power of the transducer is changed to the target output power of the precise calibration.

[0044] according to Figure 2 As shown, the present invention provides an automatic calibration system for a pure tone audiometry transducer, comprising the following modules: a basic transducer detection module, a basic transducer calibration module, a precise transducer calibration module and a database.

[0045] The transducer basic detection module is connected to the transducer basic calibration module and the database respectively, and the transducer precise calibration module is connected to the transducer basic calibration module.

[0046] The basic transducer detection module is used to collect the usage data of the transducer during the current audiometry, and then analyze the usage data of the transducer to obtain the usage index of each hertz of the transducer, and determine whether the transducer needs to be calibrated according to the usage index of the transducer.

[0047] The transducer basic calibration module is used when the transducer needs to be calibrated. When the current audiometry is completed and the earphone is placed in the earphone stand, a calibration test is performed through the earphone corresponding interface on the earphone stand to collect the basic calibration data of the transducer, thereby performing basic calibration of the transducer.

[0048] The transducer precision calibration module is used to collect the calibrated transducer usage data, analyze the calibrated transducer usage data, and obtain the calibration accuracy of the transducer, so as to judge whether the transducer calibration is accurate. If the transducer calibration is not accurate, the transducer is precisely calibrated.

[0049] A database is used to store the user's historical audiometry records, the number of pure tone uses for each input decibel, the use index of each trouble-free audiometry for each hertz, each historical trouble hertz of the transducer, the total number of hertz, the current output power of each test input decibel for each trouble hertz of the transducer, the current sensitivity of each test input decibel for each trouble hertz of the transducer, the number of uses for each trouble hertz, the number of uses for each test input decibel for each trouble hertz, the historical audiometry records of future first-time users, and the calibration accuracy of each normally calibrated transducer.
