[0029] In order to make the technical solutions and beneficial effects of the present application more obvious and easy to understand, the following is a detailed description by listing specific embodiments. The drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which the present application belongs.
[0030] The present application improves the symptoms of hearing impairment by combining auditory stimulation and electrical stimulation. Hearing impairment may include tinnitus, hyperacusis, misophobia or phonophobia, hearing loss, etc. Tinnitus is mentioned in the following examples only for convenience, but it can be appreciated that the described methods and devices can be extended to any hearing impairment disease.
[0031] Figure 1 is an exemplary flow chart of a method for stimulating hearing impairment according to some embodiments of the present application.
[0032] At step 110, one or more target electrodes may be determined.
[0033] The target electrode is an electrode that stimulates neural tissue or other biological tissue by applying current or voltage. In some embodiments, the target electrode can be selected from one or more electrodes in an electrode array.
[0034] The electrode array may be composed of one or more electrodes arranged in a matrix or array. In some embodiments, the electrode array may be prepared to have a corresponding shape according to the shape of the stimulated part. For example, assuming that the stimulated part is the tongue, the electrode array may be set to a symmetrical shape with a width from wide to narrow; for another example, assuming that the stimulated part is the face, the electrode array may be set to a curved shape that fits the face; for another example, if the stimulated part is the hand, the electrode array may be set to a clip shape. For another example, if the stimulation part is a nerve, the electrode array may be set to a square, circular, porous shape, etc. The shape of the electrode array is not specifically limited herein.
[0035] In some embodiments, the number of electrodes in the electrode array may be a power of 2 or 34. The number and arrangement of electrodes in the electrode array may be set according to actual conditions and are not specifically limited here. Figure 2 Schematic diagram of an exemplary electrode array according to some embodiments of the present application. Figure 2 As shown, the electrode array 200 has a shape in which the width along direction A is narrowed from wide, and can be placed on the back of the patient's tongue to electrically stimulate the patient's tongue. The electrode array 200 includes 34 electrodes, the left half includes 17 electrodes, and the right half includes 17 electrodes. The electrodes in the left half and the electrodes in the right half are arranged symmetrically. In this way, the sensitive area of the back of the tongue can be better covered, the sensitivity of the nerve to the frequency of electrical stimulation can be increased, and the therapeutic effect of the electrical stimulation unit can be enhanced.
[0036] Figure 3 is a schematic diagram of an exemplary target electrode according to some embodiments of the present application. Figure 3 As shown, Figure 316 target electrodes 202, 204, 206, 208, 210, 212, 214, 216, 221, 223, 226, 228, 230, 232, 234 and 236 are shown in FIG. The 16 target electrodes are selected from Figure 2 A portion of the 34 electrodes in the electrode array shown in FIG.
[0037] In some embodiments, the target electrode may be formed by connecting a plurality of electrodes in an electrode array.
[0038] Figure 4 is a schematic diagram of an exemplary target electrode according to some embodiments of the present application. Figure 4 As shown, the electrode array 400 and Figure 2 In some embodiments, all or part of the electrodes in the left half of the electrode array 200 can be connected by wires to form a target electrode, and all or part of the electrodes in the right half of the electrode array 200 can be connected by wires to form a target electrode. Figure 4 As shown, the electrodes 201, ..., 217 on the left side of the electrode array 400 are connected by wires to form a target electrode; the electrodes 221, ..., 237 on the right side of the electrode array 400 are connected by wires to form a target electrode. In this case, the two target frequencies can be respectively corresponded to the target electrodes on the left side of the electrode array and the target electrodes on the right side of the electrode array, or the same target frequency can be simultaneously corresponded to the target electrodes on the left side and the target electrodes on the right side. When electrical stimulation is performed, surface stimulation can be achieved, thereby increasing the stimulation area for the patient.
[0039] In some embodiments, the target electrodes may be determined based on the actual situation of the patient. For example, the sensitivity of the patient's area to be stimulated may be measured in advance, and if the sensitivity is high, relatively fewer target electrodes may be determined; for another example, for patients with more severe symptoms, relatively more target electrodes may be determined.
[0040] In some embodiments, the number and position of the target electrodes can be manually selected or set by the doctor, or can be automatically or semi-automatically generated. For example, the doctor can adjust the number and position of the target electrodes in real time according to the patient's historical treatment situation; for another example, the target electrodes can be automatically generated through machine learning according to the historical treatment situation of the historical patient; for another example, one or several target electrode schemes can be automatically generated through machine learning according to the historical treatment situation of the historical patient, and further selected and determined by the doctor.
[0041] At step 120 , an audio file may be obtained.
[0042] The audio file can be used to perform audio stimulation on the hearing-impaired patient and generate an electrical stimulation signal accordingly. In some embodiments, the audio file may include music (e.g., songs, light music, piano music, etc.), environmental sounds (e.g., the sound of running water, birds singing, rain, etc.), human voices (e.g., recordings of performances, sounds of communication, etc.), etc. In some embodiments, the audio file may include synthesized sounds, for example, the audio file may include sounds synthesized from human voices and music. In some embodiments, the audio file may be a sound customized according to the cause, severity, duration of symptoms, etc. of the patient's tinnitus. By way of example only, the audio file may be customized to include at least part of the tinnitus frequency or remove the tinnitus frequency.
[0043] In some embodiments, the frequency range of the audio file is 200 Hz to 20 KHz, for example, 200 Hz, 500 Hz, 1000 Hz, 1500 Hz, 2 KHz, 4 KHz, 8 KHz, 10 KHz, 15 KHz, 20 KHz, etc.
[0044] In some embodiments, the audio file may be pre-stored in a memory and retrieved from the memory when used, or may be generated when used.
[0045] In step 130, one or more target frequency points within a predetermined time range may be determined according to the acquired audio file.
[0046] The target frequency point is a point in the audio file that represents its frequency. For example, the frequency points of an audio file with a frequency range of 200 Hz to 500 Hz may include 200 Hz, 250 Hz, 300 Hz, 350 Hz, 400 Hz, 450 Hz, 500 Hz, etc.
[0047] In some embodiments, the predetermined time may be a manually set time or a predetermined time. The predetermined time may be 1 s, 50 ms, 40 ms, 20 ms, 10 ms, etc. As an example only, assuming that the predetermined time is 50 ms, one or more segments may be determined from the audio file, each segment having a duration of 50 ms.
[0048] In some embodiments, one or more target frequency points may be determined based on the audio files within the predetermined time. For example, the target frequency point may be determined based on the frequency range of the audio files within the predetermined time. Figure 5 and its related description; for another example, the audio file within the predetermined time can be evenly divided by n segmentation points, and the target frequency point can be determined according to the frequency represented by the segmentation point. For details, see Figure 6 and its related description;
[0049] In some embodiments, FFT can be used to determine the target frequency. Specifically, the audio file is first cut and processed to obtain multiple audio sub-files (for example, each 50ms); FFT calculation is performed on each audio sub-file to convert the time domain signal into the frequency domain, display the amplitude and phase of different frequency components, and obtain the spectrum; the spectrum power is calculated from the FFT result to determine the extreme value and peak of the power value; based on the maximum power, the frequency point exceeding the power threshold (for example, 1 / 3 of the maximum power) can be determined as the candidate frequency point; the determined peak is matched with the candidate frequency point. In some embodiments, the determined peak can be compared with the candidate frequency points before and after it, and the frequency point that is closer to it is matched. The candidate frequency point that matches the determined peak is determined as the target frequency point. The audio file is analyzed by FFT, and the target frequency point is determined by using the extreme value and peak detection of the spectrum power to ensure the effectiveness and pertinence of the stimulation.
[0050] In step 140, operating parameters of one or more target electrodes are determined according to one or more target frequencies.
[0051] In some embodiments, the operating parameters of the target electrode may include one or more of the operating time of the target electrode, the waveform of the electrical stimulation of the target electrode, the voltage of the target electrode, the frequency of the target electrode, and the pulse width of the target electrode.
[0052] The working time of the target electrode is the time during which the target electrode electrically stimulates the patient. In some embodiments, the working time of the target electrode can be determined by the following formula:
[0053] Ti=T*(i / (1+2+...n)),
[0054] Where n represents the number of frequencies; i represents the sequence of the target frequencies corresponding to the target electrodes, which are numbered from largest to smallest; T is the scheduled time, and Ti is the working time of the target electrode. The working time of each target electrode can be determined by the above formula.
[0055] The voltage of the target electrode can be determined according to the patient's tolerance. For example, if the patient has a high tolerance, a relatively high voltage can be used to enhance the effect of electrical stimulation. For another example, the voltage can be gradually increased from low to high according to the patient's adaptability, thereby improving the patient's tolerance and further enhancing the treatment effect.
[0056] The voltage of the target electrode may be in the voltage range of 5 V to 40 V (eg, 5 V, 10 V, 20 V, 30 V, 40 V).
[0057] The waveform of the electrical stimulation of the target electrode may include a square wave, a sine wave, a triangle wave, etc. The pulse width of the target electrode may also be determined according to the patient's tolerance, and the pulse width may be adjusted by adjusting the duty cycle, which may be in the range of 10%-90%. By setting the duty cycle in this numerical range, the output of the output target electrode may be precisely controlled, thereby reducing energy loss and improving the efficiency of electrical stimulation.
[0058] In some embodiments, a target electrode corresponds to one or more target frequencies. Figure 3 The 16 target electrodes 202, 204, 206, 208, 210, 212, 214, 216, 221, 223, 226, 228, 230, 232, 234 and 236 correspond to the frequencies 2837 Hz, 2754 Hz, 3224, 3138, 3637, 3482, 2880, 3886, 2674, 2588, 3052, 2966, 3396, 3310, 3766 and 3680, respectively. For another example, Figure 2 The 17 electrodes in the left half can be connected as a target electrode, corresponding to the displayed target frequencies 2837, 2794, 2754, 2714, 3224, 3181, 3138, 3095, 3637, 3559, 3482, 3439, 2880, 3929, 3886, 3809; the 17 electrodes in the right half can be connected as a target electrode, corresponding to the displayed target frequencies 2764, 2631, 2588, 2545, 2837, 3052, 3009, 2966, 2923, 3396, 3353, 3310, 3267, 3766, 3723, 3680, 2468. In some embodiments, the target frequency corresponding to the target electrode in the right half can be the same as the target frequency corresponding to the target electrode in the left half.
[0059] In some embodiments, for the target frequency determined by FFT, the pulse width of the target electrode can be determined according to the peak that matches the target frequency. When multiple peaks match the same target frequency, their power is accumulated. For the frequency that is not matched, there is no stimulation waveform in this time period, and the pulse width can also be considered to be 0us. After accumulating the power of all matching target frequencies, the pulse width is allocated. The pulse width range can be from 0us to 500us, depending on the frequency band. When in the high frequency band, the pulse width is suppressed by the frequency, such as the maximum pulse width of 10KHz is 100us, the maximum pulse of 5KHz is 200us, and the pulse of 500us appears at the target frequency below 2KHz. 0us-500us non-0us is evenly distributed. If there are 5 target frequencies, the power from low to high is 100us, 200us, 300us, 400us, 500us according to the judgment. After the target electrode completes the pulse width allocation, it is stimulated one by one from the low frequency point to the high frequency point. Taking a cycle of 50ms as an example, the stimulation time of each target electrode is 50000us / 34=1470us=1.47ms. When the pulse width is 0, there is no stimulation, but it is necessary to wait for the corresponding time. Each target frequency point is stimulated as one pulse. Combining the pulse width allocation with the frequency characteristics makes the entire stimulation process both scientific and efficient.
[0060] At step 150, electrical stimulation and audio stimulation may be performed simultaneously according to the audio file and the operating parameters of the target electrode.
[0061] In some embodiments, a predetermined time range can be determined, and the patient can be subjected to electrical stimulation and audio stimulation simultaneously according to the audio file within this time range and the working parameters of the target electrode. In some embodiments, the patient can also be subjected to electrical stimulation and audio stimulation simultaneously according to the sequence of predetermined time according to the audio files within multiple predetermined time ranges and the working parameters of the target electrode. In some embodiments, the patient can also be subjected to electrical stimulation and audio stimulation simultaneously in a cycle according to the audio files within one or several predetermined time ranges and the working parameters of the target electrode.
[0062] In some embodiments, the audio file can be transmitted to the patient through bone conduction headphones, acoustic headphones, hearing aids, vibratory acoustic devices, maskers, ear implants, speakers, etc., so as to provide audio stimulation to the patient. At the same time, the current generated according to the working parameters of the target electrode is transmitted to the patient through the target electrode to electrically stimulate the patient.
[0063] It should be noted that the above description of the process of the method for stimulating hearing impairment is only for example and explanation, and does not limit the scope of application of this specification. For those skilled in the art, various modifications and changes can be made to the above process under the guidance of this specification. However, these modifications and changes are still within the scope of this specification. For example, steps 110 and 120 can be interchangeable, and one or more target electrodes can be determined after obtaining the audio file.
[0064] Figure 5 It is an exemplary flow chart of a method for determining a target frequency according to some embodiments of the present application.
[0065] At step 510 , a frequency threshold of the audio file within a predetermined time range may be determined.
[0066] In some embodiments, the frequency threshold can be determined based on the frequency of the audio file within a predetermined time range. For example, the component (e.g., 1 / 4, 1 / 3, 1 / 2, 2 / 3) of the maximum frequency of the audio file (e.g., the main frequency component) within the predetermined time range can be determined as the frequency threshold.
[0067] In some embodiments, the frequency threshold may be adjusted according to actual conditions. For example, when the number of target electrodes is relatively small, the frequency threshold may be set relatively large, and vice versa.
[0068] In step 520, frequency points whose frequencies are greater than a frequency threshold may be determined as candidate frequency points.
[0069] In step 530, one or more target frequency points may be determined based on the candidate frequency points.
[0070] In some embodiments, all or part of the candidate frequency points may be determined as target frequency points. Specifically, when the number of candidate frequency points is equal to the number of target electrodes, all candidate frequency points may be determined as target frequency points; when the number of candidate frequency points is greater than the number of target electrodes, the candidate frequency points may be matched in order of frequency from smallest to smallest until the number of target electrodes is the same, and the candidate frequency points that match the target electrodes are determined as target frequency points.
[0071] Figure 6 It is an exemplary flow chart of a method for determining a target frequency according to some embodiments of the present application.
[0072] In step 610, the audio files within a predetermined time range may be evenly divided using the division points.
[0073] In some embodiments, the highest and lowest frequencies of the audio file within a predetermined time range may be determined, and the frequency range between the highest and lowest frequencies may be evenly divided using the division points.
[0074] In step 620, the frequency represented by the segmentation point may be determined as the target frequency point.
[0075] In some embodiments, the number of segmentation points is equal to the number of target electrodes, in which case the frequency represented by the segmentation points can be determined as the target frequency point. In some embodiments, the number of segmentation points is greater than the number of target electrodes, in which case the segmentation points can be matched in order of frequency from smallest to smallest until the number of target electrodes is the same, and the frequency represented by the segmentation points matched with the target electrodes is determined as the target frequency point.
[0076] As an example only, the frequency range of the audio file is 500Hz-5KHz, the number of target electrodes is 34, and the number of split points can be 34. Then the target frequency points can be 500, 636, 773, 909, 1045, 1182, 1318, 1455, 1591, 1727, 1864, 2000, 2136, 2273, 2409, 2545, 2682, 2818, 2954, 3091, 3227, 3364, 3500, 3636, 3773, 3909, 4045, 4182, 4318, 4454, 4591, 4727, 4864 and 5000, which divides the audio file into 34 parts on average.
[0077] Alternatively, in some embodiments, the target frequency point can be determined according to the audio file according to an exponential increase allocation method. The exponential increase allocation method means that the intervals between adjacent frequencies are not uniform, but increase as the frequency increases. The calculation of each frequency follows a certain growth factor, so that the frequency distribution is uniform and has an exponential characteristic throughout the range. For example, the frequency range of the audio file is 500Hz-5KHz, the number of target electrodes is 34, and the number of split points can be 34. Then the audio file can be divided into 34 parts of 500, 548, 600, 657, 719, 787, 862, 944, 1034, 1132, 1239, 1357, 1486, 1627, 1782, 1951, 2137, 2340, 2562, 2806, 3072, 3364, 3684, 4034, 4417, 4837, 5297, 5800, 6351, 6955, 7616, 8340, 9132 and 10000 according to the exponential increase distribution method.
[0078] The exponential increase allocation method is used to determine the target frequency points. On the one hand, the points can be evenly distributed in the lower and higher frequency ranges to ensure that the entire range of audio files from 500Hz to 10KHz is covered; more dense target frequency points are provided in the high frequency band, which helps to accurately analyze and process high-frequency signals; the human ear's perception of audio frequencies is nonlinear, and using the exponential increase allocation method to process audio files can better simulate the human ear's sensitivity to different frequencies, making the frequency allocation more in line with the actual listening experience; and it can reduce spectrum leakage and distortion, and improve the accuracy of subsequent audio file analysis (for example, FFT).
[0079] In some embodiments, a hearing impairment stimulation device includes an audio stimulation unit and an electrical stimulation unit.
[0080] The audio stimulation unit can be used to obtain an audio file; determine one or more target frequency points within a predetermined time range according to the audio file; and perform audio stimulation according to the audio file. The electrical stimulation unit is used to determine the working parameters of one or more target electrodes according to one or more target frequency points, the target electrodes corresponding to the target frequency points; and perform electrical stimulation while performing audio stimulation according to the working parameters of the target electrodes.
