The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0022] The power module 100 is used to generate direct current of a predetermined voltage, and in the embodiments of the application, the power module 100 is used to supply power to other modules, which comprises a DC-DC circuit and an LDO circuit. The DC-DC circuit is used to reduce the input 12V direct current to 5V. The LDO circuit comprises a low-dropout linear regulator and peripheral elements, and is used to further reduce the 5V direct current output by the DC-DC circuit to 3.3V.

[0023] The DC-DC circuit comprises a synchronous buck converter U5 and peripheral elements connected to the synchronous buck converter. In a preferred embodiment, the synchronous buck converter U5 is a TPS54202DDCR chip, the input voltage of which is 12V direct current. Two voltage dividing resistors R25 and R66 are connected to the left side of the synchronous buck converter, which reduces the direct current to 5V. The high-frequency noise is filtered by filter capacitors C4 and C37 to stabilize the output voltage. The 2nd inductor L2 is connected to the right side of the synchronous buck converter as an energy storage element, which cooperates with the switch tube integrated in the chip to realize voltage conversion of Buck topology. The DC-DC circuit outputs purer 5V direct current through LC filtering and optimization of circuit structure layout.

[0024] The LDO circuit is based on a low-dropout linear regulator KF33BDT-TR chip, the input end of which is connected to the 5V direct current output by the DC-DC circuit, and the resistors R21 and R22, the capacitors C5 and C7 and the capacitors C9 and C10 connected to the input end and the output end of the KF33BDT-TR chip are used to further reduce the 5V direct current output by the DC-DC circuit to 3.3V direct current.

[0025] The audio processing module comprises a digital chip U1, a crystal oscillator circuit and a reset circuit, wherein the digital chip U1 is powered by 3.3V direct current.

[0026] The crystal oscillator circuit is used to provide a reference clock signal to the digital chip U1, and the reset circuit is used to generate a reset signal to restore the digital chip U1 to the initial state when the digital chip U1 is powered on.

[0027] The digital chip U1 internally burns a notch audio file preparation program, which is used to process an initial audio file into a notch audio file for treatment.

[0028] In the embodiment of the present application, as an optional implementation, the digital chip U1 is an R7FA4E10B2CFM chip. In order to facilitate understanding of the constitution of the system, the connection mode of the pins on the chip is described. The No. 33 pin SWDIO, the No. 25 pin RES and the No. 32 pin SWCLK on the chip are connected to the program burning port, which is used to burn the program for the digital chip U1. In the embodiment of the present application, the program is used to burn the basic control program of each module in the system and the notch audio file preparation program.

[0029] The No. 12 pin, the No. 13 pin, the No. 14 pin and the No. 15 pin on the chip are connected with the storage module, which is used to read and write the audio file from the storage module and store the prepared audio file.

[0030] Specifically, the storage module is a serial flash memory circuit, which includes an SPI Flash memory chip U2, which is used to store and read the audio file.

[0031] In order to ensure that the digital chip U1 is in the initial state each time the program is burned, the No. 25 pin RES on the R7FA4E10B2CFM chip is connected with the reset circuit.

[0032] Among them, the No. 6 pin, the No. 7 pin, the No. 8 pin and the No. 9 pin of the R7FA4E10B2CFM chip are connected to the crystal oscillator circuit. The crystal oscillator circuit provides a reference clock signal for the chip after being powered on, which is used as the Specifically, in the present application, processing the initial audio file into a notch audio file for treatment includes the following steps: Firstly, a notch frequency range is constructed based on a predetermined center frequency; the predetermined center frequency is the tinnitus center frequency of the patient, wherein the notch frequency range is determined by a left notch edge frequency f1 and a right notch edge frequency f2, and the left notch edge frequency f1 and the right notch edge frequency f2 are related to the predetermined center frequency f0 as follows: c The following relationship is met:

[0033] In order to understand the principle of notch frequency range determination in the present application, a medical concept, critical bandwidth, needs to be introduced, which refers to the bandwidth range within which the human ear processes sound signals as a whole, and sound signals within a frequency band centered on a certain frequency are processed as a whole, while sound signals outside the frequency band are processed independently, and the frequencies corresponding to the edge positions at both ends of the critical bandwidth are critical frequencies.

[0034] The critical bandwidth has frequency dependence, and the bandwidth is narrower in the low frequency region and wider in the high frequency region. In the prior art, the measurement of the critical bandwidth generally adopts a masking experiment, which determines the critical point at which the threshold no longer changes when the noise bandwidth increases by measuring the threshold at which pure tone is masked by narrowband noise.

[0035] In acoustics and signal processing, an octave refers to the interval between two frequencies with a frequency ratio of 2:1. That is, if a frequency is f, then the frequency one octave higher is 2f, and the frequency one octave lower is f / 2. In the present application, the critical bandwidth is limited to 3 / 8 of an octave, which is close to 1 / 3-1 / 2 of the critical bandwidth, which can cover enough frequency range to trigger the suppression effect, and also avoids the confusion of frequency bands caused by too wide bandwidth.

[0036] Then, the audio in the initial audio file whose frequency is within the range of the notch frequency range is filtered.

[0037] For example, a peak filter is set at each of the two end notches corresponding to the notch frequency range, and the audio in the initial audio file whose frequency is within the range of 3 / 8 of an octave is filtered to eliminate the corresponding frequency band.

[0038] For example, the critical bandwidth of 5000 Hz is 867.5 Hz. 5452.5-4585.0=867.5 Hz Specifically, the frequency boundaries are 4585.0 Hz and 5452.5 Hz, and the critical bandwidth is 867.5 Hz.

[0039] Then, the audio in the initial audio file whose frequency is within the range of the notch frequency range is filtered.

[0040] For the convenience of understanding, the concept of lateral inhibition principle is introduced. It refers to the mechanism that the auditory system enhances the frequency contrast through mutual inhibition of adjacent neurons, so that the edge of the highlighted frequency band in music can make the human ear more sensitive to the difference between adjacent frequency bands, thereby strengthening the boundary feeling of the "cut". The present application enhances the perception of the auditory system to the frequency boundary by increasing the audio loudness near the edge of the cut, thereby effectively activating the lateral inhibition. It can be understood that, generally, a 20db loudness gain is performed, and when the audio dynamic range is limited, it can be appropriately reduced to 10 or 15db, and the specific value can be determined according to the monitoring and treatment progress of the patient's auditory system.

[0041] Finally, in order to prevent audio distortion and avoid the hearing of "frequency response protrusion", the energy spectrum of each frequency band of the enhanced audio file is equalized to form a notch audio file.

[0042] The notch audio file processed and formed by the present application determines the center frequency according to the tinnitus of the patient, adopts a reasonable notch frequency range determination, enhances the perception of the auditory system to the frequency boundary by increasing the audio loudness near the edge of the cut, activates the lateral inhibition, and performs equalization processing according to the energy spectrum of each frequency band, so as to treat the individual tinnitus patients.
