Description

Technical Field

[0001] The present invention relates to the technical field of graded hearing examination and intervention, and in particular to a multi-terminal-based self-service graded hearing examination system and a control method thereof. Background Art

[0002] At present, in the field of medical devices, many types of audiometers have appeared. However, due to technical limitations, existing audiometers generate inspection sound instructions according to the operation of the subject, and the digital signal of the inspection sound instruction needs to be converted into an analog signal before it can be sent to the external earphones, so that the earphones can output inspection or intervention sounds to the subject. This working mode directly leads to an audiometer that can only test one subject at a time, and cannot perform synchronous or asynchronous inspections on multiple subjects at the same time. In addition, there are many defects in the facilities, equipment, personnel qualifications, and operation quality of personalized hearing tests, resulting in a wide range of hearing test quality and accuracy. Now it is generally necessary to rely on the judgment or operation of the tester to conduct different hearing tests. The audiometer itself cannot automatically switch the inspection path according to the inspection information of different subjects, that is, it cannot complete the operation of graded inspection and intervention treatment for multiple subjects at the same time, and the work efficiency is extremely low. As a result, traditional audiometers and their detection methods cannot fundamentally solve the urgent need for large-scale hearing tests faced by an aging society. In addition, the method of conducting hearing tests by downloading an APP on a mobile phone is subject to the influence of the wide variety of mobile phones and earphones, machine use and maintenance, audiometric environment noise, machine working stability, operation, etc., resulting in very low hearing test accuracy and difficulty meeting the quality requirements of medical-level hearing tests.

[0003] Pure tone hearing tests are conducted in a standard silent room (for example, according to the requirements of Type 4 audiometer in the national standard GB / T7341.1-2010 "Electroacoustic Audiometric Equipment Part 1: Pure Tone Audiometer"), which depends on the cognitive and judgment abilities of the subjects. How to eliminate hearing test errors caused by cognitive defects of the subjects and environmental noise and improve test reliability is a difficult problem in large-scale hearing screening.

[0004] Although the prevalence of presbycusis is high, it can be detected early through timely hearing screening, and intervention can be carried out through fitting hearing aids. However, nearly 50% of hearing screening patients fail the first screening. If the patients are directly referred without graded examination, it will bring great pressure to the higher-level referral medical institutions. How to deal with the follow-up work of the 50% of elderly people who fail will face great challenges. Summary of the invention

[0039] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0040] See also Figure 1-5 , the embodiment of the present invention includes:

[0041] A multi-terminal-based self-service graded hearing examination system, whose structure includes: a remote control processing unit, multiple offline terminal units and audiometric earphone units matched with the terminals. One remote control processing unit and multiple offline terminal units perform two-way digital communication synchronously or crosswise, so that multiple subjects in the same or different places can perform synchronous or asynchronous hearing screening, cognitive function assessment, hearing threshold test and hearing loss assessment by themselves.

[0042] In terms of structural performance, the remote control processing unit can be a high-performance computer with a computing speed of up to 100 million times per second. It is equipped with a digital sound signal generator module DSG, a digital signal processor module DSP, up to 100Tbz of memory and a central processing unit module CPU and an image processor module GPU to achieve high-speed parallel and cross computing.

[0043] The remote control processing unit is also equipped with an artificial intelligence machine deep learning module to optimize the performance of the remote control processing unit according to the actual usage area, scene, time period, crowd and other characteristics to meet the needs of massive personalized inspections. With the help of 5G ultra-high-speed wireless transmission of digital signals, the two-way digital wireless communication between the inspection digital signal issued by the remote control processing unit and the operation digital signal issued by the terminal can be carried out synchronously or in queue. Even if tens of thousands of people use it at the same time, the human eyes and ears can basically not detect the millisecond-level signal lag.

[0044] A remote control processing unit is connected to multiple offline terminal units at the same time, and ensures that each offline terminal unit has a unique digital signal input and output channel and data storage corresponding to the remote control processing unit. Each subject can register a unique account through the offline terminal unit to obtain efficient and high-quality personalized services.

[0045] The remote control processing unit is configured with a noise impact correction module, a large database storage and management module BDSM, a digital signal transmission and receiving module ST / R connected to the offline terminal unit, and an output port I / O connected to external databases / centers including but not limited to the National Big Health Data Center.

[0046] The noise impact correction module of the remote control processing unit is based on the statistics of a large sample of the population. Through experimental calibration, the numerical correspondence between the measured hearing threshold volume corresponding to the frequency under different environmental noises and the frequency and hearing threshold volume detected by the same population in a standard silent room environment is used to convert the actual noise intensity in the ear canal of the subject in an environment with a noise level below 60 decibels and the hearing test threshold volume into the pure tone detection threshold volume in a standard silent room environment (for example, according to the requirements of type 4 audiometers in the national standard GB / T7341.1-2010 "Electroacoustic Audiometry Equipment Part 1: Pure Tone Audiometer"), so that the hearing test results can be expressed in terms of the hearing threshold under environmental noise or in terms of the hearing threshold under the corresponding standard silent environment to meet different application requirements.

[0047] Functionally, the remote control processing unit provides a hearing screening function module, a cognitive function assessment function module, a hearing threshold test function module and a hearing loss assessment function module. The subject can perform human-computer interaction and switch the inspection path of each functional module through the offline terminal unit to generate and / or process the corresponding hearing examination / intervention digital signal and output the digital signal.

[0048] The offline terminal unit is equipped with an operating system module, a digital-to-analog converter D / A module, a digital signal transmitting and receiving module, and a sound card module. The subject can issue work instructions to the remote control processing unit through the offline terminal unit and switch the left and right earphones. The terminal can be a touch screen, a tablet, or a mobile phone, and the offline terminal unit can also be connected to external devices such as a display screen, a keyboard, and a power supply.

[0049] The offline terminal unit is also configured with the following modules:

[0050] The brain-computer interface module connects the subject to the offline terminal unit and / or the remote control processing unit to feedback the sound perception information of the hearing test and / or intervention, seek and provide technical services, popular science information, etc.;

[0051] The subject identity verification module and the remote control processing unit account form a complete information security system;

[0052] The service fee payment module is interconnected with the remote control processing unit and / or connected to other payment systems.

[0053] The offline terminal unit is connected to the audiometric earphone unit via wired or Bluetooth wireless connection.

[0054] The audiometric earphone unit includes a left earphone and a right earphone. The speaker or receiver in the earphone converts the analog audio signal of the offline terminal unit into a sound signal and inputs it into the ear canal of the subject. The earphone can be a press-on ear type or an in-ear type. The earphone is equipped with a Bluetooth module and a noise meter module for detecting the noise entering the ear canal. The noise meter is interconnected with the offline terminal unit and / or the remote control processing unit.

[0055] The three units, namely the remote control processing unit, the offline terminal unit and the earphone, must be regularly calibrated for system signals to ensure that the hearing test signals are accurate and reliable.

[0056] A control method for a multi-terminal self-service graded hearing test system, the steps of which include:

[0057] (1) One or more subjects in the same or different places register or log in to an account through an offline terminal unit. The account can store all the subject's previous testing, intervention, referral and other information.

[0058] (2) The subjects wear headphones in an environment with a noise level below 60 decibels, and operate the offline terminal unit by themselves and issue commands to synchronously or asynchronously control the hearing screening, cognitive function assessment, hearing threshold test and hearing loss assessment modules of the remote control processing unit to conduct graded hearing examinations for different subjects;

[0059] (2.1) Conduct a sweeping hearing screening: Conduct a hearing screening on the subjects. If all four frequency points are passed, the screening is considered passed; otherwise, the screening is considered failed. If the subjects pass the hearing screening, a follow-up plan is generated, and a follow-up examination is conducted once a year. Among them, 2%-5% of the subjects who pass the screening are randomly selected to undergo hearing screening again to verify the difference between the retests and perform a screening reliability analysis. If the subjects fail the hearing screening, proceed to step (2.2).

[0060] Among them, during the sweep-frequency hearing screening, no less than four screening frequency points can be selected or set according to the subject's age, occupation, relevant industry standards and other conditions, and the screening pass intensity value of each screening frequency point can be set to conduct hearing screening on the subject. When all screening frequency points pass, it is judged that the screening has passed, otherwise it is judged that the screening has failed.

[0061] For example: According to the national standard GB / T26341-2010, at the four frequency points of 500, 1000, 2000 and 4000Hz, the screening pass intensity value of each frequency point is set to 40dBHL.

[0062] (2.2) Conduct cognitive function assessment (assessment scale GPCO): If the assessment fails, generate a referral report and send the referral information to a specialized hospital or hearing service center for referral; if the assessment passes, proceed to step (2.3).

[0063] (2.3) Conduct hearing threshold test: including but not limited to covering the frequency range of 125-8000Hz or even up to 20000Hz ultra-high frequency and the intensity range of 30-90dBHL or even up to 120dBHL for extremely severe hearing loss, meeting the requirements of the national standard GB / T7341.1-2010 "Electroacoustic Audiometry Equipment Part 1: Pure Tone Audiometer" Type 4 audiometer. If the hearing threshold test is passed, a follow-up plan will be generated and a follow-up examination will be conducted once a year; if it fails, a recommended treatment plan (including recommendation to wear hearing aids, etc.) will be generated for intervention treatment, or a referral report will be generated and referred to a professional hospital or hearing service center.

[0064] (2.4) Generate a hearing examination assessment report based on hearing screening, cognitive function assessment and hearing threshold test information.

[0065] (3) Those who fail the online and offline graded hearing examinations will be referred to the offline graded hearing aid intervention pathway.

[0066] (3.1) When the cognitive function assessment fails: the specialized hospital or hearing service center configures a high-performance, fitable digital hearing aid based on the referral information to intervene in the subject; or, based on the referral information, synchronously or asynchronously regulates the remote control processing unit to intervene in the subject through the offline terminal unit and the audiometric headphone unit.

[0067] (3.2) When the hearing threshold test fails: Community service centers and other institutions configure digital hearing aids that do not require fitting according to the recommended treatment plan and conduct hearing aid intervention on the subject; or synchronously or asynchronously control the remote control processing unit based on the referral information to intervene in the subject through the offline terminal unit and the audiometric headphone unit. Regularly test and judge the intervention effect of the subject. If the intervention effect is poor, execute step (3.1).

[0068] (3.3) Obtain the subjects’ intervention feedback information, effect information, and satisfaction information, and generate a hearing aid intervention effect and satisfaction evaluation report.

[0069] (4) When performing the graded hearing test and intervention in steps (2)-(3), the remote control processing unit generates a hearing test / intervention digital signal according to the digital signal instruction issued by the offline terminal unit and sends it to the offline terminal unit; the digital-to-analog converter module and the sound card module of the offline terminal unit convert the hearing test / intervention digital signal into a hearing test / intervention analog signal, and the audiometric earphone unit converts the hearing test / intervention analog signal into a sound signal and inputs it into the ear canal of the subject; the subject feeds back the feedback digital signal to the remote control processing unit through the offline terminal unit according to the sound perception, so that the remote control processing unit adjusts the hearing test / intervention digital signal or switches the human-computer interaction test path. The subject can also seek technical service support from the remote control processing unit through the offline terminal unit.

[0070] (5) Automatically store hearing screening, testing, assessment and intervention information in the big database storage module of the cloud remote control processing unit.

[0071] (6) Subjects can download their own test results or hearing test assessment reports from their own account on the remote control processing unit to the terminal or mobile phone, tablet, or computer, including but not limited to text and graphics.

[0072] (7) The remote control processing unit is the brain of the system. The matching offline terminal unit and audiometric headphone unit, as well as the noise correction, are all complete systems that have been fixed after experimental calibration. During long-term use, the offline terminal unit and audiometric headphone unit can be calibrated regularly through the system's preset calibration procedures and indicators, thereby ensuring that large-scale hearing examinations can meet the high standards of medical-level accuracy.

[0073] The beneficial effect of the self-service graded hearing examination system based on multiple terminals and the control method thereof of the present invention is that multiple subjects in the same or different places can synchronously or asynchronously regulate a remote control processing unit through different offline terminal units to implement, switch and feedback hearing screening, cognitive function assessment, hearing threshold test and hearing loss assessment, thereby improving the work efficiency and service quality of professional hearing examinations, so as to achieve the high accuracy standards of medical-level hearing examinations and meet the needs of implementing the active health early examination and early intervention strategy in a large-scale aging society.
