Description

Technical Field

[0001] The present invention belongs to the technical field of tinnitus attention ability training, and in particular relates to a tinnitus patient's attention ability training method, system and storage medium. Background Art

[0002] Tinnitus is a common clinical symptom, which is characterized by the subjective perception of sound in the ear when there is no objective external sound source or electrical stimulation, often described as a hissing or buzzing sound. According to epidemiological data, there are more than 120 million tinnitus patients in China, and the onset of tinnitus tends to be younger. Tinnitus has only a slight effect on most patients, but some patients experience anxiety, depression, and even mental illness or suicide. Due to the complex causes of tinnitus and unclear mechanisms, there is still no widely used, convenient and efficient method for treating tinnitus in clinical practice.

[0003] In the prior art, tinnitus masking therapy (TMT), habituation therapy (THT) and cognitive behavioral therapy (CBT) are often used to treat tinnitus. TMT mainly adjusts and controls the activity of the body's external hair cells, which changes the patient's tinnitus perception. Generally, narrow-band noise corresponding to the patient's tinnitus frequency is used to increase the loudness of the sound to cover the sound of the tinnitus, so that the patient cannot feel the tinnitus temporarily. It should be noted that masking therapy is not effective for all tinnitus patients and is also affected by the accuracy of individual reports of tinnitus patients. For example, the tinnitus frequency of some patients is variable, and the tinnitus matching sound and masking sound cannot be adjusted in time during the treatment process, making the treatment effect insignificant. In addition, the persistence of the masking treatment effect is poor, and it only temporarily relieves the impact of tinnitus. Usually, when the masking sound is removed, the patient will notice the tinnitus sound again, and its effect can only last for a few seconds to tens of minutes. Habituation therapy requires a long treatment cycle, which mainly consists of two parts: consultation therapy and sound therapy. Consultation therapy is mainly to change the patient's anxiety, irritability and worry, and guide them to face the tinnitus symptoms. Reducing psychological pressure is of great significance for clinical treatment; sound therapy is essentially incomplete masking, advocating that the intensity of masking sound cannot cover up tinnitus and coexist with tinnitus; the biggest disadvantage of this treatment method is that the treatment time is long, and basically it is necessary to ensure that the treatment is not less than eight hours a day; generally one and a half years is the most suitable to achieve the expected clinical effect. Although habituation therapy has a wide range of applications, it is time-consuming, and most patients do not comply and pay enough attention to it, so it is not easy to complete the treatment.

[0004] In addition to the above-mentioned treatment methods, drugs and transcranial magnetic stimulation (TMS) are also used in the treatment of tinnitus, but there is still no widely used, convenient and efficient method. Although medical staff usually remind patients to divert their attention in daily life and not pay too much attention to the tinnitus, there is currently no method for patients to actively divert their attention. The above-mentioned masking method and habituation method only allow patients to passively divert their attention. In addition, it is worth noting that tinnitus patients are often accompanied by attention deficits, which are manifested as a decrease in sustained attention ability. The attention of tinnitus patients is passively directed to the tinnitus side. Long-term tinnitus will damage the patient's ability to turn attention to novel stimuli; severe tinnitus will damage cognitive control processing rather than automatic processing. The binaural integration ability of tinnitus patients for information, auditory selective attention ability and auditory sustained attention ability are all damaged. Because tinnitus patients pay more attention to internal interference sounds, this attention deficit hinders patients from habituating to interference sounds, making patients unable to adapt to this abnormal hearing; but there is currently no solution for the attention deficit of tinnitus patients on the market. Summary of the invention

[0005] The main purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art and to provide a method, system and storage medium for training the attention ability of tinnitus patients. The present invention combines visual stimulation and auditory stimulation to perform attention training on tinnitus patients, thereby improving the attention ability of tinnitus patients, improving the attention deficit of tinnitus patients and alleviating the tinnitus condition; at the same time, according to the response of the tinnitus patients, the attention ability score, tinnitus condition score and psychological condition score are calculated and evaluated, thereby ensuring the effectiveness of the training effect.

[0006] In order to achieve the above object, the present invention adopts a method for training the attention ability of tinnitus patients, comprising the following steps:

[0007] Use conventional pure tone audiometry equipment to obtain the tinnitus side and the average hearing threshold of both ears of the tinnitus patient, and obtain the comfortable loudness of the tinnitus patient;

[0008] The tinnitus status scores and psychological status scores of tinnitus patients were collected through questionnaires;

[0009] Based on the comfortable loudness of tinnitus patients, the attention ability of tinnitus patients was tested to obtain the attention ability score;

[0010] According to the tinnitus side and comfortable loudness of the tinnitus patients, the tinnitus patients were trained with auditory and visual stimulations. After the training, the tinnitus patients were tested for their attention ability.

[0011] Conduct attention training for tinnitus patients multiple times, and adjust the parameters of the next attention training based on the reaction time and accuracy of the attention ability test after each training session;

[0012] After the attention training, an attention ability test was conducted to evaluate the effectiveness of the attention training.

[0013] As a preferred technical solution, the tinnitus side S refers to the side of the tinnitus patient's perception of sound when tinnitus occurs, including a single ear side and a double ear side; the single ear side includes a left ear side and a right ear side;

[0014] The average hearing threshold includes the average hearing threshold L1 of the left ear and the average hearing threshold L2 of the right ear, and the acquisition method is:

[0015] Use conventional pure tone audiometry equipment to examine the left ear and the right ear respectively, send out pure tone signals of different loudness at multiple set frequencies, and repeatedly adjust the loudness parameters of the set frequencies until the tinnitus patient can just hear the loudness value of the sound at the set frequency, then average the loudness values ​​of multiple set frequencies to obtain and record the average hearing threshold L1 of the left ear and the average hearing threshold L2 of the right ear;

[0016] The tinnitus condition score is obtained using the Tinnitus Disability Scale and the Visual Analog Scale;

[0017] The psychological status scores were obtained using the Beck Depression Inventory and the Beck Anxiety Inventory.

[0018] As a preferred technical solution, the set frequencies include 0.5kHz, 1kHz, 2kHz, and 4kHz.

[0019] As a preferred technical solution, the attention ability test of the tinnitus patient is specifically:

[0020] A fixed fixation point is presented on the display device, and the tinnitus patient is required to keep fixation, and the tinnitus patient is prompted to pay attention to the sound on a certain ear side;

[0021] The auditory signal generator generates pure tone auditory stimuli of two frequencies and adjusts them to the comfortable loudness L3 for tinnitus patients;

[0022] The pure tone auditory stimuli of two frequencies are randomly transmitted to the audio player with equal probability, and played in the left ear or right ear of the tinnitus patient with equal probability;

[0023] Tinnitus patients identify auditory stimuli played in the left or right ear and respond via a feedback device;

[0024] The reaction time and accuracy of tinnitus patients were recorded, and the attention ability score was calculated.

[0025] As a preferred technical solution, the two frequencies are 1500 Hz and 300 Hz respectively; the duration of the auditory stimulation is 200 ms; the fixation point display time is 300 ms;

[0026] The recording of the reaction time and accuracy of the tinnitus patient refers to recording the reaction of the tinnitus patient during the test period;

[0027] The calculation formula of the attention ability score S is:

[0028]

[0029] The unit of response time is milliseconds;

[0030] The attention ability test is conducted in multiple groups, each group is conducted multiple times; each test lasts 2000ms; each test interval is 300ms; and each group test interval is 2-5min.

[0031] As a preferred technical solution, if the tinnitus patient has unilateral tinnitus, attention training for the unilateral tinnitus is performed, specifically:

[0032] A fixed fixation point is presented on the display device, and the tinnitus patient is required to keep fixating on it, and the tinnitus patient is also required to pay attention to the sound on the non-tinnitus side and the visual stimulation that appears on the non-tinnitus side at the same time;

[0033] Using an auditory signal generator to generate white noise, auditory stimulation of 300 Hz, 1000 Hz, and 1500 Hz and adjusting the loudness to a comfortable level L3 for tinnitus patients; using a visual signal generator to generate visual stimulation on a display device;

[0034] White noise auditory stimulation was used as the target auditory stimulation and was presented to the non-tinnitus side of the tinnitus patients simultaneously with the visual stimulation;

[0035] The auditory stimulation is presented to the tinnitus patient multiple times with equal probability through an audio player. When the non-tinnitus side receives the target auditory stimulation and visual stimulation at the same time, the patient responds through the feedback device within the training time, and the reaction time and accuracy are recorded.

[0036] If the tinnitus patient has tinnitus on both ears, attention training on both ears should be performed, specifically:

[0037] A fixed fixation point is presented on the display device, and the tinnitus patient is required to keep fixating on it, and the tinnitus patient is required to pay attention to the sound on a certain ear side and the visual stimulation appearing on the same ear side at the same time;

[0038] Using an auditory signal generator to generate white noise, auditory stimulation of 300 Hz, 1000 Hz, and 1500 Hz and adjusting the loudness to a comfortable level L3 for tinnitus patients; using a visual signal generator to generate visual stimulation on a display device;

[0039] White noise auditory stimulation was used as the target auditory stimulation and was presented simultaneously with the visual stimulation on the same ear side of the tinnitus patient;

[0040] Auditory stimuli are presented to tinnitus patients multiple times with equal probability through an audio player. When one ear of the tinnitus patient receives the target auditory stimulation and visual stimulation, the patient responds through the feedback device within the training time, and the reaction time and accuracy are recorded.

[0041] As a preferred technical solution, the auditory signal generator uses Adobe Audition 3.0 software to generate auditory stimulation, and the sampling rate of Adobe Audition 3.0 software is 44.1kHz; the visual signal generator uses Matlab2016b software to generate visual stimulation; the fixation point display time is 300ms; the duration of the auditory stimulation and visual stimulation is 200ms;

[0042] The visual stimulus is a white dot, the center of which is 4° visual angle to the left or right of the display area of ​​the display device, and the diameter corresponds to a visual angle of 1°;

[0043] The attention training is performed in multiple groups, each group is performed multiple times; each training session lasts for 2000ms; the interval between each training session is 300ms; and the interval between each group of training sessions is 2-5min.

[0044] As a preferred technical solution, the parameters for adjusting the next attention training are specifically:

[0045] Based on the reaction time and accuracy of the tinnitus patient during each training session, if the accuracy is higher than a set threshold, the duration of the auditory stimulation and visual stimulation during the attention training is shortened to increase the difficulty; if the accuracy is lower than the set threshold, the duration of the auditory stimulation and visual stimulation during the attention training is prolonged to reduce the difficulty; the shorter the duration of the auditory stimulation and visual stimulation, the greater the difficulty;

[0046] The evaluation of the attention training effect is specifically as follows:

[0047] If the final attention ability score is less than the initial attention ability score, it is considered that attention training has an improvement effect on the attention deficit of tinnitus patients;

[0048] If the final tinnitus condition score value is less than the initial tinnitus condition score value or the tinnitus condition is reported to be improved after attention training, it is considered that attention training has an improvement effect on the tinnitus condition of the tinnitus patient;

[0049] If the final psychological condition score is less than the initial psychological condition score, it is determined that attention training has an improving effect on the mood of tinnitus patients.

[0050] On the other hand, the present invention also provides an attention ability training system for tinnitus patients, comprising a display device, a feedback device, an audio player and an attention ability training module; the attention ability training module stores an attention ability training program for executing the above-mentioned attention ability training method for tinnitus patients;

[0051] The attention ability training program includes an input unit, a questionnaire unit, an attention test unit, an attention training unit and an evaluation unit;

[0052] The input unit is used to obtain the tinnitus side and the average hearing threshold of both ears of the tinnitus patient; and obtain the comfortable loudness of the tinnitus patient according to the average hearing threshold of both ears;

[0067] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0068] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0069] like Figure 1 As shown, this embodiment provides a method for training the attention ability of tinnitus patients, comprising the following steps:

[0070] S1. Use conventional pure tone audiometry equipment to obtain the tinnitus side and the average hearing threshold of both ears of the tinnitus patient, and obtain the comfortable loudness of the tinnitus patient;

[0071] The tinnitus side S of tinnitus patients refers to the side on which the patients feel the sound when they have tinnitus, which is divided into unilateral and bilateral sides; the unilateral side is further divided into left and right sides; it can be obtained by asking the tinnitus patients.

[0072] The average hearing threshold is divided into the average hearing threshold of the left ear L1 and the average hearing threshold of the right ear L2, and the acquisition method is:

[0073] Use conventional pure tone audiometry equipment to examine the left and right ears respectively, emit pure tone signals of different loudness at multiple set frequencies, and repeatedly adjust the loudness parameters of the set frequencies until the tinnitus patient can just hear the loudness value of the sound at the set frequency. Then average the loudness values ​​of multiple set frequencies to obtain and record the average hearing threshold L1 of the left ear and the average hearing threshold L2 of the right ear.

[0074] For the purpose of protecting hearing and improving the targetedness of treatment, the loudness of auditory stimulation should not be set too high or too low. Therefore, based on the average hearing thresholds L1 and L2 of both ears of tinnitus patients, the initial auditory stimulation loudness is given first, and then the operator is asked to repeatedly adjust the loudness to find the loudness L3 that the tinnitus patients feel comfortable with.

[0075] In this embodiment, a conventional pure tone audiometry device is used to test the average hearing threshold of both ears at four frequencies of 0.5 kHz, 1 kHz, 2 kHz, and 4 kHz.

[0076] S2. Collect the tinnitus status scores and psychological status scores of tinnitus patients through questionnaires;

[0077] In this embodiment, the tinnitus condition score of tinnitus patients is evaluated by using the Tinnitus Disability Inventory (THI) and the Visual Analog Scale (VAS) to assess the severity of tinnitus; the evaluation criteria are as follows: for THI, there are 25 questions with a total score of 100 points, and the severity of tinnitus is graded according to the scale score of 0-100 (0-16 is mild, 18-36 is mild, 38-56 is moderate, 58-76 is severe, and 78-100 is extremely severe); for VAS, it is used to evaluate the loudness and annoyance of tinnitus, with a score of 0 to 10 points, and the higher the score, the greater the impact of tinnitus.

[0078] For the psychological status scores of tinnitus patients, the Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) were used to assess the depression and anxiety status of tinnitus patients; both scales have 21 questions, and each question is scored from 0 to 3; for the Beck Depression Inventory, a total score of 0 to 13 is normal, 14 to 19 is mild depression, 20 to 28 is moderate depression, and 29 to 63 is severe depression; for the Beck Anxiety Inventory, a total score of 45 points or higher is considered to be suffering from anxiety.

[0079] S3. Based on the comfortable loudness of the tinnitus patients, the attention ability test is conducted on the tinnitus patients to obtain the attention ability score;

[0080] Before conducting attention training, it is necessary to conduct an attention ability test (pre-test) on tinnitus patients in the initial state to facilitate the evaluation of the subsequent training effect. The pre-test is specifically as follows:

[0081] A fixed fixation point is presented on the display device, and the tinnitus patient is required to keep fixation, and the tinnitus patient is prompted to pay attention to the sound on a certain ear side;

[0082] The auditory signal generator generates pure tone auditory stimuli of two frequencies and adjusts them to the comfortable loudness L3 for tinnitus patients;

[0083] The pure tone auditory stimuli of two frequencies are randomly transmitted to the audio player with equal probability, and played in the left ear or right ear of the tinnitus patient with equal probability;

[0084] Tinnitus patients identify auditory stimuli played in the left or right ear and respond via a feedback device;

[0085] The reaction time and accuracy of tinnitus patients were recorded, and the attention ability score was calculated.

[0086] In this embodiment, Figure 2 As shown in the figure, the attention ability test was performed on the left ear of the tinnitus patient. First, the tinnitus patient wore headphones and sat 60 cm in front of the computer screen and was asked to look at a fixed fixation point generated on the computer screen (such as Figure 2, lasting for 300ms), and prompt the tinnitus patient to pay attention to the sound on the left ear side (such as "Please press the left button if you hear a high-frequency sound on the left side", "Please press the right button if you hear a low-frequency sound on the left side"); then use Adobe Audition 3.0 software to generate pure tone auditory stimulation with a frequency of 1500Hz and 300Hz and a loudness of L3, and play it in the left or right ear with equal probability through the headphones worn by the tinnitus patient (lasting for 200ms); when the tinnitus patient receives the auditory stimulation on one ear and it is the same as the prompt, press the corresponding button to respond, and automatically record the response of the tinnitus patient during the test time (i.e., the blank screen time of 2000ms in the figure), including the reaction time and accuracy, and then calculate the attention score S, the calculation formula is:

[0087]

[0088] The unit of response time is milliseconds;

[0089] In this embodiment, a total of 4 groups of attention ability tests are conducted, each group of attention ability tests are tested 36 times, each test time is 2000ms; each test interval time is 300ms; each test interval time is 2-5min. In this embodiment, the interval time between each group is 2 minutes. After the interval time ends, the tinnitus patient presses a button to enter the next group of tests.

[0090] S4. Use auditory and visual stimulation to train the tinnitus patients’ attention according to their tinnitus side and comfortable loudness. After the training, test the tinnitus patients’ attention ability.

[0091] When conducting attention training, different methods are used to conduct attention training according to the different tinnitus sides of the tinnitus patients:

[0092] S41. If the tinnitus patient has unilateral tinnitus, attention training for that unilateral ear is performed, specifically:

[0093] A fixed fixation point is presented on the display device, and the tinnitus patient is required to keep fixating on it, and the tinnitus patient is also required to pay attention to the sound on the non-tinnitus side and the visual stimulation that appears on the non-tinnitus side at the same time;

[0094] Using an auditory signal generator to generate white noise, auditory stimulation of 300 Hz, 1000 Hz, and 1500 Hz and adjusting the loudness to a comfortable level L3 for tinnitus patients; using a visual signal generator to generate visual stimulation on a display device;

[0095] White noise auditory stimulation was used as the target auditory stimulation and was presented to the non-tinnitus side of the tinnitus patient simultaneously with the visual stimulation;

[0096] Auditory stimuli are presented to tinnitus patients multiple times with equal probability through an audio player. When the non-tinnitus side receives the target auditory stimuli and visual stimuli, it responds through the feedback device within the training time, and the reaction time and accuracy are recorded.

[0097] like Figure 3 As shown in Figure 1, assuming that the tinnitus patient's right ear is the tinnitus side, when conducting single-ear attention training, first generate a fixed fixation point on the computer screen (i.e. Figure 3 The tinnitus patients were asked to keep their gaze on the target auditory stimulus (i.e., white noise, lasting 200ms) played in their left ear and visual stimulus (i.e., Figure 3 The white dots in the figure last for 200ms. Figure 3 The tester presses a button within 2000ms of the blank screen in the middle to react, and records the reaction time and accuracy; multiple groups of single-ear attention training are performed, each group is performed multiple times, each training lasts for 2000ms, and each training interval is 300ms. In this embodiment, a total of 8 groups of single-ear attention training are performed, each group is subjected to 48 audio-visual stimulations, and each group of training is separated by 2min before entering the next group of training.

[0098] S42. If the tinnitus patient has tinnitus on both sides of the ears, conduct attention training on both sides of the ears, specifically:

[0099] A fixed fixation point is presented on the display device, and the tinnitus patient is required to keep fixating on it, and the tinnitus patient is required to pay attention to the sound on a certain ear side and the visual stimulation appearing on the same ear side at the same time;

[0100] Using an auditory signal generator to generate white noise, auditory stimulation of 300 Hz, 1000 Hz, and 1500 Hz and adjusting the loudness to a comfortable level L3 for tinnitus patients; using a visual signal generator to generate visual stimulation on a display device;

[0101] White noise auditory stimulation was used as the target auditory stimulation and was presented simultaneously with the visual stimulation on the same ear side of the tinnitus patient;

[0102] Auditory stimuli are presented to tinnitus patients multiple times with equal probability through an audio player. When one ear of the tinnitus patient receives the target auditory stimulation and visual stimulation, the patient responds through the feedback device within the training time, and the reaction time and accuracy are recorded.

[0103] like Figure 4 As shown in Figure 1, assuming that the tinnitus patient has bilateral lateralization, when conducting bilateral lateral attention training, first generate a fixed fixation point on the computer screen (i.e. Figure 4The tinnitus patient was asked to keep looking at the target auditory stimulus (i.e., white noise, lasting 200ms) and the visual stimulus (i.e., white noise, lasting 300ms) on one ear. Figure 4 The white dots in the figure last for 200ms. Figure 4 The tester then presses a button within 2000ms of the blank screen in the middle of the screen to react, and records the reaction time and accuracy; multiple groups of binaural attention training are performed, each group is performed multiple times, each training lasts for 2000ms, and each training interval is 300ms. In this embodiment, a total of 8 groups of binaural attention ability training are performed, each time 48 audio-visual stimulations are performed, and each group is separated by 2 minutes before entering the next group of training.

[0104] The auditory signal generators in this embodiment all use Adobe Audition 3.0 software with a sampling rate of 44.1kHz (16 bits); the visual signal generator uses Matlab 2016b software; the fixation point display time is 300ms; the duration of auditory stimulation and visual stimulation is 300ms; the generated visual stimulus is a white dot, the center of which is 4° visual angle to the left or right of the display area of ​​the display device, and the diameter corresponds to a visual angle of 1°.

[0105] S5, conducting attention training for the tinnitus patient multiple times, and adjusting the parameters of the next attention training based on the reaction time and accuracy rate obtained from the attention ability test after each training;

[0106] The parameters of the attention training process are the presentation time of all stimuli, ranging from 100ms to 300ms; the initial duration when starting attention training is 300ms, based on the reaction time and accuracy of tinnitus patients during each training session; if the accuracy is higher than the set threshold, the duration of auditory and visual stimuli during attention training is shortened to increase the difficulty; if the accuracy is lower than the set threshold, the duration of auditory and visual stimuli during attention training is extended to reduce the difficulty; the shorter the duration of auditory and visual stimuli, the greater the difficulty.

[0107] In this embodiment, when the accuracy rate is lower than 70%, the presentation time of the audiovisual stimulation is increased by 10 ms each time; otherwise, the presentation time of the audiovisual stimulation is shortened by 10 ms each time to adjust the difficulty of training.

[0108] S6. After the attention training is completed, an attention ability test is conducted to evaluate the effectiveness of the attention training.

[0109] After the attention training is completed, the tinnitus patients need to be tested for attention ability again (post-test) to evaluate the effect of attention training; the above post-test is used to obtain the final attention ability score, tinnitus condition score and psychological condition score for evaluation:

[0110] If the final attention ability score is less than the initial attention ability score, it is considered that attention training has an improvement effect on the attention deficit of tinnitus patients;

[0111] If the final tinnitus condition score is less than the initial tinnitus condition score or the tinnitus condition is reported to be improved after attention training, it is considered that attention ability training has an improvement effect on the tinnitus condition of the tinnitus patient;

[0112] If the final psychological status score is less than the initial psychological status score, it is determined that attention training has an improving effect on the mood of tinnitus patients.

[0113] It should be understood that, according to the evaluation results and the actual needs of tinnitus patients, this method can be implemented in cycles, such as taking 7 days as a cycle, conducting attention ability test and attention training on the first day, only attention training on the second to sixth days, and conducting attention ability test after attention training on the seventh day, and so on, until the desired effect is achieved.

[0114] It should be noted that, for the sake of convenience, the aforementioned method embodiments are all expressed as a series of action combinations, but those skilled in the art should know that the present invention is not limited to the described order of actions, because according to the present invention, certain steps can be performed in other orders or simultaneously.

[0115] like Figure 5 As shown, another embodiment of the present invention provides an attention ability training system for tinnitus patients, including a display device, a feedback device, an audio player and an attention ability training module; the attention ability training module stores an attention ability training program for executing the above-mentioned attention ability training method for tinnitus patients;

[0116] The attention ability training program includes input unit, questionnaire unit, attention test unit, attention training unit and evaluation unit;

[0117] The input unit is used to obtain the tinnitus side and the average hearing threshold of both ears of the tinnitus patient; and according to the average hearing threshold of both ears, the comfortable loudness of the tinnitus patient is obtained;

[0118] The questionnaire unit is used to collect the tinnitus condition scores and psychological condition scores of tinnitus patients through questionnaires;

[0119] The attention test unit is used to test the attention ability of tinnitus patients based on the comfortable loudness of the tinnitus patients to obtain the attention ability score;

[0120] The attention training unit is used to perform attention training on tinnitus patients using auditory stimulation and visual stimulation according to the tinnitus side and comfortable loudness of the tinnitus patients, and to test the attention ability of the tinnitus patients after the training; the attention training is performed on the tinnitus patients for multiple times, and the parameters of the next attention training are adjusted based on the reaction time and accuracy obtained from the attention ability test after each training;

[0121] The evaluation unit is used to conduct attention ability test after the attention training is completed and to evaluate the effect of the attention training.

[0122] It should be noted that in the implementation of the attention ability training system for tinnitus patients in the above embodiment, the logical division of each program module is only an example.
