Technical Field

The application relates to the technical field of hearing rehabilitation, in particular to a system for training pure tone threshold test skills.

Background

At present, how to accurately know the degree and the property of hearing loss of a patient with hearing impairment is an important basis for subsequent diagnosis and treatment. Clinically, the pure tone threshold hearing test method is the most commonly used hearing acquisition method, which is recommended by the hearing protection committee of the american society of eye, ear, nose and throat, also called the 10 liter 5 method, namely: first, an audible sound signal is given to a subject (patient), for example, 40dB is given to a subject whose hearing is estimated to be normal, and the sound intensity is sequentially reduced in 10dB steps until the subject cannot hear. And then taking 5dB as a first level, the steps are sequentially increased until the subject can just hear the step. Repeating the above steps until 3 reactions are obtained at the same intensity (minimum intensity), wherein the intensity is the hearing threshold (pure tone threshold) of the subject, and can reflect the hearing condition of the whole conduction path of the subject from the outer ear to the auditory center. The hearing loss of the subject can be quantitatively and qualitatively diagnosed through pure tone threshold audiometry, and an important basis is provided for subsequent diagnosis and treatment.

Pure tone threshold audiometry is a clinical skill that must be mastered by audiologists or audiologists alike. The correct wearing of the bone conduction earphone and the air conduction earphone is a precondition for accurately obtaining the hearing threshold, so that a qualified audiometer is cultivated, the skill operation method is required to be repeatedly practiced on the ears of a subject, and experience is accumulated by clinically encountering patients with different hearing loss types, so that the clinical operation skill is finally really mastered. At present, the training method for the audiologist is to enable students to mutually serve as subjects for training, and guide teachers to train one by one, so that occupied teacher resources are more, and the training cost is higher.

According to the system for training the pure tone threshold test skills, provided by the embodiment of the application, after a pure tone threshold test mode is selected on the subject model component by a audiometer panel component and a subject model component, according to the prompt corresponding to the selected pure tone threshold test mode, a bone conduction earphone and/or a gas conduction earphone can be worn on the subject model in the subject model component, the subject model component perceives the position information of the bone conduction earphone and/or the gas conduction earphone, judges whether the perceived position information is matched with the correctly worn position information mapped by the selected pure tone threshold test mode, and informs the audiometer of the perceived position information judgment result so as to enable the audiometer to acquire specific information whether the earphone is worn correctly or not; meanwhile, the channel information set by the audiometer panel component according to the selected pure-tone threshold audiometry mode is acquired, the channel information is compared with the correct channel information mapped by the selected pure-tone threshold audiometry mode, and the audiometer is informed of the set channel information judgment result, so that the audiometer can acquire whether the set channel information is correct or not.

As an alternative embodiment, 6 pure tone threshold audiometric mode control buttons are arranged on the control panel, and in the training process, the audiometer selects a corresponding pure tone threshold audiometric mode according to the actual skill training requirement.

The goal of learning is to have the learner learn the Hughson-Westlake threshold test method. The knowledge points involved are the basic method of pure tone threshold hearing. In practice, the knowledge point decomposition and practice module of the computer component simulates hearing curves giving different hearing loss degrees and configurations, so that students practice the following: selecting a test ear; selecting test frequency and testing sequence; a method for reducing the threshold value by ten liters and five searching; and controlling the duration and interval of sound emission, and recording the test result. In practice, the audiometer is used for operating basic function buttons on the audiometer panel assembly according to knowledge point decomposition and prompt of the practice module.

Exercise content 5

The learning objective is to let the learner learn the masked test principle and method. The knowledge points involved are part of the masked decision and test method. In the pure tone threshold hearing process, if the binaural hearing has a certain gap, when the ears are measured, the sound signal is transmitted to the cochlea on the opposite side without reaching the threshold, so that the sound is heard by the good ears to react. This hearing resulting from non-test ear engagement is cross-hearing. The purpose of masking is to remove the participation of non-test ears, resulting in a true threshold for the test ears. For air conduction, the masking decision principle is: masking is required when the difference between the unmasked air conduction threshold of the test ear and the bone conduction threshold of the non-test ear is greater than or equal to 40 dB. For bone conduction, masking is required when the difference between the air and bone conduction thresholds of the test ear is greater than 10 dB. The masking method is a Hood platform method. The basic method is as follows: masking noise is introduced into the non-test ear and the pure tone threshold of the opposite ear is measured. In practice, the hearing curves which need and do not need masking are simulated and given through a knowledge point decomposition and practice module, so that the audiometrist can practice the following: judging whether masking is needed, setting basic function buttons on the audiometer panel assembly when masking is needed, and masking a Hood platform; recording methods of test results and the like, and selecting whether masking is needed or not and the frequency of masking is needed by an audiometer according to knowledge point decomposition and prompts in a training module through a mouse in a computer component or a touch screen in a display screen component; according to the prompt, the audiometer operator exercises to operate each basic function button on the audiometer panel assembly during masking, and grasps the setting of the basic function buttons during masking and the masking operation method of the Hood platform. The operation of the audiometer can be displayed through the display screen assembly, audio and video data such as the type, frequency, intensity and the like of the corresponding sound signals are played through the loudspeaker, and whether the operation of the audiometer is correct or not is also prompted through the prompt sound sent by the loudspeaker.

The learning purpose is to enable the audiologist to master the record signs of the left and right ears, the air-guide bone guide and the masked non-masked measured threshold value, and master the evaluation standard of the hearing loss degree and the property at the same time, so as to explain the test result for the patient after the test is completed in the actual operation. The link can be presented in the forms of selection questions, judgment questions, question answers and the like which are arranged in the knowledge point decomposition and exercise module, and as an alternative embodiment, the exercise can select the presented selection questions through a mouse in a computer component or a touch screen in a display screen component, and whether the selection is correct or not can be prompted by sending a prompt tone through a loudspeaker.

in this embodiment, the comprehensive ability training module is configured to integrate and review courseware of the theoretical knowledge interpretation module and knowledge points in the knowledge point decomposition and training module. In this module, the audiologist will be exposed to a wide variety of clinical cases, such as: normal hearing, hearing loss of different nature, hearing loss of different degrees, hearing loss of different configurations. In the comprehensive training, an audiometer is required to practice the completion of the test according to a standard test flow. When the audiometer is wrong in testing steps or the testing method is wrong, the audiometer is reminded to correct in time. For example, if the audiometer is not clearly explained in the test requirement explanation link, the audiometer can continue the test and give corresponding reminding and guidance in the subsequent operation.

In this embodiment, as an alternative embodiment, the examination and performance analysis module combines with the actual needs of clinical audiometry, so that the audiometer can complete the audiometry of cases with different difficulties, thereby grading the level of mastery of the audiometer. The examination score can be judged based on the score of the score point of each audiometric step, and the weight of the score point examination question and the columnar score analysis chart of the examinee can be given out besides the total score.

According to the system for training the pure tone threshold test skills, disclosed by the embodiment of the application, an audiometer can conduct guidance and prompt according to the user interface displayed on the display screen component, is matched with operation exercises on the subject model component and the audiometer panel component, can independently complete learning of the pure tone threshold test skills, can autonomously learn the pure tone threshold test skills, furthest reduces dependence on a guiding teacher, or can realize proficiency in mastering the pure tone threshold test skills under the condition of not guiding a teacher, so that the labor cost required by training can be effectively reduced, and the teacher resources can be saved; meanwhile, as students can train pure tone threshold audiometry skills at any time, the training efficiency is high; furthermore, as the pure tone hearing test comprises a pure tone gas hearing test and a bone conduction hearing test, a learner is required to repeatedly practice the wearing operation of the bone conduction earphone and the gas conduction earphone in the test process, and simultaneously, the test is required to be performed by repeatedly giving a stimulus sound signal to a subject in the test, so that the hearing fatigue of the subject is easy to cause, the test accuracy is not high, and the test is performed by using the subject model component, so that the situation that the test accuracy is not high due to the fact that the stimulus sound signal is given repeatedly in the test, the subject receives the test repeatedly after hearing the test, and the hearing fatigue is caused is avoided; moreover, the subject model component can simulate different hearing loss conditions, so that audiologists practice abundant case types, and the situations that the hearing loss conditions encountered in clinical actual work are complex and various because the subjects are normal hearing people, the audiologists can only accumulate clinical experience on patients after going on duty, the training time is long, the training efficiency is low, and the patients are damaged are avoided; in addition, the situation that the bone conduction earphone and the air conduction earphone used in pure tone threshold audiometry are large in tension between the two yokes of the air conduction earphone, and the audiometer can cause damage to the subject possibly caused by repeated practice of the head of the subject can be avoided, and the situation that skin and hearing damage to the subject possibly caused by illegal operation such as improper wearing of the earphone and overlarge sound can be possibly caused by the operation of the audiometer by the audiometer at a beginner can be avoided.
